feat(#2505): Phase 0 — Kimi PreToolUse guard vocabulary normalization (precondition; carries PR #2326 forward) (#2518)
* fix(#2304): normalize Kimi tool vocabulary in PreToolUse guard payload checks
The Kimi [[hooks]] registrations translate the matcher to Kimi's tool
vocabulary (WriteFile|StrReplaceFile) but the guard scripts early-exit
unless the payload's tool_name is a Claude name (Write/Edit/MultiEdit),
so every guard was dormant on Kimi: the matcher fired, the script saw
WriteFile, and exit(0)'d.
Normalize the payload's tool_name at the top of each guard
(WriteFile -> Write, StrReplaceFile -> Edit; bare or module-qualified
kimi_cli.tools.file:* forms) before the check. Inlined per guard rather
than a hooks/lib/ helper because hook scripts are staged as standalone
files on every hook surface, and a sibling require is a staging
dependency that can fail silently.
Regression tests pipe Kimi-vocabulary payloads at each guard and assert
it engages (typed fields: exit status, decision, hookSpecificOutput) —
verified red against the pre-fix scripts, green after.
* fix(#2304): normalize Kimi tool_input fields and route block reasons to stderr
Cross-AI review of the initial fix, verified against kimi-cli source,
found the tool_name normalization alone leaves the guards dormant on a
real Kimi runtime: kimi-cli forwards tool_input verbatim
(src/kimi_cli/hooks/events.py), and its tool schemas
(src/kimi_cli/tools/file/{write,replace}.py) use path/content and
edit.old/edit.new (single Edit or list) — not Claude's
file_path/old_string/new_string. The guards read file_path, got '',
and exited 0 past the now-open tool_name gate.
Extend the per-guard normalization to the payload fields
(path -> file_path, edit -> old_string/new_string with list flattening),
and write the worktree guard's block reason to stderr as well as the
stdout JSON — Kimi feeds stderr, not stdout, back to the model on
exit 2 (docs/en/customization/hooks.md exit-code table).
Regression tests rewritten to Kimi's actual payload shapes (plus an
edit-list case and a stderr-reason assertion) — verified red against
the name-only fix, green after.
* fix(#2304): join all edit[] entries into old_string, matching new_string
Review nit on #2326: old_string took only edits[0].old while new_string
joined the whole list. Symmetric join removes the latent trap for any
future consumer sizing before/after content (e.g. the #2255 write guard).
* fix(#2304): normalize Kimi ReadFile vocabulary in read-injection scanner
Review Major 2 on #2326: gsd-read-injection-scanner.js had the identical
dormancy — its Kimi matcher fires on 'ReadFile' but the SCANNED_TOOLS
check only knew 'Read', so injected content in read files was never
flagged on Kimi installs.
Folds the same inlined normalization block into the scanner and extends
the shared KIMI_TOOL_NAMES map with ReadFile:'Read' in all four copies so
they stay byte-identical. Harmless in the three write guards: a
normalized 'Read' falls out of their Write/Edit allowlist exactly as the
unmapped name did. Field mapping verified against kimi-cli upstream
(src/kimi_cli/tools/file/read.py Params.path); the existing
path->file_path copy covers the scanner's file_path read.
* test(#2304): parity test binding the four inlined Kimi normalization copies
Review Major 1 on #2326: KIMI_TOOL_NAMES + normalizeKimiPayload is
deliberately inlined in four hook scripts (staging-dependency rationale,
unchanged), with the inverse table in bin/install.js — five
hand-maintained surfaces and nothing binding them.
Static binding, zero runtime coupling:
- the four inlined blocks must be byte-identical;
- each guard-map entry must be the value-inverse of
convertKimiToolName() for its Claude name;
- every guard-relevant Claude tool (Write/Edit/MultiEdit/Read) must have
a reverse entry — a vocabulary rename or extension that updates the
installer without updating the guards now fails in CI instead of
leaving a guard silently dormant (the #2304 recurrence door).
