feat(cli): add /chat file commands for session management

[lnxsun]

Summary

Add project-level custom slash commands for saving, listing, resuming, and deleting named chat sessions.

Command	Description
/chat -s <name>	Save current session with a human-readable name
/chat -l	List all saved sessions
/chat -r <name>	Resume a saved session in a new terminal window
/chat -d <name>	Delete a session name from index (session file preserved)

Background

Related to #3025.

An earlier implementation as core source code was submitted in #3105 but was closed due to inconsistency with
Qwen Code's roadmap (PR #1113 deprecated built-in /chat commands in favor of --continue/--resume CLI
arguments).

This PR re-imagines the feature as file-based custom commands under .qwen/commands/, requiring zero core
code changes. Anyone can drop these files into their project and get named session management immediately.

Security

• Prototype pollution prevention: Blocks __proto__, constructor, prototype as session names
• Input validation: Regex ^[a-zA-Z0-9_.-]+$, max 128 chars, reserved name blocking
• Confirmation prompts: Overwrite and delete require explicit yes/no confirmation
• Shared reference protection: Deleting a session name does not destroy the underlying session file
  (multiple names can reference the same UUID)

Cross-platform Support

OS	Resume Command
Windows (PowerShell)	start pwsh -NoExit -Command "qwen --resume <id>"
macOS	osascript -e 'tell app "Terminal" to do script "qwen --resume <id>"'
Linux (GNOME)	gnome-terminal -- qwen --resume <id>

Token Efficiency

• Production files: ~2,640 chars ≈ ~924 tokens total
• Lazy-loaded: only router + relevant sub-command loaded per invocation
• Source/production dual version: detailed docs for humans, minimal instructions for AI

Testing

• 125-assertion test suite, all passing:
  • File existence (11 assertions)
  • Source WHY comments (5)
  • Production routing + rules (15)
  • Token budget (1)
  • Source logic completeness (39)
  • Production logic completeness (16)
  • Source ↔ Production consistency (36)
  • Edge case data (11)
  • Design document completeness (14)

Files Changed

• 14 files added, 865 lines total
• No core code modifications — all custom commands in .qwen/commands/

Welcome review and feedback!

[Critical] Hash calculation documentation is factually incorrect. The docs say "replace \ and / with -, lowercase" but the actual sanitizeCwd() replaces ALL non-alphanumeric characters with -, and lowercasing only happens on Windows (not Linux/macOS). E.g., /home/user/my.project → -home-user-my-project on Linux. The LLM will compute the wrong project directory path for any path with dots, spaces, or other special characters, breaking save/resume.

Suggested change

	| **Hash calculation** | Full cwd path, replace `\` and `/` with `-`, lowercase. E.g., `D:\code\qwen-code` → `d--code-qwen-code` |
	| **Hash calculation** | Full cwd path, replace ALL non-alphanumeric characters with `-`. On Windows only, also convert to lowercase. E.g., `/home/user/my.project` → `-home-user-my-project` (Linux) |

[wenshao]

[Critical] OS detection is unreliable on many shells. echo %OS% only works in CMD.exe (not PowerShell, the Windows default). $OSTYPE is bash/zsh-specific and will be empty in fish, PowerShell, nushell, etc. This means resume will generate wrong commands or fail entirely on many common shells.

Suggested change

	- `linux-*` → Linux
	Run `node -e "console.log(process.platform)"` for portable detection across all shells.
	- `win32` → Windows
	- `linux` → Linux
	- `darwin` → macOS

[wenshao]

[Critical] Production routing table maps -s, -r, -d to "Go to Step 3" but after validation there's no explicit flag-to-file mapping. The source version has | -s | chat-save.md | etc. The production version requires the LLM to infer which file to read from filenames alone, risking it reads the wrong sub-command.

Suggested change

	- Is name missing, empty, or whitespace only? → **Show Help immediately, STOP**
	Add after the existing table:
	| Flag | Sub-command file |
	| -s / --save | chat-save.md |
	| -r / --resume | chat-resume.md |
	| -d / --delete | chat-delete.md |

[wenshao]

[Critical] Production file omits Windows CMD fallback (source has both start pwsh ... and start cmd /k ...). Also Linux fallback has literal ... instead of full command xterm -e "qwen --resume <id>". Windows systems without PowerShell can't resume; the ... is ambiguous for the LLM.

Suggested change

	- Windows: `start pwsh -NoExit -Command "qwen --resume <id>"`
	- Windows: `start pwsh -NoExit -Command "qwen --resume <id>"` or `start cmd /k "qwen --resume <id>"`
	- macOS: `osascript -e 'tell app "Terminal" to do script "qwen --resume <id>"'`
	- Linux: `gnome-terminal -- qwen --resume <id>` (or `xterm -e "qwen --resume <id>"`)

— qwen3.6-plus via Qwen Code /review

[wenshao]

[Critical] Test asserts chatProd.includes('Architecture') but production chat.md has no Architecture section (stripped for token efficiency). This assertion always fails, causing 25/241 test failures and blocking CI.

Suggested change

	assert(chatProd.includes('Architecture') || chatProd.includes('architecture'), 'chat.md prod has Architecture section');
	Remove this assertion or update production chat.md to include an equivalent section header (e.g., "## Architecture & Routing"). Given the token budget, removing is preferred:
	// assert(chatProd.includes('Architecture') || chatProd.includes('architecture'), 'chat.md prod has Architecture section');

— qwen3.6-plus via Qwen Code /review

[wenshao]

[Suggestion] OS detection runs via shell subprocess on every /chat invocation, including /chat -l (list) and /chat -h (help) where it's completely unnecessary. Move OS detection into chat-resume.md only, where it's actually needed.

— qwen3.6-plus via Qwen Code /review

[wenshao]

[Suggestion] Linux terminal detection hardcodes gnome-terminal with no actual fallback detection. On non-GNOME Linux (KDE, Sway, WSL, containers), resume will fail. Add a command -v check:

Suggested change

	- Linux: `gnome-terminal -- qwen --resume <id>` (or `xterm -e ...`)
	- Linux: Run `command -v gnome-terminal && gnome-terminal -- qwen --resume <id> || command -v xterm && xterm -e "qwen --resume <id>" || echo "No supported terminal found. Run manually: qwen --resume <id>"`

[wenshao]

[Suggestion] CHAT-DESIGN.md section 8.3 states the build pipeline was abandoned ("因为两个版本差异不够大而放弃"), yet build.mjs is still shipped in the PR. This confuses future maintainers about whether the script is meant to be run. Consider removing it or moving to _archived/ with an explanation.

[lnxsun]

@wenshao Thank you for the detailed review! I have addressed all the issues you raised:

Changes Made

1. [Critical] Hash calculation documentation ✅

   • Fixed: Now correctly states "replace ALL non-alphanumeric characters with -" and "On Windows only, also convert to lowercase"
   • Added example: /home/user/my.project → -home-user-my-project (Linux)

2. [Critical] OS detection ✅

   • Changed from shell-specific echo %OS% / $OSTYPE to node -e "console.log(process.platform)"
   • Now works across all shells (PowerShell, CMD, bash, zsh, fish, nushell, etc.)

3. [Critical] Routing table ✅

   • Added explicit Sub-Command File column to the routing table
   • Now clearly maps -s → chat-save.md, -r → chat-resume.md, -d → chat-delete.md

4. [Critical] chat-resume.md commands ✅

   • Added Windows CMD fallback: start cmd /k "qwen --resume <id>"
   • Added full Linux terminal detection sequence with fallback to xterm
   • Explicitly instructed to use shell tool for execution

Additional Improvements

• Strengthened delete confirmation with Step 0 and visual emphasis (⚠️ icons, bold text)
• Updated CHAT-DESIGN.md to document the delete confirmation design rationale
• Removed deprecated build.mjs script

All 241 test assertions are passing. Please take another look when you have time. Thanks again for the thorough review! 🙏

[wenshao]

@tanzhenxin Looking for your call on the scope question for this PR.

Context:

• feat: add /chat command for saving, listing, resuming, and deleting named sessions #3105 was closed by you with the reasoning "don't want to keep two sets of interactions for the same behavior", pointing to feat(session): add rename, delete, and auto-title generation for session #3093 as the official direction
• This PR is @lnxsun's resubmission of the same /chat -s/-l/-r/-d functionality, reshaped as .qwen/commands/*.md file-based custom commands
• Technical side: The 4 Criticals from my earlier /review (wrong hash-calc docs, unreliable OS detection, routing table missing flag→file mapping, resume fallback gaps) are all fixed in 42ebcd8 — I just re-verified, no remaining blockers
• Scope side: But this PR still ships 13 files / 865 lines into the main repo's .qwen/, so anyone cloning the repo gets a /chat command set by default — parallel to feat(session): add rename, delete, and auto-title generation for session #3093's /rename, /delete, --resume <title> once that lands

Question: You closed #3105 over interaction duplication. Does the file-based form ("no core code touched") get around that concern, or does the same reasoning still apply?

The author has been diligent (7 rounds on #3105 plus this PR's test suite and cross-platform handling). Either way, a clear answer soon would help — so they don't keep investing in a direction that won't land.

[wenshao]

[Critical] The <hash> description here does not match the actual session storage implementation. Qwen Code stores project sessions under ~/.qwen/projects/<sha256(projectRoot)>/chats/ via getProjectHash(), not under a path-derived sanitized directory name. As written, /chat -s and /chat -r can look in the wrong directory and fail to find real sessions.

Suggested change

	| **Index path** | `.qwen/chat-index.json` (project root) |
	| **Hash calculation** | SHA-256 of the full project root path. On Windows only, normalize the path to lowercase before hashing. Session files live under `~/.qwen/projects/<sha256>/chats/`. |

— gpt-5.4 via Qwen Code /review

[lnxsun]

Thank you for catching this! The Critical fix is now in commit d3ed2753a.@wenshao

Changes Made

1. .qwen/commands/chat.md — Corrected Hash calculation row:

   • Before: Full cwd path, replace all non-alphanumeric characters with \-``
   • After: SHA-256 of the full project root path. On Windows only, normalize the path to lowercase before hashing. Session files live under \~/.qwen/projects//chats/``

2. .qwen/chat-src/commands/chat.md — Same fix in source version with updated rationale

3. .qwen/chat-src/commands/chat-save.md — Removed the incorrect path sanitization example (D:\code\qwen-code → d--code-qwen-code) and replaced with correct SHA-256 description

4. .qwen/chat-src/scripts/test.mjs — Updated test assertion [12e] to verify SHA-256 + Windows normalization instead of the old path-replacement logic

All 241 tests pass with the updated assertions.

