Agent Performance Report - Week of 2026-09-28

[github-actions[bot]]

Executive Summary

• Agents analyzed: 0 newly re-scored (full ranking blocked — see below); prior rankings from 2026-09-01 snapshot remain the last valid baseline.
• Total outputs reviewed: 0 new safe outputs this run beyond verification reads (issues: 0, PRs: 0, comments: 0 created by this analysis)
• Average quality score: N/A this run (blocked on stale metrics)
• Average effectiveness score: N/A this run (blocked on stale metrics)
• Top performers: N/A (deferred pending fresh metrics)
• Needs improvement: Workflow Health Manager's fix-conversion pipeline (systemic gap, 4th cycle), Metrics Collector (root cause of the stale-metrics blocker), avenger, gpclean

Why full ranking is still blocked (17th consecutive run)

metrics/latest.json remains dated 2026-09-01 — now 27 days stale. This traces directly to
metrics-collector.md being one of the 3 workflows carrying a live, unfixed root cause (missing
model-provider: github), so it cannot refresh the metrics snapshot that this analysis depends on
for quality/effectiveness scoring. Until that fix lands, per-agent quality/effectiveness rankings
cannot be regenerated with fresh data, and this report continues to focus on independently
re-verifying the blocking root causes rather than re-stating a 27-day-old ranking as current.

Root-cause re-verification (independent, direct file reads this run)

#	File / Line	Defect	Status on main (verified 2026-09-28)	Fix
1	avenger.md:42	/usr/local/bin/npm:/usr/local/bin/npm:ro bind-mounts a symlink; sandbox rejects it ("Refusing to use symlink as bind mountpoint")	Still present — confirmed via direct sed/grep of current file	Remove the npm mount line; rely on existing /usr/local/bin/node + /usr/local/lib/node_modules mounts (diff from closed-unmerged #57946 still applies)
2	metrics-collector.md:14-16	engine: block sets only id: codex, omitting model-provider: github, while model: copilot/gpt-5.3-codex is used	Still present — confirmed by diffing against working siblings daily-go-test-parallelizer.md and api-consumption-report.md, both of which explicitly set model-provider: github	Add model-provider: github under engine:
3	gpclean.md:58-61	Hardcodes retired model: openai/gpt-5-codex	Still present, and produced a fresh failure today (issue #63913, run 36374058667, 2026-09-28T03:31Z — all 4 codex retries failed with retired_model error)	model: openai/gpt-5.3-codex

No merged fix PR was found for any of the 3 files (search_pull_requests across all 3 filenames
returns only the 2026-09-05 closed-unmerged #57946/#58722, whose diffs remain directly
applicable but were never merged).

Self-expiry loop status: 4th cycle confirmed, still no structural fix merged

Tracker	Filed	Closed	State reason
#63098	~2026-09-22	2026-09-25T06:56:34Z	not_planned (auto-expiry, no fix PR)
#63348	2026-09-25T04:46Z	2026-09-26T06:52:59Z	not_planned (auto-expiry, no fix PR)
#63556	2026-09-26T04:47Z	2026-09-27T06:54:57Z	not_planned (auto-expiry, no fix PR)
(none refiled as of this run)	—	—	4th cycle has no open successor tracker yet

This is the 4th consecutive self-expiry of the identical 3 findings, with no fix PR landing in
any cycle. The structural fixes proposed to break this loop remain open and unmerged, independently
re-confirmed this run via issue_read:

• [deep-report] Extend expires policy for P0/P1 workflow-health-manager trackers past 1 day #63656 — Extend expires policy for P0/P1 workflow-health-manager.md trackers past 1 day. Open, unmerged, no linked PR.
• [deep-report] Give Workflow Health Manager a scoped create-pull-request safe-output for root-caused single-line config fixes #63657 — Give Workflow Health Manager a scoped create-pull-request safe-output for root-caused single-line config fixes. Open, unmerged, no linked PR.

Both issues were filed 2026-09-26 by the Deep Report workflow, referencing this report series, and
have now carried over unresolved across 2 additional weekly reports (2026-09-27, 2026-09-28).

Behavioral Patterns

Problematic Patterns ⚠️

• Workflow Health Manager — repetition: filing near-identical re-confirmation trackers for the
  same 3 root causes every ~24h because expires: 1d forces re-diagnosis before any fix window can
  close. This is a structural/config pattern (the expires setting), not a prompt-quality defect in
  Workflow Health Manager itself — its diagnosis quality across all 4 cycles has been accurate and
  consistent (same exact line numbers, same exact diffs, each time).
• Ecosystem-wide — under-conversion: no meta-orchestrator currently holds a create-pull-request
  safe-output scoped for high-confidence, single-line config fixes. Two direct fix PRs for these
  exact defects (Prevent Avenger startup failure from npm symlink mount #57946, Fix Avenger gVisor startup failure #58722) were opened by a human/agent and closed unmerged on 2026-09-05 —
  the gap is in getting a fix merged, not in diagnosis or even PR drafting capability.

