* refactor(hooks): consolidate PostToolUse hooks into sync/async dispatchers
Replace 10 individual PostToolUse entries in hooks.json with two
consolidated dispatcher entries (post:dispatcher:sync /
post:dispatcher:async). The dispatcher's internal registry preserves
every hook ID, matcher, and profile, so ECC_DISABLED_HOOKS and
ECC_HOOK_PROFILE gating behave exactly as before.
Performance (Edit event, actual hooks.json commands spawned in
parallel like the harness does, median of 7 runs):
- Blocking hook latency: 81ms -> 49ms (~40% faster; 7 blocking
processes -> 1 sync dispatcher)
- Node processes per tool call: 10 -> 2 (7 blocking + 3 async
-> 1 sync + 1 async)
- observe-runner now runs in-process (~370ms) inside the async
dispatcher, which stays backgrounded (async: true, timeout 45s),
so it adds no user-facing latency.
Also:
- dashboard-web lists dispatcher-managed child hooks so the hook
inventory stays complete
- post-edit-console-warn refactored to export run() for in-process
dispatch while keeping standalone stdin behavior
- dispatcher stdin reading is multi-byte safe (StringDecoder) and
child hook exit codes propagate to the dispatcher exit code
* test(hooks): replace emoji literal with unicode escape for CI unicode safety check
* fix(hooks): adopt explicit cli() entrypoint and merge multi-hook stdout
Address Greptile review on #2494:
- Replace the non-standard 'require.main === undefined' guard with an
explicit exported cli(). The hooks.json bootstraps now call
require(s).cli(), so merely requiring the module (dashboard-web,
test runners, Jest, worker threads) can never trigger dispatch,
attach stdin listeners, or set process.exitCode.
- Replace last-writer-wins stdout with mergeHookStdout(): when several
hooks emit additionalContext envelopes they merge into a single
PostToolUse envelope; non-mergeable raw stdout keeps the last hook's
output and emits a stderr warning naming the dropped hook IDs, so
nothing is lost silently.
Also includes local formatter reformatting of the dispatcher and its
test file (no behavioral changes beyond the above).
* fix(hooks): keep post:bash:dispatcher phase reachable in minimal profile
The Greptile P1 premise was partially incorrect: sub-hooks without
explicit profiles default to standard,strict via parseProfiles()
(scripts/lib/hook-flags.js), so audit/cost logs never ran under the
minimal profile on main either — there is no user-visible regression.
However, main did spawn the bash dispatcher phase unconditionally and
let each sub-hook gate itself. Restore that semantic by opening the
outer registry gate to minimal,standard,strict so a future sub-hook
that opts into minimal is not silently blocked at the phase level.
Adds the previously missing minimal-profile async dry-run test.
* test(hooks): assert failing hook exit code propagates to real process status
Spawns the actual dispatcher subprocess with an injected failing hook
and asserts the OS-level exit status, stderr diagnostic, and suppressed
pass-through — closing the E2E gap CodeRabbit flagged on #2494.
* chore: retrigger CI (flaky windows powershell bootstrap test)
Generate the inline hook root resolver with single-quoted JavaScript literals so Windows Git Bash does not choke on nested escaped double quotes before Node starts. Refresh hooks.json and add regression coverage for parsed hook commands and installed hook manifests.
Remove unused loadInstallManifests import and prefix unused result
variable with underscore in selective-install tests. Add npx as an
approved command prefix in hook validation tests.
PR #344 replaced the blocking dev-server hook with auto-tmux-dev.js
which transforms commands into tmux sessions (exit 0) instead of
blocking them (exit 2). Updated 2 tests to match the new behavior.
- Fix MD012 trailing blank lines in commands/projects.md and commands/promote.md
- Fix MD050 strong-style in continuous-learning-v2 (escape __tests__ as inline code)
- Extract doc-file-warning hook to standalone script to fix hooks validator regex parsing
- Update session-end test to match #317 behavior (always update summary content)
- Allow shell script hooks in integration test format validation
All 992 tests passing.
Windows pipes raise EOF instead of EPIPE when the child process
exits before stdin finishes flushing. Added EOF to the ignored
error codes in runHookWithInput.
Integration tests were still passing CLAUDE_TRANSCRIPT_PATH as an env
var, but evaluate-session.js now reads transcript_path from stdin JSON.
Also improves strategic-compact skill with decision guide and survival table.
Core library fixes:
- session-manager.js: wrap all statSync calls in try-catch to prevent
TOCTOU crashes when files are deleted between readdir and stat
- session-manager.js: use birthtime||ctime fallback for Linux compat
- session-manager.js: remove redundant existsSync before readFile
- utils.js: fix findFiles TOCTOU race on statSync inside readdir loop
Hook improvements:
- Add 1MB stdin buffer limits to all PostToolUse hooks to prevent
unbounded memory growth from large payloads
- suggest-compact.js: use fd-based atomic read+write for counter file
to reduce race window between concurrent invocations
- session-end.js: log when transcript file is missing, check
replaceInFile return value for failed timestamp updates
- start-observer.sh: log claude CLI failures instead of silently
swallowing them, check observations file exists before analysis
Test fixes:
- Fix blocking hook tests to send matching input (dev server command)
and expect correct exit code 2 instead of 1