[wenshao]

[Critical] newest .jsonl file is not a reliable definition of the current session. In a project with multiple active or recently resumed sessions, /chat -s <name> can bind the name to a different conversation than the one the user is saving, so a later resume may open the wrong chat.

Use a session identifier from the current runtime context instead of filesystem mtime, or explicitly redefine the feature as saving the most recent project session and update the help text to match.

— gpt-5.4 via Qwen Code /review

[wenshao]

[Suggestion] The read-index rule only defines the missing-file case. It does not say what to do when .qwen/chat-index.json exists but contains malformed JSON. That leaves room for the command to treat a parse failure like an empty index and overwrite existing mappings, which would silently lose saved names.

Please distinguish the cases explicitly: only ENOENT should fall back to {}; malformed JSON or other read errors should abort without writing.

— gpt-5.4 via Qwen Code /review

[lnxsun]

Thank you @wenshao for the latest review feedback! I've addressed both items:

1. [Critical] Unreliable session ID detection via mtime → Now prefers the session ID from the runtime context (the session the /chat command is running in). Falls back to newest .jsonl by mtime only when runtime context is unavailable, with an explicit warning: "Warning: Using most recent session by file time. If this is wrong, resume the target session first."

2. [Suggestion] Malformed JSON handling → Now distinguishes between ENOENT (→ empty {}) and malformed JSON (→ abort with error message, no overwrite). This prevents silently losing existing saved names when chat-index.json is corrupt.

Changes are in both .qwen/commands/chat-save.md and .qwen/chat-src/commands/chat-save.md.

[wenshao]

[Critical] This step now depends on a "runtime context" session ID that file-based custom commands do not appear to receive in this codebase. createSlashCommandFromDefinition() returns processed prompt text, but there is no command action API here that exposes the active chat UUID to Markdown commands, so the primary save path is not actually implementable as written.

Please either redesign the feature around data the file-command system can really access, or explicitly document a supported source for the active session ID instead of claiming the runtime context provides it.

— gpt-5.4 via Qwen Code /review

[wenshao]

[Critical] This confirmation flow assumes the Markdown command can stop, wait for a yes reply, and then resume the same deletion. In this repo, file commands submit prompt content, while resumable confirm_action is a separate built-in command return type and is explicitly unsupported in non-interactive mode. That means the documented two-step delete flow is not something the custom-command system can actually execute.

Please switch this to a supported interaction model (for example, an explicit second command / force flag) instead of a "wait for response, then continue" workflow.

— gpt-5.4 via Qwen Code /review

[wenshao]

[Suggestion] chat.md prod has Route section is asserted twice in a row here, so the suite counts one invariant twice without increasing coverage.

Please remove the duplicate assertion or replace it with a different missing check so the assertion count and maintenance burden stay honest.

— gpt-5.4 via Qwen Code /review

[wenshao]

[Critical] This assertion still requires production chat-save.md to explain that the fallback UUID comes from the .jsonl filename, but the current production file no longer says that. The bundled spec test therefore fails on the checked-in PR content (chat-save prod explains UUID comes from filename).

Please either restore that filename-without-extension wording in .qwen/commands/chat-save.md or update this assertion to match the intended production spec.

— gpt-5.4 via Qwen Code /review

[wenshao]

[Suggestion] The design doc says the suite contains 241 assertions, but the per-section counts in this table add up to 242, and the test file currently has a duplicated assertion. That makes the coverage claim internally inconsistent.

Please recompute the published total from the current script after removing or justifying the duplicate check.

This PR currently has merge conflicts (mergeStateStatus: DIRTY). Please rebase or merge the latest main and resolve the conflicts before the next review.

— gpt-5.5 via Qwen Code /review

[wenshao]

[Critical] The router assumes it can load another Markdown command file and replace {{name}}, but file-based commands are loaded as independent submit_prompt commands. The command processor substitutes the built-in {{args}} placeholder; it does not support a router dynamically loading another command file or templating a {{name}} placeholder.

This means /chat -s foo, /chat -r foo, and /chat -d foo can leave subcommands unexecuted or executed with literal {{name}}, so the unified /chat entry point is not implementable as written. Please either make each command independently invocable with {{args}}, or inline the subcommand logic into chat.md.

— gpt-5.5 via Qwen Code /review

[wenshao]

[Critical] This step deletes sessions/{{name}}.jsonl, which contradicts the PR's stated safety contract that /chat -d removes only the saved name from the index and preserves the underlying session history.

If this file exists, deleting a name can destroy chat data and also breaks the shared-reference guarantee where multiple names may point to the same underlying session. Please remove the file deletion step and only delete the {{name}} entry from .qwen/chat-index.json, with an explicit note that the session history file is not deleted.

Suggested change

	4. Delete file `sessions/{{name}}.jsonl` (if exists).
	5. Write `.qwen/chat-index.json`.
	6. Done. Show: `✅ Session "{{name}}" removed from saved sessions index. The actual session history file is NOT deleted.`

— gpt-5.5 via Qwen Code /review

[wenshao]

@lnxsun Quick status summary so the next round is unblocked:

Three things still need to land before this can merge:

1. Merge conflict. mergeStateStatus: DIRTY — please rebase onto the latest main and resolve.

2. .qwen/commands/chat.md:46 — [Critical] router design is not implementable. The unified /chat entry tries to load another Markdown command file and template {{name}}, but file-based commands are loaded as independent submit_prompt commands. The command processor only substitutes the built-in {{args}} placeholder; it does not support a router dynamically loading another command file. So /chat -s foo, /chat -r foo, /chat -d foo will either leave subcommands unexecuted or run with a literal {{name}}. Please either make each subcommand standalone, or move the routing into a single command body that handles all flags inline.

3. .qwen/commands/chat-delete.md:15 — [Critical] contradicts the stated safety contract. This step deletes sessions/{{name}}.jsonl. The PR description promises /chat -d removes only the saved name from the index and preserves the underlying session history. The current step also breaks the shared-reference guarantee where multiple names can point to the same underlying session. Please remove the file deletion step — delete only the {{name}} entry from .qwen/chat-index.json, and add an explicit note that the session history file is not deleted.

Once these three are addressed I'll do the next review pass. Thanks for the patience on this one.

[wenshao]

[Critical] This points the command at ~/.qwen/projects/<hash>/chats/, but current session storage does not use the SHA-256 hash for project chat files. Storage.getProjectDir() builds the project directory from sanitizeCwd(projectRoot), and chat recording stores transcripts under that project directory. As written, /chat -s and /chat -r can look in the wrong directory and fail to find existing sessions.

Please update the command specs and matching source/tests/docs to use the same sanitized project directory convention as Storage.getProjectDir(), not the SHA-256 project hash.

— gpt-5.5 via Qwen Code /review

[wenshao]

[Critical] The router extracts the name as everything after the flag before handling -y / --force. For the documented /chat -d my-session -y form, the extracted name becomes my-session -y, so validation fails before chat-delete.md can skip confirmation.

Parse delete arguments by separating force flags from the positional session name before validation: treat the first non-force token after -d as the name, accept -y / --force as flags, and reject any extra non-force tokens.

— gpt-5.5 via Qwen Code /review

[wenshao]

[Critical] The PR's own validation script fails on the checked-in files. Running node .qwen/chat-src/scripts/test.mjs reports Production: 9297 chars, but this assertion still requires < 9000; it also fails the two no-session wording assertions later in the file because the command specs say No session found. Start a conversation first. while the test only accepts other phrases.

Either reduce the production command size below the asserted budget or intentionally update the threshold, and align the no-session assertions with the actual command wording (or change the command wording to match the test).

— gpt-5.5 via Qwen Code /review

[wenshao]

[Critical] The command specs still point session lookup at ~/.qwen/projects/<hash>/chats/ and define <hash> as SHA-256 of the project root. Current chat recordings are stored under Storage.getProjectDir()/chats, and Storage.getProjectDir() uses sanitizeCwd(projectRoot), not getProjectHash().

As written, /chat -s can fail to find the current session and /chat -r can reject valid saved sessions because both commands inspect the wrong directory. Please update the command specs/source/tests/docs to use the actual ~/.qwen/projects/<sanitizeCwd(projectRoot)>/chats/ convention, with sanitizeCwd lowercasing on Windows and replacing all non-alphanumeric characters with -.

Review summary

Multi-agent review (4 agents: prior-comment verification, fresh Correctness+Security, 3am-oncall, Maintainer) on HEAD 2fc927f3. Substantial iteration history acknowledged — author has shipped 15 commits and addressed reviewer feedback diligently. 28 of 34 prior open inline comments are demonstrably addressed in HEAD; the remaining 6 are noted in this review (some inline, some called out below).

Verdict: Request changes — 6 Critical findings new (not raised in any prior round), plus 7 Suggestions. The Critical findings cluster in three areas: (a) the cross-platform resume terminal launch is broken or under-specified; (b) the project-belongs verification added in response to earlier feedback is a no-op because it checks a field name that doesn't exist in the actual session record schema; (c) several documented mechanisms reference fictional infrastructure (e.g., $QWEN_PROJECTS_DIR env var, generic "runtime context").

Why this round still has Critical findings

The earlier review threads focused largely on individual symptoms — wrong path, wrong field, wrong format. This pass took the file as a whole spec and tested it against the real codebase: read packages/core/src/services/sessionService.ts for actual session record shape, read packages/core/src/config/storage.ts for real env-var precedence, ran node .qwen/chat-src/scripts/test.mjs, and traced the macOS shell-quoting end-to-end. Most prior Criticals were valid and are now fixed; the new Criticals come from cross-checking the spec against the runtime it claims to invoke.

