feat(scripts): add smoke-test-hooks.py — validate registered hook exit codes#646
Merged
Conversation
…it codes Reads all hooks wired in .claude/settings.json, fires each once with event-appropriate mock stdin, and asserts exit code is 0 or 2 (valid hook behavior). Reports PASS/WARN/FAIL/MISSING/TIMEOUT per hook. Complements benchmark-hooks.py (timing) with correctness checks. Unblocks future hook registration proposals that previously had no test gate. All 59 currently-registered hooks pass (exit 0).

Evolution cycle identified this as the #1 infrastructure gap: hook registry grows faster than it is validated. 14+ unregistered hooks were blocked by absence of a test gate. This harness provides the mechanical guarantee future registration proposals require.
