Agent Performance Report - Week of 2026-09-10

[github-actions[bot]]

Executive Summary

• Data source: metrics/latest.json remains dated 2026-09-01 (10 days stale). Root cause confirmed live this run: Metrics Collector's own workflow is currently broken — issue [aw] Metrics Collector produced no safe outputs #59851 "[aw] Metrics Collector produced no safe outputs" is open (created 2026-09-10T02:45Z), following a string of prior recurrences ([aw] Metrics Collector produced no safe outputs #59611, [aw] Metrics Collector produced no safe outputs #59344, [aw] Metrics Collector produced no safe outputs #59105, [aw] Metrics Collector timed out #58701, [aw] Metrics Collector timed out #58367, [aw] Failed jobs: Metrics Collector #58133, [aw] Failed jobs: Metrics Collector #57830, plus data-quality issue [deep-report] metrics-collector: stale snapshot (4+ days) and AR-vs-executed count bug for cgo/content-moderation #58848 on an AR-vs-executed counting bug). This is now a chronic, unresolved systemic issue, not a one-off — it has recurred at least 9 times since inception and nobody has landed a durable fix.
• Full ecosystem ranking against the 41 "active" workflows in the stale snapshot would misrepresent current reality (compare 41 active on 2026-09-01 vs. 247 on 2026-08-22 — an 83% single-day swing the collector itself attributed to an API-fallback truncation bug). Per prior-run guidance, I deferred a full ranking again and instead spot-verified the specific items shared memory flagged as open concerns, using live GitHub reads (which worked cleanly this session — no MCP filtering issue recurred).
• Top verified finding: lint-monster and daily-go-test-parallelizer have both recovered, contradicting the standing "unresolved model misconfiguration" root cause carried in shared-alerts.md/workflow-health-latest.md since 2026-09-09/10.

Verification: lint-monster / daily-go-test-parallelizer model config claim

Shared alerts assert the recurring model_not_supported_error on lint-monster (model: openai/gpt-5.3-codex) and daily-go-test-parallelizer (model: copilot/gpt-5.3-codex) is a permanent config defect requiring a model:/model-provider change. I re-verified against pkg/cli/data/models.json and live run history:

• gpt-5.3-codex is a valid, listed model for both the openai and github-copilot providers in pkg/cli/data/models.json — the model name itself is not invalid.
• Live run history (actions_list.list_workflow_runs) for daily-go-test-parallelizer: last 10/10 runs succeeded (2026-09-09T18:35Z → 2026-09-10T12:41Z), same model: config throughout.
• Live run history for lint-monster: last run (2026-09-10T02:37Z) succeeded; of the 3 prior scheduled runs 2 failed (09-06, 09-08) and 1 succeeded (09-05/09-07 pattern), same model: config throughout, no code change to the workflow file since.

Correction to shared alerts: the failures are more consistent with an intermittent model-availability/policy blip (matches the error message's own "may be disabled by Copilot policy" hint) than a hard misconfiguration — the identical config now succeeds reliably. Recommend downgrading this from "needs a model:/model-provider fix" to "monitor; do not change working config based on transient policy flakiness." Do not re-file — #59853/#59879/#59847 already track the occurrences; closed #59790 correctly self-resolved.

Metrics Collector — chronic failure, now the top systemic blocker

• Currently open: [aw] Metrics Collector produced no safe outputs #59851 (created 2026-09-10T02:45Z, still open).
• Historical recurrence count (search "Metrics Collector" produced no safe outputs|timed out|Failed jobs): 9 distinct issues since inception ([aw] Metrics Collector produced no safe outputs #59851, [aw] Metrics Collector produced no safe outputs #59611, [aw] Metrics Collector produced no safe outputs #59344, [aw] Metrics Collector produced no safe outputs #59105, [deep-report] metrics-collector: stale snapshot (4+ days) and AR-vs-executed count bug for cgo/content-moderation #58848, [aw] Metrics Collector timed out #58701, [aw] Metrics Collector timed out #58367, [aw] Failed jobs: Metrics Collector #58133, [aw] Failed jobs: Metrics Collector #57830), spanning at least 3 weeks with no durable fix landing.
• Impact: every downstream orchestrator (Agent Performance Analyzer, Workflow Health Manager, Campaign Manager) is now operating on a metrics snapshot that is structurally unreliable — the ecosystem has effectively had no fresh ranking-quality data since 2026-09-01. This is the single highest-leverage fix available: stabilizing Metrics Collector unblocks accurate scoring for all three meta-orchestrators simultaneously.
• Recommend: treat as P0. The recurring pattern (produces no safe outputs / times out) suggests a timeout or log-pagination bug in the collector's own workflow, not model config (per prior [agent-performance] Metrics Collector safe-output/engagement fields zeroed by recurring log-tool timeout (2 consecutive days) #50560 note on "log-tool timeout"). Needs an actual engineering fix (raise timeout, paginate more robustly, or reduce collection scope), not another auto-filed/auto-expired issue cycle.

Behavioral Patterns (from stale-but-available profile data)

• agentic_commands / Q-style command-gated workflows: 13/19 runs show action_required — this matches the documented "command gating (expected)" design (slash-command workflows start a run per event, then the activation gate stops non-matching ones). Not a defect; excluded from failure scoring.
• cjs: 4 executed runs, 1 failure, 2 AR in the stale snapshot — but this is a plain CI workflow (.github/workflows/cjs.yml), not an agentic .md workflow, consistent with WHM's prior classification. No agentic action needed.
• pr-sous-chef: highest safe-output volume in the active set (5: 1 issue + 4 comments, 3/3 executed runs successful) — best-performing agent with real output in this stale window.

Coverage / Data-Quality Gap

• Cannot compute meaningful quality/effectiveness scores, PR merge rates, or full agent rankings this run — the underlying daily metrics history is stale at the source, and re-deriving 30 days of scores from raw GitHub queries under this run's token budget isn't feasible. This gap has now persisted for 2 consecutive analyzer runs (09-09, 09-10).

Recommendations

High Priority

1. Fix Metrics Collector's recurring failure (P0, new escalation this run) — 9 recurrences and 10 days of stale data is no longer a "monitor" item; needs a maintainer to land a durable fix (timeout/pagination), not rely on auto-expiring issues. Expected impact: restores ranking-quality data for all 3 meta-orchestrators.
2. Correct the lint-monster/daily-go-test-parallelizer root-cause note in shared memory — replace "misconfigured model, needs a fix" with "transient policy/availability flakiness, config confirmed valid, monitor only." Prevents a future run from prescribing an unnecessary (and possibly harmful) model change to a config that is now working 10/10.

Medium Priority

3. Once Metrics Collector is stable for 3+ consecutive clean days, re-run full agent ranking (carried over recommendation, now overdue two runs).

Trends

• Data freshness: 10 days stale (↓ from 9 days last run) — regressing, not improving.
• Metrics Collector reliability: 9 cumulative failure issues — new escalation, not previously quantified in shared memory.
• lint-monster / daily-go-test-parallelizer: recovered (10/10 and mostly-clean recent runs) — root cause reclassified from config defect to transient flakiness.

Actions Taken This Run

• Verified GitHub MCP read access is working cleanly this session (prior session-specific filtering issue did not recur — no new issue needed, consistent with "retest before escalating" from last run).
• Re-verified and corrected the standing "misconfigured model" root cause for lint-monster/daily-go-test-parallelizer against live run history and pkg/cli/data/models.json.
• Escalated Metrics Collector's chronic failure pattern (9 recurrences) as the top P0 systemic blocker.
• Updated agent-performance-latest.md and shared-alerts.md in repo memory with these corrections.
• No new GitHub issues filed — the Metrics Collector failure is already tracked by open [aw] Metrics Collector produced no safe outputs #59851; re-filing would violate DO-NOT-RE-FILE guidance. Escalation is via this report + shared-alerts note instead.

Next Steps

1. Track whether [aw] Metrics Collector produced no safe outputs #59851 (or a successor) gets a real fix vs. auto-expiring again.
2. Re-run full agent ranking once metrics/latest.json is fresh (≤2 days old) for 3+ consecutive collector runs.
3. Confirm the lint-monster/daily-go-test-parallelizer correction propagates and isn't re-flagged as a config defect without new evidence.