Negative-controlled: diverging one copy or dropping a map entry fails
the suite against the fixed code.
* test(#2304): regenerate golden parity fixtures for guard hook changes
CI red on #2326: all 10 golden-parity failures were the staged guard
hooks drifting from their fixtures. Regenerated with npm run gen:golden
(after npm run build) under throwaway HOME/CLAUDE_CONFIG_DIR; diff
verified to change exactly the four PR-touched guard entries per
surface, nothing else.
* test(#2304): regression tests for Kimi ReadFile engaging the scanner
Mirrors the per-guard Kimi vocabulary tests the PR added for the three
write guards: bare and module-qualified ReadFile produce the advisory,
path exclusions still apply post-normalization, unknown Kimi names stay
fail-open. Negative-controlled against the pre-fold scanner (the two
positive cases fail there; exclusion/fall-through correctly pass on
both sides).
* fix(#2304): normalize Kimi Shell vocabulary in workflow guard
Withdraws the disclosed out-of-scope split: verification showed the
Bash->Shell case needs NO different mapping — kimi-cli's Shell.Params
names its field `command` (src/kimi_cli/tools/shell/__init__.py), same
as Claude's Bash — and the guard's write branch (Write/Edit/MultiEdit
allowlist) was ALSO dormant on Kimi under its Shell|WriteFile|
StrReplaceFile matcher. Same defect class as the other four hooks.
Folds the identical inlined block into gsd-workflow-guard.js and
extends the shared map with Shell:'Bash' in all five copies (harmless
outside the workflow guard: a normalized Bash falls out of the other
guards' checks as before). Parity test now binds five copies and adds
Bash to the dormancy alarm. New workflow-guard test file exercises the
observable block (force-add on a worktree-agent branch): Shell bare and
module-qualified block with WORKTREE_AGENT_FORCE_ADD_FORBIDDEN, benign
Shell passes, Claude Bash unchanged — negative-controlled against the
pre-fold guard (the two Kimi cases fail there). Golden parity fixtures
regenerated; diff verified to change exactly the five guard entries per
surface.
* fix(#2304): map Kimi tool_output and route workflow-guard block to stderr
Third-party review (cross-AI verifier) caught two gaps in the revision:
1. Kimi PostToolUse events carry `tool_output`, not `tool_response`
(kimi-cli src/kimi_cli/hooks/events.py post_tool_use()), so the
read-injection scanner — which reads data.tool_response — was STILL
dormant on real Kimi payloads; the earlier tests passed because they
sent Claude-shaped payloads. The shared normalization block now maps
tool_output -> tool_response (inert in PreToolUse guards, where the
field is absent), and the scanner's Kimi tests send the real shape.
2. The workflow guard's force-add block wrote its reason to stdout only.
Kimi's exit-2 protocol feeds stderr back to the model — the exact
fix this PR already applied to the other blocking guard — so the
newly-awakened block would have been a silent denial. Reason now
also routed to stderr, asserted in the test.
Also: the scanner's "unknown name" test now uses a genuinely unmapped
name (FetchURL) — Shell stopped qualifying when it entered the map —
and the workflow guard's write branch (WriteFile advisory,
StrReplaceFile .planning pass) gains behavioral coverage. All five
copies stay byte-identical (parity test green); golden fixtures
regenerated, diff verified to the five guard entries per surface.
Negative-controlled: 3 new assertions fail against the pre-fix hooks.
* docs(#2304): update changeset to cover the full five-guard fix
Review round 2 (2026-07-18) flagged the changeset as stale: it was
written for the first commit and still described only the three guards
named in the issue. The shipped diff grew to five guards plus two
payload dimensions the original body never mentioned. The body now
names gsd-read-injection-scanner and gsd-workflow-guard, the ReadFile
and Shell vocabulary entries, the tool_output -> tool_response mapping,
and the workflow guard's stderr block-reason routing.