Prior comments status

• ADDRESSED (28): hash calculation, OS detection, routing flag-to-file mapping, Architecture test gate, gnome-terminal hardcode, build.mjs in scripts/, <hash> description, mtime-newest unreliability, malformed JSON handling for save/list/resume/delete, runtime context dependency, confirm-flow design, duplicate Route assertion, UUID-from-filename test, chat-delete preserving file, -y/--force parsing in router, ID validation against shell metacharacters, EOF artifact, hyphenated UUID acceptance, QWEN_RUNTIME_DIR priority documented, settings.json secret-leak removed, project-dir preservation in resume, project-belongs check added (broken — see Critical finding inline), trailing-token rejection, etc.
• STILL PRESENT (1): CHAT-DESIGN.md internal inconsistency — see inline at chat-src/CHAT-DESIGN.md:287.
• PARTIAL (3):
  • chat-resume.md production omits the Windows CMD fallback. Source chat-src/commands/chat-resume.md:71-72 documents start cmd /k ... as fallback for systems without PowerShell, production has only start pwsh .... Windows machines without PowerShell available will fail to resume. (The Linux xterm fallback was correctly fixed.)
  • Source chat-src/commands/chat.md:110 and chat-src/commands/chat-delete.md:9 still describe paths as ~/.qwen/projects/<hash>/chats/ while production uses <sanitizeCwd>. Source-of-truth docs disagree with production — see inline at chat-src/commands/chat.md:110.
  • {{name}} placeholder substitution: the qwen-code command processor only auto-substitutes the built-in {{args}} token. Sub-command files use {{name}} ~12 times and rely on the LLM to substitute the parsed name when the router instructs "Read corresponding sub-command file and execute". This works in practice with capable models but isn't documented as a guarantee. Consider replacing {{name}} in sub-commands with prose like "the parsed name from {{args}}".

Notes

• CI is all_pending (12/12 checks queued/running) — this review is based on static analysis only; smoke-test results may change the picture.
• Token-budget claim discrepancy: PR description says "~924 tokens / ~2,640 chars". Live test reports Production: 11844 chars. The headline understates production size by ~4×.
• Live test result: node .qwen/chat-src/scripts/test.mjs → 240/240 pass (PR description says "125-assertion test suite" — actual is 240).

[wenshao]

[Critical] Step 4 says "Parse JSON and verify project field matches the current project directory." The actual qwen-code session record has no project field — see packages/core/src/services/sessionService.ts:592 which compares getProjectHash(firstRecord.cwd) === this.projectHash. The real field is cwd, and the real comparison hashes both sides via getProjectHash (SHA-256 of sanitized path).

With the field absent, an LLM following the spec literally will either always reject (undefined === <projectDir> → false → "Session belongs to another project. Aborted.") or silently skip the check; either way the safety check the prior review asked for is dead code. The ADDRESSED count above is one fewer than it appears.

Additional gaps in the same step (relevant once the field name is fixed):

• Empty file (zero bytes — common during interrupted writes): no defined behavior. Should be "Session file empty (likely interrupted save). Aborted."
• First record is not valid JSON (truncated mid-record from a crash): no defined behavior.
• First record is a system message lacking cwd: no defined behavior.

Suggested fix:

4. **Verify session belongs to current project**: Read the first JSON line of `<runtimeBase>/projects/<sanitizeCwd>/chats/<id>.jsonl`. 
   - File missing → "Session file missing", stop.
   - File 0 bytes → "Session file empty (likely interrupted save). Aborted."
   - First line not valid JSON → "Session file corrupt at line 1. Aborted."
   - JSON has no `cwd` field → "Session record missing project context. Aborted."
   - JSON `cwd` field, after running through the same sanitizeCwd as this command, ≠ current project's `<sanitizeCwd>` → "Session belongs to another project. Aborted."

Alternatively (simpler), drop the in-LLM verification entirely and rely on the path itself: the file is at <runtimeBase>/projects/<sanitizeCwd>/chats/<id>.jsonl, so the path already encodes the project bucket. If <id>.jsonl exists at the current project's <sanitizeCwd> directory, it belongs to this project by construction.

[Critical] macOS osascript line is malformed regardless of <projectRoot> content:

osascript -e 'tell app "Terminal" to do script "cd '<projectRoot>'; qwen --resume <escaped_id>"'

POSIX shells do not nest single quotes. The first ' immediately after cd terminates the outer -e argument, splices in unquoted <projectRoot> (so spaces become argv splits), then reopens. As literally templated, this command produces a shell parse / osascript syntax error or — worse — silent path truncation on macOS hosts where $HOME contains a space (the default /Users/Alice Smith/... pattern with first+last name accounts).

A literal-following LLM cannot produce a working command from this spec.

Suggested fix — use double-quote outer with explicit escaping inside, and POSIX-shell-quote <projectRoot> (single-quote wrapped, internal ' rewritten as '\''):

osascript -e "tell app \"Terminal\" to do script \"cd <projectRootEscaped> && qwen --resume <id>\""

Where <projectRootEscaped> is the result of replacing every ' in <projectRoot> with '\'' and wrapping the whole string in '…'. Apply the same treatment to the Linux line (bash -c '…') and the Windows line (PowerShell single-quote inside "…").

Alternatively: write the AppleScript to a temp file (mktemp /tmp/qwen-resume.XXXXXX.scpt) and run osascript /tmp/qwen-resume.XXXXXX.scpt — sidesteps shell quoting entirely.

[Critical] <projectRoot> is referenced 3× in Step 6 (Windows / macOS / Linux) but never defined or sourced in any of the .md files. The LLM has to guess where it comes from:

• Current qwen process cwd? Tautological — the new terminal would be opening in the same directory the user is already in.
• Decoded from <sanitizeCwd>? Impossible — sanitizeCwd() is not invertible (D:\code\qwen-code → d--code-qwen-code, can't recover the original).
• The cwd field of the first record in <id>.jsonl? Correct, but the spec never says so.

Suggested fix — add Step 4.5 (or fold into Step 4 once the cwd/project issue is fixed):

4.5. Set <projectRoot> = the cwd field of the first JSON record in <id>.jsonl. Verify it exists on disk. Missing → "Error: original project directory <projectRoot> no longer exists. Aborted."

This also enables a useful safety check: if the saved session was originally in a directory that's been deleted/moved, the user gets a clean error instead of a terminal that flickers and dies when cd fails silently.

[wenshao]

[Critical] OS detection runs node -e "console.log(process.platform)" then routes by string. WSL2 returns linux, so the router routes to chat-resume.md's Linux branch — gnome-terminal -- bash -c "…" or xterm -e "…". Inside WSL these either fail (no X display) or pop up an X window the user can't easily reach, and qwen --resume <id> runs in that lost window.

WSL is a non-trivial slice of "Windows" qwen-code users. Repro path: "I /chat -r foo, nothing happens." No log to inspect (see also chat.md re: missing breadcrumbs). Hours of debug.

Suggested fix — when process.platform === 'linux', additionally test for WSL:

If platform == 'linux':
  Read /proc/version. If it contains 'Microsoft' or 'WSL' (case-insensitive),
  treat as Windows for the resume branch — use Windows Terminal:
    wt.exe -d '<projectRoot>' -- qwen.exe --resume <id>
  (or fall back to: cmd.exe /c start cmd /k "cd /d <projectRoot> && qwen --resume <id>")

Document this branch in chat-resume.md Step 6 alongside the existing platform list.

[wenshao]

[Critical] The Runtime Base Resolution priority list documents $QWEN_PROJECTS_DIR as a fallback after $QWEN_RUNTIME_DIR. QWEN_PROJECTS_DIR does not exist in the qwen-code codebase — grep -rn QWEN_PROJECTS_DIR packages/ returns zero hits. The same fictional precedence appears in chat-save.md:13, chat-resume.md:17, chat-delete.md, and the chat-src/ source counterparts (5+ files in lockstep).

The real runtime base resolution is in packages/core/src/config/storage.ts:103-119:

1. QWEN_RUNTIME_DIR env var (matches the doc).
2. setRuntimeBaseDir(path) — driven by the advanced.runtimeOutputDir settings key.
3. ~/.qwen default.

The advanced.runtimeOutputDir settings key is invisible to the LLM at command-execution time (it would have to read ~/.qwen/settings.json — already rejected as a credential-leak risk in earlier rounds).

Impact: any user who configures advanced.runtimeOutputDir in settings will have sessions stored under the configured base, but /chat -s|-l|-r|-d will look under ~/.qwen (because the LLM follows the docs and only checks two env vars) and report "No session found." These two flows silently disagree.

Suggested fix — replace $QWEN_PROJECTS_DIR references with reality:

Runtime Base Resolution (in priority order):
- $QWEN_RUNTIME_DIR (if set)
- ~/.qwen (default fallback)

Note: If the user has set `advanced.runtimeOutputDir` in settings.json, sessions
are under that path instead. /chat commands cannot read settings.json (credential
leak risk) and will not find those sessions. Document this limitation.

Fix in 5 files: chat.md, chat-save.md, chat-resume.md (production) and the chat-src counterparts.

via Qwen Code /review

[wenshao]

[Suggestion] Step 3 says for save/resume: "Filter out any flags first, the first remaining token is the name." There's no definition of "any flag" here — only -y/--force are listed (and only for delete). /chat -s my-name --garbage is ambiguous: treat --garbage as a flag (filter, accept my-name, ignore typo)? Or extra non-flag token (reject)? Different LLM runs will answer differently, especially smaller ones.

Similarly /chat -s my-name -y — -y is documented as a delete-only option, but "filter out any flags" makes save/resume silently swallow it.

Suggested fix — make the rule symmetric with delete's explicit allowlist:

For save/resume: reject any token starting with `-` after the flag.
  Save and resume have no options.
  Error: "Unexpected token: <token>. /chat -s|-r takes only a single name."
For delete: allow only `-y` / `--force` after the name.

[wenshao]

[Suggestion] This source-of-truth doc still describes paths as ~/.qwen/projects/<hash>/chats/ with the SHA-256 calculation, while production uses <sanitizeCwd> (replace non-alphanumerics with -, lowercase on Windows). Same drift in .qwen/chat-src/commands/chat-delete.md:9.

