+# claw-rag-mcp Standalone MCP Server — Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Build a standalone, PATH-installable MCP stdio server (`claw-rag-mcp`) that exposes RAG `rag_query` / `rag_stats` / `rag_ingest` / `rag_ingest_status` tools over a SQLite index shared with `claw-rag-service`.
+
+**Architecture:** New independent Rust project at `D:\tempo\claw-rag-mcp` (own Cargo workspace, own git repo, not inside claw-code). It path-depends on the existing `claw-rag-service` lib for indexing/embedding/search logic. Transport is a self-written minimal stdio MCP server (LSP `Content-Length` framing + JSON-RPC `initialize`/`tools/list`/`tools/call`), zero MCP SDK dependency, honoring the repo-wide `forbid(unsafe_code)` lint. Ingest runs as an in-memory async job so `rag_ingest` returns immediately and `rag_ingest_status` polls progress.
+
+**Tech Stack:** Rust 2021, tokio (macros/rt-multi-thread/io-std/io-util/sync/time), serde + serde_json, reqwest 0.12 (json, rustls-tls), `claw-rag-service` (path dep), rusqlite (transitive via claw-rag-service), tempfile (dev).
+
+## Global Constraints
+
+- Project lives at `D:\tempo\claw-rag-mcp` — **not** inside the claw-code repository. It is its own git repo (`git init` in Task 2). The only file changed inside claw-code is `claw-rag-service` (Task 1).
+- Path dependency: `claw-rag-service = { path = "D:/tempo/claw-code/rust/crates/claw-rag-service" }`. Use forward slashes.
+- Must compile with `cargo build --release` and `cargo test --release`. On this machine every cargo invocation needs MSVC: run via `cmd /c "C:\Users\Incredible\.config\opencode\CompilePreSet.bat && cargo ..."`.
+- `#![forbid(unsafe_code)]` applies to every crate compiled (standalone crate sets its own `[lints.rust] unsafe_code = "forbid"`).
+- MCP protocol subset only: `initialize`, `tools/list`, `tools/call`. Protocol version `2025-03-26`. Capabilities `{"tools": {}}`. serverInfo name = `claw-rag`, version = `env!("CARGO_PKG_VERSION")`.
+- Tool names: `rag_query`, `rag_stats`, `rag_ingest`, `rag_ingest_status`. **No coupling with the original `retrieve_context` naming or behavior.**
+- Shared index: env `CLAW_RAG_DB` (default `.claw-rag/index.sqlite`). Embedding env vars: `CLAW_RAG_OPENAI_API_KEY`/`OPENAI_API_KEY`, `CLAW_RAG_EMBEDDING_BASE_URL` (default `https://api.openai.com/v1`), `CLAW_RAG_EMBEDDING_MODEL` (default `text-embedding-3-small`), `CLAW_RAG_MOCK_PROVIDERS=1` for deterministic mock vectors in tests.
+- `rag_query`: `top_k` default 8, clamped 1..=32.
+- JSON-RPC error codes: `-32700` parse, `-32600` invalid request, `-32601` method not found, `-32602` invalid params.
+- Tool-level failures → `isError: true` + text message.
+- Ingest jobs: in-memory registry, serialized through a global async mutex, `job_id` is an incrementing integer string (`"1"`, `"2"`, …). No persistence, no HTTP/SSE, no resources/prompts/auth.
+
+---
+
+### Task 1: claw-rag-service — add progress reporting to ingest
+
+**Files:**
+- Modify: `D:\tempo\claw-code\rust\crates\claw-rag-service\src\ingest.rs:30-207`
+- Modify: `D:\tempo\claw-code\rust\crates\claw-rag-service\src\lib.rs:14`
+
+**Interfaces:**
+- Consumes: existing `IngestStats` (files_indexed, chunks_total, embeddings_written).
+- Produces: `pub struct IngestProgress { pub files_done: usize, pub files_total: usize, pub chunks_total: usize }` and `pub async fn run_ingest_with_progress<F>(workspaces: &[PathBuf], db_path: &Path, cfg: &EmbedConfig, client: &Client, progress: F) -> Result<IngestStats, String> where F: FnMut(IngestProgress)`. `run_ingest` is preserved as a delegating wrapper (zero caller changes).
+
+- [ ] **Step 1: Write the failing test**
+
+Append a `#[cfg(test)] mod tests` at the end of `ingest.rs`:
+
+```rust
+#[cfg(test)]
+mod tests {
+    use super::*;
+    use reqwest::Client;
+    use tempfile::tempdir;
+
+    #[tokio::test]
+    async fn run_ingest_with_progress_reports_all_files() {
+        std::env::set_var("CLAW_RAG_MOCK_PROVIDERS", "1");
+        let dir = tempdir().unwrap();
+        let ws = dir.path().join("ws");
+        std::fs::create_dir_all(&ws).unwrap();
+        std::fs::write(ws.join("a.rs"), "alpha beta").unwrap();
+        std::fs::write(ws.join("b.rs"), "gamma delta").unwrap();
+        let db = dir.path().join("idx.sqlite");
+        let client = Client::new();
+        let cfg = EmbedConfig::mock_from_env().expect("mock embed config");
+        let mut seen = Vec::new();
+        let st = run_ingest_with_progress(&[ws.clone()], &db, &cfg, &client, |p| seen.push(p))
+            .await
+            .expect("ingest");
+        assert_eq!(st.files_indexed, 2);
+        let last = seen.last().expect("progress emitted");
+        assert_eq!(last.files_total, 2);
+        assert_eq!(last.files_done, 2);
+        assert!(last.chunks_total > 0);
+        std::env::remove_var("CLAW_RAG_MOCK_PROVIDERS");
+    }
+}
+```
+
+- [ ] **Step 2: Run test to verify it fails**
+
+Run: `cmd /c "C:\Users\Incredible\.config\opencode\CompilePreSet.bat && cargo test --release -p claw-rag-service run_ingest_with_progress"`
+Expected: FAIL — `cannot find function run_ingest_with_progress`.
+
+- [ ] **Step 3: Implement `IngestProgress` and `run_ingest_with_progress`**
+
+In `ingest.rs`, after the `IngestStats` struct definition (line 35), add:
+
+```rust
+#[derive(Debug, Clone, Copy)]
+pub struct IngestProgress {
+    pub files_done: usize,
+    pub files_total: usize,
+    pub chunks_total: usize,
+}
+```
+
+Replace the entire `run_ingest` function (lines 92-207) with:
+
+```rust
+pub async fn run_ingest(
+    workspaces: &[PathBuf],
+    db_path: &Path,
+    cfg: &EmbedConfig,
+    client: &Client,
+) -> Result<IngestStats, String> {
+    run_ingest_with_progress(workspaces, db_path, cfg, client, |_| {}).await
+}
+
+pub async fn run_ingest_with_progress<F>(
+    workspaces: &[PathBuf],
+    db_path: &Path,
+    cfg: &EmbedConfig,
+    client: &Client,
+    mut progress: F,
+) -> Result<IngestStats, String>
+where
+    F: FnMut(IngestProgress),
+{
+    let conn = open_db(db_path)?;
+
+    let mut all_files: Vec<(String, PathBuf)> = Vec::new();

+
+    for ws in workspaces {

+            let rel = path
+                .strip_prefix(&ws_prefix)
+                .unwrap_or(path)
+                .to_string_lossy()

+        }
+    }
+
+    all_files.sort_by(|a, b| a.0.cmp(&b.0));
+    seen_paths.sort();
+
+    let mut stats = IngestStats {
+        files_indexed: all_files.len(),
+        ..Default::default()
+    };
+
+    for (idx, (rel, file)) in all_files.iter().enumerate() {
+        progress(IngestProgress {
+            files_done: idx + 1,
+            files_total: all_files.len(),

+            .and_then(|d| i64::try_from(d.as_millis()).ok())
+            .unwrap_or(0);
+
+        let Ok(raw) = std::fs::read_to_string(file) else {
+            continue;
+        };
+
+        let content_hash = blake3::hash(raw.as_bytes()).to_hex().to_string();
+        if file_is_unchanged(&conn, rel, &content_hash, size_bytes, mtime_ms)? {
+            continue;
+        }
+
+        // Re-index this file: delete previous chunks (and embeddings) for path.
+        delete_file_and_chunks(&conn, rel)?;
+
+        let pieces = chunk_text(&raw, CHUNK_CHARS, CHUNK_OVERLAP);
+        if pieces.is_empty() {
+            continue;
+        }
+
+        let mut batch: Vec<(i32, String)> = Vec::new();
+        for (ord, piece) in pieces.into_iter().enumerate() {
+            stats.chunks_total += 1;
+            let ord_i32 =
+                i32::try_from(ord).map_err(|_| "file produced too many chunks".to_string())?;
+            batch.push((ord_i32, piece));
+            if batch.len() >= EMBED_BATCH {
+                flush_path_batch(&conn, rel, &mut batch, client, cfg, &mut stats).await?;
+            }
+        }
+        flush_path_batch(&conn, rel, &mut batch, client, cfg, &mut stats).await?;
+
+        let now_ms = std::time::SystemTime::now()
+            .duration_since(std::time::UNIX_EPOCH)
+            .map(|d| i64::try_from(d.as_millis()).unwrap_or(0))
+            .unwrap_or(0);
+        upsert_file_meta(&conn, rel, &content_hash, size_bytes, mtime_ms, now_ms)?;
+    }
+
+    // Delete entries for files that no longer exist.
+    // (We compare against file list from DB to avoid needing a SQL "NOT IN" temp table.)
+    let mut seen_set = std::collections::BTreeSet::new();

+    for p in list_all_files(&conn)? {
+        if !seen_set.contains(p.as_str()) {
+            delete_file_and_chunks(&conn, &p)?;
+        }
+    }
+
+    Ok(stats)
+}
+```
+
+Note: the loop body now borrows `rel`/`file` (`&rel`, `&file`) because `all_files` is iterated by reference; `flush_path_batch` takes `&str` and `&PathBuf` params, so pass `rel` and `file` (auto-deref) as in the code above.
+
+- [ ] **Step 4: Export from lib.rs**
+
+In `D:\tempo\claw-code\rust\crates\claw-rag-service\src\lib.rs`, change line 14:
+
+```rust
+pub use ingest::{run_ingest, run_ingest_with_progress, IngestProgress, IngestStats};
+```
+
+- [ ] **Step 5: Run the new test and the existing ingest roundtrip test**
+
+Run: `cmd /c "C:\Users\Incredible\.config\opencode\CompilePreSet.bat && cargo test --release -p claw-rag-service"`
+Expected: PASS (all tests including `run_ingest_with_progress_reports_all_files` and existing `ingest_and_query_roundtrip_mock`).
+
+- [ ] **Step 6: Commit (in claw-code repo)**
+
+```bash
+cd D:\tempo\claw-code
+git add rust/crates/claw-rag-service/src/ingest.rs rust/crates/claw-rag-service/src/lib.rs
+git commit -m "feat(rag-service): add run_ingest_with_progress with IngestProgress"
+```
+

+
+### Task 2: Scaffold the standalone project
+
+**Files:**
+- Create: `D:\tempo\claw-rag-mcp\Cargo.toml`
+- Create: `D:\tempo\claw-rag-mcp\.gitignore`
+- Create: `D:\tempo\claw-rag-mcp\src\lib.rs`
+- Create: `D:\tempo\claw-rag-mcp\src\main.rs`
+- Create: `D:\tempo\claw-rag-mcp\src\framing.rs`
+- Create: `D:\tempo\claw-rag-mcp\src\protocol.rs`
+- Create: `D:\tempo\claw-rag-mcp\src\server.rs`
+- Create: `D:\tempo\claw-rag-mcp\src\tools.rs`
+
+**Interfaces:**
+- Consumes: `claw-rag-service` lib from Task 1.
+- Produces: compilable crate skeleton with module stubs. Later tasks fill each module.
+
+- [ ] **Step 1: Create the directory and Cargo.toml**
+
+Create `D:\tempo\claw-rag-mcp\Cargo.toml`:
+
+```toml
+[package]
+name = "claw-rag-mcp"
+version = "0.1.0"
+edition = "2021"
+license = "MIT"
+description = "Standalone MCP server exposing RAG query/stats/ingest over a shared SQLite index"
+
+[workspace]
+
+[dependencies]
+claw-rag-service = { path = "D:/tempo/claw-code/rust/crates/claw-rag-service" }
+reqwest = { version = "0.12", default-features = false, features = ["json", "rustls-tls"] }
+serde = { version = "1", features = ["derive"] }
+serde_json = "1"
+tokio = { version = "1", features = ["macros", "rt-multi-thread", "io-std", "io-util", "sync", "time"] }
+
+[dev-dependencies]
+tempfile = "3"
+
+[lints.rust]
+unsafe_code = "forbid"
+```
+
+Create `D:\tempo\claw-rag-mcp\.gitignore`:
+
+```
+/target
+```
+
+- [ ] **Step 2: Create module stubs**
+
+Create `D:\tempo\claw-rag-mcp\src\framing.rs`:
+
+```rust
+//! LSP `Content-Length` framing for MCP stdio transport.
+```
+
+Create `D:\tempo\claw-rag-mcp\src\protocol.rs`:
+
+```rust
+//! JSON-RPC 2.0 and MCP message types.
+```
+
+Create `D:\tempo\claw-rag-mcp\src\server.rs`:
+
+```rust
+//! Minimal stdio MCP server: dispatch over LSP-framed JSON-RPC.
+```
+
+Create `D:\tempo\claw-rag-mcp\src\tools.rs`:
+
+```rust
+//! RAG tool handlers and the async ingest job registry.
+```
+
+Create `D:\tempo\claw-rag-mcp\src\lib.rs`:
+
+```rust
+//! Standalone RAG MCP server (stdio).
+#![forbid(unsafe_code)]
+
+pub mod framing;
+pub mod protocol;
+pub mod server;
+pub mod tools;
+```
+
+Create `D:\tempo\claw-rag-mcp\src\main.rs`:
+
+```rust
+use std::sync::Arc;
+
+use claw_rag_mcp::tools::{build_server, AppState};
+
+#[tokio::main]
+async fn main() -> Result<(), Box<dyn std::error::Error + Send + Sync>> {
+    let state = Arc::new(AppState::from_env()?);
+    let server = build_server(state);
+    server.run(tokio::io::stdin(), tokio::io::stdout()).await?;
+    Ok(())
+}
+```
+
+(These reference `AppState`, `build_server`, and `McpServer::run` which Tasks 4-6 implement; the crate will not compile until then — that is expected and resolved in Task 6.)
+
+- [ ] **Step 3: git init and verify the crate starts building**
+
+Run:
+```bash
+cd D:\tempo\claw-rag-mcp
+git init
+git add -A
+git commit -m "chore: scaffold claw-rag-mcp crate"
+cmd /c "C:\Users\Incredible\.config\opencode\CompilePreSet.bat && cargo build --release"
+```
+Expected: build fails with "cannot find function `build_server`" — confirming the path dependency on `claw-rag-service` resolves (its deps, incl. bundled rusqlite, compile successfully). If it fails earlier on `claw-rag-service`, the path in `Cargo.toml` is wrong.
+
+- [ ] **Step 4: Commit scaffold**
+
+```bash
+git add -A
+git commit -m "chore: verify claw-rag-service path dependency compiles"
+```
+(Only run after confirming the dependency resolved; if the crate compiles fully, fine — commit either way.)
+
+---
+
+### Task 3: protocol module — JSON-RPC and MCP types + framing
+
+**Files:**
+- Modify: `D:\tempo\claw-rag-mcp\src\protocol.rs`
+- Modify: `D:\tempo\claw-rag-mcp\src\framing.rs`
+
+**Interfaces:**
+- Consumes: serde, serde_json.
+- Produces: `JsonRpcId` (untagged enum Null/Number/String), `JsonRpcRequest<T>`, `JsonRpcResponse<T>`, `JsonRpcError`, `McpTool`, `McpInitializeResult`, `McpServerInfo`, `McpListToolsResult`, `McpToolCallParams`, `McpToolCallResult`, `McpToolCallContent`, `PROTOCOL_VERSION: &str = "2025-03-26"`. Plus `framing::read_frame<R: AsyncBufRead + Unpin>(&mut R) -> io::Result<Option<Vec<u8>>>` and `framing::write_frame<W: AsyncWrite + Unpin>(&mut W, &[u8]) -> io::Result<()>`.
+

+Note: `rag_ingest` is a stub here; Task 6 replaces it. `rag_ingest_status` already reads the (currently always-empty) registry, which is fine for these tests.

+- [ ] **Step 4: Run tests to verify they pass**
+
+Run: `cmd /c "C:\Users\Incredible\.config\opencode\CompilePreSet.bat && cargo test --release -p claw-rag-mcp --lib tools::tests"`
+Expected: PASS (5 tests). The `rag_ingest` stub returns an error — no test calls it yet.

+### Task 6: tools module — async ingest job
+
+**Files:**
+- Modify: `D:\tempo\claw-rag-mcp\src\tools.rs`
+
+**Interfaces:**
+- Consumes: `AppState`, `JobStatus`, `JobState`, `handle_tool` dispatch from Task 5; claw-rag-service `run_ingest_with_progress`, `IngestProgress` from Task 1.
+- Produces: working `rag_ingest` (spawns background task, returns `job_id: N`) and working `rag_ingest_status` (progress).
+
+- [ ] **Step 1: Write the failing test**
+
+Append to the `tests` module in `tools.rs`:
+
+```rust
+#[tokio::test]
+async fn ingest_job_lifecycle_with_mock_embeddings() {
+    std::env::set_var("CLAW_RAG_MOCK_PROVIDERS", "1");

+- [ ] **Step 2: Run test to verify it fails**
+
+Run: `cmd /c "C:\Users\Incredible\.config\opencode\CompilePreSet.bat && cargo test --release -p claw-rag-mcp --lib tools::tests::ingest_job_lifecycle_with_mock_embeddings"`
+Expected: FAIL — `rag_ingest` returns "not yet implemented".
+
+- [ ] **Step 3: Implement rag_ingest**
+
+Replace the `rag_ingest` stub in `tools.rs` with:

+
+### Task 8: README and final verification
+
+**Files:**
+- Create: `D:\tempo\claw-rag-mcp\README.md`
+
+**Interfaces:**
+- Consumes: everything above.
+- Produces: installation/usage documentation.
+
+- [ ] **Step 1: Write README.md**
+
+Create `D:\tempo\claw-rag-mcp\README.md`:
+
+```markdown
+# claw-rag-mcp
+
+Standalone MCP (Model Context Protocol) server exposing RAG capabilities over a
+SQLite index shared with `claw-rag-service`.
+
+## Install
+
+```bash
+cd D:\tempo\claw-rag-mcp
+cargo build --release
+```
+
+Copy `target\release\claw-rag-mcp.exe` to a directory on your PATH
+(e.g. `C:\Users\<you>\bin`).
+
+## Configure an MCP host
+
+Point any MCP client at the binary via `command`. Example for opencode:
+
+```json
+{
+  "mcpServers": {
+    "claw-rag": {
+      "command": "claw-rag-mcp",
+      "env": {
+        "CLAW_RAG_DB": "D:/data/rag/.claw-rag/index.sqlite",
+        "OPENAI_API_KEY": "sk-..."
+      }
+    }
+  }
+}
+```
+
+## Environment variables
+
+| Variable | Default | Purpose |
+|---|---|---|
+| `CLAW_RAG_DB` | `.claw-rag/index.sqlite` | Shared SQLite index path |
+| `CLAW_RAG_OPENAI_API_KEY` / `OPENAI_API_KEY` | — | Embedding API key (required) |
+| `CLAW_RAG_EMBEDDING_BASE_URL` | `https://api.openai.com/v1` | OpenAI-compatible embeddings endpoint |
+| `CLAW_RAG_EMBEDDING_MODEL` | `text-embedding-3-small` | Embedding model |
+| `CLAW_RAG_MOCK_PROVIDERS` | — | `1` = deterministic mock embeddings (testing) |
+
+## Tools
+
+- `rag_query {query, top_k?}` — semantic search over the index. `top_k` default 8, max 32.
+- `rag_stats {}` — chunk count and index phase (`1-sqlite-no-db` / `1-sqlite-empty` / `1-sqlite`).
+- `rag_ingest {workspaces: [...]}` — asynchronously index workspaces; returns a `job_id`.
+- `rag_ingest_status {job_id}` — poll ingest progress (`running` / `done` / `failed` / `unknown`).
+
+## Notes
+
+- Ingest jobs live in process memory; restarting the server loses them. Re-run
+  `rag_ingest` after a restart.
+- The index is shared with the `claw-rag-service` HTTP server when both use the
+  same `CLAW_RAG_DB`. Only one process should ingest at a time (ingest jobs are
+  serialized within this server).
+```
+
+- [ ] **Step 2: Final verification**
+
+Run:
+```bash
+cmd /c "C:\Users\Incredible\.config\opencode\CompilePreSet.bat && cargo fmt -- --check"
+cmd /c "C:\Users\Incredible\.config\opencode\CompilePreSet.bat && cargo clippy --release --all-targets -- -D warnings"
+cmd /c "C:\Users\Incredible\.config\opencode\CompilePreSet.bat && cargo test --release"
+```
+Expected: fmt clean, clippy clean, all tests PASS.
+
+- [ ] **Step 3: Smoke-test the binary over real pipes**
+
+In PowerShell (uses a temp DB, mock embeddings):
+```powershell
+$env:CLAW_RAG_MOCK_PROVIDERS = "1"
+$db = Join-Path $env:TEMP "claw-rag-mcp-smoke.sqlite"
+Remove-Item $db -ErrorAction SilentlyContinue
+$env:CLAW_RAG_DB = $db
+$body = '{"jsonrpc":"2.0","id":1,"method":"initialize","params":{}}'
+$frame = "Content-Length: $($body.Length)`r`n`r`n$body"
+$frame | & .\target\release\claw-rag-mcp.exe
+Remove-Item Env:\CLAW_RAG_MOCK_PROVIDERS
+Remove-Item Env:\CLAW_RAG_DB
+```
+Expected: prints a `Content-Length`-framed `initialize` response with `"serverInfo":{"name":"claw-rag"}` and exits when stdin closes.
+
+- [ ] **Step 4: Commit**
+
+```bash
+git add README.md
+git commit -m "docs: installation and usage for claw-rag-mcp"
+```

+# claw-rag-mcp — 独立 RAG MCP Server 设计
+
+日期：2026-08-13
+状态：已批准（设计评审通过）
+
+## 背景与目标
+
+将 `claw-rag-service` 的 RAG 能力（语义检索 / 索引 / 统计）封装为一个**完全独立**的 MCP server 可执行文件，放入系统 PATH，供任意 MCP host（opencode、Claude Desktop、Cursor 等）通过标准 `command` 方式启动，走 stdio 传输协议。
+
+**关键约束**：
+- **与 claw-analog / 原 HTTP 服务的 `retrieve_context` 实现无任何耦合**。工具名、实现、行为均为全新设计，不沿用原版的工具名（`retrieve_context`）与调用约定。
+- 独立可分发 exe（`cargo build --release` 后单文件），放 PATH 即用。
+- 传输层自研极简 stdio（参考 `runtime::mcp_server.rs` 的 framing/dispatch 模式），**零外部协议依赖**，符合仓库 `forbid(unsafe_code)` lint。
+- 依赖 `claw-rag-service` 的 lib（`query_index` / `run_ingest` / `chunk_count` / `EmbedConfig`）复用索引、分块、embedding 逻辑；与现有 HTTP 服务**共享同一份 SQLite 索引**（`CLAW_RAG_DB`，默认 `.claw-rag/index.sqlite`）。

