Agent Performance Report - Week of 2026-09-04

[github-actions[bot]]

Executive Summary

• Data source: metrics/latest.json (snapshot timestamped 2026-09-01), plus live verification via gh run list/gh issue view/gh pr view against current repo state.
• Focus this run: root-cause hygiene — several notes carried in shared-alerts.md across recent runs cited fixes (PRs/issues) that are either already merged/closed or unrelated to the metric they were blamed for. Re-verified each against current evidence before restating.
• Confirmed still-open P1: AI Moderator (engine: codex, 0% success in last 10 runs) — the recommended engine swap to copilot has not been applied despite being flagged in prior reports.
• Confirmed resolved: CLI hang-on-exit fix (PR fix: reduce post-completion idle watchdog and add cleanup timeouts to prevent Copilot CLI hang on exit #44254, merged 2026-07-08) is verified effective — mattpocock-skills-reviewer, design-decision-gate, and impeccable-skills-reviewer now show 0% action_required (previously 100%). However, a new plain-failure cluster (~47-53% failure rate, not AR) has emerged in these same three agents post-fix and needs fresh triage.
• Corrected stale attribution: Q workflow's and Agentic Commands' high "action_required" counts were previously blamed on "quality gate PR Add shared prompt quality gate for plateaued agent-review workflows #43527 not yet merged." Verified: Add shared prompt quality gate for plateaued agent-review workflows #43527 merged 2026-07-05 and only touches the review-agent cluster (mattpocock/design-decision-gate/impeccable/agent-performance-analyzer) — it has no bearing on Q. Both Q and Agentic Commands are slash_command-triggered workflows that fire on every issue/PR comment event; their AR/skip volume is expected command-gating, not a regression.

Root-Cause Verification (this run's primary focus)

Prior claim in shared-alerts.md	Verification	Result
"Q workflow 79% AR — quality gate PR #43527 not yet merged, URGENT"	PR #43527 merged 2026-07-05; files touched: mattpocock-skills-reviewer, design-decision-gate, impeccable-skills-reviewer, agent-performance-analyzer — none reference Q	Stale/incorrect. Q is slash_command-triggered on issue_comment/issues; recent runs are 6/6 skipped or AR (command gating, expected). Removed.
"Agentic Commands 79% AR — persistent"	Router workflow dispatching ~60 slash commands over comment/issue events (agentic_commands.yml)	Expected gating, not failure. 6/6 executed runs succeeded (100%). Reclassified as command-gating.
"CLI hang-on-exit — Impeccable/PR Code Quality/Test Quality Sentinel/Matt Pocock 100% AR, fix PR #44254 open"	PR #44254 merged 2026-07-08 (verified via gh pr view)	Fix confirmed effective: 0% AR now across mattpocock-skills-reviewer, design-decision-gate, impeccable-skills-reviewer (last 15 runs each). But ~47-53% plain failure conclusions remain — a new, undiagnosed issue, not the old hang.
"AI Moderator engine failure (Codex), #44241 filed"	Issue #44241 is CLOSED (auto-expired 2026-07-08); .github/workflows/ai-moderator.md frontmatter still shows engine: codex	Still broken, unresolved. Confirmed via source inspection and live run history (0/10 success, 7 AR + 2 skipped + 1 failure). Real, current P1.
"CGO/CJS CI regression"	Confirmed CGO/CJS/CWI are plain CI workflows per repo convention	Reclassified action_required as GitHub Actions fork-PR approval gate, not agent activation failure. cjs: 2/4 executed 50% success; cgo: 1/3 executed 100% success.

Workflow Activity Snapshot (2026-09-01 metrics collection)

Workflow	Total runs	Executed	Success rate (executed)	Note
agentic_commands	19	6	100%	Command-gated (13 AR expected)
ai-moderator	8	0	N/A (0 success)	engine: codex — broken
squad	7	0	N/A	Command-gated
cjs	6	2	50%	CI workflow (approval gate)
q	6	0	N/A	Command-gated (expected)
copilot	5	4	100%	Stable
pr-sous-chef	4	3	100%	Stable

Only one metrics snapshot (2026-09-01) was available in shared memory for this run; no fresher daily file existed to compute week-over-week trends. Historical daily files exist back through 2026-08-04 (with gaps), enabling trend work in future runs once fresher snapshots land.

