[Agent Perf] Impeccable Skills Reviewer still failing after CLI hang-on-exit fix merged (PR #48499)

[github-actions]

Summary

PR #48499 ("fix: add post-result watchdog to codex_harness to prevent CLI hang-on-exit") merged 2026-07-28 10:08 UTC, intended to resolve the recurring 100%-AR CLI hang-on-exit cluster affecting Impeccable Skills Reviewer, PR Code Quality Reviewer, and Test Quality Sentinel (tracked in #44298, #48192).

Evidence the fix did not fully resolve the issue:

• Issue [aw] Impeccable Skills Reviewer failed #48612 ("Impeccable Skills Reviewer failed") was created 2026-07-28 12:41 UTC — over 2 hours after the fix merged.
• Issue [aw] Impeccable Skills Reviewer produced no safe outputs #48494 ("Impeccable Skills Reviewer produced no safe outputs") also open, same failure family (agent job succeeds but produces no safe outputs).
• Current run sample (last 100 CI runs): Test Quality Sentinel and PR Code Quality Reviewer each show only 1 run, both in_progress/unresolved — insufficient signal to confirm the fix landed cleanly for those workflows too.

Recommendation

1. Confirm whether run 30359619958 (linked from [aw] Impeccable Skills Reviewer failed #48612) actually exercised the patched codex_harness watchdog, or ran against a pre-fix commit/cache.
2. If the watchdog is active but outputs are still empty, the root cause may be a second, distinct failure mode (no-safe-outputs vs. hang-on-exit) rather than the same bug — worth splitting into a new investigation rather than re-attributing to the fixed issue.
3. Add a short post-fix monitoring window (3-5 runs) before closing [aw] PR Code Quality Reviewer + Test Quality Sentinel — 100% AR (CLI hang-on-exit) #44298/Content Moderation workflow: third regression to 100% AR (CLI hang-on-exit) #48192 as resolved.

Impact

Quality/effectiveness score for Impeccable Skills Reviewer remains near 0% effectiveness this week (0/1 successful in sampled runs), consistent with prior weeks flagged as a deprecation candidate. Confirming whether the fix landed will determine if deprecation is still warranted.