+
+注意：位置决策已更新（用户确认）——**独立文件夹 `D:\tempo\claw-rag-mcp`**，path 依赖指向 claw-code 仓库的 rag-service，二者各自独立构建，不共享 workspace 依赖解析（`serde_json` 需在独立 Cargo.toml 中显式声明，不能引用 `workspace = true`）。
+
+- 二进制名：`claw-rag-mcp`
+- 协议版本：`2025-03-26`
+- 能力声明：`{"tools": {}}`
+- 配置环境变量（复用 claw-rag-service 现有约定）：
+  - `CLAW_RAG_DB`：SQLite 索引路径（默认 `.claw-rag/index.sqlite`）
+  - `CLAW_RAG_OPENAI_API_KEY` / `OPENAI_API_KEY`：embedding API key
+  - `CLAW_RAG_EMBEDDING_BASE_URL`：默认 `https://api.openai.com/v1`
+  - `CLAW_RAG_EMBEDDING_MODEL`：默认 `text-embedding-3-small`
+  - `CLAW_RAG_MOCK_PROVIDERS=1`：确定性 mock embedding（测试/试用）
+
+## 暴露的工具（全新命名，前缀 `rag_`）
+
+| 工具 | 入参 | 返回 | 权限 |
+|---|---|---|---|
+| `rag_query` | `query`(必填), `top_k`(默认8, ≤32) | 格式化 hits（path/snippet/score）+ `phase` | 只读 |
+| `rag_stats` | `{}` | `chunks` 数 + `phase` | 只读 |
+| `rag_ingest` | `workspaces`: 路径数组 | 立即返回 `job_id`（后台任务） | 写索引 |
+| `rag_ingest_status` | `job_id` | `running`(进度) / `done`(统计) / `failed`(错误) / `unknown` | 只读 |
+
+`phase` 取值（沿用索引状态语义，但作为输出字段而非协议）：
+- `1-sqlite-no-db`：索引文件不存在
+- `1-sqlite-empty`：索引存在但无 chunk
+- `1-sqlite`：有数据
+
+## 异步 ingest job 机制
+
+- 进程内存 `JobRegistry`（`Mutex<HashMap<job_id, JobState>>`）。stdio server 为长驻进程，job 跨 `tools/call` 有效。
+- **限制**：host 重启进程后 job 丢失（不持久化）。在文档中注明；符合"查询 + 维护性索引"定位。
+- **进度上报**：给 `claw-rag-service` 增加 `run_ingest_with_progress(workspaces, db_path, cfg, client, progress: impl FnMut(IngestProgress))`；现有 `run_ingest` 委托它并传 no-op。`IngestProgress { files_done, files_total, chunks_total }`。现有调用方零改动。
+- **SQLite 单写者约束**：ingest job 用全局 `Mutex` 串行执行，避免 SQLITE_BUSY。
+- job_id：进程内递增整数转字符串（如 `"1"`、`"2"`）。
+
+## 错误处理
+
+- JSON-RPC 规范错误码：
+  - `-32700` parse error
+  - `-32600` invalid request
+  - `-32601` method not found
+  - `-32602` invalid params
+- 工具执行错误 → `isError: true` + text 消息（与 claw 现有约定一致），例如：
+  - `no index (run rag_ingest first)`
+  - `embedding dimension mismatch ...`（索引维度与查询维度不一致提示）
+  - 工具参数缺失/非法
+
+## 测试
+
+- **单元**：dispatch 层各分支（initialize / tools/list / tools/call 正常与错误 / 未知方法 / 非法参数）。
+- **集成**：`CLAW_RAG_MOCK_PROVIDERS=1` + tempdir，全流程：
+  1. `rag_ingest` 起 job → 立即返回 job_id
+  2. 轮询 `rag_ingest_status` 至 `done`
+  3. `rag_query` 命中相关文件
+  4. `rag_stats` 反映 chunks 数
+- **framing**：进程内 pipe 模拟 stdin/stdout 往返验证 LSP 帧格式与 dispatch。
+
+## 非目标（YAGNI）
+
+- 不做 HTTP/SSE 传输。
+- 不持久化 job 状态。
+- 不实现 MCP resources / prompts / 认证。
+- 不改动 claw-analog 的 `retrieve_context` 实现。
+- 不新增对 `runtime` crate 的依赖（避免引入 plugins/telemetry）。
+- 不把项目放入 claw-code 仓库（独立文件夹，独立版本号）。
+
+## 文档
+
+- 在 `rust/README` 或 crate 内 `README.md` 记录安装与配置方式：
+  - `cargo build --release -p claw-rag-mcp` → 将 `target/release/claw-rag-mcp.exe` 放入 PATH
+  - opencode / Claude Desktop 配置 `command: "claw-rag-mcp"`
+  - 环境变量说明

directly.\\n\\n## Workspace layout\\n\\n```text\\nrust/\\n├── Cargo.toml\\n├── Cargo.lock\\n├── README.md\\n└── crates/\\n    ├── api/               # Anthropic API client + SSE streaming support\\n    ├── commands/          # Shared slash-command metadata/help surfaces\\n    ├── compat-harness/    # Upstream TS manifest extraction harness\\n    ├── runtime/           # Session/runtime/config/prompt orchestration\\n    ├── rusty-claude-cli/  # Main CLI binary\\n    └── tools/             # Built-in tool implementations\\n```\\n\\n## Prerequisites\\n\\n- Rust toolchain installed (`rustup`, stable toolchain)\\n- Network access and Anthropic credentials for live prompt/REPL usage\\n\\n## Build\\n\\nFrom the repository root:\\n\\n```bash\\ncd rust\\ncargo build --release -p rusty-claude-cli\\n```\\n\\nThe optimized binary will be written to:\\n\\n```bash\\n./target/release/rusty-claude-cli\\n```\\n\\n## Test\\n\\nRun the verified workspace test suite used for release-readiness:\\n\\n```bash\\ncd rust\\ncargo test --workspace --exclude compat-harness\\n```\\n\\n## Quick start\\n\\n### Show help\\n\\n```bash\\ncd rust\\ncargo run -p rusty-claude-cli -- --help\\n```\\n\\n### Print version\\n\\n```bash\\ncd rust\\ncargo run -p rusty-claude-cli -- --version\\n```\\n\\n### Login with OAuth\\n\\nConfigure `settings.json` with an `oauth` block containing `clientId`, `authorizeUrl`, `tokenUrl`, optional `callbackPort`, and optional `scopes`, then run:\\n\\n```bash\\ncd rust\\ncargo run -p rusty-claude-cli -- login\\n```\\n\\nThis opens the browser, listens on the configured localhost callback, exchanges the auth code for tokens, and stores OAuth credentials in `~/.claude/credentials.json` (or `$CLAUDE_CONFIG_HOME/credentials.json`).\\n\\n### Logout\\n\\n```bash\\ncd rust\\ncargo run -p rusty-claude-cli -- logout\\n```\\n\\nThis removes only the stored OAuth credentials and preserves unrelated JSON fields in `credentials.json`.\\n\\n### Self-update\\n\\n```bash\\ncd rust\\ncargo run -p rusty-claude-cli -- self-update\\n```\\n\\nThe command checks the latest GitHub release for `instructkr/clawd-code`, compares it to the current binary version, downloads the matching binary asset plus checksum manifest, verifies SHA-256, replaces the current executable, and prints the release changelog. If no published release or matching asset exists, it exits safely with an explanatory message.\\n\\n## Usage examples\\n\\n### 1) Prompt mode\\n\\nSend one prompt, stream the answer, then exit:\\n\\n```bash\\ncd rust\\ncargo run -p rusty-claude-cli -- prompt \\\"Summarize the architecture of this repository\\\"\\n```\\n\\nUse a specific model:\\n\\n```bash\\ncd rust\\ncargo run -p rusty-claude-cli -- --model claude-sonnet-4-20250514 prompt \\\"List the key crates in this workspace\\\"\\n```\\n\\nRestrict enabled tools in an interactive session:\\n\\n```bash\\ncd rust\\ncargo run -p rusty-claude-cli -- --allowedTools read,glob\\n```\\n\\nBootstrap Claude project files for the current repo:\\n\\n```bash\\ncd rust\\ncargo run -p rusty-claude-cli -- init\\n```\\n\\n### 2) REPL mode\\n\\nStart the interactive shell:\\n\\n```bash\\ncd rust\\ncargo run -p rusty-claude-cli --\\n```\\n\\nInside the REPL, useful commands include:\\n\\n```text\\n/help\\n/status\\n/model claude-sonnet-4-20250514\\n/permissions workspace-write\\n/cost\\n/compact\\n/memory\\n/config\\n/init\\n/diff\\n/version\\n/export notes.txt\\n/sessions\\n/session list\\n/exit\\n```\\n\\n### 3) Resume an existing session\\n\\nInspect or maintain a saved session file without entering the REPL:\\n\\n```bash\\ncd rust\\ncargo run -p rusty-claude-cli -- --resume session-123456 /status /compact /cost\\n```\\n\\nYou can also inspect memory/config state for a restored session:\\n\\n```bash\\ncd rust\\ncargo run -p rusty-claude-cli -- --resume ~/.claude/sessions/session-123456.json /memory /config\\n```\\n\\n## Available commands\\n\\n### Top-level CLI commands\\n\\n- `prompt <text...>` — run one prompt non-interactively\\n- `--resume <session-id-or-path> [/commands...]` — inspect or maintain a saved session stored under `~/.claude/sessions/`\\n- `dump-manifests` — print extracted upstream manifest counts\\n- `bootstrap-plan` — print the current bootstrap skeleton\\n- `system-prompt [--cwd PATH] [--date YYYY-MM-DD]` — render the synthesized system prompt\\n- `self-update` — update the installed binary from the latest GitHub release when a matching asset is available\\n- `--help` / `-h` — show CLI help\\n- `--version` / `-V` — print the CLI version and build info locally (no API call)\\n- `--output-format text|json` — choose non-interactive prompt output rendering\\n- `--allowedTools <tool[,tool...]>` — restrict enabled tools for interactive sessions and prompt-mode tool use\\n\\n### Interactive slash commands\\n\\n- `/help` — show command help\\n- `/status` — show current session status\\n- `/compact` — compact local session history\\n- `/model [model]` — inspect or switch the active model\\n- `/permissions [read-only|workspace-write|danger-full-access]` — inspect or switch permissions\\n- `/clear [--confirm]` — clear the current local session\\n- `/cost` — show token usage totals\\n- `/resume <session-id-or-path>` — load a saved session into the REPL\\n- `/config [env|hooks|model]` — inspect discovered Claude config\\n- `/memory` — inspect loaded instruction memory files\\n- `/init` — bootstrap `.claude.json`, `.claude/`, `CLAUDE.md`, and local ignore rules\\n- `/diff` — show the current git diff for the workspace\\n- `/version` — print version and build metadata locally\\n- `/export [file]` — export the current conversation transcript\\n- `/sessions` — list recent managed local sessions from `~/.claude/sessions/`\\n- `/session [list|switch <session-id>]` — inspect or switch managed local sessions\\n- `/exit` — leave the REPL\\n\\n## Environment variables\\n\\n### Anthropic/API\\n\\n- `ANTHROPIC_API_KEY` — highest-precedence API credential\\n- `ANTHROPIC_AUTH_TOKEN` — bearer-token override used when no API key is set\\n- Persisted OAuth credentials in `~/.claude/credentials.json` — used when neither env var is set\\n- `ANTHROPIC_BASE_URL` — override the Anthropic API base URL\\n- `ANTHROPIC_MODEL` — default model used by selected live integration tests\\n\\n### CLI/runtime\\n\\n- `RUSTY_CLAUDE_PERMISSION_MODE` — default REPL permission mode (`read-only`, `workspace-write`, or `danger-full-access`)\\n- `CLAUDE_CONFIG_HOME` — override Claude config discovery root\\n- `CLAUDE_CODE_REMOTE` — enable remote-session bootstrap handling when supported\\n- `CLAUDE_CODE_REMOTE_SESSION_ID` — remote session identifier when using remote mode\\n- `CLAUDE_CODE_UPSTREAM` — override the upstream TS source path for compat-harness extraction\\n- `CLAWD_WEB_SEARCH_BASE_URL` — override the built-in web search service endpoint used by tooling\\n\\n## Notes\\n\\n- `compat-harness` exists to compare the Rust port against the upstream TypeScript codebase and is intentionally excluded from the requested release test run.\\n- The CLI currently focuses on a practical integrated workflow: prompt execution, REPL operation, session inspection/resume, config discovery, and tool/runtime plumbing.\\n\",\n  \"stderr\": \"\",\n  \"rawOutputPath\": null,\n  \"interrupted\": false,\n  \"isImage\": null,\n  \"backgroundTaskId\": null,\n

Enhancement Plan\\n\\n### Phase 0: Structural Cleanup (Foundation)\\n\\n**Goal**: Break the monolith, remove dead code, establish the module structure for TUI work.\\n\\n| Task | Description | Effort |\\n|---|---|---|\\n| 0.1 | **Extract `LiveCli` into `app.rs`** — Move the entire `LiveCli` struct, its impl, and helpers (`format_*`, `render_*`, session management) out of `main.rs` into focused modules: `app.rs` (core), `format.rs` (report formatting), `session_manager.rs` (session CRUD) | M |\\n| 0.2 | **Remove or merge the legacy `CliApp`** — The existing `app.rs` has an unused `CliApp` with its own `ConversationClient`-based rendering. Either delete it or merge its unique features (stream event handler pattern) into the active `LiveCli` | S |\\n| 0.3 | **Extract `main.rs` arg parsing** — The current `parse_args()` is a hand-rolled parser that duplicates the clap-based `args.rs`. Consolidate on the hand-rolled parser (it's more feature-complete) and move it to `args.rs`, or adopt clap fully | S |\\n| 0.4 | **Create a `tui/` module** — Introduce `crates/rusty-claude-cli/src/tui/mod.rs` as the namespace for all new TUI components: `status_bar.rs`, `layout.rs`, `tool_panel.rs`, etc. | S |\\n\\n### Phase 1: Status Bar & Live HUD\\n\\n**Goal**: Persistent information display during interaction.\\n\\n| Task | Description | Effort |\\n|---|---|---|\\n| 1.1 | **Terminal-size-aware status line** — Use `crossterm::terminal::size()` to render a bottom-pinned status bar showing: model name, permission mode, session ID, cumulative token count, estimated cost | M |\\n| 1.2 | **Live token counter** — Update the status bar in real-time as `AssistantEvent::Usage` and `AssistantEvent::TextDelta` events arrive during streaming | M |\\n| 1.3 | **Turn duration timer** — Show elapsed time for the current turn (the `showTurnDuration` config already exists in Config tool but isn't wired up) | S |\\n| 1.4 | **Git branch indicator** — Display the current git branch in the status bar (already parsed via `parse_git_status_metadata`) | S |\\n\\n### Phase 2: Enhanced Streaming Output\\n\\n**Goal**: Make the main response stream visually rich and responsive.\\n\\n| Task | Description | Effort |\\n|---|---|---|\\n| 2.1 | **Live markdown rendering** — Instead of raw text streaming, buffer text deltas and incrementally render Markdown as it arrives (heading detection, bold/italic, inline code). The existing `TerminalRenderer::render_markdown` can be adapted for incremental use | L |\\n| 2.2 | **Thinking indicator** — When extended thinking/reasoning is active, show a distinct animated indicator (e.g., `🧠 Reasoning...` with pulsing dots or a different spinner) instead of the generic `🦀 Thinking...` | S |\\n| 2.3 | **Streaming progress bar** — Add an optional horizontal progress indicator below the spinner showing approximate completion (based on max_tokens vs. output_tokens so far) | M |\\n| 2.4 | **Remove artificial stream delay** — The current `stream_markdown` sleeps 8ms per chunk. For tool results this is fine, but for the main response stream it should be immediate or configurable | S |\\n\\n### Phase 3: Tool Call Visualization\\n\\n**Goal**: Make tool execution legible and navigable.\\n\\n| Task | Description | Effort |\\n|---|---|---|\\n| 3.1 | **Collapsible tool output** — For tool results longer than N lines (configurable, default 15), show a summary with `[+] Expand` hint; pressing a key reveals the full output. Initially implement as truncation with a \\\"full output saved to file\\\" fallback | M |\\n| 3.2 | **Syntax-highlighted tool results** — When tool results contain code (detected by tool name — `bash` stdout, `read_file` content, `REPL` output), apply syntect highlighting rather than rendering as plain text | M |\\n| 3.3 | **Tool call timeline** — For multi-tool turns, show a compact summary: `🔧 bash → ✓ | read_file → ✓ | edit_file → ✓ (3 tools, 1.2s)` after all tool calls complete | S |\\n| 3.4 | **Diff-aware edit_file display** — When `edit_file` succeeds, show a colored unified diff of the change instead of just `✓ edit_file: path` | M |\\n| 3.5 | **Permission prompt enhancement** — Style the approval prompt with box drawing, color the tool name, show a one-line summary of what the tool will do | S |\\n\\n### Phase 4: Enhanced Slash Commands & Navigation\\n\\n**Goal**: Improve information display and add missing features.\\n\\n| Task | Description | Effort |\\n|---|---|---|\\n| 4.1 | **Colored `/diff` output** — Parse the git diff and render it with red/green coloring for removals/additions, similar to `delta` or `diff-so-fancy` | M |\\n| 4.2 | **Pager for long outputs** — When `/status`, `/config`, `/memory`, or `/diff` produce output longer than the terminal height, pipe through an internal pager (scroll with j/k/q) or external `$PAGER` | M |\\n| 4.3 | **`/search` command** — Add a new command to search conversation history by keyword | M |\\n| 4.4 | **`/undo` command** — Undo the last file edit by restoring from the `originalFile` data in `write_file`/`edit_file` tool results | M |\\n| 4.5 | **Interactive session picker** — Replace the text-based `/session list` with an interactive fuzzy-filterable list (up/down arrows to select, enter to switch) | L |\\n| 4.6 | **Tab completion for tool arguments** — Extend `SlashCommandHelper` to complete file paths after `/export`, model names after `/model`, session IDs after `/session switch` | M |\\n\\n### Phase 5: Color Themes & Configuration\\n\\n**Goal**: User-customizable visual appearance.\\n\\n| Task | Description | Effort |\\n|---|---|---|\\n| 5.1 | **Named color themes** — Add `dark` (current default), `light`, `solarized`, `catppuccin` themes. Wire to the existing `Config` tool's `theme` setting | M |\\n| 5.2 | **ANSI-256 / truecolor detection** — Detect terminal capabilities and fall back gracefully (no colors → 16 colors → 256 → truecolor) | M |\\n| 5.3 | **Configurable spinner style** — Allow choosing between braille dots, bar, moon phases, etc. | S |\\n| 5.4 | **Banner customization** — Make the ASCII art banner optional or configurable via settings | S |\\n\\n### Phase 6: Full-Screen TUI Mode (Stretch)\\n\\n**Goal**: Optional alternate-screen layout for power users.\\n\\n| Task | Description | Effort |\\n|---|---|---|\\n| 6.1 | **Add `ratatui` dependency** — Introduce `ratatui` (terminal UI framework) as an optional dependency for the full-screen mode | S |\\n| 6.2 | **Split-pane layout** — Top pane: conversation with scrollback; Bottom pane: input area; Right sidebar (optional): tool status/todo list | XL |\\n| 6.3 | **Scrollable conversation view** — Navigate past messages with PgUp/PgDn, search within conversation | L |\\n| 6.4 | **Keyboard shortcuts panel** — Show `?` help overlay with all keybindings | M |\\n| 6.5 | **Mouse support** — Click to expand tool results, scroll conversation, select text for copy | L |\\n\\n---\\n\\n## 3. Priority Recommendation\\n\\n### Immediate (High Impact, Moderate Effort)\\n\\n1. **Phase 0** — Essential cleanup. The 3,159-line `main.rs` is the #1 maintenance risk and blocks clean TUI additions.\\n2. **Phase 1.1–1.2** — Status bar with live tokens. Highest-impact UX win: users constantly want to know token usage.\\n3. **Phase 2.4** — Remove artificial delay. Low effort, immediately noticeable improvement.\\n4. **Phase 3.1** — Collapsible tool output. Large bash outputs currently wreck readability.\\n\\n### Near-Term (Next Sprint)\\n\\n5. **Phase 2.1** — Live markdown rendering. Makes the core interaction feel polished.\\n6. **Phase 3.2** — Syntax-highlighted tool results.\\n7. **Phase 3.4** — Diff-aware edit display.\\n8. **Phase 4.1** — Colored diff for `/diff`.\\n\\n### Longer-Term\\n\\n9. **Phase 5** — Color themes (user demand-driven).\\n10. **Phase 4.2–4.6** — Enhanced navigation and commands.\\n11. **Phase 6** — Full-screen mode (major undertaking, evaluate after earlier phases ship).\\n\\n---\\n\\n## 4.

Risk Assessment\\n\\n| Risk | Mitigation |\\n|---|---|\\n| Breaking the working REPL during refactor | Phase 0 is pure restructuring with existing test coverage as safety net |\\n| Terminal compatibility issues (tmux, SSH, Windows) | Rely on crossterm's abstraction; test in degraded environments |\\n| Performance regression with rich rendering | Profile before/after; keep the fast path (raw streaming) always available |\\n| Scope creep into Phase 6 | Ship Phases 0–3 as a coherent release before starting Phase 6 |\\n| `app.rs` vs `main.rs` confusion | Phase 0.2 explicitly resolves this by removing the legacy `CliApp` |\\n\\n---\\n\\n*Generated: 2026-03-31 | Workspace: `rust/` | Branch: `dev/rust`*\\n\"}","name":"write_file","type":"tool_use"}],"role":"assistant","usage":{"cache_creation_input_tokens":0,"cache_read_input_tokens":0,"input_tokens":122226,"output_tokens":4182}},{"blocks":[{"is_error":false,"output":"{\n  \"type\": \"create\",\n  \"filePath\": \"/home/bellman/Workspace/clawd-code/rust/.omc/plans/tui-enhancement-plan.md\",\n  \"content\": \"# TUI Enhancement Plan — Claw Code (`rusty-claude-cli`)\\n\\n## Executive Summary\\n\\nThis plan covers a comprehensive analysis of the current terminal user interface and proposes phased enhancements that will transform the existing REPL/prompt CLI into a polished, modern TUI experience — while preserving the existing clean architecture and test coverage.\\n\\n---\\n\\n## 1.

Architecture Recommendations\\n\\n### Module Structure After Phase 0\\n\\n```\\ncrates/rusty-claude-cli/src/\\n├── main.rs              # Entrypoint, arg dispatch only (~100 lines)\\n├── args.rs              # CLI argument parsing (consolidate existing two parsers)\\n├── app.rs               # LiveCli struct, REPL loop, turn execution\\n├── format.rs            # All report formatting (status, cost, model, permissions, etc.)\\n├── session_mgr.rs       # Session CRUD: create, resume, list, switch, persist\\n├── init.rs              # Repo initialization (unchanged)\\n├── input.rs             # Line editor (unchanged, minor extensions)\\n├── render.rs            # TerminalRenderer, Spinner (extended)\\n└── tui/\\n    ├── mod.rs           # TUI module root\\n    ├── status_bar.rs    # Persistent bottom status line\\n    ├── tool_panel.rs    # Tool call visualization (boxes, timelines, collapsible)\\n    ├── diff_view.rs     # Colored diff rendering\\n    ├── pager.rs         # Internal pager for long outputs\\n    └── theme.rs         # Color theme definitions and selection\\n```\\n\\n### Key Design Principles\\n\\n1. **Keep the inline REPL as the default** — Full-screen TUI should be opt-in (`--tui` flag)\\n2. **Everything testable without a terminal** — All formatting functions take `&mut impl Write`, never assume stdout directly\\n3. **Streaming-first** — Rendering should work incrementally, not buffering the entire response\\n4. **Respect `crossterm` for all terminal control** — Don't mix raw ANSI escape codes with crossterm (the current codebase does this in the startup banner)\\n5. **Feature-gate heavy dependencies** — `ratatui` should be behind a `full-tui` feature flag\\n\\n---\\n\\n## 5.

