Performance Rankings

Top Performing Agents 🏆

1. spec-enforcer (Quality: 85/100, Effectiveness: 88/100)

   • 100% merge rate, consistent targeted output
   • Single focused task per run, no over-creation
   • Example: [spec-enforcer] Enforce specifications for typeutil, workflow, actionpins #35910

2. copilot-swe-agent (Quality: 84/100, Effectiveness: 82/100)

   • 36 PRs merged in 7 days (94% merge rate) — highest throughput in ecosystem
   • Diverse fix types: Claude tools, MCP lifecycle, step naming, linter additions
   • Pattern: ⚠️ high volume (warn) — quality remains strong but pace warrants monitoring
   • Examples: Clarify Outcome Collector reference mapping to enforce exact Status-order link parity #35852, Add missing Claude Opus multiplier aliases and correct GPT-5.5 multipliers for 2026-05-30 inventory #35826, DDUw: catch not_planned docs-coverage/convention gaps (engine-example parity) #35820, Refactor Agentic Workflows routing: move dispatch index to skill, keep agent static, and update init generator #35817, refactor(workflow): decompose Claude allowed-tools assembly to reduce function complexity #35812, Fix context cancel lifecycle violations in workflow + MCP inspect paths #35811

3. docs-updater (Quality: 78/100, Effectiveness: 72/100)

   • Consistent daily cadence, 70% merge rate
   • Well-structured PRs with clear descriptions
   • Examples: [docs] Update documentation for features from 2026-05-30 #35906, [log] Add debug logging to three previously-unlogged pkg/ files #35857, [docs] docs: apply American English spelling in content reference docs #35853

4. ab-advisor (Quality: 72/100, Effectiveness: 65/100)

   • Reasonable campaign and issue quality
   • Experimental agent showing good early indicators

5. deep-report (Quality: 68/100, Effectiveness: 62/100)

   • Detailed, well-structured reports
   • Moderate effectiveness for report-generation class

Agents Needing Improvement 📉

1. daily-safe-output-optimizer (Quality: 40/100, Effectiveness: 20/100) 🔴

   • Runaway loop: 115 turns, 14.9M tokens consumed
   • Tracked: [aw] Daily Safe Output Tool Optimizer failed #35316 — must not run until loop-termination guards added
   • Recommendation: Hard turn limit (max 10), explicit completion criteria in prompt

2. failure-reporters (Quality: 55/100, Effectiveness: 45/100) 🔴

   • 20 issues/day, 60% duplicate rate = ~12 duplicates daily
   • 4th consecutive escalation — no dedup gate implemented
   • Recommendation: Add "check for existing open issue with same title" before creation

3. chaos-test (Quality: 70/100, Effectiveness: 60/100) 🔴

   • 5 open PRs, 0 merged in 7d — batch-creation stall
   • Over-creating PRs that land in an unreviewed queue
   • Recommendation: Limit to 2 PRs per run, add review gate before next batch

4. lint-monster (Quality: 55/100, Effectiveness: 40/100) 🔴

   • 2,218-issue backlog with 50% timeout rate
   • Resource exhaustion cycle: creates faster than pipeline can process
   • Recommendation: Rate limit to 10 new issues/run, implement backlog drain check

5. step-name-alignment (Quality: 30/100, Effectiveness: 20/100) 🔴

   • 80% failure rate since May 20 — 10+ days of degradation
   • Structural regression, not transient
   • Blocked on P1 fix (filed 2026-05-29 by Workflow Health Manager)

Blocked Agents (Infrastructure) 🚫

• smoke-tests: 100% failure all variants — tracked in [aw] Smoke Copilot failed #35829, [aw] Smoke Codex failed #35832, Smoke Test: Copilot - 26674439192 #35856+
• copilot-cli-workflows: 0% since May 28 — tracked in [aw] Copilot CLI Deep Research Agent failed #35388
• pr-sous-chef: 0% — blocked by [aw-failures] Failure Investigator (6h) — 4 failures, safe_outputs add_comment validation breaks 3 workflows (2026-05-27 19:24 → 2026-05-28 01 [Content truncated due to length] #35351 (partial fix in PR fix: safe output handlers now respect target-repo config #35901)
• agentic-commands: 25% success (down from 80%) — CJS correlation

Infrastructure Outage Cluster

smoke-tests, copilot-cli-workflows, and pr-sous-chef are all blocked by distinct but potentially related platform issues (#35351, #35388). May share a common root cause in the May 20–28 infrastructure window.

Runaway Resource Cluster

daily-safe-output-optimizer (14.9M tokens, 115 turns) and lint-monster (2,218 backlog, 50% timeouts) represent two failure modes of the same root problem: no upper-bound guards on iteration or output volume.

Regression Cluster

step-name-alignment (degraded since May 20) and agentic-commands (CJS regression) both trace to changes in the May 20–28 window. A platform/dependency change in this window has not been fully diagnosed.

Coverage & Ecosystem Health

Well-Covered Areas ✅

• Code quality automation (spec-enforcer, lint-monster, code-simplifier)
• Documentation maintenance (docs-updater, docs-reviewer)
• Agent/PR development (copilot-swe-agent — dominant contributor)
• Experimentation (ab-advisor, chaos-test)
• Failure detection (failure-reporters, workflow-health-manager)

Coverage Gaps ⚠️

• Smoke test recovery: current smoke infrastructure failure leaves the ecosystem without validation signals
• Dedup infrastructure: no shared deduplication layer — each agent implements (or doesn't) its own
• Token/turn budget enforcement: no platform-level guard against runaway loops

Redundancy

• Multiple agents monitoring overlapping health metrics (could share state via shared-alerts.md more actively)
• failure-reporters + [aw] issue creation — two channels for the same signal class

---

Recommendations

High Priority 🔴

1. Verify P0 [aw-failures] Failure Investigator (6h) — 4 failures, safe_outputs add_comment validation breaks 3 workflows (2026-05-27 19:24 → 2026-05-28 01 [Content truncated due to length] #35351 resolution after PR fix: safe output handlers now respect target-repo config #35901 merge

   • Check if item_number validation issue is also covered
   • If resolved, unblock PR Sous Chef and Contribution Check campaigns
   • Expected: unblocks 3+ blocked workflows

2. Add dedup gate to failure-reporters (4th escalation)

   • Search for open issue with matching title before creating
   • Eliminates ~12 duplicate issues/day
   • Estimated effort: 1–2 hours

3. Halt daily-safe-output-optimizer until loop guards added ([aw] Daily Safe Output Tool Optimizer failed #35316)

   • Add max_turns: 10 and explicit completion signal to prompt
   • Current cost: 14.9M tokens per run with poor results

4. Rate-limit lint-monster to 10 issues/run

   • Add backlog size check: skip creation if >500 open LintMonster issues
   • Prevents resource exhaustion cycle

Medium Priority ⚠️

5. Chaos-test PR accumulation: cap to 2 PRs/run, add review gate
6. Agentic Commands + Step Name Alignment: coordinate rollback/fix with CJS changes
7. Copilot CLI engine fix ([aw] Copilot CLI Deep Research Agent failed #35388): required before re-enabling jsweep, Documentation Noob Tester, Copilot CLI Deep Research Agent

Watch List 👀

• copilot-swe-agent volume: 36 merges/7d is healthy now but monitor for quality drift at this pace
• CGO CI: new unit test failures may indicate broader build instability

---

Trends

• Overall agent quality: 71/100 (↓3 from last week)
• Average effectiveness: 66/100 (↓6 from last week)
