Agent Performance Report - 2026-09-06 (stale root-cause corrections + metrics volatility)

Agent Performance Report — 2026-09-06

Executive Summary

• Data source note: Shared metrics (metrics/latest.json) are timestamped 2026-09-01, but memory notes (agent-performance-latest.md, shared-alerts.md, workflow-health-latest.md) are stale, dated 2026-07-08 — a ~2 month gap. This report reconciles both against live GitHub state.
• Active workflows (latest snapshot): 41 of 297 total (down sharply from 154–247 active on Aug 20–22 — see Ecosystem Volatility below).
• Overall success rate (Sep 1 snapshot): 91.7% (up from 42–84% in the Aug 20–22 window).
• Top performers (Sep 1, 100% success, executed runs > 0): avenger, aw-failure-investigator, daily-trajectory-grader-implementer, pr-sous-chef (also only agent producing safe outputs: 1 issue + 4 comments), copilot.
• Needs improvement: cjs (50% success, 2 executed), daily-firewall-report, daily-go-test-parallelizer, lint-monster (all 0% success, 1 executed run each, real failures not gating).
• Command-gated (not failures): q, squad, agentic_commands, ai-moderator — high action_required/skipped counts are expected trigger-gating behavior, not activation-refused defects.

Stale Root-Cause Corrections (Root-Cause Hygiene)

Verified against live GitHub state — several "pending fix" citations carried in shared memory are stale and should be removed/replaced:

1. PR fix: reduce post-completion idle watchdog and add cleanup timeouts to prevent Copilot CLI hang on exit #44254 (Copilot CLI hang-on-exit fix for Impeccable/PR-Code-Quality/Test-Quality-Sentinel/Matt-Pocock reviewers) — MERGED 2026-07-08. Memory files still list this as "open" / "CRITICAL — merge this PR." Action: remove stale citation. Since Sep 1 snapshot shows these reviewers now at 100% success with executed runs, the fix appears to have worked — no new action needed, but the alert text is misleading and should be retired.
2. PR Add shared prompt quality gate for plateaued agent-review workflows #43527 (shared quality-gate prompt fragment for Agentic Performance Analyzer / reviewer prompts) — MERGED 2026-07-05. shared-alerts.md still cites it as "not yet merged — URGENT" blocking the Q workflow. This is now incorrect; Q's action_required rate is a designed command-gating behavior (slash-command workflow), not a quality-gate defect — re-diagnose from trigger config, not from PR Add shared prompt quality gate for plateaued agent-review workflows #43527 status.
3. PR fix: reclaim root-owned sandbox firewall dirs to prevent EACCES on reused runners #44276 (sandbox firewall EACCES ownership fix) — MERGED 2026-07-09. No longer "open"; Smoke CI EACCES citations referencing this as pending should be dropped from future alerts unless failures recur post-merge.
4. Issue [CGO] Workflow failure on main - Run #11644 #38777 (CGO escalation ticket, repeatedly cited across both memory files as the CGO tracking issue) — returns 404, does not exist in github/gh-aw. This is a broken/invalid reference (possibly a différent-repo issue number or a fabricated one). Action: stop citing [CGO] Workflow failure on main - Run #11644 #38777; if CGO instability recurs, file a fresh issue instead of commenting on a non-existent ticket.
5. Issue [aw] Metrics Collector failed #43292 (Metrics Collector engine failure) — closed not_planned on 2026-07-04, not actually fixed. Current Sep-1 snapshot still shows metrics-collector: executed=0. This root cause is legitimately still unresolved and should continue to be tracked, but framed as "closed without a fix, recommend reopening or filing new issue" rather than "pending fix."

Ecosystem Volatility — Possible Metrics Collector Instability

Date	Active workflows	Total safe outputs	Success rate
2026-08-20	66	319	84.4%
2026-08-21	154	718	83.6%
2026-08-22	247	67	42.3%
2026-09-01	41	66	91.7%

The active-workflow count swings 4x week-over-week (66 → 247 → 41) while safe-output volume doesn't track proportionally (peaks at 718 on a 154-active day, drops to 66-67 on both the 247-active and 41-active days). Combined with the confirmed Metrics Collector engine failure (issue #43292, unresolved), this pattern is more consistent with inconsistent/partial metrics collection than genuine week-over-week ecosystem swings. Recommend treating absolute active-workflow and safe-output counts from this period as unreliable until Metrics Collector reliability is restored, and prioritizing a fix/reopen for #43292.

Current Snapshot — Workflows With Real (Non-Gated) Failures

Workflow	Executed	Success rate	Note
daily-firewall-report	1	0%	Real failure, 1 executed run
daily-go-test-parallelizer	1	0%	Real failure, 1 executed run
lint-monster	1	0%	Real failure, 1 executed run
cjs	2	50%	CI workflow; 1 success/1 fail, plus 4 action_required (approval-pending, not agentic AR)

Only pr-sous-chef produced safe outputs in this snapshot (1 issue, 4 comments) — most active workflows executed with zero created issues/PRs/comments, consistent with monitoring/CI-style workflows rather than content-generating agents.

Recommendations

1. Clean shared memory now: Remove stale PR fix: reduce post-completion idle watchdog and add cleanup timeouts to prevent Copilot CLI hang on exit #44254/Add shared prompt quality gate for plateaued agent-review workflows #43527/fix: reclaim root-owned sandbox firewall dirs to prevent EACCES on reused runners #44276 citations and the broken [CGO] Workflow failure on main - Run #11644 #38777 reference from shared-alerts.md and workflow-health-latest.md; replace with current status (merged/resolved) so future runs don't re-cite them as pending. (High priority, near-zero effort, prevents repeated misattribution.)
2. Investigate Metrics Collector reliability (issue [aw] Metrics Collector failed #43292, closed not_planned but unresolved) — reopen or file a fresh issue; until fixed, ecosystem-level trend numbers (active workflow counts, safe-output totals) should not be used for week-over-week comparisons.
3. Triage the three genuine 0%-success single-run failures (daily-firewall-report, daily-go-test-parallelizer, lint-monster) — each has only one executed run in this window, so root cause is not yet established; file targeted issues after confirming they aren't transient.
4. No action needed for command-gated workflows (q, squad, agentic_commands, ai-moderator) — their high AR/skipped ratios are designed trigger-gating; do not file new issues without checking activated-run-only success rate first.

Next Steps

• Update shared-alerts.md / workflow-health-latest.md to drop resolved/broken citations (see corrections above).
• File or reopen an issue for Metrics Collector instability if not already tracked as active.
• Recheck daily-firewall-report, daily-go-test-parallelizer, lint-monster failures in the next collection window before filing new issues (single-run sample size).
