Agent Performance Report - Week of 2026-09-01

[github-actions[bot]]

Executive Summary

• Data caveat: The only fresh metrics snapshot in shared memory is metrics/latest.json dated 2026-09-01T02:50:27Z — 6 days stale relative to this run (2026-09-07). No 2026-09-0[2-7] daily files exist. All scores below are single-day/single-run snapshots, not weekly aggregates. Historical agent-performance-latest.md/shared-alerts.md content is from Jul 8, ~2 months old; those entries are stale and have been re-verified, not restated blindly.
• Workflows tracked: 311 total, 41 active in the Sep 1 snapshot, most with only 1 executed run that day.
• Good news confirmed: All four PR-review agents previously reported at 100% AR due to the "CLI hang-on-exit" bug (Impeccable Skills Reviewer, PR Code Quality Reviewer, Test Quality Sentinel, Matt Pocock Skills Reviewer) now show 1/1 success (100%) in the Sep 1 snapshot. The cited fix, PR fix: reduce post-completion idle watchdog and add cleanup timeouts to prevent Copilot CLI hang on exit #44254 ("reduce post-completion idle watchdog and add cleanup timeouts"), is confirmed merged 2026-07-08. Design Decision Gate, previously a deprecation candidate at 100% AR, is also 1/1 success.
• Q workflow root-cause correction: The Jul 8 alerts described Q at "19/24 AR (79%)" as an activation failure blocked on quality-gate PR Add shared prompt quality gate for plateaued agent-review workflows #43527. That PR is confirmed merged 2026-07-05. Q is a slash_command-triggered workflow (fires on every issue/comment/discussion event, gated by pre_activation); its Sep 1 snapshot (0 executed / 4 skipped / 2 AR out of 6 total) reflects expected command gating, not an activation defect. This root cause should be retired from the alert log — see updates below.
• New issues since Jul 8 (Sep 1 snapshot): daily-firewall-report, daily-go-test-parallelizer, and lint-monster each show 1 failed / 1 total (0% success) — single-run signal only, needs a second data point before filing.

Performance Rankings (Sep 1 snapshot, executed-run basis)

Recovered / Stable ✅

Agent	Executed	Success rate	Notes
Impeccable Skills Reviewer	1/1	100%	CLI hang fix (#44254) holding
PR Code Quality Reviewer	1/1	100%	CLI hang fix (#44254) holding
Test Quality Sentinel	1/1	100%	CLI hang fix (#44254) holding
Matt Pocock Skills Reviewer	1/1	100%	No longer a deprecation candidate on this data
Design Decision Gate	1/1	100%	Recovered
pr-sous-chef	3/3	100%	Only agent with safe outputs this window (1 issue, 4 comments)
aw-failure-investigator, daily-trajectory-grader-implementer, avenger, issue-monster, copilot	2-4/2-4	100%	Stable

Command/mention-gated (expected, not failures) ⏱️

Agent	Total	Executed	Skipped/AR
q	6	0	4 skipped, 2 AR (command gating, expected)
ai-moderator	8	0	4 skipped, 4 AR — mixed with real prior engine failures (Codex 404), needs re-triage vs. gating
squad	7	0	4 skipped, 3 AR — check trigger type before treating as failure

Needs Watching (single-run failures, insufficient for issue filing yet) 📉

Agent	Executed	Result
daily-firewall-report	1/1	Failed
daily-go-test-parallelizer	1/1	Failed
lint-monster	1/1	Failed

CI (not agentic) — informational only

• CWI, CGO, CJS, CI: run under GitHub Actions approval gating semantics per repo convention; CJS shows 2/2 executed with 1 success/1 failed — small sample, watch only.

Root-Cause Hygiene Applied This Run

Re-verified stale entries from shared-alerts.md (dated Jul 8) against current PR state:

• PR fix: reduce post-completion idle watchdog and add cleanup timeouts to prevent Copilot CLI hang on exit #44254 (CLI hang-on-exit fix) — merged 2026-07-08. Metric evidence (all 4 review agents now 100% success) confirms the fix landed and worked. Removing "DO NOT RE-FILE" watch entries for Impeccable/PR Code Quality/Test Quality Sentinel/Matt Pocock — issue is resolved.
• PR Add shared prompt quality gate for plateaued agent-review workflows #43527 (Q quality gate) — merged 2026-07-05. The "Q workflow persistent AR (79%)" root cause is stale; Q's non-executed runs are slash_command gating by design. Reclassifying, not re-filing.
• PR fix: reclaim root-owned sandbox firewall dirs to prevent EACCES on reused runners #44276 (Smoke CI sandbox EACCES fix) — merged 2026-07-09. Removing from active watch list; no Sep 1 data point to confirm regression-free but no re-report needed without fresh failure evidence.
• Design Decision Gate — no longer scored as 100% AR; deprecation-candidate label retired pending further data.

Recommendations

High Priority

1. Fix stale metrics collection — metrics-collector shows executed: 0 in the Sep 1 snapshot and no daily files exist for Sep 2–7. Weekly analysis is materially degraded without daily granularity. Recommend investigating metrics-collector scheduling/engine health directly.
2. Confirm ai-moderator and squad trigger types — before their AR/skip counts are attributed to real failures vs. expected command/mention gating (like q), check their frontmatter on: triggers. Misclassifying gated workflows as failing risks re-opening already-resolved issues.

Medium Priority

3. Second-observation check on daily-firewall-report, daily-go-test-parallelizer, lint-monster — each has only one failed run recorded. Wait for the next daily snapshot before filing individual issues; if failures repeat, file with logs from both runs.

Trends

• Cannot compute week-over-week trends: no daily snapshots exist between 2026-08-22 and 2026-09-01, and none after Sep 1. Historical Jul 8 scores (Q:63 E:64 H:63) are too old to serve as a valid baseline comparison for this run.

Actions Taken This Run

• Verified and closed out 3 previously-flagged P1 items (CLI hang cluster, Q quality gate, Smoke CI EACCES) as resolved via merged PRs + recovered metrics.
• Reclassified Q workflow's gating behavior as expected rather than a persistent failure.
• Did not file new improvement issues — no agent has ≥2 data points of confirmed regression this window; filing now would risk duplicating stale reports.
• Updated shared memory (shared-alerts.md, agent-performance-latest.md) to remove resolved items and record current gaps.

Next Steps

1. Prioritize restoring daily metrics collection (metrics-collector engine health).
2. Re-run this analysis once fresh daily snapshots resume (Sep 2 onward) to compute real trends.
3. Watch daily-firewall-report / daily-go-test-parallelizer / lint-monster for a second consecutive failure before filing.
4. Confirm ai-moderator/squad trigger semantics to avoid false-positive failure attribution.