* test(#2304): regenerate kilo golden fixture after #2305 landed on next
The branch's fixture sweep predates

fix(hooks): detect Claude Code via stdin session_id (closes #2520) (#2521)
* fix(hooks): detect Claude Code via stdin session_id, not filtered env (#2520) The #2344 fix assumed `CLAUDECODE` would propagate to hook subprocesses. On Claude Code v2.1.116 it doesn't — Claude Code applies a separate env filter to PreToolUse hook commands that drops bare CLAUDECODE and CLAUDE_SESSION_ID, keeping only CLAUDE_CODE_*-prefixed vars plus CLAUDE_PROJECT_DIR. As a result every Edit/Write on an existing file produced a redundant READ-BEFORE-EDIT advisory inside Claude Code. Use `data.session_id` from the hook's stdin JSON as the primary Claude Code signal (it's part of Claude Code's documented PreToolUse hook-input schema). Keep CLAUDE_CODE_ENTRYPOINT / CLAUDE_CODE_SSE_PORT env checks as propagation-verified fallbacks, and keep the legacy CLAUDE_SESSION_ID / CLAUDECODE checks for back-compat and future-proofing. Add tests/bug-2520-read-guard-hook-subprocess-env.test.cjs, which spawns the hook with an env mirroring the actual Claude Code hook-subprocess filter. Extend the legacy test harnesses to also strip the propagation-verified CLAUDE_CODE_* vars so positive-path tests keep passing when the suite itself runs inside a Claude Code session (same class of leak as #2370 / PR #2375, now covering the new detection signals). Non-Claude-host behavior (OpenCode / MiniMax) is unchanged: with no `session_id` on stdin and no CLAUDE_CODE_* env var, the advisory still fires. Closes #2520 * test(2520): isolate session_id signal from env fallbacks in regression test Per reviewer feedback (Copilot + CodeRabbit on #2521): the session_id isolation test used the helper's default CLAUDE_CODE_ENTRYPOINT / CLAUDE_CODE_SSE_PORT values, so the env fallback would rescue the skip even if the primary `data.session_id` check regressed. Pass an explicit env override that clears those fallbacks, so only the stdin `session_id` signal can trigger the skip. Other cases (env-only fallback, negative / non-Claude host) already override env appropriately. --------- Co-authored-by: forfrossen <forfrossensvart@gmail.com> |

fix(hooks): skip read-guard advisory on Claude Code runtime (#2001)
* fix(hooks): skip read-guard advisory on Claude Code runtime (#1984) Claude Code natively enforces read-before-edit at the runtime level, so the gsd-read-guard.js advisory is redundant — it wastes ~80 tokens per Write/Edit call and clutters tool flow with system-reminder noise. Add early exit when CLAUDE_SESSION_ID is set (standard Claude Code session env var). Non-Claude runtimes (OpenCode, Gemini, etc.) that lack native read-before-edit enforcement continue to receive the advisory as before. Closes #1984 Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * fix(hooks): sanitize runHook env to prevent test failures in Claude Code The runHook() test helper now blanks CLAUDE_SESSION_ID so positive-path tests pass even when the test suite runs inside a Claude Code session. The new skip test passes the env var explicitly via envOverrides. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> --------- Co-authored-by: Claude Opus 4.6 <noreply@anthropic.com> |

fix(hooks): add read-before-edit guard for non-Claude runtimes (#1645)
* fix(hooks): add read-before-edit guidance for non-Claude runtimes When models that don't natively enforce read-before-edit hit the guard, the error message now includes explicit instruction to Read first. This prevents infinite retry loops that burn through usage. Closes #1628 Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * fix(build): register gsd-read-guard.js in HOOKS_TO_COPY and harden tests The hook was missing from scripts/build-hooks.js, so global installs would never receive the hook file in hooks/dist/. Also adds tests for build registration, install uninstall list, and non-string file_path.