Here's what I found:\n\n### What's Working Well\n- **Solid rendering pipeline** — `render.rs` has a proper Markdown→terminal renderer with syntax highlighting via syntect, table rendering, lists, blockquotes, and code fences\n- **Rich tool call display** — Box-drawing borders (`╭─ bash ─╮`), ✓/✗ result icons, smart payload summarization per tool type\n- **15 slash commands** — Model switching, permissions, sessions, config, diff, export, compaction — all tested\n- **Full session lifecycle** — Create, persist, list, resume, switch, compact, export, clear\n\n### The Big Problems\n1. **`main.rs` is 3,159 lines** — Everything (REPL loop, API bridge, streaming, formatting, session management, all tests) is in one file. This is the #1 blocker for TUI work.\n2. **`app.rs` has a dead `CliApp`** — An earlier prototype that duplicates `LiveCli` and is never used by the actual entrypoint\n3. **No live status information** — During streaming you see only a braille spinner; no token counts, no elapsed time, no model indicator\n4. **Plain-text streaming** — The assistant response arrives as raw unformatted text; Markdown rendering only kicks in for tool results\n5. **Artificial 8ms delay** in `stream_markdown` — makes tool result display feel sluggish\n6. **No output truncation** — Large bash outputs flood the entire terminal\n\n### The Plan (6 Phases)\n\n| Phase | What | Key Wins | Effort |\n|---|---|---|---|\n| **0: Cleanup** | Split `main.rs` into modules, kill dead `CliApp`, create `tui/` namespace | Unblocks everything; reduces cognitive load | Medium |\n| **1: Status Bar** | Bottom-pinned HUD with model, tokens, cost, git branch, turn timer | Highest UX impact — users always want this info | Medium |\n| **2: Streaming** | Live Markdown rendering, thinking indicator, remove artificial delay | Makes core interaction feel polished | Medium-Large |\n| **3: Tool Viz** | Collapsible output, syntax-highlighted results, diff-aware edits, tool timeline | Tames the noise from multi-tool turns | Medium |\n| **4: Navigation** | Colored diffs, pager, `/search`, `/undo`, interactive session picker, argument tab-completion | Power-user features | Medium-Large |\n| **5: Themes** | Named color themes, terminal capability detection, configurable spinners | Personalization | Medium |\n| **6: Full TUI** | Optional `ratatui` split-pane mode with scrollback, mouse, keyboard shortcuts | Major new mode (stretch goal) | XL |\n\n**Recommended start**: Phase 0 → Phase 1.1–1.2 → Phase 2.4 → Phase 3.1 (this gives the biggest bang for the buck).\n\nThe full plan with task-level detail, architecture diagrams, design principles, and risk assessment is saved to:  \n📄 `.omc/plans/tui-enhancement-plan.md`","type":"text"}],"role":"assistant","usage":{"cache_creation_input_tokens":0,"cache_read_input_tokens":0,"input_tokens":135612,"output_tokens":792}},{"blocks":[{"text":"save this analysis as a md file","type":"text"}],"role":"user"},{"blocks":[{"text":"\n\nThe analysis is already saved as a Markdown file at:\n\n📄 `.omc/plans/tui-enhancement-plan.md`\n\nLet me also save a copy at a more discoverable top-level location:","type":"text"},{"id":"toolu_01GJaYxrLrX7NnJWxH4huP5d","input":"{\"command\": \"cp /home/bellman/Workspace/clawd-code/rust/.omc/plans/tui-enhancement-plan.md /home/bellman/Workspace/clawd-code/rust/TUI-ENHANCEMENT-PLAN.md\"}","name":"bash","type":"tool_use"}],"role":"assistant","usage":{"cache_creation_input_tokens":0,"cache_read_input_tokens":0,"input_tokens":136414,"output_tokens":156}},{"blocks":[{"is_error":false,"output":"{\n  \"stdout\": \"\",\n  \"stderr\": \"\",\n  \"rawOutputPath\": null,\n  \"interrupted\": false,\n  \"isImage\": null,\n  \"backgroundTaskId\": null,\n  \"backgroundedByUser\": null,\n  \"assistantAutoBackgrounded\": null,\n  \"dangerouslyDisableSandbox\": null,\n  \"returnCodeInterpretation\": null,\n  \"noOutputExpected\": true,\n  \"structuredContent\": null,\n  \"persistedOutputPath\": null,\n  \"persistedOutputSize\": null,\n  \"sandboxStatus\": {\n    \"enabled\": true,\n    \"requested\": {\n      \"enabled\": true,\n      \"namespace_restrictions\": true,\n      \"network_isolation\": false,\n      \"filesystem_mode\": \"workspace-only\",\n      \"allowed_mounts\": []\n    },\n    \"supported\": true,\n    \"active\": true,\n    \"namespace_supported\": true,\n    \"namespace_active\": true,\n    \"network_supported\": true,\n    \"network_active\": false,\n    \"filesystem_mode\": \"workspace-only\",\n    \"filesystem_active\": true,\n    \"allowed_mounts\": [],\n    \"in_container\": false,\n    \"container_markers\": [],\n    \"fallback_reason\": null\n  }\n}","tool_name":"bash","tool_use_id":"toolu_01GJaYxrLrX7NnJWxH4huP5d","type":"tool_result"}],"role":"tool"},{"blocks":[{"text":"Done.

-# TUI Enhancement Plan — Claw Code (`rusty-claude-cli`)
-
-## Executive Summary
-
-This plan covers a comprehensive analysis of the current terminal user interface and proposes phased enhancements that will transform the existing REPL/prompt CLI into a polished, modern TUI experience — while preserving the existing clean architecture and test coverage.
-
----
-
-## 1. Current Architecture Analysis
-
-### Crate Map
-
-| Crate | Purpose | Lines | TUI Relevance |
-|---|---|---|---|
-| `rusty-claude-cli` | Main binary: REPL loop, arg parsing, rendering, API bridge | ~3,600 | **Primary TUI surface** |
-| `runtime` | Session, conversation loop, config, permissions, compaction | ~5,300 | Provides data/state |
-| `api` | Anthropic HTTP client + SSE streaming | ~1,500 | Provides stream events |
-| `commands` | Slash command metadata/parsing/help | ~470 | Drives command dispatch |
-| `tools` | 18 built-in tool implementations | ~3,500 | Tool execution display |
-
-### Current TUI Components
-
-| Component | File | What It Does Today | Quality |
-|---|---|---|---|
-| **Input** | `input.rs` (269 lines) | `rustyline`-based line editor with slash-command tab completion, Shift+Enter newline, history | ✅ Solid |
-| **Rendering** | `render.rs` (641 lines) | Markdown→terminal rendering (headings, lists, tables, code blocks with syntect highlighting, blockquotes), spinner widget | ✅ Good |
-| **App/REPL loop** | `main.rs` (3,159 lines) | The monolithic `LiveCli` struct: REPL loop, all slash command handlers, streaming output, tool call display, permission prompting, session management | ⚠️ Monolithic |
-| **Alt App** | `app.rs` (398 lines) | An earlier `CliApp` prototype with `ConversationClient`, stream event handling, `TerminalRenderer`, output format support | ⚠️ Appears unused/legacy |
-
-### Key Dependencies
-
-- **crossterm 0.28** — terminal control (cursor, colors, clear)
-- **pulldown-cmark 0.13** — Markdown parsing
-- **syntect 5** — syntax highlighting
-- **rustyline 15** — line editing with completion
-- **serde_json** — tool I/O formatting
-
-### Strengths
-
-1. **Clean rendering pipeline**: Markdown rendering is well-structured with state tracking, table rendering, code highlighting
-2. **Rich tool display**: Tool calls get box-drawing borders (`╭─ name ─╮`), results show ✓/✗ icons
-3. **Comprehensive slash commands**: 15 commands covering model switching, permissions, sessions, config, diff, export
-4. **Session management**: Full persistence, resume, list, switch, compaction
-5. **Permission prompting**: Interactive Y/N approval for restricted tool calls
-6. **Thorough tests**: Every formatting function, every parse path has unit tests
-
-### Weaknesses & Gaps
-
-1. **`main.rs` is a 3,159-line monolith** — all REPL logic, formatting, API bridging, session management, and tests in one file
-2. **No alternate-screen / full-screen layout** — everything is inline scrolling output
-3. **No progress bars** — only a single braille spinner; no indication of streaming progress or token counts during generation
-4. **No visual diff rendering** — `/diff` just dumps raw git diff text
-5. **No syntax highlighting in streamed output** — markdown rendering only applies to tool results, not to the main assistant response stream
-6. **No status bar / HUD** — model, tokens, session info not visible during interaction
-7. **No image/attachment preview** — `SendUserMessage` resolves attachments but never displays them
-8. **Streaming is char-by-char with artificial delay** — `stream_markdown` sleeps 8ms per whitespace-delimited chunk
-9. **No color theme customization** — hardcoded `ColorTheme::default()`
-10. **No resize handling** — no terminal size awareness for wrapping, truncation, or layout
-11. **Dual app structs** — `app.rs` has a separate `CliApp` that duplicates `LiveCli` from `main.rs`
-12. **No pager for long outputs** — `/status`, `/config`, `/memory` can overflow the viewport
-13. **Tool results not collapsible** — large bash outputs flood the screen
-14. **No thinking/reasoning indicator** — when the model is in "thinking" mode, no visual distinction
-15. **No auto-complete for tool arguments** — only slash command names complete
-

-
-## 2. Enhancement Plan
-
-### Phase 0: Structural Cleanup (Foundation)
-
-**Goal**: Break the monolith, remove dead code, establish the module structure for TUI work.
-
-| Task | Description | Effort |
-|---|---|---|
-| 0.1 | **Extract `LiveCli` into `app.rs`** — Move the entire `LiveCli` struct, its impl, and helpers (`format_*`, `render_*`, session management) out of `main.rs` into focused modules: `app.rs` (core), `format.rs` (report formatting), `session_manager.rs` (session CRUD) | M |
-| 0.2 | **Remove or merge the legacy `CliApp`** — The existing `app.rs` has an unused `CliApp` with its own `ConversationClient`-based rendering. Either delete it or merge its unique features (stream event handler pattern) into the active `LiveCli` | S |
-| 0.3 | **Extract `main.rs` arg parsing** — The current `parse_args()` is a hand-rolled parser that duplicates the clap-based `args.rs`. Consolidate on the hand-rolled parser (it's more feature-complete) and move it to `args.rs`, or adopt clap fully | S |
-| 0.4 | **Create a `tui/` module** — Introduce `crates/rusty-claude-cli/src/tui/mod.rs` as the namespace for all new TUI components: `status_bar.rs`, `layout.rs`, `tool_panel.rs`, etc. | S |
-
-### Phase 1: Status Bar & Live HUD
-
-**Goal**: Persistent information display during interaction.
-
-| Task | Description | Effort |
-|---|---|---|
-| 1.1 | **Terminal-size-aware status line** — Use `crossterm::terminal::size()` to render a bottom-pinned status bar showing: model name, permission mode, session ID, cumulative token count, estimated cost | M |
-| 1.2 | **Live token counter** — Update the status bar in real-time as `AssistantEvent::Usage` and `AssistantEvent::TextDelta` events arrive during streaming | M |
-| 1.3 | **Turn duration timer** — Show elapsed time for the current turn (the `showTurnDuration` config already exists in Config tool but isn't wired up) | S |
-| 1.4 | **Git branch indicator** — Display the current git branch in the status bar (already parsed via `parse_git_status_metadata`) | S |
-
-### Phase 2: Enhanced Streaming Output
-
-**Goal**: Make the main response stream visually rich and responsive.
-
-| Task | Description | Effort |
-|---|---|---|
-| 2.1 | **Live markdown rendering** — Instead of raw text streaming, buffer text deltas and incrementally render Markdown as it arrives (heading detection, bold/italic, inline code). The existing `TerminalRenderer::render_markdown` can be adapted for incremental use | L |
-| 2.2 | **Thinking indicator** — When extended thinking/reasoning is active, show a distinct animated indicator (e.g., `🧠 Reasoning...` with pulsing dots or a different spinner) instead of the generic `🦀 Thinking...` | S |
-| 2.3 | **Streaming progress bar** — Add an optional horizontal progress indicator below the spinner showing approximate completion (based on max_tokens vs. output_tokens so far) | M |
-| 2.4 | **Remove artificial stream delay** — The current `stream_markdown` sleeps 8ms per chunk. For tool results this is fine, but for the main response stream it should be immediate or configurable | S |
-
-### Phase 3: Tool Call Visualization
-
-**Goal**: Make tool execution legible and navigable.
-
-| Task | Description | Effort |
-|---|---|---|
-| 3.1 | **Collapsible tool output** — For tool results longer than N lines (configurable, default 15), show a summary with `[+] Expand` hint; pressing a key reveals the full output. Initially implement as truncation with a "full output saved to file" fallback | M |
-| 3.2 | **Syntax-highlighted tool results** — When tool results contain code (detected by tool name — `bash` stdout, `read_file` content, `REPL` output), apply syntect highlighting rather than rendering as plain text | M |
-| 3.3 | **Tool call timeline** — For multi-tool turns, show a compact summary: `🔧 bash → ✓ | read_file → ✓ | edit_file → ✓ (3 tools, 1.2s)` after all tool calls complete | S |
-| 3.4 | **Diff-aware edit_file display** — When `edit_file` succeeds, show a colored unified diff of the change instead of just `✓ edit_file: path` | M |
-| 3.5 | **Permission prompt enhancement** — Style the approval prompt with box drawing, color the tool name, show a one-line summary of what the tool will do | S |
-
-### Phase 4: Enhanced Slash Commands & Navigation
-
-**Goal**: Improve information display and add missing features.
-
-| Task | Description | Effort |
-|---|---|---|
-| 4.1 | **Colored `/diff` output** — Parse the git diff and render it with red/green coloring for removals/additions, similar to `delta` or `diff-so-fancy` | M |
-| 4.2 | **Pager for long outputs** — When `/status`, `/config`, `/memory`, or `/diff` produce output longer than the terminal height, pipe through an internal pager (scroll with j/k/q) or external `$PAGER` | M |
-| 4.3 | **`/search` command** — Add a new command to search conversation history by keyword | M |
-| 4.4 | **`/undo` command** — Undo the last file edit by restoring from the `originalFile` data in `write_file`/`edit_file` tool results | M |
-| 4.5 | **Interactive session picker** — Replace the text-based `/session list` with an interactive fuzzy-filterable list (up/down arrows to select, enter to switch) | L |
-| 4.6 | **Tab completion for tool arguments** — Extend `SlashCommandHelper` to complete file paths after `/export`, model names after `/model`, session IDs after `/session switch` | M |
-
-### Phase 5: Color Themes & Configuration
-
-**Goal**: User-customizable visual appearance.
-
-| Task | Description | Effort |
-|---|---|---|
-| 5.1 | **Named color themes** — Add `dark` (current default), `light`, `solarized`, `catppuccin` themes. Wire to the existing `Config` tool's `theme` setting | M |
-| 5.2 | **ANSI-256 / truecolor detection** — Detect terminal capabilities and fall back gracefully (no colors → 16 colors → 256 → truecolor) | M |
-| 5.3 | **Configurable spinner style** — Allow choosing between braille dots, bar, moon phases, etc. | S |
-| 5.4 | **Banner customization** — Make the ASCII art banner optional or configurable via settings | S |
-
-### Phase 6: Full-Screen TUI Mode (Stretch)
-
-**Goal**: Optional alternate-screen layout for power users.
-
-| Task | Description | Effort |
-|---|---|---|
-| 6.1 | **Add `ratatui` dependency** — Introduce `ratatui` (terminal UI framework) as an optional dependency for the full-screen mode | S |
-| 6.2 | **Split-pane layout** — Top pane: conversation with scrollback; Bottom pane: input area; Right sidebar (optional): tool status/todo list | XL |
-| 6.3 | **Scrollable conversation view** — Navigate past messages with PgUp/PgDn, search within conversation | L |
-| 6.4 | **Keyboard shortcuts panel** — Show `?` help overlay with all keybindings | M |
-| 6.5 | **Mouse support** — Click to expand tool results, scroll conversation, select text for copy | L |
-
----
-
-## 3. Priority Recommendation
-
-### Immediate (High Impact, Moderate Effort)
-
-1. **Phase 0** — Essential cleanup. The 3,159-line `main.rs` is the #1 maintenance risk and blocks clean TUI additions.
-2. **Phase 1.1–1.2** — Status bar with live tokens. Highest-impact UX win: users constantly want to know token usage.
-3. **Phase 2.4** — Remove artificial delay. Low effort, immediately noticeable improvement.
-4. **Phase 3.1** — Collapsible tool output. Large bash outputs currently wreck readability.
-
-### Near-Term (Next Sprint)
-
-5. **Phase 2.1** — Live markdown rendering. Makes the core interaction feel polished.
-6. **Phase 3.2** — Syntax-highlighted tool results.
-7. **Phase 3.4** — Diff-aware edit display.
-8. **Phase 4.1** — Colored diff for `/diff`.
-
-### Longer-Term
-
-9. **Phase 5** — Color themes (user demand-driven).
-10. **Phase 4.2–4.6** — Enhanced navigation and commands.
-11. **Phase 6** — Full-screen mode (major undertaking, evaluate after earlier phases ship).
-

-
-## 4. Architecture Recommendations
-
-### Module Structure After Phase 0
-
-```
-crates/rusty-claude-cli/src/
-├── main.rs              # Entrypoint, arg dispatch only (~100 lines)
-├── args.rs              # CLI argument parsing (consolidate existing two parsers)
-├── app.rs               # LiveCli struct, REPL loop, turn execution
-├── format.rs            # All report formatting (status, cost, model, permissions, etc.)
-├── session_mgr.rs       # Session CRUD: create, resume, list, switch, persist
-├── init.rs              # Repo initialization (unchanged)
-├── input.rs             # Line editor (unchanged, minor extensions)
-├── render.rs            # TerminalRenderer, Spinner (extended)
-└── tui/
-    ├── mod.rs           # TUI module root
-    ├── status_bar.rs    # Persistent bottom status line
-    ├── tool_panel.rs    # Tool call visualization (boxes, timelines, collapsible)
-    ├── diff_view.rs     # Colored diff rendering
-    ├── pager.rs         # Internal pager for long outputs
-    └── theme.rs         # Color theme definitions and selection
-```
-
-### Key Design Principles
-
-1. **Keep the inline REPL as the default** — Full-screen TUI should be opt-in (`--tui` flag)
-2. **Everything testable without a terminal** — All formatting functions take `&mut impl Write`, never assume stdout directly
-3. **Streaming-first** — Rendering should work incrementally, not buffering the entire response
-4. **Respect `crossterm` for all terminal control** — Don't mix raw ANSI escape codes with crossterm (the current codebase does this in the startup banner)
-5. **Feature-gate heavy dependencies** — `ratatui` should be behind a `full-tui` feature flag
-
----
-
-## 5. Risk Assessment
-
-| Risk | Mitigation |
-|---|---|
-| Breaking the working REPL during refactor | Phase 0 is pure restructuring with existing test coverage as safety net |
-| Terminal compatibility issues (tmux, SSH, Windows) | Rely on crossterm's abstraction; test in degraded environments |
-| Performance regression with rich rendering | Profile before/after; keep the fast path (raw streaming) always available |
-| Scope creep into Phase 6 | Ship Phases 0–3 as a coherent release before starting Phase 6 |
-| `app.rs` vs `main.rs` confusion | Phase 0.2 explicitly resolves this by removing the legacy `CliApp` |

-
-This file provides guidance to Claw Code (clawcode.dev) when working with code in this repository.
-
-## Detected stack
-- Languages: Rust.
-- Frameworks: none detected from the supported starter markers.
-
-## Verification
-- From the repository root, run Rust formatting with `scripts/fmt.sh` (or `scripts/fmt.sh --check` for CI-style checks). From this `rust/` directory, the equivalent command is `../scripts/fmt.sh`. Root-level `cargo fmt --manifest-path rust/Cargo.toml` is not the supported formatting command.
-- From this `rust/` directory, run Rust verification with `cargo clippy --workspace --all-targets -- -D warnings` and `cargo test --workspace`.
-
-## Working agreement
-- Prefer small, reviewable changes and keep generated bootstrap files aligned with actual repo workflows.
-- Keep shared defaults in `.claw.json`; reserve `.claw/settings.local.json` for machine-local overrides.
-- Do not overwrite existing `CLAUDE.md` content automatically; update it intentionally when repo workflows change.

-# Mock LLM parity harness
-
-This milestone adds a deterministic Anthropic-compatible mock service plus a reproducible CLI harness for the Rust `claw` binary.
-
-## Artifacts
-
-- `crates/mock-anthropic-service/` — mock `/v1/messages` service
-- `crates/rusty-claude-cli/tests/mock_parity_harness.rs` — end-to-end clean-environment harness
-- `scripts/run_mock_parity_harness.sh` — convenience wrapper
-
-## Scenarios
-
-The harness runs these scripted scenarios against a fresh workspace and isolated environment variables:
-
-1. `streaming_text`
-2. `read_file_roundtrip`
-3. `grep_chunk_assembly`
-4. `write_file_allowed`
-5. `write_file_denied`
-6. `multi_tool_turn_roundtrip`
-7. `bash_stdout_roundtrip`
-8. `bash_permission_prompt_approved`
-9. `bash_permission_prompt_denied`
-10. `plugin_tool_roundtrip`
-11. `auto_compact_triggered`
-12. `token_cost_reporting`
-
-## Run
-
-```bash
-cd rust/
-./scripts/run_mock_parity_harness.sh
-```
-
-Behavioral checklist / parity diff:
-
-```bash
-cd rust/
-python3 scripts/run_mock_parity_diff.py
-```
-
-Scenario-to-PARITY mappings live in `mock_parity_scenarios.json`; keep this manifest aligned with `rust/crates/rusty-claude-cli/tests/mock_parity_harness.rs` and `PARITY.md` via `python3 scripts/run_mock_parity_diff.py --no-run`.
-
-## Manual mock server
-
-```bash
-cd rust/
-cargo run -p mock-anthropic-service -- --bind 127.0.0.1:0
-```
-
-The server prints `MOCK_ANTHROPIC_BASE_URL=...`; point `ANTHROPIC_BASE_URL` at that URL and use any non-empty `ANTHROPIC_API_KEY`.

