Agent Performance Report - Week of 2026-09-27

[github-actions[bot]]

Executive Summary

• Metrics freshness: metrics/latest.json is still dated 2026-09-01 — 26 days stale, 16th
  consecutive affected run. Root cause (metrics-collector.md missing model-provider: github)
  remains unfixed on main (independently re-verified below). Full agent quality/effectiveness
  ranking stays blocked pending a fresh snapshot.
• What changed since last week: the systemic "diagnose-but-never-convert-to-PR" gap I flagged
  on 2026-09-25/26 is now formally tracked — Deep Report opened two concrete fix issues,
  #63656 (extend expires for P0/P1 trackers past
  1 day) and #63657 (give Workflow Health Manager
  a scoped create-pull-request safe-output). Both remain open and unmerged.
• The underlying defects have now self-expired a 3rd time without a fix landing: #63098
  (closed not_planned 2026-09-25), #63348 (closed not_planned 2026-09-26), #63556 (closed
  not_planned 2026-09-27T06:54:57Z per direct issue_read). No successor tracker has been filed
  yet as of this run.

Root-cause verification (independently re-checked against current `main`, not shared-memory notes)

Defect	File:Line	Status on main (verified via git blame)	Prior fix PRs
/usr/local/bin/npm symlink bind-mount crash	avenger.md:42	Still present — "/usr/local/bin/npm:/usr/local/bin/npm:ro"	#57946 (closed unmerged 2026-09-05)
Missing model-provider: github	metrics-collector.md:14-16	engine.id: codex still has no model-provider, paired with model: copilot/gpt-5.3-codex	none opened
Hardcoded retired model	gpclean.md:61	Still model: openai/gpt-5-codex	#58725 (merged 2026-09-05, but reverted back to the retired alias by a later commit — line is retired-model again as of main's current HEAD)

Fresh occurrence confirming gpclean is still broken: issue
#63763 (2026-09-27T03:31Z, run
§36291452078) — all 4 codex-harness
retries failed with Model 'gpt-5-codex' is retired... Did you mean 'gpt-5.3-codex'?.

search_pull_requests across all 3 filenames found no open or recently merged fix PR beyond the
already-known closed-unmerged #57946/#58722 and the reverted #58725.

Ecosystem Snapshot (from stale 2026-09-01 metrics, directional only)

• 297 total workflows tracked, 41 active in the snapshot window; 66 total safe outputs
  (24 issues, 1 PR, 41 comments, 0 discussions); overall success rate 91.7%.
• Active workflows with executed > 0 but success_rate < 0.8 in the snapshot: cjs (CI,
  command-gating — not an agentic failure), daily-firewall-report, daily-go-test-parallelizer,
  lint-monster — all three already tracked and root-caused by Workflow Health Manager as the
  cloud-hypervisor/redaction-crash family, not agent-quality defects.
• No agent produced enough fresh output volume in the (still-stale) snapshot to support a
  statistically meaningful quality/effectiveness re-ranking this week; deferring the full
  bottom-10 prompt audit until metrics/latest.json refreshes.

Behavioral Pattern Note

• Workflow Health Manager — repetition: the same 3 root-caused findings have now been
  re-diagnosed and re-filed as new tracking issues on 2026-09-24, 25, 26, and 27 without variation,
  because each expires: 1d tracker self-closes before conversion to a PR. This is a structural
  consequence of the expiry policy (already tracked in [deep-report] Extend expires policy for P0/P1 workflow-health-manager trackers past 1 day #63656/[deep-report] Give Workflow Health Manager a scoped create-pull-request safe-output for root-caused single-line config fixes #63657), not a quality defect in the
  diagnosis itself — WHM's root-cause evidence has been accurate and unchanged across all 4 cycles.

Recommendations

1. Merge [deep-report] Extend expires policy for P0/P1 workflow-health-manager trackers past 1 day #63656 (extend expires for P0/P1 workflow-health trackers past 1 day) — lowest
   effort, directly breaks the observed 3-cycle self-expiry loop. Expected impact: stops the
   same finding from being re-diagnosed weekly.
2. Merge [deep-report] Give Workflow Health Manager a scoped create-pull-request safe-output for root-caused single-line config fixes #63657 (scoped create-pull-request safe-output for Workflow Health Manager) —
   lets already-diagnosed single-line fixes land without waiting on generic Copilot-assignment,
   which has failed once already (attempted on [Workflow Health] 3 root-caused workflow failures: avenger npm-symlink, metrics-collector missing model-provider, gpclean retire #63098, 2026-09-24).
3. Apply the 3 one-line fixes directly as a stopgap while [deep-report] Extend expires policy for P0/P1 workflow-health-manager trackers past 1 day #63656/[deep-report] Give Workflow Health Manager a scoped create-pull-request safe-output for root-caused single-line config fixes #63657 are pending:
   remove the npm symlink mount line in avenger.md, add model-provider: github to
   metrics-collector.md, and change gpclean.md's model back to openai/gpt-5.3-codex.

Next Steps

1. Track [deep-report] Extend expires policy for P0/P1 workflow-health-manager trackers past 1 day #63656/[deep-report] Give Workflow Health Manager a scoped create-pull-request safe-output for root-caused single-line config fixes #63657 to merge; re-verify the 3 defects next run.
2. Resume full agent quality/effectiveness ranking once metrics/latest.json refreshes
   post-fix.
3. Continue monitoring daily-firewall-report/daily-go-test-parallelizer/lint-monster per
   Workflow Health Manager's cloud-hypervisor/redaction-crash tracking.
