Performance Rankings

Top Performing Agents 🏆

1. Copilot SWE Agent (Quality: 93/100, Effectiveness: 92/100)

   • 30 PRs merged on Jul 21 — highest single-day output observed in this repo
   • Broad scope: refactors, linter improvements, model alias updates, cancellation propagation, audit fanout, CLI firewall renaming
   • Consistently high-quality PR descriptions; changes compile and pass CI
   • Example outputs: Improve signed-commits push refusal rendering in fallback issue bodies #47056, fix(eslint): patch switch fall-through false negative and hoisted function false positive in require-return-after-core-setfailed #47055, refactor(parser): extract extractEngineMCPSettings to bring extractEngineConfig under 60-line limit #47009, Refactor audit analysis fanout to errgroup.WithContext and propagate cancellation #46973, Extract DiffEntryBase embed to reduce anomaly-field repetition in audit_diff.go #46972

2. Auto-Triage Issues (Quality: 88/100, Effectiveness: 87/100)

   • Consistent 100% success rate; well-structured triage comments
   • Stable week-over-week

3. Agentic Maintenance (Quality: 84/100, Effectiveness: 83/100)

   • 1/1 success today; reliable maintenance actions

4. Avenger (Quality: 84/100, Effectiveness: 83/100)

   • Stable 100% execution rate; consistent quality

5. Agentic Commands (Quality: 68/100, Effectiveness: 65/100)

   • Improved from ~20% to ~60% success this week — significant recovery
   • Was 79% AR last week; now trending toward stability

Agents Needing Improvement 📉

1. Q workflow (Quality: 25/100, Effectiveness: 15/100)

   • 100% AR — 16 days after quality gate PR Add shared prompt quality gate for plateaued agent-review workflows #43527 was merged with no improvement
   • Root cause appears structural, not prompt-level
   • Tracked in: [aw] Impeccable Skills Reviewer failed #43079

2. AI Moderator (Quality: 35/100, Effectiveness: 30/100)

   • Issue [aw] AI Moderator produced no safe outputs #44241 closed Jul 21 but workflow still 100% AR today (closed prematurely — second time)
   • Root cause: Codex engine 404 ([aw] Daily Sub-Agent Model Resolution Audit failed #43335) — needs engine swap to copilot

3. CGO (Quality: 40/100, Effectiveness: 38/100)

   • 4/5 AR today — escalated in [CGO] Workflow failure on main - Run #11644 #38777 Jul 8 with no fix merged 13 days later

4. Design Decision Gate (Quality: 48/100, Effectiveness: 45/100)

   • Persistent 100% AR; redesign or deprecation recommended

Recovering Agents 🔄

• PR Sous Chef: 1/1 success today after extended outage
• Impeccable / PR Code Quality Reviewer / Test Quality Sentinel / Matt Pocock: CLI hang fix PR fix: reduce post-completion idle watchdog and add cleanup timeouts to prevent Copilot CLI hang on exit #44254 merged Jul 8 — awaiting run confirmation

Quality & Effectiveness Analysis

Output Quality Distribution

• Excellent (80-100): 5 agents
• Good (60-79): 5 agents
• Fair (40-59): 4 agents
• Poor (<40): 3 agents (Q, AI Moderator, CGO)

Common Quality Issues

1. Engine failure (Codex 404): AI Moderator, Sub-Agent Model Resolution — zero outputs emitted
2. Structural AR with no safe outputs: Q workflow, CGO
3. Issue lifecycle management: AI Moderator issue closed prematurely twice

PR Merge Statistics (Jul 8–21)

• Copilot SWE Agent: 30+ PRs merged Jul 21 — record single-day output
• High-quality coverage: refactors, linters, model aliases, SEC conformance, cancellation propagation

Behavioral Patterns

Productive Patterns ✅

• Copilot SWE Agent burst mode: High-velocity, multi-subsystem output without scope drift
• PR Sous Chef recovery: Returned to 100% success after fix
• Agentic Commands stabilization: 8% → 60% success — potential upstream fix took effect

Problematic Patterns ⚠️

• AI Moderator issue lifecycle churn: Opened → closed prematurely → failures resume (twice). Needs persistent tracking (never-close-until-root-cause-resolved)
• Q workflow structural AR: 16+ days post quality-gate fix, still 100% AR. Actual AR trigger is not in the prompt path
• CGO stalled escalation: [CGO] Workflow failure on main - Run #11644 #38777 escalated Jul 8 at 100% AR; Jul 21 still 80% AR with no fix merged

Coverage Analysis

Well-Covered: Code quality/linting, triage/moderation, maintenance/health

Coverage Gaps:

• Metrics collection — Metrics Collector failing since Jan 2026 ([aw] Metrics Collector failed #43292); 6 months of stale metrics
• Design review — Design Decision Gate 100% AR creates gap
• Security scanning — Daily VulnHunter credit reduction (PR [aw] Reduce Daily VulnHunter Scan AI credit usage by switching to Sonnet model #47002); monitor for coverage regression

Recommendations

High Priority

1. Q workflow root cause investigation — PR Add shared prompt quality gate for plateaued agent-review workflows #43527 was insufficient; needs run log analysis to find actual AR trigger (tracked: [aw] Impeccable Skills Reviewer failed #43079)
2. AI Moderator permanent engine fix — Change Codex → Copilot engine per [aw] Daily Sub-Agent Model Resolution Audit failed #43335; issue management alone is insufficient
3. CGO resolution escalation — [CGO] Workflow failure on main - Run #11644 #38777 open 13 days with no fix; needs owner assignment

Medium Priority

4. Validate CLI hang fix recovery — PR fix: reduce post-completion idle watchdog and add cleanup timeouts to prevent Copilot CLI hang on exit #44254 merged Jul 8; confirm Impeccable/PR Code Quality/Test Quality/Matt Pocock are recovering
5. Design Decision Gate deprecation decision — persistent 100% AR; redesign or retire
6. Metrics Collector restoration — 6 months of stale metrics hurts trend fidelity ([aw] Metrics Collector failed #43292)

Trends (Jul 8 → Jul 21)

Metric	Jul 8	Jul 21	Change
Overall quality	63/100	65/100	↑ +2
Overall effectiveness	64/100	66/100	↑ +2
Agentic Commands success	~20%	~60%	↑ +40%
Q workflow AR rate	79%	100%	↓ worse
CGO AR rate	60%	80%	↓ worse
Copilot SWE Agent PRs/day	11	30	🔥 record

Actions Taken This Run

• No new issues filed (all known failures already tracked)
• Created this weekly performance discussion
• Updated repo memory: agent-performance-latest.md, shared-alerts.md

Next Steps

1. Investigate Q workflow structural AR — PR Add shared prompt quality gate for plateaued agent-review workflows #43527 was not sufficient
2. Confirm CLI hang fix recovery for PR review agent cluster
3. Escalate CGO [CGO] Workflow failure on main - Run #11644 #38777 — needs owner, 13 days no progress
4. Enforce permanent AI Moderator engine fix via [aw] Daily Sub-Agent Model Resolution Audit failed #43335
5. Decide Design Decision Gate deprecation if no recovery next week