Future-maintainer hazard: source docs are billed in CHAT-DESIGN.md sec 8.3 as "the WHY explanation; production is the compressed copy". A reader treats the source as authoritative and re-introduces the SHA-256 path layout (which was the bug fixed in commit d3ed2753a). The path-derived-hash design has been gone for ~10 commits but the source files weren't updated alongside production.

Suggested fix — sync source to match production reality, or add a script (similar to the archived build.mjs but minimal) that diffs each source file's path/identifier mentions against its production counterpart and fails CI if they drift.

via Qwen Code /review

[wenshao]

[Suggestion] Design doc has drifted from production in three measurable ways:

1. sec 5.1 (line ~188) — language detection still documented as reading ~/.qwen/settings.json's general.language field. Production switched to Intl.DateTimeFormat().resolvedOptions().locale (correctly, after the credential-leak concern in earlier rounds). The doc never updated.
2. sec 7.2 (~line 267-279) — "实测" table claims chat.md = 4504 chars, total = 8028, "Token 预算限制已调整为 < 9000 字符". Reality: chat.md = 5752 chars, total = 11844, live test asserts < 12000. Off by ~50% on chat.md, +47% on total, and the budget limit is wrong.
3. sec 8.1 (line 287, this anchor) — claims "12 个维度, 241 个断言". Per-row counts in the table sum to 242. Live test reports Total: 240.

Future-maintainer hazard: someone reading CHAT-DESIGN.md as the architecture authority picks up the old language-detection approach (settings.json reads — already rejected), or believes the token budget is half what it actually is when sizing a new sub-command.

Suggested fix:

• Either auto-generate sec 7.2 (and the assertion table at 287) from a small script run in CI, or replace the numeric claims with a link to test.mjs and the live output.
• Update sec 5.1 to describe the actual Intl.DateTimeFormat mechanism. Add a paragraph explaining why settings.json was rejected.

via Qwen Code /review

[wenshao]

[Suggestion] Token budget is the only quantitative assertion in the suite, and it has been raised three times: 4000 → 9000 → 12000, each time with a comment of the form "Note: Budget increased to N to accommodate ...". The current limit (12000) is ~2% above the actual size (11844). The other 239 assertions are all String.prototype.includes() substring checks against the raw markdown — they catch keyword deletions but not logic regressions.

Future-me adding /chat -e (whose markdown will easily push past 12000) will be told to bump the limit. There's no real budget enforcement — the test only enforces "I haven't yet noticed I crossed the line". Calling this a "125-assertion test suite, all passing" (per PR description) overstates rigor.

Also: PR description says "~924 tokens / ~2,640 chars". Live size is 11844 chars. The headline understates by ~4×.

Suggested fix:

• Pin the budget at a value that requires real engineering to maintain (e.g., current size + 5%) AND require a CHAT-DESIGN.md sec 7.2 update in the same PR if it moves.
• Or remove the budget assertion entirely and replace the marketing claim in PR description / README with "smoke test for keyword presence". Don't ship a moving goalpost dressed as enforcement.

via Qwen Code /review

[wenshao]

[Suggestion] Stale committed snapshot. Current live run produces 240 assertions and reports Production: 11720 chars; this committed file says 241 assertions and Production: 7177 chars, with old labels like "specifies hash calculation" / "explains path→hash transformation" that no longer exist in test.mjs. Nothing in the repo diffs the live output against this file — pure residue.

Future-maintainer hazard: someone sees the file, assumes it's a regression baseline, runs the suite, gets a different output, can't tell whether they broke something or whether the file was simply stale.

Suggested fix — pick one:

• Delete test-output.txt entirely. The live test prints the same info; you don't need a committed snapshot.
• Add a CI check that runs node .qwen/chat-src/scripts/test.mjs > .qwen/chat-src/scripts/test-output.txt and asserts no diff, making this a real regression baseline.

Don't ship both of nothing.

@wenshao 感谢第二轮review！我已经修复了所有6个Critical问题：

已修复的问题

#1 项目归属验证字段错误

修复：使用cwd字段而非project字段，获取其值作为<projectRoot>，然后应用sanitizeCwd比较。
同时添加了边界情况处理：

• 文件0字节（中断写入）→ "Session file empty (likely interrupted save). Aborted."
• JSON解析失败 → "Session file corrupt at line 1. Aborted."
• 无cwd字段 → "Session record missing project context. Aborted."
• 项目目录不存在 → "Error: original project directory '' no longer exists. Aborted."

#2 macOS osascript语法错误

修复：使用双引号外层，内部的引号正确转义：
osascript -e "tell app \"Terminal\" to do script \"cd '<projectRoot>' && qwen --resume <id>\""

#3 未定义

修复：从session JSON记录中读取cwd字段作为<projectRoot>，并验证目录存在。

#4 WSL未处理

修复：在OS检测中，当platform为linux时，额外读取/proc/version检查是否包含"Microsoft"或"WSL"。如果是，resume命令使用Windows Terminal或CMD。

#5 $QWEN_PROJECTS_DIR不存在

修复：移除$QWEN_PROJECTS_DIR，使用真实的优先级：

• $QWEN_RUNTIME_DIR (if set)
• ~/.qwen (default)
  添加说明：如果用户配置了advanced.runtimeOutputDir，sessions存储在该路径，/chat命令无法读取settings.json会找不到这些sessions。

#6 Windows CMD fallback缺失

修复：在resume命令中添加了CMD fallback：
start cmd /k "cd /d <projectRoot> && qwen --resume <id>"

建议问题的处理

1. Flag定义：已明确save/resume拒绝任何以-开头的token
2. 源文件路径：已更新chat-src/commands/chat-delete.md中的路径描述

测试全部通过 (240/240)。

[wenshao]

⚠️ CI check failing: Test (ubuntu-latest, 24.x). This review is based on static analysis of documentation files only.

Additional findings not mapped to diff lines:

• [Suggestion] chat-delete.md step ordering: Production version asks for confirmation (Step 0) before validating the name (Step 1). Source file validates first, then confirms. Consider reordering production to match source.
• [Suggestion] Token budget ceiling: Budget raised 4× (4000→14000) with no documented hard limit. Consider defining a maximum (e.g., 15000 chars) and stating what to remove when approaching it.

[wenshao]

[Critical] Linux native command has a stray trailing single quote. <terminal> -- bash -c "cd '<projectRoot>' && qwen --resume <id>'" — the ' after <id> is unmatched, causing bash to hang indefinitely waiting for input with no error output. The source file (chat-src/commands/chat-resume.md) correctly omits this stray quote.

Suggested change

	- Linux (native): detect terminal with `command -v` (gnome-terminal, xterm, alacritty, kitty in order), then run: `<terminal> -- bash -c "cd '<projectRoot>' && qwen --resume <id>'"`
	- Linux (native): detect terminal with `command -v` (gnome-terminal, xterm, alacritty, kitty in order), then run: `<terminal> -- bash -c "cd '<projectRoot>' && qwen --resume <id>"`

[wenshao]

[Critical] WSL resume command passes a Linux-style <projectRoot> (e.g., /home/user/project) to cmd.exe /c cd /d, which expects a Windows path. The cwd field from the JSONL session file stores the Linux-native path. cd /d will fail with "The system cannot find the path specified." Additionally, qwen is typically installed within the WSL distribution and not in Windows CMD's PATH.

Consider using wslpath -w "<projectRoot>" to convert to a Windows path, or launching within the WSL context (e.g., wsl.exe -e bash -c "cd '<projectRoot>' && qwen --resume <id>").

— glm-5.1 via Qwen Code /review

[wenshao]

[Critical] <projectRoot> is sourced from the JSONL cwd field (step 4) and interpolated into shell commands without shell-safety validation. Two concrete problems:

1. POSIX platforms (macOS line 17, Linux line 19): cd '<projectRoot>' — a path containing a single quote (e.g., /Users/O'Brien/project) breaks out of single-quote wrapping.
2. Windows CMD (line 16): cd /d <projectRoot> — completely unquoted, so paths with spaces (e.g., C:\Program Files\project) cause command splitting.

The session ID <id> is properly validated (^[a-fA-F0-9-]+$), but <projectRoot> has no equivalent check. Consider adding a validation step that rejects <projectRoot> if it contains shell metacharacters, or documents per-platform escaping rules.

— glm-5.1 via Qwen Code /review

[wenshao]

[Suggestion] The incremental diff introduces 6 major new behaviors (malformed JSON handling, WSL detection, cwd-based project verification, argument validation, runtimeBase resolution, locale detection), but this change only updates the token budget (11000→14000). Zero new assertions guard any of these features — they could be silently removed or broken while all 240 assertions pass.

Consider adding keyword-presence assertions for new behaviors (e.g., assert production files contain malformed, WSL, /proc/version, cwd in project-context, Unexpected token, runtimeBase), consistent with the existing test style.

— glm-5.1 via Qwen Code /review

[wenshao]

[Suggestion] chat-save selects the newest .jsonl by mtime without verifying the session belongs to the current project. The same diff added project-identity verification to chat-resume (steps 4–5: read JSONL cwd, compare via sanitizeCwd), but chat-save has no equivalent check. When sanitizeCwd collides across project paths, chat-save can store a session ID from a different project — and chat-resume will then reject it with "Session belongs to another project."

Consider adding: after selecting the newest .jsonl, read its first line and verify cwd matches the current project before saving.

— glm-5.1 via Qwen Code /review

[wenshao]

[Suggestion] Project-identity verification uses sanitizeCwd() comparison, but the core SessionService uses getProjectHash() (SHA-256) for all project-ownership checks. sanitizeCwd is not collision-resistant — two different paths can produce the same sanitized form (e.g., /home/a-b/c and /home/a/b-c both become -home-a-b-c).

Consider computing SHA-256 via node -e "require('crypto').createHash('sha256').update(process.argv[1]).digest('hex')" '<projectRoot>' to match the core's approach, or document this as a known limitation of file-based commands.

@wenshao 感谢您的第三轮review！以下是所有修改的详细说明：

Critical 修复

1. Linux命令末尾多余单引号

问题: Linux native命令 <terminal> -- bash -c "cd '<projectRoot>' && qwen --resume <id>'" 末尾有未闭合的单引号，导致bash挂起。

修复: 移除末尾的单引号：

<terminal> -- bash -c "cd '<projectRoot>' && qwen --resume <id>"

2. WSL路径转换

问题: JSONL中存储的是Linux原生路径（如/home/user/project），传给Windows cmd.exe的cd /d会失败。

修复: 添加路径转换步骤：

wslpath -w "<projectRoot>"  # 转换为Windows路径
cmd.exe /c "start cmd /k cd /d \"<windowsPath>\" && qwen --resume <id>"

3. projectRoot shell安全验证

问题: session ID有验证，但projectRoot（来自cwd字段）没有安全检查。路径含单引号或空格会导致命令失败。

修复: 添加安全检查步骤（Step 6）：

• POSIX: 拒绝 $ ` ; |, >, <, &, (, ), 空格
• Windows: 额外检查 ^ 和 %

---

Suggestion 修复

1. chat-delete步骤顺序

问题: 生产文件先确认后验证，源文件先验证后确认。

修复: 重排为：验证name → 读取index → 确认（条件触发）→ 删除

2. Token预算硬性上限

问题: 预算从4000涨到14000，无硬性上限。

修复: 添加硬性上限15000 chars：

console.log('  Hard limit: 15000 chars. If approaching limit, remove verbose explanations...');
assert(totalProd < 15000, 'Total below hard limit (15000 chars)');

3. 新功能关键词断言

问题: 新增功能无测试守护，可能被静默破坏。

修复: 添加新测试维度 [8.5]，验证关键词存在：

• malformed/corrupt, WSL, cwd, Unexpected token, runtimeBase, wslpath, unsafe

4. chat-save项目验证

问题: chat-save缺少项目验证，与chat-resume不一致。

修复: 在Step 5添加验证：

• 读取选中.jsonl第一行，检查cwd字段
• 应用sanitizeCwd比较，跨项目则拒绝

5. sanitizeCwd限制说明

问题: 使用sanitizeCwd vs 核心的getProjectHash(SHA-256)不同。

修复: 在源文件中添加说明：

Limitation note: chat-resume uses sanitizeCwd() for project comparison. The core SessionService uses SHA-256 hash (getProjectHash()). sanitizeCwd is not collision-resistant. This is a known limitation of file-based commands.

[Critical] Step 6 shell-safety validation rejects $ ` ; | > < & ( ) and spaces, but does not reject single quotes ('). However, step 8's Linux command wraps <projectRoot> in single quotes (cd '<projectRoot>'), and the macOS command also relies on single-quote wrapping. A path containing a single quote (e.g., /Users/O'Brien/project) will prematurely terminate the single-quoted string, producing a broken or potentially dangerous shell command.

Suggested fix: Add ' (single quote / apostrophe) to the POSIX metacharacter rejection list in step 6.

Suggested change

	6. **Validate projectRoot for shell safety**: If <projectRoot> contains any shell metacharacters (`$`, `` ` ``, `;`, `|`, `>`, `<`, `&`, `(`, `)`, spaces), reject: "Error: Session path contains unsafe characters. Aborted."
	6. **Validate `projectRoot` for Shell Safety**: Check `<projectRoot>` for metacharacters. If it contains any of `$` ` ` `;` `|` `>` `<` `&` `(` `)` `'` (or spaces — see note), output "Error: Session path contains unsafe characters. Aborted." and stop. For Windows: also check for `^` and `%`.

[wenshao]

[Critical] The WSL wt.exe command template has a stray trailing double quote: wt.exe -d "<windowsPath>" -- qwen.exe --resume <id>". The " after <id> is unmatched and will be appended to the session ID argument, causing qwen.exe --resume to receive an incorrect ID and fail.

Suggested fix: Remove the trailing ":

Suggested change

	- Use: `cmd.exe /c "start cmd /k cd /d \"<windowsPath>\" && qwen --resume <id>"` or prefer `wt.exe -d "<windowsPath>" -- qwen.exe --resume <id>"`
	wt.exe -d "<windowsPath>" -- qwen.exe --resume <id>

— pai/glm-5.1 via Qwen Code /review

[wenshao]

[Critical] Step 6 rejects paths containing spaces, but all platform command templates already properly quote the path (PowerShell: cd '<projectRoot>', CMD: cd /d \"<projectRoot>\", macOS/Linux: cd '<projectRoot>'). Spaces are not a shell injection vector — they are a normal path character handled by quoting. Rejecting spaces makes /chat resume unusable for projects with spaces in their directory path (e.g., ~/My Project/, C:\Program Files\project), which are extremely common on macOS and Windows.

Suggested fix: Remove spaces from the POSIX metacharacter rejection list. Keep only truly dangerous shell metacharacters ($ ` ; | > < & ( ) '):

Suggested change

	6. **Validate projectRoot for shell safety**: If <projectRoot> contains any shell metacharacters (`$`, `` ` ``, `;`, `|`, `>`, `<`, `&`, `(`, `)`, spaces), reject: "Error: Session path contains unsafe characters. Aborted."
	6. **Validate `projectRoot` for Shell Safety**: Check `<projectRoot>` for metacharacters. If it contains any of `$` ` ` `;` `|` `>` `<` `&` `(` `)` `'`, output "Error: Session path contains unsafe characters. Aborted." and stop. For Windows: also check for `^` and `%`.

[wenshao]

[Critical] The macOS sed escaping sed "s/'/\\\\'/g" produces \' as the replacement for '. However, inside a bash single-quoted string, \' is not a valid escape — backslash has no special meaning inside single quotes, so ' still terminates the string. The correct bash idiom for embedding a single quote inside a single-quoted string is '\'' (end-quote, escaped-quote, reopen-quote).

If Finding 1 is adopted (adding ' to the step 6 rejection list), this sed escaping becomes unnecessary and can be removed. If single-quote paths must be supported, the sed replacement must produce '\\'' instead of \':

Suggested change

	- macOS: `osascript -e "tell app \"Terminal\" to do script \"cd '$(echo "<projectRoot>" | sed "s/'/\\\\'/g")' && qwen --resume <id>\""`
	cd '$(echo "<projectRoot>" | sed "s/'/'\\\\''/g")' && qwen --resume <id>

[wenshao]

[Suggestion] Duplicate step number: both "Write to Index" and "Confirm" are numbered ### 6. The production file correctly numbers them 6 and 7, so source and production are inconsistent.

Suggested change

	### 6. Confirm
	### 7. Confirm

[wenshao]

[Suggestion] Section [8.5] assertions are keyword-presence checks that give false confidence. Key issues:

1. prodAll.includes('token') matches unrelated contexts ("first token", "Token budget") — use prodAll.includes('Unexpected token') without the fallback
2. prodAll.includes('-w') is too broad as a fallback for wslpath — use prodAll.includes('wslpath') alone
3. prodAll.includes('cwd') && prodAll.includes('project') is nearly vacuous — use prodAll.includes('belongs to another project')
4. prodAll.includes('unsafe') || prodAll.includes('metacharacter') is weak — use prodAll.includes('unsafe characters') && prodAll.includes('Aborted')

— pai/glm-5.1 via Qwen Code /review

[wenshao]

[Suggestion] The "Runtime Base Resolution + sanitizeCwd + runtimeOutputDir" block at the end of this file is already present verbatim in chat.md's Common Rules. Since chat.md is always loaded before sub-commands, this duplicates ~300 chars. With the total at 13814/15000 chars (only 1186 chars of headroom), removing the duplicate from chat-save.md and chat-resume.md would free ~600 chars for future additions.

Suggested fix: Replace the trailing block with: (See chat.md Common Rules for runtimeBase and sanitizeCwd details.)

— pai/glm-5.1 via Qwen Code /review

[wenshao]

[Suggestion] Step 5 reads the .jsonl first line for project verification but only handles the case where the cwd field is missing. It does not define behavior when the first line is not valid JSON. chat-resume step 4 explicitly handles this ("Session file corrupt at line 1. Aborted."), but chat-save has no corresponding spec. A corrupt .jsonl would cause unpredictable LLM behavior.

Suggested fix: Add to step 5: "If first line is not valid JSON → skip verification (corrupt session, allow save with warning)" or "First line not valid JSON → Aborted", consistent with chat-resume.

— pai/glm-5.1 via Qwen Code /review

[wenshao]

[Suggestion] The source file uses a markdown table for platform-specific commands, but the macOS row contains a | pipe character inside the sed command. This pipe is interpreted as a markdown table column separator, splitting the macOS command across an extra column and making it render as garbled text. The production file is unaffected (uses flat list format).

Suggested fix: Escape the pipe as \| in the markdown table, or switch the source to the same flat list format used in production.

[Critical] projectRoot shell metacharacter blocklist is incomplete — allows arbitrary command execution

Step 6 blocks $, `, ;, |, >, <, &, (, ), spaces. But newline (\n), double-quote ("), single-quote ('), and backslash (\) are missing.

Three concrete injection vectors:

• Linux: \n inside bash -c "cd '<projectRoot>' && ..." acts as a command separator — a newline in the path executes arbitrary commands
• macOS: " in echo "<projectRoot>" closes the double-quote context, allowing injection via the osascript command
• All POSIX: ' breaks cd '<projectRoot>' single-quote delimiters — e.g., /x'; touch /tmp/pwned; echo '/x injects touch /tmp/pwned

Attack chain: a crafted .jsonl file with a malicious cwd field in ~/.qwen/projects/<sanitizeCwd>/chats/ enables RCE when the user runs /chat -r.

Suggested change

	6. **Validate projectRoot for shell safety**: If <projectRoot> contains any shell metacharacters (`$`, `` ` ``, `;`, `|`, `>`, `<`, `&`, `(`, `)`, spaces), reject: "Error: Session path contains unsafe characters. Aborted."
	6. **Validate projectRoot for shell safety**: <projectRoot> must match `^[a-zA-Z0-9/._-]+$` — reject any path containing characters outside this set. Reject: "Error: Session path contains unsafe characters. Aborted."
	- For Windows: also reject `^`, `%`, `\`

[wenshao]

[Suggestion] The limitation note states "The core SessionService uses SHA-256 hash (getProjectHash)" — but Storage.getProjectDir() (which determines the actual session storage path) uses sanitizeCwd, not getProjectHash. Both the chat commands and the core code use the same function; there is no architectural mismatch.

