## What's Different

| Feature | Qwen Code | proto |
| ---------------- | ----------------------- | ------------------------------------------------------------------------------ |
| Default model | Qwen3-Coder | Any (configurable) |
| Task management | In-memory JSON | [beads_rust](https://github.com/Dicklesworthstone/beads_rust) (SQLite + JSONL) |
| Memory | Single append-only file | File-per-memory with YAML frontmatter, 4-type taxonomy, auto-extraction |
| MCP servers | None | Configurable via `~/.proto/settings.json` |
| Plugin discovery | Qwen only | Auto-discovers Claude Code plugins from `~/.claude/plugins/` |
| Skills | Nested superpowers | Flat bundled skills (16 skills, all discoverable) |
At-a-glance overview vs. upstream Qwen Code. For the full architectural breakdown see [`docs/architecture/divergence-from-upstream.md`](./docs/architecture/divergence-from-upstream.md).

| Category | Qwen Code | proto |
| --------------------- | ------------------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------- |
| Default model | Qwen3-Coder | Any (LiteLLM / OpenAI-compat / Anthropic / Gemini) |
| Agent harness | — | Sprint contracts + scope lock, behavior-verify gate, multi-sample selector, doom-loop reminders, session memory + evolve, checkpoint/rewind, speculation |
| Bundled skills | 0 (use external) | 22 (sprint-contract, verification-before-completion, systematic-debugging, …) |
| Subagent execution | Sequential | Concurrent batched — Agent calls run in parallel; tool ordering preserved |
| Tool-call streaming | Per-converter parser | Per-stream parser context (no cross-stream corruption); malformed JSON → UI-hidden recovery note |
| Reasoning models | Basic `reasoning_content` | Inline `<think>`-tag extraction (Minimax/QwQ); reasoning-only `content: ""` fix; preserved on session resume |
| Truncation handling | Best-effort | MAX_TOKENS cascade detection + tool-response trimming; rejected truncated edits |
| Task management | In-memory JSON | [beads_rust](https://github.com/Dicklesworthstone/beads_rust) (SQLite + JSONL) |
| Memory | Single append-only file | File-per-memory with YAML frontmatter, 4-type taxonomy, auto-extraction |
| MCP servers | None | Configurable via `~/.proto/settings.json`; SSE/HTTP/stdio in ACP mode |
| Plugin discovery | Qwen only | Auto-discovers Claude Code plugins from `~/.claude/plugins/` |
| Ignore files | `.qwenignore` | `.protoignore` + inherits `.claudeignore` patterns |
| ACP / Zed integration | Stock | Cron-in-Session, concurrent Agent calls, SSE/HTTP MCP, internal-part filtering |
| Extra built-in tools | Standard set | + browser automation, repo-map (PageRank), task tools, mailbox, LSP, voice/STT |
| Observability | Console | Langfuse OTLP traces with harness-intervention spans (SFT-ready) |
| Release pipeline | Manual | Conventional-commit auto-release (`feat:` → minor, `fix:` → patch) |
| VS Code companion | Included | Removed (focus on TUI + ACP/Zed) |