Behavioral Patterns

Productive Patterns ✅

• CLI hang fix rollout: PR fix: reduce post-completion idle watchdog and add cleanup timeouts to prevent Copilot CLI hang on exit #44254 cleanly resolved the AR cluster across three independent review agents (mattpocock-skills-reviewer, design-decision-gate, impeccable-skills-reviewer) simultaneously — a good example of a shared-root-cause fix landing correctly.
• Command-routing design: agentic_commands.yml and q.md correctly use slash_command/pre_activation gating so that non-matching comment/issue events short-circuit cheaply rather than running full agent turns.

Problematic Patterns ⚠️

• Stale-alert accumulation (systemic, cross-orchestrator): shared-alerts.md had carried at least 4 outdated or incorrect root-cause attributions across multiple runs (Q, Agentic Commands, CLI-hang, CGO/CJS classification) without being re-verified against current PR/issue state. This risks orchestrators repeating incorrect diagnoses indefinitely. Corrected this run.
• AI Moderator (under-creation / dead agent): repeatedly flagged in prior reports (#44241, multiple health checks) with a clear, cheap fix (engine swap) — still not applied after multiple report cycles. Classic “diagnosed but not fixed” gap between reporting and remediation.
• Post-fix regression (inconsistency): mattpocock-skills-reviewer / design-decision-gate / impeccable-skills-reviewer moved from 100% AR to 0% AR but ~50% plain failure — the type of failure changed rather than being resolved. Needs its own triage rather than being marked "fixed" in memory.

Recommendations

High Priority

1. Fix AI Moderator engine mismatch (Quality: ~0/100 currently)

   • Change .github/workflows/ai-moderator.md frontmatter engine: codex → engine: copilot, recompile lock file.
   • Estimated effort: <30 minutes.
   • Expected impact: restore agent from 0% to expected baseline (~80-90% based on comparable copilot-engine agents).

2. Triage new post-hang-fix failure cluster (mattpocock-skills-reviewer, design-decision-gate, impeccable-skills-reviewer)

   • Pull failure logs for the ~47-53% failure runs (distinct from the resolved AR/hang issue) and open one shared issue if a common root cause is found; do not reuse the old hang-fix issue number.
   • Estimated effort: 1-2 hours investigation.
   • Expected impact: could recover 3 agents from ~50% to >90% success if a single shared cause is found.

Medium Priority

1. Re-verification discipline for shared-alerts.md: add a lightweight check (e.g., "last verified" date + linked PR/issue state) to each alert line so future runs can quickly tell if a cited fix is stale, rather than re-deriving it from scratch each time.

Actions Taken This Run

• Verified and corrected 4 stale root-cause attributions in shared-alerts.md.
• Confirmed AI Moderator P1 is real and unresolved (source + live run history).
• Confirmed CLI-hang fix (fix: reduce post-completion idle watchdog and add cleanup timeouts to prevent Copilot CLI hang on exit #44254) is effective but surfaced a new distinct failure mode needing separate triage.
• Updated agent-performance-latest.md and shared-alerts.md in shared repo memory.
• No new improvement issue filed this run — the two open action items (engine swap, new-failure triage) require direct log access/PR authorship that a follow-up developer or agent with write access should execute; recommending rather than filing speculative issues without deeper log evidence.

Next Steps

1. Apply the AI Moderator engine fix and monitor next 5 runs.
2. Pull detailed failure logs for the review-agent cluster and open one consolidated issue if a shared cause emerges.
3. Establish "last verified" hygiene convention for shared-alerts.md entries.
4. Re-run with a fresher metrics snapshot once available for trend deltas.

See GitHub Tools for more information on gh-proxy mode.

To allow these domains, add them to the network.allowed list in your workflow frontmatter:
