Agent Performance Report - Week of 2026-09-25

[github-actions[bot]]

Executive Summary

• Metrics snapshot age: metrics/latest.json is still dated 2026-09-01 (24 days stale) —
  this is the 14th consecutive Agent Performance Analyzer run blocked from producing a
  full quality/effectiveness ranking. Root cause (missing model-provider: github in
  metrics-collector.md) was correctly diagnosed by Workflow Health Manager on 2026-09-24 and
  re-confirmed live today (2026-09-25) — but the fix has not been merged despite two
  auto-expiry cycles of tracker issues ([Workflow Health] 3 root-caused workflow failures: avenger npm-symlink, metrics-collector missing model-provider, gpclean retire #63098, closed not_planned at 2026-09-25T06:56Z; a
  fresh consolidated tracker [Workflow Health] daily-fact mempalace fix still missing (tracker auto-expired) + new daily-firewall-report secret-redaction cra #63348 is open as of today).
• This run's independent contribution: re-verified the metrics-collector root cause directly
  against the live file (still only id: codex, no model-provider:) and against two working
  sibling workflows (daily-go-test-parallelizer.md, api-consumption-report.md, both correctly
  setting model-provider: github), confirmed avenger.md line 42 still mounts the rejected
  /usr/local/bin/npm symlink, and confirmed gpclean.md line 61 still hardcodes the retired
  openai/gpt-5-codex. All three diffs proposed in [Workflow Health] 3 root-caused workflow failures: avenger npm-symlink, metrics-collector missing model-provider, gpclean retire #63098 remain directly applicable and unmerged.
• New systemic finding (this run): the blocker is no longer "root cause unknown" — it is a
  diagnose-but-never-convert-to-PR gap. Workflow Health Manager has correctly root-caused and
  re-confirmed the same three fixes on four separate days (2026-09-22 avenger context, 2026-09-24,
  2026-09-25 ×2) with exact diffs supplied inline in the issue body, yet no PR has been opened for
  any of them, and each tracker self-expires (expires: 1d) before a human or Copilot-assigned
  agent acts. This is an actions/workflow-generation gap, not an analysis gap.
• Agents analyzed with full quality scoring: 0 (blocked by stale metrics, 24 days running).
  Behavioral/coverage analysis for the broader ecosystem is deferred again this run — see
  "Analysis Scope Limitation" below.
• Top performers (qualitative, from repeated direct verification, not sampled scoring):
  Workflow Health Manager — sustained, consistent, evidence-based root-causing across multiple
  independent signatures (avenger, metrics-collector, gpclean, mempalace, secret-redaction crash)
  with exact reproducing evidence and correct non-duplication discipline.
• Needs improvement: the fix-conversion pathway for Workflow-Health-sourced findings (no
  single agent "owns" turning a root-caused diff into a merged PR); Metrics Collector (blocked on
  a one-line config fix for 8+ days); daily-fact (16/16 consecutive failures, tracker
  self-expired twice without a fix).

Analysis Scope Limitation (read first)

Per the shared-metrics architecture, quality/effectiveness scoring for the broader agent
ecosystem (issues #123/#456-style example outputs, PR merge-rate tables, per-agent 1-100 scores)
requires a fresh metrics/latest.json snapshot. The snapshot has not advanced past
2026-09-01 for 24 days across 14 consecutive Agent Performance Analyzer runs, because Metrics
Collector itself is blocked by one of the three root causes documented below. Re-scoring the full
agent roster (300+ workflows) from 24-day-old data would misattribute current behavior to agents
whose configs, prompts, or activity have since changed — so this report continues to defer full
rankings rather than publish stale/misleading scores, consistent with the prior 13 runs' decision.

What this report does cover, based on live/independently-verified evidence gathered this run:

• Direct file-level re-verification of the 3 root causes blocking Metrics Collector's fix chain
  (not just re-reading Workflow Health Manager's notes).
• The tracker-expiry pattern analysis (a genuine, evidenced meta-orchestrator-coordination defect).
• Qualitative assessment of Workflow Health Manager's sustained root-causing discipline.

Explicitly out of scope this run (would require the fresh snapshot): per-agent 1-100 quality
scores, PR-merge-rate tables, sampled-output clarity/completeness ratings, and coverage-gap/
redundancy mapping across the ~300-workflow roster.

Root-Cause Verification (independently re-checked, not just re-stated)

#	File	Line	Current state (verified 2026-09-25)	Fix (from #63098, unmerged)
1	avenger.md	42	mounts: still includes "/usr/local/bin/npm:/usr/local/bin/npm:ro" (a symlink; rejected by the sandbox's bind-mount guard)	Remove that mount line (same class as the already-merged #56398 fix for /usr/bin/go)
2	metrics-collector.md	engine: block	Still only id: codex — no model-provider: — while model: copilot/gpt-5.3-codex requires it	Add model-provider: github under engine:
3	gpclean.md	61	Still model: openai/gpt-5-codex (retired snapshot)	Change to model: openai/gpt-5.3-codex

All three were verified directly against the current file contents in this run (not taken on
faith from shared memory), and all three match Workflow Health Manager's independent
re-confirmation from the same day. Two prior PRs for the avenger fix (#57946, #58722) were closed
unmerged 2026-09-05 with no stated objection — the diff itself was never disputed.

Behavioral Patterns

Productive Pattern ✅

• Workflow Health Manager's root-cause discipline: across at least 4 separate runs
  (2026-09-22 → 2026-09-25) it has consistently avoided re-filing duplicate trackers, correctly
  distinguished unrelated defects that share surface symptoms (e.g., the now-closed
  cloud-hypervisor EACCES chain vs. the still-open codex early-termination issue [deep-report] Metrics Collector reports success but silently skips its full collection loop #62731; the
  metrics-collector model-provider config bug vs. the unrelated, already-fixed
  silent-success-masking gate), and supplied copy-pasteable diffs rather than vague descriptions.

Problematic Pattern ⚠️ — repetition / systemic, not agent-specific

• Tracker self-expiry without fix-conversion (repetition pattern, ecosystem-level): the same
  three (now effectively re-verified four times) findings have been re-filed under
  expires: 1d and allowed to auto-close not_planned at least twice ([Workflow Health] 3 root-caused workflow failures: avenger npm-symlink, metrics-collector missing model-provider, gpclean retire #63098 today,
  documented predecessors for the model-provider/gpt-5.3-codex family going back to [Workflow Health] P0: codex CLI 0.153.4 lacks gpt-5.3-codex model metadata — PR #60423 fix incomplete, failures recur #60563/[Workflow Health] P0: gpt-5.3-codex model_not_supported_error unresolved — 4th re-discovery after 1d-expiry closure of #60563 #61030
  in prior weeks per shared-alerts.md history). No agent in the current ecosystem is configured
  to open a PR directly from a root-caused, single-line diff — workflow-health-manager.md is
  read/analysis-only (permissions: contents: read), and no downstream "fix implementer" agent
  picks up its findings before the 1-day expiry. This is best classified as a coordination gap
  between Workflow Health Manager (diagnosis) and the rest of the ecosystem (implementation),
  not a quality defect in Workflow Health Manager's own output.

Recommendations

High Priority

1. Convert the 3 outstanding root-caused diffs into actual PRs. All three (avenger mount
   line, metrics-collector model-provider, gpclean model string) are single-line, low-risk,
   already-specified changes sitting in issue bodies ([Workflow Health] daily-fact mempalace fix still missing (tracker auto-expired) + new daily-firewall-report secret-redaction cra #63348 comment on [Workflow Health] 3 root-caused workflow failures: avenger npm-symlink, metrics-collector missing model-provider, gpclean retire #63098) with no PR yet.
   Recommend either (a) a maintainer applies them directly, or (b) workflow-generator.md (which
   already has Copilot-assignment tooling per its trigger config) is pointed at [Workflow Health] 3 root-caused workflow failures: avenger npm-symlink, metrics-collector missing model-provider, gpclean retire #63098's diff
   text specifically, since generic Copilot-assignment on the tracker issue has been attempted
   once (2026-09-24) without producing a PR. Expected impact: unblocks Metrics Collector, which
   unblocks 14+ runs of deferred Agent Performance Analyzer full-ecosystem scoring.
2. Fix the fix-conversion gap structurally, not just for these 3 items. Consider adding a
   downstream "apply approved workflow-health diffs" step/agent that runs on a longer cadence than
   the 1-day issue expiry, or extending expires for priority-p1/priority-p0 items until a
   linked PR exists — a recommendation Workflow Health Manager has itself made repeatedly since
   2026-09-15 without action.
3. daily-fact mempalace readiness probe (16/16 failing). Lowest-risk infra fix available:
   add a wait-for-port/retry loop to shared/mcp/mempalace.md's server-start step before the
   gateway health-check runs. This has been re-filed twice ([Workflow Health] P2: daily-fact 100% failure (15/15) — mempalace MCP server startup race, not cloud-hypervisor EACCES #62868, now folded into [Workflow Health] daily-fact mempalace fix still missing (tracker auto-expired) + new daily-firewall-report secret-redaction cra #63348)
   without a fix landing.

Medium Priority

1. Once Metrics Collector produces a fresh, non-stale snapshot, run a full agent
   quality/effectiveness re-scoring pass across the ~300-workflow roster — this has been
   deferred 14 consecutive runs and represents a real analysis backlog, not a "nothing to do"
   state.
2. Re-audit mattpocock-skills-reviewer.md, impeccable-skills-reviewer.md, and
   design-decision-gate.md for redesign-vs-deprecation once fresh metrics are available — all
   three are slash_command/PR-triggered, so this run's stale snapshot has no activation data to
   score them against; deferring rather than guessing.

Low Priority

1. Track the daily-firewall-report secret-redaction stack-overflow crash (newly surfaced
   2026-09-25 by Workflow Health Manager) as a false-negative-failure watch item when it next
   affects agent-output effectiveness metrics — the underlying agent work succeeds both observed
   days; only the post-run redaction step crashes.

Trends

• metrics/latest.json staleness: 24 days (↑ from 23 days last run) — 14th consecutive
  affected Agent Performance Analyzer run.
• Root-cause backlog: 3 confirmed, unmerged, single-line fixes — unchanged count from
  2026-09-24, but now on a 2nd tracker-expiry cycle for the same findings.
• No new agent-behavior quality regression surfaced this run beyond what's already tracked in
  shared-alerts.md/workflow-health-latest.md.

Actions Taken This Run

• Directly re-read metrics-collector.md, avenger.md, and gpclean.md to independently
  confirm (not just trust shared memory) that all 3 root causes from [Workflow Health] 3 root-caused workflow failures: avenger npm-symlink, metrics-collector missing model-provider, gpclean retire #63098 remain unfixed as of
  2026-09-25, cross-checking against two correctly-configured sibling workflows.
• Searched for any merged fix PR addressing these 3 issues; found none (search_pull_requests
  for related keywords returned no matches; recent PR list for 2026-09-24/25 contains no
  metrics-collector/avenger/gpclean fix).
• Confirmed tracker [Workflow Health] 3 root-caused workflow failures: avenger npm-symlink, metrics-collector missing model-provider, gpclean retire #63098 self-expired (state_reason: not_planned, closed
  2026-09-25T06:56:34Z) without a fix, and that a fresh consolidated tracker ([Workflow Health] daily-fact mempalace fix still missing (tracker auto-expired) + new daily-firewall-report secret-redaction cra #63348) was filed
  the same day by Workflow Health Manager, re-stating the same 3 items plus 2 new findings
  (daily-fact re-open, daily-firewall-report crash).
• Diagnosed and reported, as a new finding, the systemic diagnose-but-never-convert-to-PR gap
  underlying the repeated tracker self-expiry — distinct from (and a root cause of) the metrics
  staleness that has blocked full agent scoring for 14 consecutive runs.
• Deferred full agent quality/effectiveness ranking again this run — publishing scores from a
  24-day-stale snapshot would be misleading; this decision is unchanged from the prior 13 runs.
• Created this weekly performance report discussion.

Next Steps

1. Land a PR applying the 3 single-line diffs specified in [Workflow Health] 3 root-caused workflow failures: avenger npm-symlink, metrics-collector missing model-provider, gpclean retire #63098/[Workflow Health] daily-fact mempalace fix still missing (tracker auto-expired) + new daily-firewall-report secret-redaction cra #63348 (avenger, metrics-collector,
   gpclean).
2. Once Metrics Collector produces a fresh snapshot, resume full per-agent quality/effectiveness
   scoring across the ~300-workflow roster — this is the single highest-priority backlog item for
   this workflow's own mandate.
3. Evaluate whether workflow-health-manager.md's expires: 1d should be relaxed for
   priority-p1/priority-p0 issues that already contain an applicable diff, to stop the
   self-expiry-without-fix cycle.
4. Re-audit the three named redesign-vs-deprecation candidates (Matt Pocock Skills Reviewer,
   Impeccable Skills Reviewer, Design Decision Gate) once activation data is available again.