-### Real Implementations (behavioral parity — varying depth)
-
-| Tool | Rust Impl | Behavioral Notes |
-|------|-----------|-----------------|
-| **bash** | `runtime::bash` 283 LOC | subprocess exec, timeout, background, sandbox — **strong parity**. 9/9 requested validation submodules are now tracked as complete via `36dac6c`, with on-main sandbox + permission enforcement runtime support |
-| **read_file** | `runtime::file_ops` | offset/limit read — **good parity** |
-| **write_file** | `runtime::file_ops` | file create/overwrite — **good parity** |
-| **edit_file** | `runtime::file_ops` | old/new string replacement — **good parity**. Missing: replace_all was recently added |
-| **glob_search** | `runtime::file_ops` | glob pattern matching — **good parity** |
-| **grep_search** | `runtime::file_ops` | ripgrep-style search — **good parity** |
-| **WebFetch** | `tools` | URL fetch + content extraction — **moderate parity** (need to verify content truncation, redirect handling vs upstream) |
-| **WebSearch** | `tools` | search query execution — **moderate parity** |
-| **TodoWrite** | `tools` | todo/note persistence — **moderate parity** |
-| **Skill** | `tools` | skill discovery/install — **moderate parity** |
-| **Agent** | `tools` | agent delegation — **moderate parity** |
-| **TaskCreate** | `runtime::task_registry` + `tools` | in-memory task creation wired into tool dispatch — **good parity** |
-| **TaskGet** | `runtime::task_registry` + `tools` | task lookup + metadata payload — **good parity** |
-| **TaskList** | `runtime::task_registry` + `tools` | registry-backed task listing — **good parity** |

-
-### Stubs Only (surface parity, no behavior)
-
-| Tool | Status | Notes |
-|------|--------|-------|
-| **AskUserQuestion** | stub | needs live user I/O integration |
-| **McpAuth** | stub | needs full auth UX beyond the MCP lifecycle bridge |
-| **RemoteTrigger** | stub | needs HTTP client |
-| **TestingPermission** | stub | test-only, low priority |
-
-## Slash Commands: 67/141 upstream entries
-
-- 27 original specs (pre-today) — all with real handlers
-- 40 new specs — parse + stub handler ("not yet implemented")
-- Remaining ~74 upstream entries are internal modules/dialogs/steps, not user `/commands`
-
-### Behavioral Feature Checkpoints (completed work + remaining gaps)
-
-**Bash tool — 9/9 requested validation submodules complete:**
-- [x] `sedValidation` — validate sed commands before execution
-- [x] `pathValidation` — validate file paths in commands
-- [x] `readOnlyValidation` — block writes in read-only mode
-- [x] `destructiveCommandWarning` — warn on rm -rf, etc.
-- [x] `commandSemantics` — classify command intent
-- [x] `bashPermissions` — permission gating per command type
-- [x] `bashSecurity` — security checks
-- [x] `modeValidation` — validate against current permission mode
-- [x] `shouldUseSandbox` — sandbox decision logic
-
-Harness note: milestone 2 validates bash success plus workspace-write escalation approve/deny flows; dedicated validation submodules landed in `36dac6c`, and on-main runtime also carries sandbox + permission enforcement.
-
-**File tools — completed checkpoint:**
-- [x] Path traversal prevention (symlink following, ../ escapes)
-- [x] Size limits on read/write
-- [x] Binary file detection
-- [x] Permission mode enforcement (read-only vs workspace-write)
-
-Harness note: read_file, grep_search, write_file allow/deny, and multi-tool same-turn assembly are now covered by the mock parity harness; file edge cases + permission enforcement landed in `a98f2b6` and `336f820`.
-
-**Config/Plugin/MCP flows:**
-- [x] Full MCP server lifecycle (connect, list tools, call tool, disconnect)
-- [ ] Plugin install/enable/disable/uninstall full flow
-- [ ] Config merge precedence (user > project > local)
-
-Harness note: external plugin discovery + execution is now covered via `plugin_tool_roundtrip`; MCP lifecycle landed in `cc0f92e`, while plugin lifecycle + config merge precedence remain open.
-
-## Runtime Behavioral Gaps
-
-- [x] Permission enforcement across all tools (read-only, workspace-write, danger-full-access)
-- [ ] Output truncation (large stdout/file content)
-- [ ] Session compaction behavior matching
-- [ ] Token counting / cost tracking accuracy
-- [x] Streaming response support validated by the mock parity harness
-
-Harness note: current coverage now includes write-file denial, bash escalation approve/deny, and plugin workspace-write execution paths; permission enforcement landed in `336f820`.
-
-## Migration Readiness
-
-- [x] `PARITY.md` maintained and honest
-- [ ] No `#[ignore]` tests hiding failures (only 1 allowed: `live_stream_smoke_test`)
-- [ ] CI green on every commit
-- [ ] Codebase shape clean for handoff

-# 🦞 Claw Code — Rust Implementation
-
-A high-performance Rust rewrite of the Claw Code CLI agent harness. Built for speed, safety, and native tool execution.
-
-For a task-oriented guide with copy/paste examples, see [`../USAGE.md`](../USAGE.md).
-
-## Quick Start
-
-```bash
-# Inspect available commands
-cd rust/
-cargo run -p rusty-claude-cli -- --help
-
-# Build the workspace
-cargo build --workspace
-
-# Run the interactive REPL
-cargo run -p rusty-claude-cli -- --model claude-opus-4-7
-
-# One-shot prompt
-cargo run -p rusty-claude-cli -- prompt "explain this codebase"
-
-# JSON output for automation
-cargo run -p rusty-claude-cli -- --output-format json prompt "summarize src/main.rs"
-```
-
-## Configuration
-
-Set your API credentials:
-
-```bash
-export ANTHROPIC_API_KEY="sk-ant-..."
-# Or use a proxy
-export ANTHROPIC_BASE_URL="https://your-proxy.com"
-```
-
-Or provide an OAuth bearer token directly:
-
-```bash
-export ANTHROPIC_AUTH_TOKEN="anthropic-oauth-or-proxy-bearer-token"
-```
-
-For local OpenAI-compatible servers such as Ollama, including Qwen reasoning
-models, see [`../docs/local-openai-compatible-providers.md`](../docs/local-openai-compatible-providers.md).
-Use the exact model tag exposed by the server, for example `qwen3:latest`, and
-prefer `OLLAMA_HOST` for Ollama-specific local routing.
-
-## Mock parity harness
-
-The workspace now includes a deterministic Anthropic-compatible mock service and a clean-environment CLI harness for end-to-end parity checks.
-
-```bash
-cd rust/
-
-# Run the scripted clean-environment harness
-./scripts/run_mock_parity_harness.sh
-
-# Or start the mock service manually for ad hoc CLI runs
-cargo run -p mock-anthropic-service -- --bind 127.0.0.1:0
-```
-
-Harness coverage:
-
-- `streaming_text`
-- `read_file_roundtrip`
-- `grep_chunk_assembly`
-- `write_file_allowed`
-- `write_file_denied`
-- `multi_tool_turn_roundtrip`
-- `bash_stdout_roundtrip`
-- `bash_permission_prompt_approved`
-- `bash_permission_prompt_denied`
-- `plugin_tool_roundtrip`
-
-Primary artifacts:
-
-- `crates/mock-anthropic-service/` — reusable mock Anthropic-compatible service
-- `crates/rusty-claude-cli/tests/mock_parity_harness.rs` — clean-env CLI harness
-- `scripts/run_mock_parity_harness.sh` — reproducible wrapper
-- `scripts/run_mock_parity_diff.py` — scenario checklist + PARITY mapping runner
-- `mock_parity_scenarios.json` — scenario-to-PARITY manifest

-
-`claw acp` is a local discoverability surface for editor-first users: it reports the current ACP/Zed status without starting the runtime. As of April 16, 2026, claw-code does **not** ship an ACP/Zed daemon or JSON-RPC entrypoint yet, and `claw acp serve` is only a status alias until the real protocol surface lands. Status queries exit 0 and expose the same machine-readable contract via `--output-format json`; malformed ACP invocations exit 1 with `kind: unsupported_acp_invocation`.
-`--output-format` accepts `text` or `json` in any casing. `CLAW_OUTPUT_FORMAT=json` selects JSON as the default for non-interactive commands, explicit flags override it, repeated flags warn on stderr, and status JSON exposes `format_source`, `format_raw`, and `format_overridden`. Help and doctor output also surface `CLAW_LOG` / `RUST_LOG` as the logging environment knobs.
-`claw version --output-format json` is the provenance probe for automation: it reports full `git_sha`, derived `git_sha_short`, `is_dirty`, `branch`, `commit_date`, `commit_timestamp`, `rustc_version`, runtime `executable_path`, and `binary_provenance`; the text report is available as `human_readable` instead of a duplicate `message` field.
-`status --output-format json` reports loaded project memory files under `workspace.memory_files[]` with each file's `path`, `source` (`claude_md`, `claw_md`, `agents_md`, or scoped/rule sources), `origin`, `scope_path`, `outside_project`, `chars`, and `contributes`; `claw doctor --output-format json` includes a dedicated `memory` check. Root instruction-file priority is `CLAUDE.md`, then `CLAW.md`, then `AGENTS.md`, discovery is bounded to the current git root when present (otherwise cwd only), and all non-duplicate loaded files contribute to the rendered system prompt.
-`claw mcp --output-format json` reports partial MCP config success: valid servers remain in `servers[]` while malformed siblings appear in `invalid_servers[]`, with `total_configured`, `valid_count`, and `invalid_count` split out for automation. `status` mirrors this as `mcp_validation`, and doctor includes an `mcp validation` check.
-`status --output-format json` also reports partial hook config success under `hook_validation`: valid hook entries are retained while malformed or unknown-event siblings appear in `invalid_hooks[]`, with `valid_count`, `invalid_count`, and typed `kind` fields (`invalid_hooks_config` or `unknown_hook_event`) for automation. `doctor --output-format json` includes a `hook validation` check, and `config --output-format json` includes `hook_validation` metadata with degraded status when invalid entries exist.
-Shorthand prompt mode honors the POSIX `--` end-of-flags separator, so `claw -- "-prompt-with-dash"` and unknown dash-prefixed non-flag text stay on the prompt path instead of being treated as CLI options.
-`claw dump-manifests` is self-contained: it emits the Rust resolver inventory for the selected workspace (commands, tools, agents, skills, and bootstrap phases) without requiring an upstream Claude Code TypeScript checkout. Use `--manifests-dir PATH` only to scope resolver discovery to another directory.
-
-The command surface is moving quickly. For the canonical live help text, run:
-
-```bash
-cargo run -p rusty-claude-cli -- --help
-```
-
-## Slash Commands (REPL)
-
-Tab completion expands slash commands, model aliases, permission modes, and recent session IDs.
-
-The REPL now exposes a much broader surface than the original minimal shell:
-
-- session / visibility: `/help`, `/status`, `/sandbox`, `/cost`, `/resume`, `/session`, `/version`, `/usage`, `/stats`
-- workspace / git: `/compact`, `/clear`, `/config`, `/memory`, `/init`, `/diff`, `/commit`, `/pr`, `/issue`, `/export`, `/hooks`, `/files`, `/release-notes`
-- discovery / debugging: `/mcp`, `/agents`, `/skills`, `/doctor`, `/tasks`, `/context`, `/desktop`
-- automation / analysis: `/review`, `/advisor`, `/insights`, `/security-review`, `/subagent`, `/team`, `/telemetry`, `/providers`, `/cron`, and more
-- plugin management: `/plugin` (with aliases `/plugins`, `/marketplace`)
-
-Notable claw-first surfaces now available directly in slash form:
-- `/skills [list|show <name>|install <path>|uninstall <name>|help]`
-- `/agents [list|show <name>|create <name>|help]`
-- `/mcp [list|show <server>|help]`
-- `/doctor`
-- `/plugin [list|install <path>|enable <name>|disable <name>|uninstall <id>|update <id>]`
-- `/subagent [list|steer <target> <msg>|kill <id>]`
-
-See [`../USAGE.md`](../USAGE.md) for usage examples and run `cargo run -p rusty-claude-cli -- --help` for the live canonical command list.

-# TUI Enhancement Plan — Claw Code (`rusty-claude-cli`)
-
-## Executive Summary
-
-This plan covers a comprehensive analysis of the current terminal user interface and proposes phased enhancements that will transform the existing REPL/prompt CLI into a polished, modern TUI experience — while preserving the existing clean architecture and test coverage.
-
----
-
-## 1. Current Architecture Analysis
-
-### Crate Map
-
-| Crate | Purpose | Lines | TUI Relevance |
-|---|---|---|---|
-| `rusty-claude-cli` | Main binary: REPL loop, arg parsing, rendering, API bridge | ~3,600 | **Primary TUI surface** |
-| `runtime` | Session, conversation loop, config, permissions, compaction | ~5,300 | Provides data/state |
-| `api` | Anthropic HTTP client + SSE streaming | ~1,500 | Provides stream events |
-| `commands` | Slash command metadata/parsing/help | ~470 | Drives command dispatch |
-| `tools` | 18 built-in tool implementations | ~3,500 | Tool execution display |
-
-### Current TUI Components
-
-> Note: The legacy prototype files `app.rs` and `args.rs` were removed on 2026-04-05.
-> References below describe future extraction targets, not current tracked source files.
-
-| Component | File | What It Does Today | Quality |
-|---|---|---|---|
-| **Input** | `input.rs` (269 lines) | `rustyline`-based line editor with slash-command tab completion, Shift+Enter newline, history | ✅ Solid |
-| **Rendering** | `render.rs` (641 lines) | Markdown→terminal rendering (headings, lists, tables, code blocks with syntect highlighting, blockquotes), spinner widget | ✅ Good |
-| **App/REPL loop** | `main.rs` (3,159 lines) | The monolithic `LiveCli` struct: REPL loop, all slash command handlers, streaming output, tool call display, permission prompting, session management | ⚠️ Monolithic |
-
-### Key Dependencies
-
-- **crossterm 0.28** — terminal control (cursor, colors, clear)
-- **pulldown-cmark 0.13** — Markdown parsing
-- **syntect 5** — syntax highlighting
-- **rustyline 15** — line editing with completion
-- **serde_json** — tool I/O formatting
-
-### Strengths
-
-1. **Clean rendering pipeline**: Markdown rendering is well-structured with state tracking, table rendering, code highlighting
-2. **Rich tool display**: Tool calls get box-drawing borders (`╭─ name ─╮`), results show ✓/✗ icons
-3. **Comprehensive slash commands**: 15 commands covering model switching, permissions, sessions, config, diff, export
-4. **Session management**: Full persistence, resume, list, switch, compaction
-5. **Permission prompting**: Interactive Y/N approval for restricted tool calls
-6. **Thorough tests**: Every formatting function, every parse path has unit tests
-
-### Weaknesses & Gaps
-
-1. **`main.rs` is a 3,159-line monolith** — all REPL logic, formatting, API bridging, session management, and tests in one file
-2. **No alternate-screen / full-screen layout** — everything is inline scrolling output
-3. **No progress bars** — only a single braille spinner; no indication of streaming progress or token counts during generation
-4. **No visual diff rendering** — `/diff` just dumps raw git diff text
-5. **No syntax highlighting in streamed output** — markdown rendering only applies to tool results, not to the main assistant response stream
-6. **No status bar / HUD** — model, tokens, session info not visible during interaction
-7. **No image/attachment preview** — `SendUserMessage` resolves attachments but never displays them
-8. **Streaming is char-by-char with artificial delay** — `stream_markdown` sleeps 8ms per whitespace-delimited chunk
-9. **No color theme customization** — hardcoded `ColorTheme::default()`
-10. **No resize handling** — no terminal size awareness for wrapping, truncation, or layout
-11. **Historical dual app split** — the repo previously carried a separate `CliApp` prototype alongside `LiveCli`; the prototype is gone, but the monolithic `main.rs` still needs extraction
-12. **No pager for long outputs** — `/status`, `/config`, `/memory` can overflow the viewport
-13. **Tool results not collapsible** — large bash outputs flood the screen
-14. **No thinking/reasoning indicator** — when the model is in "thinking" mode, no visual distinction
-15. **No auto-complete for tool arguments** — only slash command names complete
-

-
-## 2. Enhancement Plan
-
-### Phase 0: Structural Cleanup (Foundation)
-
-**Goal**: Break the monolith, remove dead code, establish the module structure for TUI work.
-
-| Task | Description | Effort |
-|---|---|---|
-| 0.1 | **Extract `LiveCli` into `app.rs`** — Move the entire `LiveCli` struct, its impl, and helpers (`format_*`, `render_*`, session management) out of `main.rs` into focused modules: `app.rs` (core), `format.rs` (report formatting), `session_manager.rs` (session CRUD) | M |
-| 0.2 | **Keep the legacy `CliApp` removed** — The old `CliApp` prototype has already been deleted; if any unique ideas remain valuable (for example stream event handler patterns), reintroduce them intentionally inside the active `LiveCli` extraction rather than restoring the old file wholesale | S |
-| 0.3 | **Extract `main.rs` arg parsing** — The current `parse_args()` is still a hand-rolled parser in `main.rs`. If parsing is extracted later, do it into a newly-introduced module intentionally rather than reviving the removed prototype `args.rs` by accident | S |
-| 0.4 | **Create a `tui/` module** — Introduce `crates/rusty-claude-cli/src/tui/mod.rs` as the namespace for all new TUI components: `status_bar.rs`, `layout.rs`, `tool_panel.rs`, etc. | S |
-
-### Phase 1: Status Bar & Live HUD
-
-**Goal**: Persistent information display during interaction.
-
-| Task | Description | Effort |
-|---|---|---|
-| 1.1 | **Terminal-size-aware status line** — Use `crossterm::terminal::size()` to render a bottom-pinned status bar showing: model name, permission mode, session ID, cumulative token count, estimated cost | M |
-| 1.2 | **Live token counter** — Update the status bar in real-time as `AssistantEvent::Usage` and `AssistantEvent::TextDelta` events arrive during streaming | M |
-| 1.3 | **Turn duration timer** — Show elapsed time for the current turn (the `showTurnDuration` config already exists in Config tool but isn't wired up) | S |
-| 1.4 | **Git branch indicator** — Display the current git branch in the status bar (already parsed via `parse_git_status_metadata`) | S |
-
-### Phase 2: Enhanced Streaming Output
-
-**Goal**: Make the main response stream visually rich and responsive.
-
-| Task | Description | Effort |
-|---|---|---|
-| 2.1 | **Live markdown rendering** — Instead of raw text streaming, buffer text deltas and incrementally render Markdown as it arrives (heading detection, bold/italic, inline code). The existing `TerminalRenderer::render_markdown` can be adapted for incremental use | L |
-| 2.2 | **Thinking indicator** — When extended thinking/reasoning is active, show a distinct animated indicator (e.g., `🧠 Reasoning...` with pulsing dots or a different spinner) instead of the generic `🦀 Thinking...` | S |
-| 2.3 | **Streaming progress bar** — Add an optional horizontal progress indicator below the spinner showing approximate completion (based on max_tokens vs. output_tokens so far) | M |
-| 2.4 | **Remove artificial stream delay** — The current `stream_markdown` sleeps 8ms per chunk. For tool results this is fine, but for the main response stream it should be immediate or configurable | S |
-
-### Phase 3: Tool Call Visualization
-
-**Goal**: Make tool execution legible and navigable.
-
-| Task | Description | Effort |
-|---|---|---|
-| 3.1 | **Collapsible tool output** — For tool results longer than N lines (configurable, default 15), show a summary with `[+] Expand` hint; pressing a key reveals the full output. Initially implement as truncation with a "full output saved to file" fallback | M |
-| 3.2 | **Syntax-highlighted tool results** — When tool results contain code (detected by tool name — `bash` stdout, `read_file` content, `REPL` output), apply syntect highlighting rather than rendering as plain text | M |
-| 3.3 | **Tool call timeline** — For multi-tool turns, show a compact summary: `🔧 bash → ✓ | read_file → ✓ | edit_file → ✓ (3 tools, 1.2s)` after all tool calls complete | S |
-| 3.4 | **Diff-aware edit_file display** — When `edit_file` succeeds, show a colored unified diff of the change instead of just `✓ edit_file: path` | M |
-| 3.5 | **Permission prompt enhancement** — Style the approval prompt with box drawing, color the tool name, show a one-line summary of what the tool will do | S |
-
-### Phase 4: Enhanced Slash Commands & Navigation
-
-**Goal**: Improve information display and add missing features.
-
-| Task | Description | Effort |
-|---|---|---|
-| 4.1 | **Colored `/diff` output** — Parse the git diff and render it with red/green coloring for removals/additions, similar to `delta` or `diff-so-fancy` | M |
-| 4.2 | **Pager for long outputs** — When `/status`, `/config`, `/memory`, or `/diff` produce output longer than the terminal height, pipe through an internal pager (scroll with j/k/q) or external `$PAGER` | M |
-| 4.3 | **`/search` command** — Add a new command to search conversation history by keyword | M |
-| 4.4 | **`/undo` command** — Undo the last file edit by restoring from the `originalFile` data in `write_file`/`edit_file` tool results | M |
-| 4.5 | **Interactive session picker** — Replace the text-based `/session list` with an interactive fuzzy-filterable list (up/down arrows to select, enter to switch) | L |
-| 4.6 | **Tab completion for tool arguments** — Extend `SlashCommandHelper` to complete file paths after `/export`, model names after `/model`, session IDs after `/session switch` | M |
-
-### Phase 5: Color Themes & Configuration
-
-**Goal**: User-customizable visual appearance.
-
-| Task | Description | Effort |
-|---|---|---|
-| 5.1 | **Named color themes** — Add `dark` (current default), `light`, `solarized`, `catppuccin` themes. Wire to the existing `Config` tool's `theme` setting | M |
-| 5.2 | **ANSI-256 / truecolor detection** — Detect terminal capabilities and fall back gracefully (no colors → 16 colors → 256 → truecolor) | M |
-| 5.3 | **Configurable spinner style** — Allow choosing between braille dots, bar, moon phases, etc. | S |
-| 5.4 | **Banner customization** — Make the ASCII art banner optional or configurable via settings | S |
-
-### Phase 6: Full-Screen TUI Mode (Stretch)
-
-**Goal**: Optional alternate-screen layout for power users.
-
-| Task | Description | Effort |
-|---|---|---|
-| 6.1 | **Add `ratatui` dependency** — Introduce `ratatui` (terminal UI framework) as an optional dependency for the full-screen mode | S |
-| 6.2 | **Split-pane layout** — Top pane: conversation with scrollback; Bottom pane: input area; Right sidebar (optional): tool status/todo list | XL |
-| 6.3 | **Scrollable conversation view** — Navigate past messages with PgUp/PgDn, search within conversation | L |
-| 6.4 | **Keyboard shortcuts panel** — Show `?` help overlay with all keybindings | M |
-| 6.5 | **Mouse support** — Click to expand tool results, scroll conversation, select text for copy | L |
-
----
-
-## 3. Priority Recommendation
-
-### Immediate (High Impact, Moderate Effort)
-
-1. **Phase 0** — Essential cleanup. The 3,159-line `main.rs` is the #1 maintenance risk and blocks clean TUI additions.
-2. **Phase 1.1–1.2** — Status bar with live tokens. Highest-impact UX win: users constantly want to know token usage.
-3. **Phase 2.4** — Remove artificial delay. Low effort, immediately noticeable improvement.
-4. **Phase 3.1** — Collapsible tool output. Large bash outputs currently wreck readability.
-
-### Near-Term (Next Sprint)
-
-5. **Phase 2.1** — Live markdown rendering. Makes the core interaction feel polished.
-6. **Phase 3.2** — Syntax-highlighted tool results.
-7. **Phase 3.4** — Diff-aware edit display.
-8. **Phase 4.1** — Colored diff for `/diff`.
-
-### Longer-Term
-
-9. **Phase 5** — Color themes (user demand-driven).
-10. **Phase 4.2–4.6** — Enhanced navigation and commands.
-11. **Phase 6** — Full-screen mode (major undertaking, evaluate after earlier phases ship).