No over-creation, scope-creep, or inconsistency patterns were newly detected this run beyond
the above.

Recommendations

High Priority

1. Merge [deep-report] Extend expires policy for P0/P1 workflow-health-manager trackers past 1 day #63656 and [deep-report] Give Workflow Health Manager a scoped create-pull-request safe-output for root-caused single-line config fixes #63657 (or apply an equivalent structural fix) — Estimated effort: <15 min
   for [deep-report] Extend expires policy for P0/P1 workflow-health-manager trackers past 1 day #63656 (1-line frontmatter change), 2-4h for [deep-report] Give Workflow Health Manager a scoped create-pull-request safe-output for root-caused single-line config fixes #63657 (new safe-output block). Expected impact:
   breaks a 4-cycle self-expiry loop that has now blocked fresh metrics for 27 days and generated at
   least 4 near-duplicate P1 tracker issues.
2. Apply the 3 one-line/config fixes directly as an immediate stopgap, independent of the
   structural fix above:
   • avenger.md: remove the /usr/local/bin/npm mount line
   • metrics-collector.md: add model-provider: github under engine:
   • gpclean.md: change model: openai/gpt-5-codex → model: openai/gpt-5.3-codex
     Estimated effort: <15 min total (3 single-line diffs, already fully specified across 4 tracker
     issues). Expected impact: unblocks metrics-collector immediately, restoring fresh
     metrics/latest.json data and unblocking full agent quality/effectiveness ranking in this report
     series.
3. Do not re-file a 5th duplicate root-cause tracker. Any future occurrence of these 3 failure
   signatures should be consolidated as a comment on [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 (the structural fix) rather than a
   new tracker, to avoid further noise while the real fix is pending.

Medium Priority

1. Once metrics resume, re-baseline the full per-agent quality/effectiveness ranking from scratch
   rather than trusting the 2026-09-01 snapshot, since 27 days of ecosystem changes (new workflows,
   deprecated ones, prompt edits) will have accumulated.

Trends

• metrics/latest.json staleness: 27 days (↑ +1 day from last week's 26) — still blocked on the
  same root cause.
• Self-expiry cycle count for the 3 root causes: 4 (↑ +1 from last week's 3rd cycle) — no
  improvement; structural fix issues ([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) remain unmerged for the 2nd consecutive week.
• No new occurrence issues beyond [aw] GPL Dependency Cleaner (gpclean) failed #63913 (gpclean, 2026-09-28) attributable to these 3 root causes.

Actions Taken This Run

• Directly re-read avenger.md, metrics-collector.md, and gpclean.md on current main and
  diffed the metrics-collector engine: block against 2 working sibling workflows to independently
  confirm all 3 root causes remain unfixed.
• Confirmed via issue_read that [Workflow Health] 3rd re-confirmation: avenger npm-symlink, metrics-collector model-provider, gpclean retired model still unfixe #63556 closed not_planned (4th self-expiry, no fix PR) and that
  no successor tracker has been filed yet.
• Confirmed via issue_read that [deep-report] Extend expires policy for P0/P1 workflow-health-manager trackers past 1 day #63656 and [deep-report] Give Workflow Health Manager a scoped create-pull-request safe-output for root-caused single-line config fixes #63657 (the structural fixes) remain open and unmerged.
• Searched search_pull_requests across all 3 filenames; found no new merged fix beyond the
  already-known closed-unmerged Prevent Avenger startup failure from npm symlink mount #57946/Fix Avenger gVisor startup failure #58722.
• Created this weekly Agent Performance Report discussion.
• Did not file a 5th duplicate root-cause tracker (would self-expire per current expires: 1d
  policy without adding new information beyond what [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 already capture).

Next Steps

1. Merge or apply [deep-report] Extend expires policy for P0/P1 workflow-health-manager trackers past 1 day #63656 (expiry extension) and [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 capability).
2. Apply the 3 one-line stopgap fixes directly if the structural fix is not merged within 24-48h.
3. Once metrics-collector resumes producing fresh snapshots, regenerate the full per-agent
   quality/effectiveness ranking from current data rather than the 2026-09-01 baseline.
4. Continue monitoring for a 5th self-expiry cycle; if it occurs, escalate directly to a maintainer
   rather than filing another tracker.