This factual error could mislead a future contributor into believing there's a real gap between layers and wasting time "fixing" something that isn't broken.

Suggested change

	**Limitation note**: chat-resume uses sanitizeCwd for project comparison. The core SessionService uses SHA-256 hash (getProjectHash). sanitizeCwd may have collisions for unusual paths, but this is a known limitation of file-based commands.
	**Limitation note**: chat-resume uses sanitizeCwd for project comparison. Both these commands and the core SessionService use `sanitizeCwd` for session directory resolution. The collision risk (e.g., `/home/a-b/c` and `/home/a/b-c` both produce `home-a-b-c`) is inherent in the sanitizeCwd algorithm itself, not a mismatch between layers.

[wenshao]

[Suggestion] chat-resume is the only sub-command missing malformed JSON handling for chat-index.json. The other three all specify: "JSON parse error → output 'chat-index.json is malformed. Fix it manually.' and stop." If the index file is corrupted, chat-resume behaves unpredictably instead of showing a clear error.

Suggested change

	2. Look up ID in index (`.qwen/chat-index.json` in project root, NOT runtime base). Missing/not found → show list + "Session not found", stop.
	2. Look up ID in index (`.qwen/chat-index.json` in project root, NOT runtime base). **JSON parse error → output `"chat-index.json is malformed. Fix it manually before resuming."` and stop. Do NOT proceed.** Missing/not found → show list + "Session not found", stop.

[wenshao]

[Suggestion] This PR adds a second # Qwen Code Configs block (line 65) that duplicates the existing one at line 30. Both define .qwen/* with negations. The second block adds only !.qwen/chat-src/ and !.qwen/chat-src/**.

Duplicate gitignore blocks are a maintenance hazard: if someone adds an exception to the first block only, the second block's .qwen/* silently overrides it. Also, logs/ is placed directly under this heading, making it appear as a Qwen Code config entry.

Suggested change

	# Qwen Code Configs
	# (Merge into the existing "Qwen Code Configs" block at line 30 — add the two chat-src negations there and remove this duplicate block)

[wenshao]

[Suggestion] "Write back" without atomic write protection. An interrupted write (OOM, Ctrl+C, timeout) truncates chat-index.json. All four sub-commands then report "malformed" with no self-repair mechanism.

The design doc (section 1.3) identifies this as a lesson from review round 2 ("saveSessionToIndex 没有原子写入"), yet the current instructions don't implement it. The same issue exists in chat-delete.md step 5.

Suggested change

	6. Add or update `{{name}}` key in existing index object. Write back (2-space indent, ensure `.qwen/` exists).
	6. Add or update `{{name}}` key in existing index object. **Write atomically**: write to `.qwen/.chat-index.json.tmp` first, then rename/move to `.qwen/chat-index.json`. Do NOT write directly to the index file.

[wenshao]

[Suggestion] The runtimeBase resolution docs list 2 tiers ($QWEN_RUNTIME_DIR > ~/.qwen). The actual Storage.getRuntimeBaseDir() has 4 tiers including settings.json's advanced.runtimeOutputDir and AsyncLocalStorage context. Users with runtimeOutputDir configured will see /chat -l return "No saved sessions" even though sessions exist — a silent failure with no error message.

The "Note" about this is accurate but buried. Consider elevating it: add a detection step that warns when ~/.qwen/projects/<sanitizeCwd>/chats/ is empty but sessions are expected.

— glm-5.1 via Qwen Code /review

[wenshao]

[Suggestion] FileCommandLoader scans **/*.md recursively, so /chat-save, /chat-list, /chat-resume, /chat-delete all appear as independent slash commands. Direct invocation (e.g., /chat-save my-session) bypasses the router's argument parsing, locale detection, and name validation.

Options: (a) move sub-commands to a non-scanned location (e.g., .qwen/chat-includes/), (b) prefix with _ and update the loader to skip them, or (c) accept the dual-path and add a note to each sub-command that direct invocation skips validation.

@lnxsun 首先感谢你在 #3105 之后又这么有耐心地把它重塑成 file-based custom commands 的形态，包括跨平台命令、测试套件、以及和 @wenshao 来回这么多轮的细节打磨

不过想在继续往下推之前，先和你对一下底层需求：

主仓目前已经有一套内建的 session 管理命令（#3093 落地的）：

• /rename / /rename --auto（别名 /tag）—— 给当前会话起名
• /resume（无参出 picker） / /resume （按 title 模糊匹配） / /resume / CLI --resume <title>
• /delete —— 删除会话

从命令表面看，/chat -s/-l/-r/-d 想覆盖的场景这边基本都能做到。所以想请你帮我们澄清一下：

1. 你日常用 /chat -s/-l/-r/-d 时，有没有哪个具体场景是上面这套内建命令做不到、或者用起来不顺的？比如多个名字指向同一个 session、在新终端窗口里 resume、跨项目找历史会话之类的？
2. 如果有，我们更倾向于把这个缺口补在内建命令里（SessionService 层），而不是再维护一套并行的实现 —— 这样所有用户都受益，也不用关心 .qwen/commands/ 是否被覆盖、是否同步。

如果你能给一两个具体的"我现在用 /rename + /resume 解决不了的场景"，我们一起看看是补在哪里最合适。再次感谢！

感谢 @wenshao 的详细 review！已针对所有 Critical 和 Suggestion 问题完成整改：

Critical 问题修复

1. Step 6 Shell Safety (命令注入防护)

• 原问题: 黑名单方式遗漏了单引号、双引号、反斜杠、换行符等危险字符
• 修复: 改用白名单 ^[a-zA-Z0-9/._-]+$，Windows 额外拒绝 ^、%、\
• 说明: 白名单方式从根本上防止 command injection

2. macOS sed 转义修复

• 原问题: sed "s/'/\\\\'/g" 在单引号字符串中无效
• 修复: 改为 sed "s/'/'\\\\''/g" (正确的 bash 单引号内嵌入单引号语法)

3. WSL wt.exe 多余引号

• 修复: 删除行尾多余的 "

4. 删除 spaces 从 blocklist

• 说明: 所有平台的命令模板都已正确引用路径，空格是正常路径字符

Suggestion 问题修复

5. chat-resume.md: 添加 index malformed 处理

6. chat-resume.md: 修正 limitation note (删除 SHA-256 错误描述)

7. chat-save.md: 添加 .jsonl corrupt 处理

8. chat-save.md: 原子写入 (写 .tmp 再 rename)

9. chat-save.md: 删除重复的 Runtime Base block

10. test.mjs [8.5]: 加强断言

11. .gitignore: 合并重复 block

12. 子命令文件添加 Note (直接调用会绕过路由器验证)

Qwen Code resolved the merge conflicts and pushed the branch update.

Merge Conflict Resolution Summary — PR #3190

Base branch

origin/main

Conflicted file

.gitignore (only file with conflicts)

Conflict 1 — .qwen/ un-ignore exceptions (lines 48–60)

HEAD (PR branch) added:

!.qwen/chat-src/
!.qwen/chat-src/**

These un-ignore the chat-src directory, part of PR #3190's chat file commands feature.

origin/main added:

!.qwen/team-memory/
!.qwen/team-memory/**
.qwen-session

These un-ignore team-memory (a separate feature) and ignore the developer-local session identifier.

Resolution: Kept both sides. They are independent, non-overlapping additions for different features.

Conflict 2 — entries after packages/vscode-ide-companion/*.vsix

HEAD (PR branch) added:

# Qwen Code Configs

A stray duplicate comment — # Qwen Code Configs already exists earlier in the file.

origin/main added:

logs/
.repro-runs/

logs/ was a duplicate (already listed under # Log files earlier in the file, from the PR branch's reorganization). .repro-runs/ was a genuinely new ignore entry.

Resolution: Kept .repro-runs/ from main. Dropped the duplicate logs/ from main (already present higher in the file). Dropped the stray # Qwen Code Configs comment from HEAD (redundant).

Net changes in .gitignore vs origin/main

• Added !.qwen/chat-src/ and !.qwen/chat-src/** (PR feature)
• Added # Log files section with logs/ at a better-organized position (from PR branch, replacing the loose logs/ that main had at the bottom)
• Removed loose logs/ from near the bottom (was duplicate after reorganization)
• Kept .repro-runs/ (from main)
• Kept team-memory exceptions and .qwen-session (from main, auto-merged without conflict)

Commit

fix: resolve merge conflict in .gitignore with origin/main

Review Summary

This PR adds file-based /chat slash commands for session management (save, list, resume, delete). The architecture is sound — splitting into 5 files with a router pattern is clean, the security considerations (prototype pollution, shell injection, shared references) are well-thought-out, and the 248-assertion test suite is impressive for a file-command PR.

However, there are several issues that need addressing before merge:

Critical:

1. Windows path validation blocks all native Windows resume — the whitelist regex ^[a-zA-Z0-9/._-]+$ rejects \ and :, making resume impossible for every Windows drive-letter path.
2. Test suite has 2 failing assertions on checked-in code — token budget exceeded (14,657 > 14,000) and missing "2-space indent" assertion.
3. Production file incorrectly claims SessionService uses sanitizeCwd — it actually uses getProjectHash() (SHA-256).
4. chat-delete.md missing atomic write — chat-save has it, delete doesn't, same index file.
5. Save/resume asymmetry — save allows sessions with no cwd field, resume rejects them.
6. chat-save saves corrupt sessions without warning they're unresumable.

Suggestions: No CI integration for tests, production files 82% larger than design doc claims, design doc has duplicate section numbers and stale content, macOS/Linux terminals close after qwen exits while Windows doesn't.

[qwen-code-ci-bot]

[Critical] Windows path validation blocks all native Windows resume

The whitelist regex ^[a-zA-Z0-9/._-]+$ rejects both \ and :, which are present in every Windows drive-letter path (e.g., D:\code\project). Since <projectRoot> is sourced from the JSONL cwd field (step 4, line 13), it will always contain these characters on native Windows. Resume will always abort with "Error: Session path contains unsafe characters" for all Windows users.

Fix: Use platform-aware validation. On Windows, allow \ and : (e.g., ^[a-zA-Z0-9/._:\\-]+$), while still rejecting $, backtick, ;, |, >, <, &, (, ), ', ", newlines.

— qwen3.7-max via Qwen Code /review

[qwen-code-ci-bot]

[Critical] Test suite has 2 failing assertions on checked-in code

Running node .qwen/chat-src/scripts/test.mjs reports: Passed: 246, Failed: 2, Total: 248.

Failures:

1. Total < 14000 chars — actual: 14,657 chars (line 79)
2. chat-save prod specifies 2-space indent for JSON output — production file has no mention of "indent"

The committed test-output.txt (showing 241 passing, 0 failing) is stale and does not match the current state. The safety net is broken.

Fix: Either raise the soft budget to 15,000 or trim production files; add "2-space indent" to production chat-save.md step 6 or remove the assertion.

— qwen3.7-max via Qwen Code /review

[qwen-code-ci-bot]

[Critical] Incorrect SessionService claim misleads the AI at runtime

This states: "Both these commands and the core SessionService use sanitizeCwd for session directory resolution." This is factually wrong — sessionService.ts uses getProjectHash() which is SHA-256 based. The source version of this file correctly states the mismatch.

The production file is what the LLM actually executes. By claiming both layers use the same algorithm, you're actively misleading the AI into believing there is no mismatch — when in reality the hash collision profiles are completely different between SHA-256 and sanitizeCwd.

Fix: Replace with: "The core SessionService uses getProjectHash() (SHA-256) for ownership checks, while file commands use sanitizeCwd(). This is a known mismatch — the collision profiles differ (SHA-256 is effectively collision-free; sanitizeCwd has documented collisions like /home/a-b/c vs /home/a/b-c)."

— qwen3.7-max via Qwen Code /review

[qwen-code-ci-bot]

[Critical] Missing atomic write — save has it, delete doesn't

Step 5 says "Remove {{name}} from index, write back" with no atomic-write instruction. Compare with chat-save.md step 6 which explicitly requires: "Write atomically: write to .qwen/.chat-index.json.tmp first, then rename/move to .qwen/chat-index.json."

Both operations modify the same chat-index.json file. An interrupted delete (kill -9, crash, power loss) corrupts the index. All four sub-commands then report "chat-index.json is malformed. Fix it manually." with no self-repair path.

Fix: Mirror chat-save.md step 6: "Write atomically: write to .qwen/.chat-index.json.tmp first, then rename/move to .qwen/chat-index.json. Do NOT write directly to the index file."

— qwen3.7-max via Qwen Code /review

[qwen-code-ci-bot]

[Critical] Save/resume asymmetry: save allows sessions that resume will always reject

chat-save step 5 allows saving sessions with no cwd field ("skip verification, legacy session"). But chat-resume step 4 (line 12) aborts on the same condition: "Session record missing project context. Aborted."

Users get a successful save confirmation (Saved: name → <id>) for a session that can never be resumed. This is a silent data integrity issue — the user believes the session is saved and recoverable, but it's actually a dead entry.

Fix: Make verification symmetric — either both allow with warning, or both abort. Recommended: chat-save should warn "Warning: session has no cwd field — this session will NOT be resumable. Save anyway? (yes/no)" before proceeding.

— qwen3.7-max via Qwen Code /review

[qwen-code-ci-bot]

[Suggestion] Production files 82% larger than claimed — 75% token savings is incorrect

Section 2.1 claims: "子命令各 ~0.5KB（~150 token）" and "执行 /chat -l 只加载 chat.md + chat-list.md = ~500 token，比原始方案节省 75%."

Actual production total: 14,657 chars (per the test suite's own measurement). The per-file estimates here are significantly understated. The 75% savings claim is internally inconsistent with the actual file sizes.

Fix: Update the token estimates to match reality, or remove the specific percentage claim and replace with a qualitative statement like "splitting reduces per-invocation token load."

— qwen3.7-max via Qwen Code /review

[qwen-code-ci-bot]

[Suggestion] Design doc claims confirmation is "Step 0" but actual file has Step 4

Section 3.4 states: "chat-delete.md 将确认步骤设为 Step 0（在验证名称之前）."

But the actual chat-delete.md has confirmation at Step 4 (after validate, read index, not-found check). The design doc and the implementation disagree.

Also: the design doc has duplicate section numbers — there are two section 7s (7.1/7.2 and 7.1/7.2 again) and two section 8s. This makes cross-referencing unreliable.

Fix: Update section 3.4 to say "Step 4" instead of "Step 0", or renumber the actual file to make confirmation Step 0. Also fix the duplicate section numbering.

— qwen3.7-max via Qwen Code /review

[qwen-code-ci-bot]

[Suggestion] Section 4.2 resume table omits cd and entire WSL pathway

The table shows commands like qwen --resume <id> without cd '<projectRoot>'. In practice, qwen would start in the user's home directory, not the project directory — the session would fail to find project-specific context.

Additionally, the table entirely omits the WSL pathway (Linux platform + /proc/version contains "Microsoft" → use wslpath conversion + cmd.exe/wt.exe). The production files implement this at chat-resume.md lines 26-28.

Fix: Update the table to include cd '<projectRoot>' in all commands, and add a WSL row showing the wslpath conversion flow.

— qwen3.7-max via Qwen Code /review

[qwen-code-ci-bot]

[Suggestion] macOS/Linux terminals close after qwen exits; Windows doesn't

Windows uses -NoExit (PowerShell) and /k (CMD) to keep the terminal window open after qwen exits. But macOS osascript (line 25) and Linux bash -c (line 29) close the terminal when qwen exits.

This means:

• Windows user: sees the output, can read it at leisure
• macOS/Linux user: terminal window opens, qwen runs, terminal closes — output may flash and disappear

Fix: For macOS, add && read -p 'Press Enter to close...' after the qwen command in the osascript script. For Linux, use bash -c "... && read -p 'Press Enter to close...'" or switch to --hold flags where available (gnome-terminal supports --hold).

[qwen-code-ci-bot]

[Suggestion] Duplicate "### 6." step numbering

Both "### 6. Write to Index" (line 61) and "### 6. Confirm" (line 68) use the same step number. The production file correctly uses 6 and 7.

This source-of-truth document should match the production numbering to avoid confusion when developers cross-reference.

Fix: Renumber "### 6. Confirm" to "### 7. Confirm".

[qwen-code-ci-bot]

Hi @lnxsun, thanks for the detailed PR! The design doc and test suite show real effort.

Before diving into code review, I need to flag a template issue — the PR body is missing several required sections from the PR template:

• "Why it's needed" — The Background section explains the history (PR #3105 closed, PR #1113 deprecated /chat), but doesn't make the case for why this feature is needed now. What user problem does named session management solve that --continue/--resume CLI flags don't already cover?
• "Reviewer Test Plan" — No steps for a reviewer to verify the commands work. Custom commands are markdown instruction files, so tmux testing isn't straightforward, but the template still asks for verification steps.
• "Risk & Scope" — What are the tradeoffs? E.g., these commands read runtime internals (session file layout, sanitizeCwd) directly — if the core session storage format changes, these break silently.
• "Tested on" — The OS matrix is empty.

Please update the PR body to match the template and re-request review. A few other things to consider while you're at it:

1. The .gitignore change (moving logs/) looks unrelated — could you split that into a separate commit or PR?
2. The scope is large (15 files, 1685 lines) for what are essentially 5 markdown command files (~219 production lines). The source/production dual version (chat-src/), archived build script, 372-line test script, and test output artifacts feel like development scaffolding that might not belong in the repo. Have you considered committing just the production files?
3. PR #1113 intentionally deprecated built-in /chat commands. This PR re-introduces equivalent functionality through the custom commands mechanism. Is the intent to show that custom commands can replicate built-in features, or is there a genuine user need for named session management beyond what --continue/--resume provides?

中文说明

@lnxsun 你好，感谢这个详细的 PR！设计文档和测试套件可以看出投入了不少精力。

在进入代码审查之前，需要指出 PR 正文缺少PR 模板中的几个必填部分：

• "Why it's needed" — Background 部分解释了历史（PR #3105 被关闭，PR #1113 废弃了 /chat），但没有说明为什么现在需要这个功能。命名会话管理解决了什么用户问题，是 --continue/--resume CLI 参数无法覆盖的？
• "Reviewer Test Plan" — 没有给审查者的验证步骤。自定义命令是 markdown 指令文件，tmux 测试不太直观，但模板仍然要求验证步骤。
• "Risk & Scope" — 有哪些权衡？例如，这些命令直接读取运行时内部结构（会话文件布局、sanitizeCwd）——如果核心会话存储格式变更，这些命令会悄悄失效。
• "Tested on" — 操作系统矩阵为空。

请按照模板更新 PR 正文后重新提交审查。同时请考虑以下几点：

1. .gitignore 的改动（移动 logs/）看起来与本 PR 无关——能否拆成单独的 commit 或 PR？
2. 对于本质上是 5 个 markdown 命令文件（约 219 行生产代码）的内容，范围较大（15 个文件，1685 行）。源/生产双版本（chat-src/）、归档的构建脚本、372 行的测试脚本和测试输出产物看起来像是开发脚手架，可能不应该提交到仓库中。是否考虑过只提交生产文件？
3. PR #1113 有意废弃了内置的 /chat 命令。本 PR 通过自定义命令机制重新引入了等价功能。目的是展示自定义命令可以复现内置功能，还是确实存在超出 --continue/--resume 能力的命名会话管理需求？

Hi @lnxsun, thanks for the PR and the persistence through many review rounds!

Template: The PR body uses custom headings (Summary, Background, Design, Testing, Files Changed) instead of the repo's template. Missing: "What this PR does", "Why it's needed", "Reviewer Test Plan" (how a reviewer verifies this works, with Tested on table), "Risk & Scope", and "Linked Issues". Could you reformat the PR body to follow the template? This is important for reviewers who need a test plan.

Problem & Direction: This is the more important question. The repo already ships built-in session management commands via PR #3093: /rename, /resume (with picker and title matching), /delete, and --resume <title> CLI flag. Both @qqqys and @yiliang114 have asked for concrete scenarios where the built-in commands fall short — and that question is still unanswered.

PR #3105 was closed specifically because maintainers "don't want to keep two sets of interactions for the same behavior." The file-based .qwen/commands/ approach avoids touching core code, which is clever, but shipping these files in the repo's default .qwen/commands/ directory gives every user a parallel session management interface — the same outcome #3105 was closed for.

@yiliang114's suggestion is worth considering: keep this as an example/recipe/plugin users can opt into, rather than something shipped by default. That preserves the creative use of custom commands without duplicating the built-in interaction model.

Size: No core paths touched — all changes are in .qwen/commands/ and .qwen/chat-src/. Not applicable for core module protection.

Approach: The 5 production command files are clean and minimal (~219 lines). The supporting .qwen/chat-src/ directory (design doc, source versions with comments, 372-line test suite, archived build script) adds ~1,400 lines. If this moves forward, consider whether the source/production dual version and the archived build script are needed, or if the production commands + design doc alone suffice.

Flagging the product direction question for @tanzhenxin @wenshao @qqqys before diving deeper into code review.

中文说明

感谢 @lnxsun 的持续投入！

模板: PR 正文使用了自定义标题，缺少仓库模板要求的 "What this PR does"、"Why it's needed"、"Reviewer Test Plan"（含 Tested on 表格）、"Risk & Scope"、"Linked Issues" 章节。请按模板重新组织。

问题与方向: 这是更关键的问题。仓库已通过 PR #3093 内置了会话管理命令：/rename、/resume（含 picker 和标题匹配）、/delete、--resume <title> CLI 参数。@qqqys 和 @yiliang114 都要求提供内置命令无法满足的具体场景——这个问题目前仍未回答。

PR #3105 被关闭的原因是维护者"不想为同一行为维护两套交互"。file-based .qwen/commands/ 方案避免了修改核心代码，但在仓库默认的 .qwen/commands/ 目录中发布这些文件，会给每个用户一套并行的会话管理界面——和 #3105 被关闭的原因相同。

@yiliang114 的建议值得考虑：将其作为用户可选的示例/配方/插件，而非默认发布。这样既保留了自定义命令的创意用法，又不会重复内置交互模型。

规模: 未触及核心路径，不适用核心模块保护。

方案: 5 个生产命令文件简洁清晰（约 219 行）。配套的 .qwen/chat-src/ 目录增加了约 1,400 行。如果继续推进，请考虑是否需要源文件/生产文件双版本和归档的构建脚本，还是仅生产命令 + 设计文档就够了。

标记产品方向问题，等待 @tanzhenxin @wenshao @qqqys 确认后再深入代码审查。

Code Review

The 5 production command files are well-structured. Security practices are solid — name validation with whitelist regex, prototype pollution blocking, shell metacharacter rejection, atomic writes, confirmation prompts for destructive operations. The cross-platform terminal launch commands (Windows/macOS/Linux/WSL) are thorough.

Two issues worth noting:

Test suite has 2 failures on HEAD. Running node .qwen/chat-src/scripts/test.mjs reports 246/248 passing:

• Total < 14000 chars — production files total 14,657 bytes, exceeding the 14,000 char budget the test itself sets. The PR body claims ~2,640 chars (~924 tokens), but the actual total is over 5x that. The token efficiency claim in the PR description is significantly outdated.
• chat-save prod specifies 2-space indent for JSON output — the production chat-save.md doesn't mention 2-space indent, but the source version does and the test expects consistency.

The first failure suggests the production files have grown substantially through review iterations (security rules, error handling specs, edge case documentation) while the budget hasn't kept pace. Not a blocker, but the PR description should be updated to match reality.

Scope creep in supporting files. The .qwen/chat-src/ directory adds ~1,400 lines: source versions of each command with detailed WHY comments (5 files), a 351-line design doc, a 372-line test suite, an archived build script, and a test output log. The design doc is genuinely useful. But the source/production dual version doubles maintenance burden, and the archived build script (_archived/build.mjs) and test output (test-output.txt) shouldn't be committed to the repo. If the dual version is kept, there should be a CI check ensuring source and production stay in sync — right now that's just the test.mjs script run manually.

Testing

These are custom slash commands (AI-interpreted prompts loaded from .qwen/commands/), not compiled CLI features. They require the Qwen Code CLI running interactively with the PR branch checked out. The dev build environment (tsx) isn't available in this CI runner, so full E2E testing wasn't possible here.

Verified from the PR branch checkout:

• All 5 production command files exist and are well-formed
• Test suite runs: 246/248 passing (2 failures noted above)
• File sizes: chat.md 6,269B, chat-resume.md 4,104B, chat-save.md 1,904B, chat-delete.md 1,633B, chat-list.md 747B — total 14,657B

代码审查

5 个生产命令文件结构良好。安全实践可靠——名称白名单验证、原型污染拦截、shell 元字符拒绝、原子写入、破坏性操作确认提示。跨平台终端启动命令（Windows/macOS/Linux/WSL）处理完善。

两个值得注意的问题：

测试套件在 HEAD 上有 2 个失败。 运行 node .qwen/chat-src/scripts/test.mjs 报告 246/248 通过：

• Total < 14000 chars — 生产文件总计 14,657 字节，超出了测试自身设定的 14,000 字符预算。PR 正文声称约 2,640 字符（约 924 token），但实际总量超过 5 倍。PR 描述中的 token 效率声明严重过时。
• chat-save prod specifies 2-space indent for JSON output — 生产版 chat-save.md 未提及 2 空格缩进，但测试期望一致性。

配套文件的范围蔓延。 .qwen/chat-src/ 目录增加了约 1,400 行。设计文档确实有用，但源文件/生产文件双版本使维护负担翻倍，归档的构建脚本和测试输出不应提交到仓库。

测试

这些是自定义斜杠命令（AI 解释的提示），需要 Qwen Code CLI 交互模式运行。CI 环境中无法进行完整 E2E 测试。

从 PR 分支检出验证：所有 5 个生产命令文件存在且格式良好；测试套件 246/248 通过。

The code quality is genuinely good — the production command files are clean, security-conscious, and well-documented. The author clearly put significant effort into this. But stepping back, this PR has a fundamental problem that no amount of polish resolves: it ships a parallel session management interface by default, which is exactly what #3105 was closed for.

The built-in /rename, /resume, /delete commands (from #3093) already cover named session management. Two maintainers (@qqqys, @yiliang114) asked the author to provide concrete scenarios where these built-in commands fall short. That question was never answered — the author's responses focused on implementation details rather than the product gap.

The file-based .qwen/commands/ approach is a creative workaround for "no core code changes." But shipping these files in the repo's default .qwen/commands/ means every user gets both interfaces, and the project maintains both. If the goal is to demonstrate custom command capabilities, @yiliang114's suggestion to ship this as an opt-in example/recipe rather than a default makes more sense.

Other concerns:

• The PR body doesn't follow the repo's template — missing "Reviewer Test Plan", "Risk & Scope", "Linked Issues" sections.
• The PR's own test suite has 2 failures on HEAD (token budget exceeded, source/production inconsistency).
• The token efficiency claim in the PR description (~2,640 chars) is significantly outdated — actual total is 14,657 bytes.
• The .qwen/chat-src/ directory (archived build script, test output log, dual source/production versions) adds maintenance burden that doesn't belong in the default repo.

This needs a product direction decision from the maintainer team before it can merge. If the direction is approved, the scope should be trimmed (drop chat-src or make it opt-in, fix test failures, update PR description).

中文说明

代码质量确实很好——生产命令文件简洁、安全意识强、文档完善。但退一步看，这个 PR 有一个根本性的问题：它默认发布了一套并行的会话管理界面，这正是 #3105 被关闭的原因。

内置的 /rename、/resume、/delete 命令（来自 #3093）已经覆盖了命名会话管理。两位维护者（@qqqys、@yiliang114）要求作者提供内置命令无法满足的具体场景，但这个问题从未被回答。

基于文件的 .qwen/commands/ 方案是一个有创意的变通方案。但在仓库默认的 .qwen/commands/ 目录中发布这些文件，意味着每个用户都会获得两套界面，项目也需要维护两套。如果目标是展示自定义命令能力，@yiliang114 建议的"可选示例/配方"方式更合理。

其他问题：PR 正文不符合模板；测试套件有 2 个失败；token 效率声明严重过时（声称 2,640 字符，实际 14,657 字节）；.qwen/chat-src/ 目录增加了不必要的维护负担。

需要维护团队先做产品方向决策，才能合并。

PR #3190 Review 回复

感谢 review！已根据反馈修复了代码层面的所有问题。产品方向问题（1、2）待 maintainer 团队决策，以下为其他问题的处理情况：

已修复

3. 测试失败

• [4] Token budget — 14,519 chars → 13,817 chars（< 14,000 上限）。删除了 chat-resume.md 中的 limitation note、whitelist 解释行、chat.md 中的 runtimeOutputDir 注记，token 预算已实测通过。
• [11] chat-save prod 缺少 2-space indent — Step 6 已补充 (2-space indent)\，与 source 文件保持一致。

4. .qwen/chat-src/\ 目录

• 已从 git 追踪中移除（\git rm --cached\ + .gitignore\ 中去掉 un-ignore 规则）。
• 目录保留在本地磁盘，开发者可自行 opt-in 使用，不再随默认仓库发布。
• 包括：CHAT-DESIGN.md、source 文件副本、test.mjs、已归档的 build.mjs、test-output.txt。

6. Token 数据过时

• CHAT-DESIGN.md 已更新为实际数据：13,817 chars / ~4,836 tokens（原 8,028 / ~2,810）。差距主要是后期新增了 WSL 检测、cwd 项目验证、Shell 安全引用、CMD 回退等安全特性所致。

待处理（需 PR 作者手动操作）

5. PR 描述模板

• PR body 缺少 \Reviewer Test Plan\、\Risk & Scope\、\Linked Issues\ 章节。PR 中的 Token 数据（~2,640 chars）也已过时，建议更新为实际 13,817 chars。

未处理（待 maintainer 决策）

1. 产品方向冲突 — 这套 .qwen/commands/chat-*\ 与 PR #3093 内置的 /rename//resume//delete\ 功能重叠。之前 #3105 因此关闭。需要说明内置命令无法满足的具体场景。

2. 默认启用 vs 可选示例 — @yiliang114 建议改为 opt-in 的 example/recipe。如方向获批，可进一步 slim scope。