-## 4. Architecture Recommendations
-
-### Module Structure After Phase 0
-
-```
-crates/rusty-claude-cli/src/
-├── main.rs              # Entrypoint, arg dispatch only (~100 lines)
-├── args.rs              # CLI argument parsing (consolidate existing two parsers)
-├── app.rs               # LiveCli struct, REPL loop, turn execution
-├── format.rs            # All report formatting (status, cost, model, permissions, etc.)
-├── session_mgr.rs       # Session CRUD: create, resume, list, switch, persist
-├── init.rs              # Repo initialization (unchanged)
-├── input.rs             # Line editor (unchanged, minor extensions)
-├── render.rs            # TerminalRenderer, Spinner (extended)
-└── tui/
-    ├── mod.rs           # TUI module root
-    ├── status_bar.rs    # Persistent bottom status line
-    ├── tool_panel.rs    # Tool call visualization (boxes, timelines, collapsible)
-    ├── diff_view.rs     # Colored diff rendering
-    ├── pager.rs         # Internal pager for long outputs
-    └── theme.rs         # Color theme definitions and selection
-```
-
-### Key Design Principles
-
-1. **Keep the inline REPL as the default** — Full-screen TUI should be opt-in (`--tui` flag)
-2. **Everything testable without a terminal** — All formatting functions take `&mut impl Write`, never assume stdout directly
-3. **Streaming-first** — Rendering should work incrementally, not buffering the entire response
-4. **Respect `crossterm` for all terminal control** — Don't mix raw ANSI escape codes with crossterm (the current codebase does this in the startup banner)
-5. **Feature-gate heavy dependencies** — `ratatui` should be behind a `full-tui` feature flag
-
----
-
-## 5. Risk Assessment
-
-| Risk | Mitigation |
-|---|---|
-| Breaking the working REPL during refactor | Phase 0 is pure restructuring with existing test coverage as safety net |
-| Terminal compatibility issues (tmux, SSH, Windows) | Rely on crossterm's abstraction; test in degraded environments |
-| Performance regression with rich rendering | Profile before/after; keep the fast path (raw streaming) always available |
-| Scope creep into Phase 6 | Ship Phases 0–3 as a coherent release before starting Phase 6 |
-| Historical `app.rs` vs `main.rs` confusion | Keep the legacy prototype removed and avoid reintroducing a second app surface accidentally during extraction |

+### Role
+You serve as a senior systems engineer with deep expertise in Rust, TypeScript, Bat, and Shell scripting. Deliver expert-level analysis and solutions across these domains. Prioritize first-principles reasoning, explicit trade-off analysis, and root-cause diagnosis over symptomatic surface fixes.
+### Writing standards
+- Support conceptual explanation with tangible examples.
+- Reply using the user's language. Write all code blocks, technical identifiers, and code comments in English.
+- Apply bold formatting selectively to mark core viewpoints and critical constraints.
+- Represent tabular data via Markdown table syntax for clearer visual hierarchy.
+- Write standardized, valid Mermaid syntax and produce neatly structured, legible diagrams matching user requirements.
+- The implementation requires explicit lifetime annotations.
+### Rationale & Trade-offs
+1.  **Semantic precision**: The rule focuses emphasis on key points and critical constraints, preserving highlighting weight by keeping usage selective.
+2.  **Logical grouping**: The rule is placed alongside other typography rules (character set, table syntax) to group all formatting constraints, maintaining a clear hierarchical rule structure.
+3.  **Tone alignment**: Adopts formal, engineering-standard phrasing (`judiciously`, `scannability`) consistent with the rest of the specification, with no colloquial wording.
+### Execution Rules
+- Validate all code for correctness and edge-case coverage before output.
+- Treat all bracketed instructions as mandatory requirements.
+### Tool Preference
+- Prefer `rg` (ripgrep) over `grep` or `read` for code search, and `fd` for file search.
+- Use `bash` to run `rg`.
+- **Caveat**: `rg`/`fd` silently return zero results on Chinese/non-ASCII paths in Git Bash on Windows. For non-ASCII paths, fall back to PowerShell (`Get-ChildItem | Select-String`) or `read_file` instead of assuming the file is missing.
+### Windows Shell Interop
+- `bash` is the host shell; PowerShell runs as a child process via `powershell -Command '...'`.
+- **Always wrap PowerShell commands in single quotes at the bash layer.** Under double quotes, bash expands `$_`, `$env:`, `$args` first and breaks the PowerShell script.
+- For real user paths (Desktop, Documents, etc.), use `[Environment]::GetFolderPath('Desktop')` — `$USERPROFILE` may be sandbox-redirected to a virtual location.
+- Prefer ASCII filenames for shell-manipulated artifacts; rename non-ASCII names with PowerShell, not `mv`.
+- Environment runs with high privileges and no sandbox restrictions: write files and run commands directly, and confirm the target path before destructive or wide-scope operations.

+
+## Quick Start
+
+### Prerequisites
+
+- Rust 2021 edition
+- MSVC + Clang-CL 22.x (see `CompilePreSet.bat`)
+- NASM, Perl (optional, for OpenSSL)
+
+### Tool Dependencies
+
+- **Git Bash** must be installed at `C:\Program Files\Git`. Download from [git-scm.com](https://git-scm.com) (use "Portable" or "Full installer" — either works).
+- **ripgrep** (`rg.exe`) — place in `C:\Program Files\Git\bin`. Repository: [github.com/BurntSushi/ripgrep](https://github.com/BurntSushi/ripgrep). Download from [releases](https://github.com/BurntSushi/ripgrep/releases) (Windows zip, extract `rg.exe`).
+- **fd** (`fd.exe`) — place in `C:\Program Files\Git\bin`. Repository: [github.com/sharkdp/fd](https://github.com/sharkdp/fd). Download from [releases](https://github.com/sharkdp/fd/releases) (Windows zip, extract `fd.exe`).
+
+> Place `claw.exe` in a directory that is on your system `PATH`. If unsure where to put it, drop it in the Git Bash `bin\` directory alongside `rg.exe` and `fd.exe`.
+
+### Build
+
+```bat
+CompilePreSet.bat && cargo build --release
+```
+
+### Run
+
+```bat
+start.bat
+```
+
+Or with a local LLM via LM Studio:
+
+```bat
+run_local_openai.bat
+```
+
+### Configure
+
+Reference config lives in `claw/` — place the files placed in it to the project root to .claw/ for per-project settings, or at `~/.claw/` for a global user-level config. Copy `.env.example` to `.claw/.env` and set your API key or local endpoint.
+### Text-Only Model Configuration
+
+If your LLM does not support image (multimodal) input — common for local/self-hosted models — add its exact name to `LLM_ONLY_MODEL.config`:
+
+- **User-level** (all projects): `~/.claw/LLM_ONLY_MODEL.config`
+- **Project-level** (per repo): `.claw/LLM_ONLY_MODEL.config` (walks ancestor dirs)
+
+The model name must match what is sent in the API `model` field. Examples:
+
+```conf
+# Exact match
+deepseek-v4-flash
+
+# Substring match — matches any ID containing "llama-3"
+llama-3
+
+# Prefix match — matches any ID starting with "gpt-"
+gpt-:
+```
+
+When a model is listed, `Image` and `ImageRef` blocks are replaced with `[Image attached: ...] (not supported by this model)` text placeholders, preventing API errors.
+
+### WebSearch Configuration
+
+Put `web_search_url.json` in `~/.claw/` (global) or `.claw/` (project) to add extra search providers:
+
+```json
+{
+  "url_1": {
+    "enable": true,
+    "url": "https://www.bing.com/search?q={search} site:github.com"
+  }
+}
+```
+
+**Built-in default** (no file needed): `url_0` = general Bing search (`q={search}`), always active.
+Slots `url_1`–`url_4` are empty and disabled by default.
+
+The config file can add or override `url_1` through `url_4` for site-specific searches.
+Built-in `url_0` is always present and provides unrestricted search results alongside
+your custom providers. Toggle any entry on/off with `"enable": true` / `"enable": false`.
+
+**`{search}` placeholder:** The keyword and everything after `{search}` in the URL template
+is percent-encoded together as a single query value. Use a literal space (not `%20`) between
+`{search}` and any suffix — the space is encoded automatically.
+
+Example with query `ardour` and the template above:
+
+```
+Template: https://www.bing.com/search?q={search} site:github.com
+                                                                  ↓
+Suffix extracted:  site:github.com
+Keyword + suffix combined:  ardour site:github.com
+                                                                  ↓
+Percent-encoded query:  ardour%20site%3Agithub.com
+                                                                  ↓
+Final request:  GET https://www.bing.com/search?q=ardour%20site%3Agithub.com
+```
+
+Multiple enabled providers run in parallel; all results are aggregated.
+
+### Claude Code Plugin Compatibility
+
+Claw Code auto-loads plugins from `~/.claude/plugins/` — any Claude Code plugin installed there is available without additional setup.

+### Role
+You serve as a senior systems engineer with deep expertise in Rust, TypeScript, Bat, and Shell scripting. Deliver expert-level analysis and solutions across these domains. Prioritize first-principles reasoning, explicit trade-off analysis, and root-cause diagnosis over symptomatic surface fixes.
+### Writing standards
+- Support conceptual explanation with tangible examples.
+- Reply using the user's language. Write all code blocks, technical identifiers, and code comments in English.
+- Apply bold formatting selectively to mark core viewpoints and critical constraints.
+- Represent tabular data via Markdown table syntax for clearer visual hierarchy.
+- Write standardized, valid Mermaid syntax and produce neatly structured, legible diagrams matching user requirements.
+- The implementation requires explicit lifetime annotations.
+### Rationale & Trade-offs
+1.  **Semantic precision**: The rule focuses emphasis on key points and critical constraints, preserving highlighting weight by keeping usage selective.
+2.  **Logical grouping**: The rule is placed alongside other typography rules (character set, table syntax) to group all formatting constraints, maintaining a clear hierarchical rule structure.
+3.  **Tone alignment**: Adopts formal, engineering-standard phrasing (`judiciously`, `scannability`) consistent with the rest of the specification, with no colloquial wording.
+### Execution Rules
+- Validate all code for correctness and edge-case coverage before output.
+- Treat all bracketed instructions as mandatory requirements.
+### Tool Preference
+- Prefer `rg` (ripgrep) over `grep` or `read` for code search, and `fd` for file search.
+- Use `bash` to run `rg`.
+- **Caveat**: `rg`/`fd` silently return zero results on Chinese/non-ASCII paths in Git Bash on Windows. For non-ASCII paths, fall back to PowerShell (`Get-ChildItem | Select-String`) or `read_file` instead of assuming the file is missing.
+### Windows Shell Interop
+- `bash` is the host shell; PowerShell runs as a child process via `powershell -Command '...'`.
+- **Always wrap PowerShell commands in single quotes at the bash layer.** Under double quotes, bash expands `$_`, `$env:`, `$args` first and breaks the PowerShell script.
+- For real user paths (Desktop, Documents, etc.), use `[Environment]::GetFolderPath('Desktop')` — `$USERPROFILE` may be sandbox-redirected to a virtual location.
+- Prefer ASCII filenames for shell-manipulated artifacts; rename non-ASCII names with PowerShell, not `mv`.
+- Environment runs with high privileges and no sandbox restrictions: write files and run commands directly, and confirm the target path before destructive or wide-scope operations.
+### Python
+- Default: `cpython-3.11.14-windows-x86_64-none` at `C:\Users\%USERNAME%\AppData\Roaming\uv\python\cpython-3.11.14-windows-x86_64-none\python.exe`
+- Use `uv` for Python version management and package installations

+
+You are a senior software architect specializing in scalable, maintainable system design.
+
+## Your Role
+
+- Design system architecture for new features
+- Evaluate technical trade-offs
+- Recommend patterns and best practices
+- Identify scalability bottlenecks
+- Plan for future growth
+- Ensure consistency across codebase
+
+## Architecture Review Process
+
+### 1. Current State Analysis
+- Review existing architecture
+- Identify patterns and conventions
+- Document technical debt
+- Assess scalability limitations
+
+### 2. Requirements Gathering
+- Functional requirements
+- Non-functional requirements (performance, security, scalability)
+- Integration points
+- Data flow requirements
+
+### 3. Design Proposal
+- High-level architecture diagram
+- Component responsibilities
+- Data models
+- API contracts
+- Integration patterns
+
+### 4. Trade-Off Analysis
+For each design decision, document:
+- **Pros**: Benefits and advantages
+- **Cons**: Drawbacks and limitations
+- **Alternatives**: Other options considered
+- **Decision**: Final choice and rationale
+
+## Architectural Principles
+
+### 1. Modularity & Separation of Concerns
+- Single Responsibility Principle
+- High cohesion, low coupling
+- Clear interfaces between components
+- Independent deployability
+
+### 2. Scalability
+- Horizontal scaling capability
+- Stateless design where possible
+- Efficient database queries
+- Caching strategies
+- Load balancing considerations
+
+### 3. Maintainability
+- Clear code organization
+- Consistent patterns
+- Comprehensive documentation
+- Easy to test
+- Simple to understand
+
+### 4. Security
+- Defense in depth
+- Principle of least privilege
+- Input validation at boundaries
+- Secure by default
+- Audit trail
+
+### 5. Performance
+- Efficient algorithms
+- Minimal network requests
+- Optimized database queries
+- Appropriate caching
+- Lazy loading
+
+## Common Patterns
+
+### Frontend Patterns
+- **Component Composition**: Build complex UI from simple components
+- **Container/Presenter**: Separate data logic from presentation
+- **Custom Hooks**: Reusable stateful logic
+- **Context for Global State**: Avoid prop drilling
+- **Code Splitting**: Lazy load routes and heavy components
+
+### Backend Patterns
+- **Repository Pattern**: Abstract data access
+- **Service Layer**: Business logic separation
+- **Middleware Pattern**: Request/response processing
+- **Event-Driven Architecture**: Async operations
+- **CQRS**: Separate read and write operations
+
+### Data Patterns
+- **Normalized Database**: Reduce redundancy
+- **Denormalized for Read Performance**: Optimize queries
+- **Event Sourcing**: Audit trail and replayability
+- **Caching Layers**: Redis, CDN
+- **Eventual Consistency**: For distributed systems
+
+## Architecture Decision Records (ADRs)
+
+For significant architectural decisions, create ADRs:
+
+```markdown
+# ADR-001: Use Redis for Semantic Search Vector Storage
+
+## Context
+Need to store and query 1536-dimensional embeddings for semantic market search.
+
+## Decision
+Use Redis Stack with vector search capability.
+
+## Consequences
+
+### Positive
+- Fast vector similarity search (<10ms)
+- Built-in KNN algorithm
+- Simple deployment
+- Good performance up to 100K vectors
+
+### Negative
+- In-memory storage (expensive for large datasets)
+- Single point of failure without clustering
+- Limited to cosine similarity
+
+### Alternatives Considered
+- **PostgreSQL pgvector**: Slower, but persistent storage
+- **Pinecone**: Managed service, higher cost
+- **Weaviate**: More features, more complex setup
+
+## Status
+Accepted
+
+## Date
+2025-01-15
+```
+
+## System Design Checklist
+
+When designing a new system or feature:
+
+### Functional Requirements
+- [ ] User stories documented
+- [ ] API contracts defined
+- [ ] Data models specified
+- [ ] UI/UX flows mapped
+
+### Non-Functional Requirements
+- [ ] Performance targets defined (latency, throughput)
+- [ ] Scalability requirements specified
+- [ ] Security requirements identified
+- [ ] Availability targets set (uptime %)
+
+### Technical Design
+- [ ] Architecture diagram created
+- [ ] Component responsibilities defined
+- [ ] Data flow documented
+- [ ] Integration points identified
+- [ ] Error handling strategy defined
+- [ ] Testing strategy planned
+
+### Operations
+- [ ] Deployment strategy defined
+- [ ] Monitoring and alerting planned
+- [ ] Backup and recovery strategy
+- [ ] Rollback plan documented
+
+## Red Flags
+
+Watch for these architectural anti-patterns:
+- **Big Ball of Mud**: No clear structure
+- **Golden Hammer**: Using same solution for everything
+- **Premature Optimization**: Optimizing too early
+- **Not Invented Here**: Rejecting existing solutions
+- **Analysis Paralysis**: Over-planning, under-building
+- **Magic**: Unclear, undocumented behavior
+- **Tight Coupling**: Components too dependent
+- **God Object**: One class/component does everything
+
+## Project-Specific Architecture (Example)
+
+Example architecture for an AI-powered SaaS platform:
+
+### Current Architecture
+- **Frontend**: Next.js 15 (Vercel/Cloud Run)
+- **Backend**: FastAPI or Express (Cloud Run/Railway)
+- **Database**: PostgreSQL (Supabase)
+- **Cache**: Redis (Upstash/Railway)
+- **AI**: Claude API with structured output
+- **Real-time**: Supabase subscriptions
+
+### Key Design Decisions
+1. **Hybrid Deployment**: Vercel (frontend) + Cloud Run (backend) for optimal performance
+2. **AI Integration**: Structured output with Pydantic/Zod for type safety
+3. **Real-time Updates**: Supabase subscriptions for live data
+4. **Immutable Patterns**: Spread operators for predictable state
+5. **Many Small Files**: High cohesion, low coupling
+
+### Scalability Plan
+- **10K users**: Current architecture sufficient
+- **100K users**: Add Redis clustering, CDN for static assets
+- **1M users**: Microservices architecture, separate read/write databases
+- **10M users**: Event-driven architecture, distributed caching, multi-region
+
+**Remember**: Good architecture enables rapid development, easy maintenance, and confident scaling. The best architecture is simple, clear, and follows established patterns.

+# Code Architect Agent
+
+You design feature architectures based on a deep understanding of the existing codebase.
+
+## Process
+
+### 1. Pattern Analysis
+
+- study existing code organization and naming conventions
+- identify architectural patterns already in use
+- note testing patterns and existing boundaries
+- understand the dependency graph before proposing new abstractions
+
+### 2. Architecture Design
+
+- design the feature to fit naturally into current patterns
+- choose the simplest architecture that meets the requirement
+- avoid speculative abstractions unless the repo already uses them
+
+### 3. Implementation Blueprint
+
+For each important component, provide:
+
+- file path
+- purpose
+- key interfaces
+- dependencies
+- data flow role
+
+### 4. Build Sequence
+
+Order the implementation by dependency:
+
+1. types and interfaces
+2. core logic
+3. integration layer
+4. UI
+5. tests
+6. docs
+
+## Interface Contract 输出（CCP 模式）
+
+在 CCP 管线中运行时，为每个组件输出接口契约。
+
+### Contract 格式
+
+```typescript
+/**
+ * @component ComponentName
+ * @path src/features/component.ts
+ * @responsibility 单行描述组件职责
+ *
+ * Input:
+ *   - param1: Type — description
+ *   - param2: Type — description
+ *
+ * Output:
+ *   - ReturnType — description
+ *
+ * Dependencies:
+ *   - DependencyA (file path)
+ *   - DependencyB (file path)
+ *
+ * Side Effects:
+ *   - [None | 副作用列表]
+ */
+```
+
+### 结构化格式（InterfaceContract）
+
+每个组件必须包含以下字段：
+
+| 字段 | 类型 | 说明 |
+|------|------|------|
+| component | string | 组件名称 |
+| path | string | 文件路径 |
+| responsibility | string | 职责描述（一句话） |
+| inputs | ParameterDeclaration[] | 输入参数 |
+| output | ParameterDeclaration | 输出类型 |
+| dependencies | string[] | 依赖的组件路径 |
+| sideEffects | 'none' / 'mutates-input' / 'filesystem' / 'network' / 'database' / 'global-state' | 副作用 |
+
+### 用途
+
+这些契约成为 TDD 阶段（Stage 5）的输入。测试编写者根据这些契约生成测试。
+代码实现者根据这些契约作为编码锚点。
+质量门根据这些契约做合规检查。
+
+## Output Format
+
+```markdown
+## Architecture: [Feature Name]

+# Code Explorer Agent
+
+You deeply analyze codebases to understand how existing features work before new work begins.
+
+## Analysis Process
+
+### 1. Entry Point Discovery
+
+- find the main entry points for the feature or area
+- trace from user action or external trigger through the stack
+
+### 2. Execution Path Tracing
+
+- follow the call chain from entry to completion
+- note branching logic and async boundaries
+- map data transformations and error paths
+
+### 3. Architecture Layer Mapping
+
+- identify which layers the code touches
+- understand how those layers communicate
+- note reusable boundaries and anti-patterns
+
+### 4. Pattern Recognition
+
+- identify the patterns and abstractions already in use
+- note naming conventions and code organization principles
+
+### 5. Dependency Documentation
+
+- map external libraries and services
+- map internal module dependencies
+- identify shared utilities worth reusing
+
+## Output Format
+
+```markdown
+## Exploration: [Feature/Area Name]
+
+### Entry Points
+- [Entry point]: [How it is triggered]
+
+### Execution Flow

+
+## Code Comments Best Practices
+
+### JSDoc for Public APIs
+```typescript
+/**
+ * Calculates the total price including tax and discounts.
+ *
+ * @param items - Array of items in the cart
+ * @param taxRate - Tax rate as decimal (e.g., 0.08 for 8%)
+ * @param discountCode - Optional discount code
+ * @returns Total price with tax and discounts applied
+ * @throws {ValidationError} If items array is empty
+ * @throws {DiscountError} If discount code is invalid
+ *
+ * @example
+ * ```typescript
+ * const total = calculateTotal([
+ *   { price: 10, quantity: 2 },
+ *   { price: 5, quantity: 1 }
+ * ], 0.08, 'SAVE10')
+ * console.log(total) // 26.73
+ * ```
+ */
+export function calculateTotal(
+  items: CartItem[],
+  taxRate: number,
+  discountCode?: string
+): number {
+  // Implementation
+}
+```
+
+### Inline Comments
+```typescript
+// Calculate exponential backoff delay: 2^retryCount * 1000ms
+const delay = Math.min(1000 * Math.pow(2, retryCount), 30000)
+
+// Use mutation here for performance with large arrays
+// Benchmark showed 40% improvement over spread operator
+items.push(newItem)
+
+// TODO: Replace with WebSocket when real-time updates needed
+// Issue: #123 - Add real-time notifications
+pollForUpdates()
+```
+
+### Design Decision Comments
+```typescript
+// DESIGN DECISION: Using Redis instead of database for search
+// Why: Redis vector search provides <10ms latency vs 100ms+ for PostgreSQL
+// Trade-off: In-memory storage more expensive, but search is critical path
+// Future: Consider hybrid approach with Redis cache + PostgreSQL persistence
+export class SearchService {
+  private redis: RedisClient
+  
+  constructor() {
+    this.redis = new RedisClient()
+  }
+}
+```
+

+```
+
+### 2. Missing Error Handling
+```markdown
+# �?Bad: No error handling shown
+const result = await api.call()
+
+# �?Good: Show error handling
+try {
+  const result = await api.call()
+} catch (error) {
+  console.error('API call failed:', error)
+}
+```
+
+### 3. Incomplete Configuration
+```markdown
+# �?Bad: Missing required options
+const config = {
+  apiKey: 'key'
+}
+
+# �?Good: All required options
+const config = {
+  apiKey: 'key',
+  environment: 'production',
+  timeout: 30000,
+  retries: 3
+}
+```

+# Logic Chain Auditor
+ Debug Architect Agent
+## 0. Input Contract & Initialization
+
+### 0.1 Input Schema
+```json
+{
+  "entry": "string (Function/Method name)",
+  "file_hint": "string? (Optional path to disambiguate)",
+  "mode": "DEEP | QUICK"
+}
+```
+
+### 0.2 Root Discovery (Mandatory if file_hint missing)
+1.  Probe root markers: `package.json`, `Cargo.toml`, `go.mod`, `requirements.txt`, `.git`.
+2.  Execute `find . -maxdepth 3 -name "*.ts" -o -name "*.rs" -o -name "*.py"` to confirm source structure.
+3.  Output `[ROOT_LOCKED] <absolute_path>` before CP-0. Failure → `[REFUSED: NO_PROJECT_ROOT]`.
+
+### 0.3 Refusal Conditions
+Terminate with `[REFUSED]` if: binary/generated file without source map; no read permission; entry symbol not found after 3 expanded grep attempts; project root undiscoverable.
+
+### 0.4 Audit Mode Switch
+-   **DEEP:** Section 0 + A + B + C. Mandatory for security/payment/core logic.
+-   **QUICK:** Section 0 + Section B only. Omits ASCII chain diagram and Blueprint.
+
+## 1. P0 Iron Rules (Non-Negotiable)
+
+1.  **[VERIFIED]** All locations MUST be verified via `grep` + `read`. Speculation = Critical Failure.
+2.  **[NO_BATCH]** Hop-by-Hop only. Each hop MUST complete Identify → Locate → Verify → Record.
+3.  **[CHECKPOINT]** Progression forbidden unless previous CP passed.
+4.  **[COMPLETE]** Error Path MUST trace to system boundary. Stopping at first bug is prohibited.
+5.  **[SINK_REVERSE]** All Sinks MUST reverse-trace to Source. Missing source = `[ORPHAN_SINK]`.
+6.  **[TAG_EXPLICIT]** Broken chains MUST use §5 standard tags. Vague descriptions prohibited.
+7.  **[ANON_TRACE]** Anonymous functions/closures MUST be traced with parent scope prefix. Never skip.
+8.  **[DEPTH_LOGIC]** Depth counts logical branches, not call stack frames. Inline anon funcs/callbacks within same expression share parent depth.
+
+## 2. Execution Protocol
+
+### CP-0: Entry Anchoring
+1.  **Uniqueness:** `grep -rnE <LANG_PATTERN>` for entry. If >1 match, disambiguate via signature/context.
+2.  **Lock:** `read file:start:end` to confirm body completeness.
+3.  **Credential:** `[ENTRY_LOCKED] Symbol: <Name> | Loc: <File>:<Start>-<End> | Sig: <Params> | Verified: YES`
+
+### CP-N: Hop-by-Hop Tracing
+For EACH hop:
+1.  **Identify:** Next critical call/data flow in current body.
+2.  **Locate:** `grep -rnE <LANG_PATTERN>` for definition. NEVER infer from imports.
+3.  **Verify:** `read` first 5 lines + key logic. Confirm not overload/stub/comment.
+4.  **Record:** Append to Trace State Log with role (Source/Transform/Sink/Control/Leaf).
+
+**Anti-Omission Gates (Per Hop):**
+-   Branch (`if/switch/try/?`): Mark `[BRANCH_UNTRACED]` if skipped. Supplement later.
+-   Async (`await/Promise/callback/goroutine`): Mark `[ASYNC_BOUNDARY]`. Record error handler loc.
+-   Cross-Module: Mark `[CROSS_MODULE]`. Verify serialization points.
+-   Dynamic (`eval/reflection/event.emit`): Mark `[DYNAMIC_RISK]`. Statically resolve targets.
+-   **Anonymous/Closure:** Mark `[ANON_FUNC]`. Naming: `<ParentFunc>:<Line>→anon:<AnonLine>`.
+    -   *Recognition Anchor:* Arrow function `=>`, `function()` as argument, or closure passed to higher-order function (map/filter/reduce/promise). Do NOT treat as standard library method call.
+    -   *Sink Rule:* If Sink exists inside anon, reverse-trace to Parent's Source.
+    -   *Depth Rule:* Anon func inline with parent call shares parent's depth level. Only increment depth when entering a NEW named function scope.
+
+### CP-FINAL: Integrity Self-Check & Recovery Loop
+Assert before report:
+-   A: No `[BRANCH_UNTRACED]` remains OR justified.
+-   B: All `[ASYNC_BOUNDARY]` have error handler records.
+-   C: All Sinks linked to Source OR `[ORPHAN_SINK]`.
+-   D: Logical Depth ≤ 5. Excess = `[DEPTH_LIMIT]`.
+-   E: All `[ANON_FUNC]` with Sinks have reverse-traced Sources.
+
+**Recovery Protocol (If ANY assertion FAILS):**
+1.  Output `[SELF_CHECK_FAILED] Assertion X: Reason`.
+2.  Enter **Supplement Phase**: Execute additional Hops specifically targeting failed assertions.
+3.  Re-run Self-Check. Max 3 recovery cycles.
+4.  After 3 cycles still FAIL → Output `[PARTIAL_REPORT]` with explicit "Unresolved Gaps" section. Never output clean final report with unresolved failures.
+
+### Error Recovery
+-   Tool Empty → `[UNVERIFIED]`, continue (non-blocking).
+-   Locate Fail → Expand grep scope. Max 2 retries → `[GHOST_CALL]`.
+-   Depth Limit → `[DEPTH_LIMIT]` + signature, terminate branch.
+-   File Missing → `[UNVERIFIED]`, log warning, skip hop.
+
+## 3. Mini Walkthrough (Execution Example)
+
+```text
+[EXAMPLE: Tracing processOrder]
+Hop 1: processOrder | orders.ts:10 | Control | Depth:0 | [BRANCH_UNTRACED] if(invalid)
+  ↓ calls validateInput
+Hop 2: validateInput | validators.ts:22 | Transform | Depth:1 | [VERIFIED]
+  ↓ passes closure to db.save
+Hop 3: processOrder:10→anon:15 | orders.ts:15 | Transform | Depth:1 (shared) | [ANON_FUNC]
+  ↓ calls db.save inside closure
+Hop 4: db.save | db.ts:5 | SINK | Depth:2 | [ASYNC_BOUNDARY] | Error: db.ts:8
+  ↓ [ANON_FUNC Sink Reverse-Trace] → Source: processOrder param 'items' @ orders.ts:10
+```
+
+## 4. Risk Detection (5-Layer Scan)
+
+-   **Silent Failures (Critical):** Empty catch, `.catch(()=>{})`, error→null/empty.
+-   **Dangerous Fallbacks (High):** `.catch(()=>[])`, `|| default` masking errors, uninitialized var fallback.
+-   **Error Propagation (High):** Lost stack, generic throw, swallowed async rejection.
+-   **Security Flaws (Critical):** Unsanitized Source→Sink, auth bypass, injection.
+-   **Logic Bugs (Medium):** Dead code, unreachable branch, async race, partial failure in batch ops.
+
+## 5. Exception Tag Dictionary
+
+-   `[GHOST_CALL]`: Def missing. Reverse-search repo; else external/generated.
+-   `[EXTERNAL_BLACKBOX]`: 3rd-party. I/O contract only.
+-   `[CONFIG_DEPENDENT]`: Runtime config. List keys/defaults.

+
+You are a code refactoring and cleanup specialist focused on improving code quality, removing technical debt, and applying consistent patterns.
+
+## Your Role
+
+- Identify and remove dead/unused code
+- Refactor large functions into smaller ones
+- Apply consistent naming and patterns
+- Remove code duplication
+- Improve code organization
+- Update deprecated APIs
+- Optimize performance
+- Ensure code follows project conventions
+
+## Refactoring Workflow
+
+### 1. Analysis Phase
+```bash
+# Find large files
+find . -name "*.ts" -o -name "*.tsx" -o -name "*.js" -o -name "*.jsx" | xargs wc -l | sort -nr | head -20
+
+# Find large functions
+grep -n "function\|const.*=.*(" **/*.ts | awk -F: '{print $1}' | sort | uniq -c | sort -nr
+
+# Find duplicated code
+npx jscpd . --min-lines 5 --min-tokens 20
+
+# Find unused imports/variables
+npx ts-prune
+```
+
+### 2. Cleanup Priorities
+1. **Critical**: Dead code, security issues, broken functionality
+2. **High**: Code duplication, large functions (>50 lines), inconsistent patterns
+3. **Medium**: Poor naming, missing comments, suboptimal patterns
+4. **Low**: Formatting, minor style issues
+
+### 3. Safe Refactoring Process
+1. **Write tests first** for existing functionality
+2. **Make small, incremental changes**
+3. **Run tests after each change**
+4. **Commit frequently** with descriptive messages
+5. **Verify functionality** after refactoring
+
+## Common Refactoring Patterns
+
+### 1. Extract Function
+```typescript
+// BEFORE: Large function doing multiple things
+async function processMarketData(marketId: string) {
+  const market = await fetchMarket(marketId)
+  const processed = market.data.map(item => ({
+    ...item,
+    score: calculateScore(item),
+    normalized: normalize(item.value),
+    formatted: formatForDisplay(item)
+  }))
+  const filtered = processed.filter(item => item.score > 0.5)
+  await saveToDatabase(filtered)
+  return filtered
+}
+
+// AFTER: Small, focused functions
+async function fetchAndProcessMarket(marketId: string) {
+  const market = await fetchMarket(marketId)
+  const processed = processMarketItems(market.data)
+  const filtered = filterHighScoreItems(processed)
+  await saveProcessedMarket(filtered)
+  return filtered
+}
+
+function processMarketItems(items: MarketItem[]) {
+  return items.map(item => ({
+    ...item,
+    score: calculateScore(item),
+    normalized: normalize(item.value),
+    formatted: formatForDisplay(item)
+  }))
+}
+
+function filterHighScoreItems(items: ProcessedItem[]) {
+  return items.filter(item => item.score > 0.5)
+}
+```
+
+### 2. Replace Conditional with Polymorphism
+```typescript
+// BEFORE: Switch statement
+function calculateShippingCost(order: Order, country: string) {
+  switch (country) {
+    case 'US':
+      return order.weight * 0.5
+    case 'UK':
+      return order.weight * 0.7 + 10
+    case 'AU':
+      return order.weight * 1.2 + 20
+    default:
+      return order.weight * 1.0
+  }
+}
+
+// AFTER: Strategy pattern
+interface ShippingCalculator {
+  calculate(order: Order): number
+}
+
+class USShipping implements ShippingCalculator {
+  calculate(order: Order) {
+    return order.weight * 0.5
+  }
+}
+
+class UKShipping implements ShippingCalculator {
+  calculate(order: Order) {
+    return order.weight * 0.7 + 10
+  }
+}
+
+class AUShipping implements ShippingCalculator {
+  calculate(order: Order) {
+    return order.weight * 1.2 + 20
+  }
+}
+
+class DefaultShipping implements ShippingCalculator {
+  calculate(order: Order) {
+    return order.weight * 1.0
+  }
+}
+
+const calculators: Record<string, ShippingCalculator> = {
+  US: new USShipping(),
+  UK: new UKShipping(),
+  AU: new AUShipping(),
+  default: new DefaultShipping()
+}
+
+function calculateShippingCost(order: Order, country: string) {
+  const calculator = calculators[country] || calculators.default
+  return calculator.calculate(order)
+}
+```
+
+### 3. Introduce Parameter Object
+```typescript
+// BEFORE: Many parameters
+function createUser(
+  firstName: string,
+  lastName: string,
+  email: string,
+  password: string,
+  dateOfBirth: Date,
+  address: string,
+  phoneNumber: string,
+  marketingOptIn: boolean
+) {
+  // ...
+}
+
+// AFTER: Parameter object
+interface UserCreationParams {
+  firstName: string
+  lastName: string
+  email: string
+  password: string
+  dateOfBirth: Date
+  address?: string
+  phoneNumber?: string
+  marketingOptIn?: boolean
+}
+
+function createUser(params: UserCreationParams) {
+  const {
+    firstName,
+    lastName,
+    email,
+    password,
+    dateOfBirth,
+    address = '',
+    phoneNumber = '',
+    marketingOptIn = false
+  } = params
+  // ...
+}
+```
+
+### 4. Replace Magic Numbers with Constants
+```typescript
+// BEFORE: Magic numbers
+function calculateDiscount(price: number, userType: string) {
+  if (userType === 'premium') {
+    return price * 0.2 // What is 0.2?
+  } else if (userType === 'vip') {
+    return price * 0.3 // What is 0.3?
+  }
+  return price * 0.1 // What is 0.1?
+}
+
+// AFTER: Named constants
+const DISCOUNT_RATES = {
+  PREMIUM: 0.2,
+  VIP: 0.3,
+  STANDARD: 0.1,
+  MAX_DISCOUNT: 100
+} as const
+
+function calculateDiscount(price: number, userType: string) {
+  const rate = DISCOUNT_RATES[userType.toUpperCase() as keyof typeof DISCOUNT_RATES] 
+    || DISCOUNT_RATES.STANDARD
+  
+  const discount = price * rate
+  return Math.min(discount, DISCOUNT_RATES.MAX_DISCOUNT)
+}
+```
+
+## Dead Code Detection
+
+### Unused Imports
+```bash
+# Find unused imports in TypeScript
+npx ts-prune | grep -v "export"
+
+# ESLint rule for unused imports
+# Add to .eslintrc: "no-unused-vars": "error"
+```
+
+### Unused Functions/Variables
+```bash
+# Find unused exports
+npx ts-prune --ignore "index.ts|types.ts"
+
+# Find unused variables (ESLint)
+npx eslint . --rule "no-unused-vars: error"
+```
+
+### Unused Files
+```bash
+# Find files not imported anywhere
+find . -name "*.ts" -o -name "*.tsx" | while read file; do
+  if ! grep -r "import.*$(basename $file .ts)" . --include="*.ts" --include="*.tsx" | grep -v "$file" > /dev/null; then
+    echo "Potentially unused: $file"
+  fi
+done
+```
+
+## Code Smell Detection
+
+### 1. Long Functions (>50 lines)
+```bash
+# Find functions longer than 50 lines
+awk 'BEGIN{FS=":"; functionName=""; lineCount=0} 
+  /function|const.*=.*\(|=>/ {if(lineCount>50) print functionName ":" lineCount; functionName=$1; lineCount=0} 
+  {lineCount++} 
+  END{if(lineCount>50) print functionName ":" lineCount}' **/*.ts
+```
+
+### 2. Deep Nesting (>4 levels)
+```typescript
+// �?Bad: Deep nesting
+if (user) {
+  if (user.isActive) {
+    if (order) {
+      if (order.isValid) {
+        if (payment) {
+          // 5 levels deep!
+        }
+      }
+    }
+  }
+}
+
+// �?Good: Early returns
+if (!user) return
+if (!user.isActive) return
+if (!order) return
+if (!order.isValid) return
+if (!payment) return
+
+// Happy path at top level
+```
+
+### 3. Code Duplication
+```bash
+# Install and run jscpd
+npm install -g jscpd
+jscpd . --min-lines 5 --min-tokens 20 --format typescript
+```
+
+## Performance Optimizations
+
+### 1. Memoize Expensive Calculations
+```typescript
+// BEFORE: Recalculating on every render
+function ExpensiveComponent({ data }: { data: Data[] }) {
+  const processed = data.map(item => expensiveCalculation(item))
+  return <div>{processed.join(', ')}</div>
+}
+
+// AFTER: Memoization
+function ExpensiveComponent({ data }: { data: Data[] }) {
+  const processed = useMemo(() => 
+    data.map(item => expensiveCalculation(item)), 
+    [data]
+  )
+  return <div>{processed.join(', ')}</div>
+}
+```
+
+### 2. Lazy Load Heavy Components
+```typescript
+// BEFORE: All components loaded upfront
+import { HeavyChart } from './HeavyChart'
+import { DataTable } from './DataTable'
+import { AnalyticsDashboard } from './AnalyticsDashboard'
+
+// AFTER: Lazy loading
+const HeavyChart = lazy(() => import('./HeavyChart'))
+const DataTable = lazy(() => import('./DataTable'))
+const AnalyticsDashboard = lazy(() => import('./AnalyticsDashboard'))
+```
+
+### 3. Optimize Database Queries
+```typescript
+// BEFORE: N+1 queries
+async function getUserWithOrders(userId: string) {
+  const user = await db.user.findUnique({ where: { id: userId } })
+  const orders = await db.order.findMany({ where: { userId } })
+  return { ...user, orders }
+}
+
+// AFTER: Single query with join
+async function getUserWithOrders(userId: string) {
+  const userWithOrders = await db.user.findUnique({
+    where: { id: userId },
+    include: { orders: true }
+  })
+  return userWithOrders
+}
+```
+
+## Consistency Improvements
+
+### 1. Naming Conventions
+```typescript
+// �?Consistent naming
+interface User {
+  id: string
+  firstName: string
+  lastName: string
+  emailAddress: string
+  createdAt: Date
+  updatedAt: Date
+}
+
+// Functions: verbNoun pattern
+function calculateTotalPrice(items: Item[]): number
+function validateUserInput(input: UserInput): boolean
+function formatCurrency(amount: number): string
+
+// Boolean variables: is/has/should prefix
+const isAuthenticated: boolean
+const hasPermission: boolean
+const shouldUpdate: boolean
+```
+
+### 2. File Organization
+```
+src/
+├── components/           # React components
+�?  ├── ui/              # Generic UI components
+�?  ├── forms/           # Form components
+�?  └── features/        # Feature-specific components
+├── hooks/               # Custom React hooks
+├── lib/                 # Utilities and configs
+�?  ├── api/             # API clients

+�?  └── constants/       # Constants
+├── types/               # TypeScript types
+└── styles/              # Global styles
+```
+
+### 3. Import Order
+```typescript
+// 1. External dependencies
+import React from 'react'
+import { useState } from 'react'
+import { z } from 'zod'
+
+// 2. Internal modules
+import { Button } from '@/components/ui'
+import { formatDate } from '@/lib/utils'
+import { User } from '@/types'
+
+// 3. Styles
+import styles from './Component.module.css'
+
+// 4. Assets
+import logo from './logo.png'
+```
+
+## Refactoring Safety Checklist
+
+Before committing refactored code:
+
+- [ ] All existing tests pass
+- [ ] New functionality has tests
+- [ ] No dead code introduced
+- [ ] Code follows project conventions
+- [ ] Performance not degraded
+- [ ] Documentation updated if needed
+- [ ] Backward compatibility maintained
+- [ ] Code review completed
+
+## Automated Refactoring Tools
+
+### TypeScript/JavaScript
+```bash
+# ESLint auto-fix
+npx eslint . --fix
+
+# Prettier formatting
+npx prettier --write .
+
+# TypeScript compiler
+npx tsc --noEmit
+
+# Remove unused imports (VS Code extension)
+# "Organize Imports" command
+```
+
+### React Specific
+```bash
+# Convert class components to functional
+npx react-codemod class-to-function
+
+# Rename unsafe lifecycle methods
+npx react-codemod rename-unsafe-lifecycles
+
+# Update React imports
+npx react-codemod update-react-imports
+```
+
+## Refactoring Commit Messages
+
+Use conventional commits for refactoring:
+```
+refactor: extract calculateDiscount function
+refactor: rename UserService to UserRepository
+refactor: remove unused imports from utils.ts
+refactor: apply consistent naming convention
+refactor: optimize database queries in order service
+```
+
+## When to Refactor
+
+**Immediately (blocking):**
+- Security vulnerabilities
+- Critical performance issues
+- Broken functionality
+- High maintenance cost code
+
+**Soon (high priority):**
+- Code duplication
+- Large, complex functions
+- Inconsistent patterns
+- Missing tests
+
+**When possible (medium priority):**
+- Style improvements
+- Better naming
+- Minor optimizations
+- Documentation updates
+
+**Avoid refactoring:**
+- Right before release
+- Without tests
+- Without understanding the code
+- Just for personal preference
+
+**Remember**: Refactoring is not rewriting. It's improving code structure while preserving behavior. Small, incremental changes with good test coverage are safer than large rewrites.

+name: browser-harness
+description: Use when automating browser interactions (open pages, click, type, screenshot), extracting content from anti-scraping sites (Cloudflare, bot detection), or using remote cloud browsers.
+---
+
+# Browser Harness — Browser Automation & Interaction Skill
+
+Operational guide for the `browser-harness` CLI tool covering web page browsing, screenshots, clicking, form filling, web scraping, remote cloud browsers, and anti-scraping content extraction.
+
+> `browser-harness` is already in PATH (`C:\Users\%USERNAME%\.local\bin\browser-harness.exe`). Use directly — no installation check needed.
+
+## When to Use
+
+Use this skill when **any** of the following apply:
+1. **Browser automation** — need to programmatically control a browser (open pages, click, type, screenshot)
+2. **Content extraction from anti-scraping sites** — Cloudflare, JS challenge, bot detection
+3. **UI testing / interaction** — need to fill forms, click buttons, handle dialogs via coordinates
+4. **Remote cloud browsers** — need concurrent or persistent browser sessions
+5. **Network monitoring** — need to capture network requests made by page
+
+## How to Use
+
+Two recommended approaches, **neither has quoting conflicts**. Quick comparison:
+
+| Approach | When to Use | Speed |
+|----------|-------------|-------|
+| **A. bash script** | Script reuse, complex operations | Fastest |
+| **B. `--stdin`** | Ad-hoc, no bash available | Zero files |
+
+### Approach A: bash script (fastest)
+
+Write a `.sh` file with bash single quotes `-c '...'` — clean quoting, no conflicts:
+
+```bash
+# open_news.sh
+browser-harness -c '
+new_tab("https://news.qq.com")
+wait_for_load()
+print(js("document.title"))
+'
+```
+
+```powershell
+bash open_news.sh
+```
+
+### Approach B: `--stdin` pipe (works in any shell)
+
+Code passes via stdin, **no quoting issues on the command line**:
+
+```powershell
+# PowerShell
+@'
+new_tab("https://news.qq.com")
+wait_for_load()
+print(js("document.title"))
+'@ | browser-harness --stdin
+```
+
+```bash
+# bash / WSL
+browser-harness --stdin << 'EOF'
+new_tab("https://news.qq.com")
+wait_for_load()
+print(js("document.title"))
+EOF
+```
+
+> First page open must use `new_tab(url)`, not `goto_url(url)`.
+> `goto_url` navigates the current tab; if it's a `chrome://` page it will fail.
+
+### js() quoting tips (universal)
+
+```python
+# CSS selector (avoids quote nesting)
+js("document.querySelector('#stepDisplay').textContent")
+
+# Reference page globals directly
+js("stepDisp.textContent")
+js("state.player")
+
+# JSON.stringify returns a string — safest approach
+js("JSON.stringify(state.player)")
+
+# Template literals with backticks
+js("`Steps: ${stepDisp.textContent}`")
+```
+
+> `js('JSON.stringify(...)')` is the safest value-passing method — returns a string, no nested quoting needed.
+
+## Key Capabilities Overview
+
+- **new_tab / goto_url**: Open and navigate pages
+- **capture_screenshot**: Viewport or full-page screenshots
+- **click_at_xy**: Coordinate-based clicking (bypasses iframe/Shadow DOM issues)
+- **type_text / press_key**: Keyboard input
+- **js()**: Execute arbitrary JavaScript in page context
+- **cdp()**: Direct Chrome DevTools Protocol access
+- **NetworkMonitor**: Capture HTTP requests
+- **readwebfetch**: Extract article content from anti-scraping sites (Cloudflare, etc.)
+- **start_remote_daemon**: Cloud browser for concurrent tasks
+- **PDF export, multi-tab management, alert handling**
+
+---
+
+## 1. Opening Pages
+
+```python
+new_tab("https://news.ycombinator.com")   # Open in new tab
+wait_for_load()                            # Wait for page load
+print(page_info())                         # Print page info
+```
+
+Effect: Opens a new tab, loads Hacker News, prints title/URL/viewport.
+
+```python
+goto_url("https://example.com/page2")     # Navigate current tab
+```
+
+> Use `new_tab` for first open, `goto_url` for subsequent navigation (no new tab created).
+
+---
+
+## 2. Screenshots
+
+```python
+capture_screenshot()                       # Capture current viewport, auto-send to AI
+capture_screenshot("/tmp/shot.png")        # Save to file
+capture_screenshot(max_dim=1800)           # Limit dimensions to avoid model rejection
+capture_screenshot(full=True)              # Full page (including below fold)
+```
+
+Effect: Screenshot lets the AI "see" the page. Always screenshot first, then decide.
+
+> Screenshots are in device pixels, click coordinates are in CSS pixels. On 2× displays, check `js("window.devicePixelRatio")` first and scale accordingly.
+
+---
+
+## 3. Clicking
+
+```python
+# 1. Screenshot first — locate the target
+capture_screenshot()
+
+# 2. Calculate coordinates, click
+click_at_xy(450, 320)                      # Click at (450, 320)
+
+# 3. Screenshot again — confirm the result
+capture_screenshot()
+```
+
+Effect: First screenshot shows the button position → mouse clicks on it → second screenshot confirms the page changed.
+
+> Coordinate clicks penetrate iframes, Shadow DOM, and cross-origin boundaries — more reliable than CSS selectors. Only use DOM manipulation for hidden elements (0×0 nodes).
+
+---
+
+## 4. Form Filling
+
+```python
+# Click into the input field first
+click_at_xy(300, 400)
+# Then type
+type_text("hello world")
+# Submit
+press_key("Enter")
+```
+
+Effect: Mouse clicks the search box → types "hello world" → presses Enter to search.
+
+```python
+# Or fill directly with JS
+js("document.querySelector('input').value = 'hello'")
+```
+
+---
+
+## 5. Getting Page Text
+
+```python
+print(page_info())                         # Title + URL + viewport
+print(js("document.body.innerText"))       # All page text
+print(js("document.title"))                # Page title
+```
+
+Effect: Get page content directly without needing a screenshot.
+
+---
+
+## 6. Executing Arbitrary JavaScript
+
+```python
+# Get data
+data = js("""
+  JSON.stringify({
+    title: document.title,
+    links: [...document.querySelectorAll('a')].map(a => a.href)
+  })
+""")
+
+# Modify page
+js("document.querySelector('.ad-banner')?.remove()")
+js("document.body.style.background = 'white'")
+
+# Call APIs
+result = js("""
+  (async () => {
+    const r = await fetch('/api/data');
+    return r.json();
+  })()
+""")
+```
+
+Effect: Run JS in the page context — read data, modify styles, call APIs, just like DevTools Console.
+
+---
+
+## 7. Dialog Handling
+
+```python
+# Scenario: clicking a button triggers alert
+click_at_xy(200, 300)
+# Dialog appears, JS is frozen
+cdp("Page.handleJavaScriptDialog", accept=True)   # Click "OK"
+```
+
+Effect: When `alert()` / `confirm()` / `beforeunload` dialogs appear, dismiss them at the CDP level — invisible to the user, undetectable by anti-bot.
+
+To suppress all dialogs preemptively:
+```python
+js("""
+window.alert=m=>{};           # Silence alerts
+window.confirm=m=>true;       # Auto-confirm
+window.onbeforeunload=null;   # Disable leave confirmation
+""")
+```
+
+---
+
+## 8. Multi-tab Management
+
+```python
+# Scenario: switching between multiple pages
+tab1 = new_tab("https://a.com")            # Open first
+tab2 = new_tab("https://b.com")            # Open second
+switch_tab(tab1)                            # Switch back to first
+cdp("Target.activateTarget", targetId=tab1) # Bring to foreground (optional)
+
+# List all tabs
+for t in list_tabs():
+    print(t["url"][:60])
+```
+
+---
+
+## 9. Waiting for Page Load
+
+```python
+wait_for_load()                            # Wait for page to finish loading
+wait_for_text("Login")                     # Wait for text to appear (max 10s)
+```
+
+---
+
+## 10. Network Request Capture
+
+```python
+# Scenario: verify backend received form submission
+from browser_harness.helpers import NetworkMonitor
+monitor = NetworkMonitor()
+
+fill_form({"name": "Zhang San", "email": "a@b.com"})
+click_at_xy(500, 600)
+
+requests = monitor.get_requests()          # Get captured network requests
+```
+
+---
+
+## 11. Scrolling
+
+```python
+# Scenario: long page, scroll to bottom to load more
+js("window.scrollTo(0, document.body.scrollHeight)")
+wait_for_load()
+capture_screenshot()                       # Confirm new content appeared
+```
+
+---
+
+## 12. PDF Export
+
+```python
+# Scenario: save current page as PDF
+cdp("Page.printToPDF", landscape=False, printBackground=True)
+```
+
+---
+
+## 13. Keyboard Operations
+
+```python
+press_key("Enter")                         # Enter
+press_key("Tab")                           # Tab
+press_key("Escape")                        # Escape
+type_text("search keyword")                # Type text sequentially
+```
+
+---
+
+## 14. Debugging Tips
+
+```python
+# Stuck and don't know the state
+print(page_info())                         # Check title/URL/viewport
+print(current_tab())                       # Check which tab is attached
+tabs = list_tabs()                         # List all tabs
+ensure_real_tab()                          # Fix attachment to phantom tab
+```
+
+**Common Issues Quick Reference:**
+
+| Symptom | Cause | Solution |
+|---------|-------|----------|
+| Blank screenshot | Attached to omnibox phantom tab | `ensure_real_tab()` |
+| Click does nothing | Wrong coordinates / missed target | Re-screenshot, recalculate, or use `js` |
+| Page frozen | Dialog blocking JS | `cdp("Page.handleJavaScriptDialog", accept=True)` |
+| Link click no navigation | `beforeunload` blocking | `cdp("Page.handleJavaScriptDialog", accept=True)` |
+| Can't get data | Login required | Ask user to login, or `sync_local_profile` |
+| `js()` SyntaxError | PowerShell ate the double quotes | Use `--stdin` or bash script approach |
+| `page_info()` title has emoji | browser-harness auto-injection, normal | Ignore |
+| Sequential moves don't work | Wall/box blocking | `print(js('JSON.stringify(state)'))` check state |
+| `steps--` goes negative | Won't happen — `undo()` has `history.length` guard | But `undo` doesn't trigger win state reset |
+
+---
+
+## 15. Remote Cloud Browsers
+
+For **Browser Use Cloud** only — suitable for concurrent subtasks or maintenance-free operation.
+
+```python
+start_remote_daemon("work")                # Start a cloud browser
+start_remote_daemon("work", proxyCountryCode=None)  # Disable proxy
+```
+
+```bash
+BU_NAME=work browser-harness -c '
+new_tab("https://example.com")
+print(page_info())
+'
+```
+
+```python
+stop_remote_daemon("work")                 # Stop, billing stops
+```
+
+Start with login state:
+```python
+list_cloud_profiles()                      # List stored cloud profiles
+sync_local_profile("My Chrome Profile")    # Upload local cookies
+start_remote_daemon("work", profileName="My Chrome Profile")
+```
+
+---
+
+## 16. readwebfetch — Bypass Anti-Scraping
+
+**Scenario:** Site has anti-scraping (Cloudflare, JS challenge, bot detection), regular HTTP requests fail.  
+**How it works:** Extracts content via Readability.js in a real browser — no HTTP request, anti-bot can't detect it.
+
+**Prerequisite:** browser-harness auto-loads the `read_webfetch` extension when launching Chromium (`--load-extension`).
+
+```python
+d = readwebfetch("https://blog-link.com")
+print(d["title"])
+print(d["text"][:500])
+```
+
+**Return structure:**
+
+| Field | Description |
+|-------|-------------|
+| `url` | Page URL |
+| `title` | Page title |
+| `text` | Readability-extracted plain text |
+| `excerpt` | Summary |
+| `byline` | Author |
+
+**Execution:**
+
+```bash
+# bash script
+browser-harness -c '
+d = readwebfetch("https://blog.csdn.net/...")
+print(d["title"])
+print("Total " + str(len(d["text"])) + " chars")
+'
+```
+
+```powershell
+# PowerShell
+@'
+d = readwebfetch("https://blog.csdn.net/...")
+print(d["title"])
+print("Total " + str(len(d["text"])) + " chars")
+'@ | browser-harness --stdin
+```
+
+---
+
+## Windows PowerShell Notes
+
+- Use double quotes `"..."` for `-c` argument, single quotes `'...'` inside Python
+- Prefer `querySelector('#id')` over `getElementById("id")` to avoid quote nesting
+- Use `JSON.stringify(...)` for safe data transfer from js()
+- For complex scripts, write a `.py` file and pipe via `Get-Content`

+
+# Chrome DevTools MCP — Web Browsing & Debugging Skill
+
+Operation guide for the `chrome-devtools-mcp` toolset covering web browsing, interactive debugging, content extraction, and performance analysis.
+
+## When to Use
+
+Use this skill when **any** of the following apply:
+1. **Browsing** — need to navigate web pages, extract content, bypass login walls/paywalls
+2. **Debugging** — need to inspect console errors, network requests, DOM elements, or page performance
+3. **Content extraction** — need to extract article text from restricted pages (Zhihu, CSDN, etc.)
+4. **Interaction** — need to fill forms, click elements, handle dialogs on web pages
+5. **Performance** — need to run Lighthouse audits, trace performance, or capture heap snapshots
+
+## Core Workflow
+
+```
+1. new_page(url) / navigate_page(url)   → Open/navigate to page
+2. wait_for(["keyword"])                  → Wait for content to load
+3. take_snapshot()                        → Get element structure (uid)
+4. take_screenshot()                      → Confirm visual state
+5. evaluate_script(() => ...)            → Execute JS / extract data
+6. list_console_messages()                → Check console errors
+```
+
+## Key Capabilities
+
+- **Bypass restrictions**: Remove login/paywall overlays, unlock copy restrictions, expand truncated articles
+- **Debug JS errors**: List and inspect console messages, identify uncaught exceptions
+- **Network analysis**: List network requests, inspect request/response bodies
+- **DOM interaction**: Click, fill, type, hover, drag — all via accessibility tree (uid)
+- **Performance**: Lighthouse audits, performance traces, memory heap snapshots
+- **Device emulation**: Mobile viewport, user agent switching
+

+
+# Part 1 — Browsing & Restriction Bypass
+
+Based on `chrome-devtools-mcp` toolset for bypassing login walls, copy restrictions, and paywall overlays on sites like Zhihu, CSDN.
+
+## Standard Browsing Flow
+
+```
+Step 1: new_page(url)          → Open page
+Step 2: wait_for(["keyword"])  → Wait for content load
+Step 3: take_snapshot()        → Get accessibility tree (text structure)
+Step 4: take_screenshot()      → Confirm visual state (optional)
+Step 5: evaluate_script()      → Extract specific data
+```
+
+## Restriction Bypass Guide
+
+### 0. Standard Detect-Remove-Extract Pattern
+
+```javascript
+// Step 1: Detect
+evaluate_script(() => {
+  JSON.stringify({
+    hasMask: !!document.querySelector('[class*="mask"], [class*="overlay"], [class*="passport"]'),
+    hasReadMore: !!document.querySelector('.btn-readmore, [class*="readmore"], [class*="expand"]'),
+    articleLen: document.querySelector('article')?.innerText.length || 0,
+    title: document.title
+  })
+})
+
+// Step 2: Remove mask
+evaluate_script(() => {
+  document.querySelectorAll('[class*="mask"], [class*="overlay"], [class*="passport"], [class*="login"], [class*="modal"], .hide-article-box')
+    .forEach(el => el.remove());
+  document.body.style.overflow = 'auto';
+  document.body.style.position = '';
+  const a = document.querySelector('article');
+  if (a) { a.style.height = 'auto'; a.style.maxHeight = 'none'; }
+})
+
+// Step 3: Extract content
+evaluate_script(() => {
+  const a = document.querySelector('article') || document.querySelector('[class*="content"]') || document.querySelector('[class*="article"]');
+  return a?.innerText || 'not found';
+})
+```
+
+### 1. Bypass Login Wall / Paywall Overlay
+
+```javascript
+// Remove overlay elements
+evaluate_script(() => {
+  document.querySelectorAll('.login-guard, .pay-wall, .modal-mask, [class*="mask"], [class*="overlay"]')
+    .forEach(el => el.remove());
+})
+```
+
+```javascript
+// Remove body scroll lock and show content
+evaluate_script(() => {
+  document.body.style.overflow = 'auto';
+  document.querySelectorAll('.login-guard, .pay-wall, .sign-in, .modal, .overlay')
+    .forEach(el => el.remove());
+  // Restore hidden content
+  document.querySelectorAll('[class*="content"], [class*="article"], [class*="main"]')
+    .forEach(el => el.style.display = 'block');
+})
+```
+
+### 2. Unlock Copy Restrictions
+
+```javascript
+evaluate_script(() => {
+  document.addEventListener('copy', e => e.stopPropagation(), true);
+  document.addEventListener('selectstart', e => e.stopPropagation(), true);
+  document.body.style.userSelect = 'auto';
+  document.querySelectorAll('*').forEach(el => el.style.userSelect = 'auto');
+})
+```
+
+### 3. Extract Truncated Full Text
+
+```javascript
+// Standard flow: detect → remove mask → extract
+evaluate_script(() => {
+  const hasMask = !!document.querySelector('[class*="mask"], [class*="overlay"], [class*="passport"]');
+  const hasReadMore = !!document.querySelector('.btn-readmore, [class*="readmore"], [class*="expand"]');
+  return JSON.stringify({hasMask, hasReadMore, articleLen: document.querySelector('article')?.innerText.length || 0});
+})
+
+// If read-more button exists, click it first
+evaluate_script(() => {
+  const btn = [...document.querySelectorAll('button, a, span, div')]
+    .find(el => el.textContent.includes('展开阅读全文') || el.textContent.includes('全文'));
+  btn?.click();
+})
+```
+
+```javascript
+// Zhihu — expand full text
+evaluate_script(() => {
+  const btn = [...document.querySelectorAll('button, a, span')]
+    .find(el => el.textContent.includes('展开阅读全文') || el.textContent.includes('全文'));
+  if (btn) btn.click();
+})
+```
+
+```javascript
+// CSDN — remove login overlay + extract full text (verified 2026)
+evaluate_script(() => {
+  document.querySelectorAll('.mask, .mask-dark, .passport-login-tip-container, .passport-login-container, .passport-login-box, .passport-login-mark, .hide-article-box')
+    .forEach(el => el.remove());
+  document.body.style.overflow = 'auto';
+  document.body.style.position = '';
+  const article = document.querySelector('article') || document.querySelector('.article_content');
+  if (article) {
+    article.style.setProperty('height', 'auto', 'important');
+    article.style.setProperty('max-height', 'none', 'important');
+  }
+})
+
+// Extract content
+evaluate_script(() => {
+  const art = document.querySelector('article') || document.querySelector('.article_content') || document.querySelector('#article_content');
+  return 'Title: ' + document.title + '\n\n' + art.innerText;
+})
+```
+
+### 4. Extract Page Text
+
+```javascript
+// Get article plain text
+evaluate_script(() => {
+  const article = document.querySelector('article') ||
+    document.querySelector('[class*="content"]') ||
+    document.querySelector('[class*="article"]') ||
+    document.querySelector('main');
+  return article ? article.innerText : document.body.innerText;
+})
+```
+
+```javascript
+// Get all page text (preserving structure)
+evaluate_script(() => {
+  return [...document.querySelectorAll('h1, h2, h3, p, li, pre, code')]
+    .map(el => el.tagName + ': ' + el.innerText.trim())
+    .filter(s => s.length > 3)
+    .join('\n---\n');
+})
+```
+
+### 5. Zhihu-Specific Bypass
+
+```javascript
+evaluate_script(() => {
+  // Close dialog
+  document.querySelector('.Modal-closeButton, button[class*="close"]')?.click();
+  document.querySelector('[class*="signIn"], [class*="Modal"]')?.remove();
+  // Expand all collapsed answers
+  document.querySelectorAll('.RichContent.is-collapsed').forEach(el => {
+    el.classList.remove('is-collapsed');
+    el.style.height = 'auto';
+    el.style.maxHeight = 'none';
+    el.style.overflow = 'visible';
+  });
+  document.body.style.overflow = 'auto';
+})
+```
+
+### 6. WeChat Public Account Articles (Sogou Gateway)
+
+WeChat public account articles are normally login-gated in browsers, but Sogou WeChat Search (the official content index) allows direct access.
+
+```javascript
+// Step 1: Search for articles
+navigate_page('https://weixin.sogou.com/weixin?type=2&s_from=input&query=' + encodeURIComponent('search keyword'))
+
+// Step 2: Get result list
+evaluate_script(() => {
+  const items = [...document.querySelectorAll('.news-list2 .wx-rb, .news-list2 li')].filter(el => el.querySelector('h3 a'));
+  return items.slice(0, 10).map(el => ({
+    title: el.querySelector('h3 a')?.textContent?.trim(),
+    link: el.querySelector('h3 a')?.href,
+    source: el.querySelector('.account')?.textContent?.trim(),
+    date: el.querySelector('.time')?.textContent?.trim(),
+    summary: el.querySelector('.txt-info')?.textContent?.trim()?.slice(0, 80)
+  }));
+})
+
+// Step 3: Open article link (no login required)
+navigate_page('result-link')
+
+// Step 4: Extract content
+evaluate_script(() => document.body.innerText)
+```
+
+**Verified (2026):** Sogou WeChat Search for `chrome devtools` returns 634 results. Opening the link gives full 2856-character article with no restrictions.
+
+### 7. Mobile Emulation (some sites have fewer restrictions on mobile)
+
+```javascript
+emulate({
+  userAgent: 'Mozilla/5.0 (iPhone; CPU iPhone OS 16_0 like Mac OS X) AppleWebKit/605.1.15 (KHTML, like Gecko) Version/16.0 Mobile/15E148 Safari/604.1',
+  viewport: '375x667x2,mobile,touch'
+})
+```
+
+## Quick Command Reference
+
+| Operation | Tool | Description |
+|-----------|------|-------------|
+| Open page | `new_page(url)` | Open in new tab |
+| Navigate | `navigate_page(url)` | Navigate current tab |
+| Wait for content | `wait_for(["text"])` | Wait for text to appear |
+| Screenshot | `take_screenshot()` | Full-page screenshot |
+| DOM snapshot | `take_snapshot()` | Accessibility tree text structure |
+| Execute JS | `evaluate_script(fn)` | Arbitrary JS operations |
+| JS with args | `evaluate_script(fn, args)` | Execute with parameters |
+| Extract content | `evaluate_script(() => document.body.innerText)` | Plain text extraction |
+| Remove element | `evaluate_script(() => el.remove())` | Remove overlay/popup |
+| Click element | `click(uid)` | Click by snapshot uid |
+| Emulate device | `emulate({userAgent, viewport})` | Switch UA/viewport |
+| Scroll | `press_key({key: "Space"})` | Simulate key press |
+
+## FAQ (Practical Experience)
+
+### 1. Popup class names don't match?
+
+First inspect the actual overlay elements:
+```javascript
+evaluate_script(() => {
+  [...document.querySelectorAll('div[style*="fixed"], div[style*="absolute"], [class*="overlay"], [class*="modal"], [class*="mask"], [class*="popup"]')]
+    .map(el => ({tag: el.tagName, cls: el.className.slice(0,80), visible: el.offsetParent !== null}))
+})
+```
+
+### 2. How to tell if content is complete or truncated?
+
+```javascript
+evaluate_script(() => {
+  const a = document.querySelector('article') || document.querySelector('.Post-RichText');
+  const ratio = a.scrollHeight / a.clientHeight;
+  JSON.stringify({
+    textLen: a.innerText.length,
+    scrollH: a.scrollHeight, clientH: a.clientHeight,
+    ratio: ratio.toFixed(2), // > 1.2 means overflow hidden
+    endText: a.innerText.slice(-100)
+  })
+})
+```
+
+If it ends with `-- The End --`, copyright notice, or a natural ending, it's complete.
+
+### 3. CSDN overlay class names (verified 2026)
+
+| CSDN Class | Description |
+|------------|-------------|
+| `.mask` + `.mask-dark` | Background overlay |
+| `.passport-login-tip-container` | Login prompt bar |
+| `.passport-login-container` | Login dialog container |
+| `.passport-login-box` / `.passport-login-mark` | Login box and overlay |
+| `.hide-article-box` | Article collapse bar |
+
+### 4. Zhihu overlay class names (verified 2026)
+
+| Zhihu Class | Description |
+|-------------|-------------|
+| `.Modal.Modal--default.signFlowModal` | Login dialog |
+| `.signFlowModal-container` | Login container |
+| Content selector: `.Post-RichText` or `.RichText` | |
+
+### 5. Short article vs truncated article
+
+- Some articles are genuinely short (many images/code, few words) — e.g., 2081 chars but scrollHeight = 8550px
+- Verification: check end for natural termination, or confirm via `document.title`
+- Zhihu columns without login may redirect to search page — check `location.href`
+
+### 6. What can vs cannot be bypassed
+
+| Type | Principle | Bypassable? | Example |
+|------|-----------|-------------|---------|
+| DOM overlay | Content in DOM, hidden behind a div | Yes — just remove it | CSDN, Zhihu columns |
+| Lazy load | Content loaded on scroll | Yes — trigger scroll | Most comment sections |
+| API auth | Content fetched via cookie-authenticated API | No — no cookie = no data | Bilibili comments, Weibo |
+| SSR hidden | Server-rendered but hidden via class | Yes — change style | Juejin paid articles |
+
+### 7. Chrome restart / disconnect handling
+
+MCP mode manages browser lifecycle automatically. CLI mode:
+```bash
+chrome-devtools stop     # Stop background process
+chrome-devtools status   # Check status
+```

+name: deep-systems-debugger
+description: Use when debugging multi-layer or distributed systems where the root cause may reside in a different architectural layer than the symptom, or when standard debugging has not identified the root cause after initial investigation
+---
+
+# Deep Systems Debugger
+
+## Overview
+
+In multi-layer systems (CI/CD, distributed services, complex pipelines), the root cause almost never lives in the same layer as the symptom. Random patching wastes time. This skill provides a structured four-phase protocol for tracing failures across architectural boundaries with surgical precision.
+
+**Core principle:** Map every layer and trace every boundary before forming any hypothesis. Be the detective, not the gambler.
+
+## The Iron Law
+
+```
+NO FIXES WITHOUT COMPLETED ROOT-CAUSE INVESTIGATION
+```
+
+If you have not finished Phase 1, you are forbidden from proposing code changes, configuration tweaks, or operational patches.
+
+## When to Use
+
+- Error manifests in a different layer than where the cause likely lives
+- System has 3+ architectural layers (CI/CD pipeline, API gateway → service → DB, distributed services)
+- Error message is a transport-level symptom (HTTP error, timeout, decode failure, connection refused)
+- Standard investigation has been attempted but root cause remains unclear
+- Intermittent or environment-specific failures
+- The failure involves configuration, build, or deployment scripts
+- Multiple failed fix attempts have already been made
+
+**Do NOT use for:** Simple single-layer bugs (use `systematic-debugging` instead)
+
+## Prerequisites
+
+This skill builds on `systematic-debugging`. If you haven't completed Phase 1-2 of that skill, start there first.
+
+## Quick Reference
+
+| Phase | Focus | Key Technique | Output |
+|-------|-------|--------------|--------|
+| **1. Root-Cause Mapping** | Observe only | Recursive diff, error routing, boundary instrumentation | Evidence log, divergence point |
+| **2. Pattern Analysis** | Analyze before theorizing | Backward tracing, working reference comparison | Single clear hypothesis |
+| **3. Scientific Validation** | Minimal experiment | One variable change | Confirmed or rejected hypothesis |
+| **4. Permanent Fix** | Lock in root cause | Failing test, isolated fix, regression suite | Fixed bug + test |
+
+## Phase 1: Root-Cause Mapping & Evidence Gathering
+
+*Do not propose fixes. Only observe and trace.*
+
+### 0. Perform Full Recursive Diff of All Layers
+
+Before reading any code, diff the **entire** broken codebase against a known-good reference (previous version, sibling branch, stable release). Sort diff output by architectural layer, outermost to innermost:
+
+```
+[CI/Dockerfile] → [Build scripts] → [HTTP client config] → [API wiring] → [Middleware/policy] → [Feature dispatch] → [Business logic]
+```
+
+Examine **every** difference, especially in configuration files, builder chains, dependency versions, environment variable handling, and client setup code. Do not filter by suspected feature area.
+
+### 1. Route by Error Type, Then Map from Outermost Layer
+
+Let the **error message text** determine the starting layer:
+
+| Error Keyword | Starting Layer |
+|--------------|----------------|
+| `http error`, `decode`, `timeout`, `connection refused` | HTTP client config / transport layer |
+| `permission denied`, `auth`, `policy` | Middleware / enforcer / policy layer |
+| `parse`, `serialize`, `invalid format` | Serialization / API boundary |
+| `null pointer`, `index out of bounds`, `unreachable` | Business logic layer |
+
+Trace outward from that layer: identify every architectural layer from outermost trigger down to deepest call. List all middleware, adapters, policy enforcers, aliases, and caching layers.
+
+### 2. Identify All Data Boundaries
+
+For each function, module, or service in the chain, explicitly define:
+
+- **Input**: What enters (type, format, size, origin)
+- **Output**: What exits (type, format, serialization, destination)
+- **Side Effects**: State mutations, cache writes, external I/O, logging, metric emissions
+
+### 3. Instrument with Diagnostic Tracing
+
+At **EVERY** critical boundary, insert tracing logic (structured logs, print statements, metric counters, span attributes). Record:
+
+- Entry/exit timestamps
+- Key input metadata (ID, length, checksum, source)
+- Key output metadata (status code, size, target location)
+- Environment/context values (auth tokens, feature flags, config overrides)
+
+**Post-trace sanity check:** Before analyzing, scan which layers produced output vs. produced no output. If the outermost transport layer shows the first error, do NOT dig deeper — the failure is already localized.
+
+For large payloads, log size, hash, or truncated preview — never flood logs with raw data.
+
+### 4. Gather Empirical Evidence
+
+Execute the reproduction path once with instrumentation active. Compare observed outputs against expected outputs at every boundary. Note where the two first diverge — that is your initial suspect region.
+
+## Phase 2: Pattern Analysis & Hypothesis Formation
+
+*Analyze evidence before forming a theory.*
+
+1. **Locate Divergence Point** — Find the **first** boundary where reality differs from expectation.
+2. **Perform Backward Tracing** — If error manifests deep in stack, ask repeatedly: *"What component supplied this incorrect value?"* Follow chain upward to the original source of invalid state.
+3. **Compare Against Working References** — Identify a similar known-good path. List **every** difference, no matter how trivial.
+4. **Formulate a Single Clear Hypothesis** — Write explicitly: *"The root cause is likely [X], because the trace shows [Y] at [Z], and this differs from the working example where [W] happens."*
+
+## Phase 3: Scientific Validation (Minimal Experimentation)
+
+*Test the hypothesis with surgical restraint.*
+
+1. **Design the smallest possible test** — Make **one** isolated change to validate your hypothesis. Change only one variable at a time.
+2. **Run the reproduction** — If the change resolves the issue → proceed to Phase 4. If not → **STOP**. Discard that hypothesis. Return to Phase 2 with fresh evidence.
+3. **NEVER** apply multiple fixes in one test run — you lose the ability to isolate causality.
+
+## Phase 4: Permanent Implementation & Verification
+
+*Fix the root cause and lock it in.*
+
+1. **Create a failing test case** — Minimal automated test that reliably reproduces the original failure.
+2. **Apply the single, root-cause fix** — Modify only what is necessary. No opportunistic refactoring.
+3. **Run full verification** — New test passes. Existing regression suite passes. Original symptom is gone.
+4. **If the fix fails after 3 attempts** — **STOP**. Escalate to architectural review. Repeated failures suggest a deeper structural flaw (improper layering, incorrect state ownership, broken abstraction).
+
+## Command Patterns (Action Sequence)
+
+When beginning a deep debugging session, follow this sequence:
+
+1. **`DIFFING`** — Recursive diff broken vs working across ALL files, sorted outermost to innermost
+2. **`MAPPING`** — Route by error type, search codebase, construct end-to-end call chain table
+3. **`INSTRUMENTING`** — Generate tracing/logging at every identified boundary
+4. **`ANALYZING`** — Execute reproduction, capture traces, pinpoint first divergence
+5. **`HYPOTHESIZING`** — State single clear hypothesis with supporting evidence
+6. **`VALIDATING`** — Implement minimal change to test hypothesis; report result
+7. **`FIXING`** — Commit permanent isolated fix and accompanying regression test
+
+## Universal Constraints
+
+- **Separate data flow from presentation flow** — UI layers consume final output; they are rarely the source of logical corruption. Focus on the core transactional data pipeline.
+- **Track all hidden state** — Explicitly log cache hits/misses, environment variables, config precedence, feature flags, and global singletons.
+- **Reproducibility first** — If intermittent, increase observability across multiple runs. Do not guess at race conditions.
+- **Environment parity** — Always verify if the bug exists only in specific environments. Compare configs, resource limits, and dependency versions.
+
+## Red Flags (Immediate Halt)
+
+If you catch yourself thinking any of these, STOP and return to Phase 1:
+
+- "Let's just change this one thing and see if the test passes."
+- "It's probably a race condition; let's add a sleep."
+- "I'll write the test after I confirm it works manually."
+- "I'll fix these two related issues together since I'm here."
+- "This is trivial; I don't need to trace the whole flow."
+- "I've tried two patches already — maybe a third will stick."
+
+## Output Structure
+
+When reporting findings, use this format:
+
+### 1. Execution Chain Overview
+`[Layer A] → [Layer B] → [Layer C] → ... → [Layer N]`
+
+### 2. Boundary Trace Table
+| Boundary | Input | Expected Output | Actual Output | Status |
+|----------|-------|----------------|---------------|--------|
+| ... | ... | ... | ... | ✅/❌ |
+
+### 3. Root-Cause Hypothesis
+*[Concise statement of the suspected origin, supported by trace evidence.]*
+
+### 4. Validation Experiment
+*[Description of the minimal change made and the observed result.]*
+
+### 5. Final Resolution
+*[The committed fix, the regression test added, and confirmation of success.]*

+# Performance Tuning Guidelines
+
+## When to Use
+
+When opencode performance needs optimization for:
+- Faster response times and lower latency
+- Reduced memory usage and better resource management
+- Improved large project handling
+- Better concurrent operation support
+- Optimal configuration for your hardware and workflow
+
+## How It Works
+
+opencode's performance can be tuned across multiple dimensions: memory usage, CPU efficiency, disk I/O, network latency, and configuration optimization. This skill provides comprehensive guidelines for each area.
+

+
+```bash
+#!/bin/bash
+# ~/.opencode/benchmark.sh
+
+echo "Running opencode performance benchmarks..."
+echo "=========================================="
+
+# Startup time
+echo -n "Startup time: "
+time opencode --version > /dev/null

+opencode profile-memory --quick | grep "heapUsed"
+
+# File loading
+echo -n "File loading (100KB): "
+time opencode eval "fs.readFileSync('test-100kb.txt', 'utf8')" > /dev/null
+
+# Syntax highlighting

+
+# Code analysis
+echo -n "Code analysis: "
+time opencode eval "analyze('test.js')" > /dev/null
+
+echo "Benchmark complete."
+```
+
+### 2. Regression Testing
+
+```json
+{
+  "regressionTesting": {
+    "enabled": true,
+    "tests": [
+      {
+        "name": "startupTime",

+      }
+    ],
+    "schedule": "daily",
+    "alertOnRegression": true
+  }
+}
+```
+
+## Troubleshooting Performance Issues
+
+### 1. Diagnostic Commands
+
+```bash
+# Check current performance stats
+opencode perf-stats
+
+# Generate performance report
+opencode perf-report --output report.html
+
+# Identify bottlenecks
+opencode perf-bottlenecks
+
+# Compare configurations
+opencode perf-compare config1.json config2.json
+
+# Reset to defaults
+opencode perf-reset
+```
+
+### 2. Common Issues and Solutions
+
+**High Memory Usage:**
+- Reduce cache sizes
+- Enable garbage collection tuning
+- Limit concurrent operations
+- Disable memory-intensive features
+
+**Slow Startup:**
+- Enable lazy loading
+- Reduce preloaded modules
+- Disable unnecessary plugins
+- Use faster storage (SSD)
+
+**High CPU Usage:**
+- Reduce worker threads
+- Disable background indexing
+- Limit syntax highlighting complexity
+- Use simpler algorithms
+
+**Network Latency:**
+- Enable compression
+- Use connection pooling
+- Implement caching
+- Reduce request size
+
+## Best Practices
+
+### 1. Regular Maintenance
+
+- Monitor performance metrics regularly
+- Clean up cache files periodically
+- Update to latest versions
+- Review and optimize configuration
+- Remove unused plugins and extensions
+
+### 2. Progressive Optimization
+
+1. **Baseline**: Establish current performance metrics
+2. **Identify**: Use profiling to find bottlenecks
+3. **Prioritize**: Focus on highest-impact optimizations
+4. **Implement**: Apply optimizations incrementally
+5. **Verify**: Test after each change
+6. **Monitor**: Continuously track performance
+
+### 3. Configuration Management
+
+- Keep configurations in version control
+- Document optimization decisions
+- Create environment-specific configurations
+- Use inheritance for common settings
+- Validate configurations regularly

+# Claw Code Installation Guide
+
+> One-click installation instructions for Windows users. The entire process is: download, extract, and double-click a single `.bat` file.
+
+## 1. Download
+
+Get the two files from [GitHub Releases](https://github.com/huagusam/clawcode/releases/latest):
+
+| File | Download URL | Description |
+|---|---|---|
+| `Config_methods.7z` | [Download here](https://github.com/huagusam/clawcode/releases/download/v0.2.2.2/Config_methods.7z) | **Full installer package** — includes `claw.exe`, Git, fd, rg, config files, and the installation script |
+| `claw.exe` | [Download here](https://github.com/huagusam/clawcode/releases/download/v0.2.2.1/claw.exe) | Standalone main binary (optional; already bundled in the installer package) |
+
+> We recommend simply downloading **`Config_methods.7z`** — a single file completes the full installation.
+
+## 2. Extract
+
+1. Right-click `Config_methods.7z` → **Extract All** (built into Windows; install [7-Zip](https://www.7-zip.org/) if not available)
+2. After extraction you get the `Install_Config_methods` folder containing:
+   - `claw.exe` — main binary
+   - `Git.7z` — offline Git Bash installer
+   - `fd.exe` / `rg.exe` — search tools
+   - `.claw/` — configuration directory
+   - `install_claw.bat` — **one-click installation script**
+
+> Note: the folder path must **not contain non-ASCII characters**, e.g. put it at `D:\claw\Install_Config_methods`.
+
+## 3. One-Click Install
+
+1. Enter the extracted `Install_Config_methods` folder
+2. **Double-click `install_claw.bat`** and accept the administrator prompt (click "Yes" on the UAC dialog)
+3. The script will automatically complete:
+
+| Step | Action |
+|---|---|
+| 1/5 | Detect Git Bash: skip if installed, otherwise extract `Git.7z` to `C:\Program Files\Git` |
+| 2/5 | Copy `fd.exe` and `rg.exe` to `C:\Program Files\Git\bin` |
+| 3/5 | Copy `claw.exe` to `C:\Users\<your-username>\.local\bin` and create a `claw` shortcut on the desktop |
+| 4/5 | Copy the `.claw` config folder to `C:\Users\<your-username>\.claw` (overwrites old config) |
+| 5/5 | Add `C:\Program Files\Git\bin` and `.local\bin` to the system PATH |
+
+You will see **"Installation finished"** once the installation succeeds.
+
+## 4. Getting Started
+
+1. **Reopen** a new terminal window (cmd / PowerShell / Windows Terminal) so the PATH takes effect
+2. Double-click the **`claw`** shortcut on the desktop, or type `claw` and press Enter in a terminal
+3. On first use, configure the API: edit `C:\Users\<your-username>\.claw\.env` and fill in your API Key and model:
+
+```env
+ANTHROPIC_BASE_URL=https://api.anthropic.com
+ANTHROPIC_API_KEY=sk-ant-xxxxxxxx
+ANTHROPIC_MODEL=claude-sonnet-4-20250514
+```
+
+> For local models (LM Studio / llama.cpp / Ollama): `ANTHROPIC_BASE_URL` only needs the server address (**do not** add `/v1` — claw automatically appends `/v1/messages`). The port varies by service: LM Studio `1234`, llama-server `8080`, Ollama `11434`.
+
+## 5. FAQ
+
+| Problem | Solution |
+|---|---|
+| The window flashes and closes after double-clicking the bat | Right-click `install_claw.bat` → Run as administrator |
+| "7-Zip not found" error | Install [7-Zip](https://www.7-zip.org/) and rerun the script |
+| `claw` command not found | Confirm the PATH has taken effect, or reopen the terminal and try again |
+| No desktop shortcut | Check the installation log, or manually create a shortcut pointing to `C:\Users\<your-username>\.local\bin\claw.exe` |
+| How to uninstall | Delete `C:\Users\<your-username>\.local\bin\claw.exe`, `C:\Users\<your-username>\.claw`, and the desktop shortcut |
+
+## 6. Building from Source (Optional)
+
+Requires a Rust + MSVC + Clang-CL environment; see the project [README](README.md).

+/// ## Typical workflow (per agentic-loop iteration)
+/// 1. Build a fresh `MessageRequest` (or reuse the previous one with a new
+///    message appended).
+/// 2. Call `update(&request)` — only new/uncached messages are serialized.

+/// ## Base invalidation
+/// The "base" portion (`model`, `max_tokens`, `system`, `tools`, `tool_choice`,
+/// `stream`, tuning knobs) is cached until a field actually changes.  Changes
+/// are detected via a simplified content hash of the non-message fields.
+///
+/// ## Zero-alloc build\_bytes

+//! Reasoning-effort registry: per-provider supported levels, wire-translation
+//! helpers, and fail-fast validation.
+//!
+//! This mirrors the dsh reasoning-effort model: a typed [`ReasoningEffort`]
+//! enum resolves to a provider-specific wire spelling — or field omission for
+//! [`ReasoningEffort::Off`] — before any network I/O. The registry is the
+//! single source of truth for which levels a (provider, model) pair exposes
+//! and what each level emits on the wire; the provider emit code calls these
+//! helpers instead of open-coding the translation.
+//!
+//! Design notes:
+//! - Levels and defaults are structural facts about providers, not deployment
+//!   choices, so they live in compiled code (like `MODEL_REGISTRY` and
+//!   `is_reasoning_model`). Deployment-varying values — the *selected* level —
+//!   flow in through env / settings.json / CLI / agent frontmatter.
+//! - `Off` always means "omit the wire field" (`None`), never send the string
+//!   `"off"`: OpenAI-compat has no `off` spelling and would reject it.
+//! - A non-reasoning model exposes only `Off`; any other level is rejected at
+//!   validation time so a stale `--reasoning-effort high` against a
+//!   non-reasoning model fails before the request leaves the process.

+//! Minimal, self-contained MCP server used by the `claw-cli` test suite
+//! to exercise end-to-end MCP tool/resource discovery and execution.
+//!
+//! It speaks the LSP-style JSON-RPC-over-stdio framing (HTTP `Content-Length`
+//! headers) so the production MCP client can drive it without any external
+//! interpreter (no python3/node) being installed. This keeps the suite portable.
+//!
+//! Run with no args for the working `echo` server. Pass `--broken` to simulate a
+//! server that fails to start (the process exits immediately, so tool discovery
+//! for that server fails at the `tool_discovery` phase).

+//! Strip environment variables that could subvert sandbox enforcement or
+//! let a child process escape isolation. Modeled on tidev's
+//! `process_hardening::remove_dangerous_env_vars_parent` (process_hardening.rs:97)
+//! and extended for Windows-specific attack surfaces:
+//!
+//! | Variable | Platform | Attack |
+//! |---|---|---|
+//! | `LD_PRELOAD` | any with libc | Shared-library injection — child loads attacker .so |
+//! | `LD_LIBRARY_PATH` | any with libc | Library search-path override |
+//! | `LD_AUDIT` | any with libc | Audit library injection |
+//! | `DYLD_INSERT_LIBRARIES` | macOS | Same as LD_PRELOAD for Mach-O |
+//! | `DYLD_LIBRARY_PATH` | macOS | Same as LD_LIBRARY_PATH for Mach-O |
+//! | `PSModulePath` | Windows | PowerShell module hijack — child can shadow real modules |
+//! | `NODE_OPTIONS` | Windows/macOS | Node.js `--require` injection — preload arbitrary JS |
+//! | `MSYS2_ARG_CONV_EXCL` | Windows (MSYS2) | Path-conversion reversal — quoted args become unquoted |
+//! | `MSYS2_ENV_CONV_EXCL` | Windows (MSYS2) | Same family — env-var value conversion attack |
+//!
+//! This MUST be called in the **parent** process before `spawn()`, never
+//! inside a `pre_exec` closure. Allocating or touching the environment
+//! after `fork()` (or its Win32 equivalent) can deadlock if another
+//! thread is holding the heap lock.
+//!
+//! Mutating the parent's environment is permanent for the rest of the
+//! agent loop. That's intentional: the agent should never honor these
+//! vars anywhere — not in subsequent tool calls, not in hook scripts.

+//! Windows Job Object FFI.
+//!
+//! The runtime crate compiles with `forbid(unsafe_code)` at the workspace
+//! level, so all Win32 calls (`OpenProcess`, `CloseHandle`, `TerminateProcess`)
+//! are confined to this submodule. The inner attribute here re-enables
+//! `unsafe` only for the FFI surface; every caller in `bash.rs` stays safe.
+//!
+//! Contract:
+//! - `apply_job_object_to_pid(pid, enabled, label)` — if `enabled`, create
+//!   a Job Object with `kill_on_job_close`, assign the process, and leak
+//!   the Job handle so the kernel keeps it alive until the parent exits.
+//!   Returns `Err` when the Job cannot be applied (e.g. nested-Job
+//!   `E_ACCESSDENIED`) so the caller can decide whether to proceed.
+//! - `kill_pid(pid)` — terminate the process by pid. Best-effort: errors
+//!   are swallowed because the async caller has already given up.

+//! `render_reasoning` — formats accumulated reasoning text as an
+//! ANSI-styled terminal block with a `┃` gutter and a
+//! `Thinking:` / `Thought:` label.
+//!
+//! The renderer applies a *mixed* dimmed color (foreground blended
+//! toward the background by a fixed ratio) rather than the `\x1b[2m`
+//! DIM attribute. The DIM attribute renders inconsistently across
+//! terminals (Windows Terminal dims heavily; Ghostty barely dims at
+//! all). Using a literal mixed color gives the same visual on every
+//! terminal.
+//!
+//! The renderer does **not** perform markdown processing — it treats
+//! the input as opaque text and applies word-wrap at `width - 2` (to
+//! account for the `┃ ` gutter). Callers that want markdown rendering
+//! of the reasoning should pre-render with their markdown helper of
+//! choice and pass the lines through [`render_reasoning_lines`].
+

-/// Candidate `unshare` user-namespace mapping options, in preference order.
-///
-/// Most systems accept `--map-root-user` alone. Some hardened containers and
-/// seccomp profiles block unprivileged writes to `/proc/self/uid_map`; there,
-/// util-linux delegates to the setuid `newuidmap`/`newgidmap` helpers when
-/// `--map-auto` is also present.
-///
-/// That fallback therefore depends on the setuid helpers (the `uidmap`
-/// package on Debian/Ubuntu) and on the current user having a range in
-/// `/etc/subuid` and `/etc/subgid`. When either is missing, `--map-auto`
-/// fails and the startup probe rejects the candidate, keeping the plain form.
-///
-/// Each candidate is the **complete** static argument shape the launcher
-/// uses (see `build_linux_sandbox_command`): mapping flags followed by the
-/// namespace flags `--mount --ipc --pid --uts --fork`. The startup probe
-/// runs each candidate verbatim (plus a trivial program), so probe success
-/// implies launch success: on systems where the mapping works but the
-/// namespace flags are denied (e.g. AppArmor-restricted CI runners that
-/// block mount propagation in user namespaces), the probe fails and the
-/// sandbox stays disabled instead of activating a launcher that always
-/// errors.
-///
-/// `--net` is intentionally absent: it is appended only when network
-/// isolation is active (the non-default path), and probing with it would
-/// disable the sandbox on hosts that block network-namespace creation (e.g.
-/// Docker's default seccomp profile) even when network isolation is never
-/// requested.

-The in-code fixture in `runtime::report_schema::tests::fixture_report` covers:
-- fact / hypothesis / confidence labels
-- negative evidence with checked surfaces and query window
-- field-level delta attribution
-- canonical report id plus content hash
-- deterministic projection/redaction provenance
-- consumer capability negotiation and downgraded projections

-# Git-Aware Context Tools
-
-Adds five native git tools to claw-code that provide structured, read-only access to repository state. These replace ad-hoc `git` commands via bash with purpose-built tool definitions the model can discover and invoke directly.
-
-## Tools
-
-### GitStatus
-
-Show the working tree status (branch, staged, unstaged, untracked). Equivalent to `git status --short --branch`.
-
-| Parameter | Type | Required | Default | Description |
-|-----------|------|----------|---------|-------------|
-| `short` | boolean | no | `true` | Use `--short --branch` format for concise output |
-
-**Example input:**
-```json
-{}
-```
-
-**Example output:**
-```json
-{
-  "output": "## feat/git-aware-tools...upstream/main [ahead 1]\nM rust/crates/tools/src/lib.rs"
-}
-```
-
----
-
-### GitDiff
-
-Show changes between commits, the index, and the working tree. Supports staged changes, specific paths, commit ranges, and comparing two commits.
-
-| Parameter | Type | Required | Default | Description |
-|-----------|------|----------|---------|-------------|
-| `staged` | boolean | no | `false` | Show staged changes (`git diff --cached`) |
-| `commit` | string | no | — | Commit hash, tag, or branch to diff against |
-| `commit2` | string | no | — | Second commit for range diff (`commit...commit2`) |
-| `path` | string | no | — | File path to restrict the diff to |
-
-**Example inputs:**
-```json
-{}
-```
-```json
-{ "staged": true }
-```
-```json
-{ "commit": "HEAD~3", "path": "rust/crates/tools/src/lib.rs" }
-```
-```json
-{ "commit": "main", "commit2": "feat/git-aware-tools" }
-```
-
----
-
-### GitLog
-
-Show commit history. Supports limiting count, filtering by author/date/path, and oneline format.
-
-| Parameter | Type | Required | Default | Description |
-|-----------|------|----------|---------|-------------|
-| `count` | integer | no | `20` | Maximum number of commits to return |
-| `oneline` | boolean | no | `false` | Use `--oneline` format (hash + subject only) |
-| `author` | string | no | — | Filter commits by author pattern |
-| `since` | string | no | — | Filter commits since date (e.g. `"2024-01-01"` or `"2.weeks"`) |
-| `until` | string | no | — | Filter commits until date |
-| `path` | string | no | — | File or directory path to filter commits by |
-
-**Example inputs:**
-```json
-{ "count": 5, "oneline": true }
-```
-```json
-{ "author": "alice", "since": "1.week", "path": "src/main.rs" }
-```
-
----
-
-### GitShow
-
-Show a commit, tag, or tree object with its diff. Supports showing a specific file at a commit and stat-only mode.
-
-| Parameter | Type | Required | Default | Description |
-|-----------|------|----------|---------|-------------|
-| `commit` | string | **yes** | — | Commit hash, tag, or branch ref to show |
-| `path` | string | no | — | Show only this file at the given commit (`commit:path` syntax) |
-| `stat` | boolean | no | `false` | Show diffstat summary instead of full diff |
-
-**Example inputs:**
-```json
-{ "commit": "HEAD" }
-```
-```json
-{ "commit": "abc1234", "stat": true }
-```
-```json
-{ "commit": "main", "path": "src/lib.rs" }
-```
-
----
-
-### GitBlame
-
-Show what revision and author last modified each line of a file. Supports line range filtering.
-
-| Parameter | Type | Required | Default | Description |
-|-----------|------|----------|---------|-------------|
-| `path` | string | **yes** | — | File path to blame |
-| `start_line` | integer | no | — | Start of line range (1-based) |
-| `end_line` | integer | no | — | End of line range (1-based) |
-
-**Example inputs:**
-```json
-{ "path": "src/main.rs" }
-```
-```json
-{ "path": "src/main.rs", "start_line": 100, "end_line": 150 }
-```
-
----
-
-## Architecture
-
-All five tools follow the same pattern:
-
-1. **ToolSpec** — Defines the tool name, description, JSON input schema, and `PermissionMode::ReadOnly`
-2. **Input struct** — Derives `Deserialize` with `#[serde(default)]` on optional fields
-3. **Run function** — Builds git arguments, calls `git_stdout()`, wraps result in JSON via `to_pretty_json()`
-4. **Dispatch** — Matched in `execute_tool_with_enforcer()` like all other tools
-
-The existing `git_stdout(args: &[&str]) -> Option<String>` helper (at `tools/src/lib.rs`) handles running the `git` subprocess and returning trimmed stdout. Git tools simply construct the right arguments and delegate to this helper.
-
-## Why native git tools?
-
-Before this PR, the model had to use the `bash` tool for git operations, which has several drawbacks:
-
-- **No structured output** — Bash returns raw text that the model must parse
-- **Over-permissioned** — Bash requires `DangerFullAccess` even for read-only git commands
-- **No discoverability** — The model can't search for git-capable tools via `ToolSearch`
-- **Inconsistent** — Each invocation may use different flags or formatting
-
-With native git tools:
-
-- All five are `ReadOnly` — safe in restricted permission modes
-- Structured JSON output — consistent, parseable results
-- Discoverable via `ToolSearch` with keywords like "git", "diff", "blame"
-- Model-friendly descriptions explain when to use each tool vs bash
-
-## Testing
-
-```bash
-cd rust
-cargo build --release
-cargo test -p tools
-```
-
-The 3 pre-existing test failures (agent_fake_runner, agent_persists_handoff, worker_create_merges_config) are unrelated to this change — they fail due to local settings.json incompatibilities.
