@agents/PROMPT-DEFENSE.md # Agent Self-Evaluation Score your own output (or another agent's output) across four axes to identify quality gaps and feed improvements into the learning system. ## When to Use - After completing a `/team:*` pipeline run - After generating a deliverable (PRD, architecture doc, code review) - When user asks "how did I do?" or "evaluate this output" - Automatically at end of `/gsd-execute-phase` for quality tracking ## Evaluation Axes | Axis | Question | Failure Signals | |------|----------|-----------------| | **Correctness** | Is the output factually accurate and technically sound? | Wrong APIs, broken references, hallucinated facts, logic errors | | **Clarity** | Is the explanation understandable and well-structured? | Confusing structure, undefined jargon, missing context, rambling | | **Actionability** | Can the user act on the output immediately? | Vague suggestions, missing steps, no verification path | | **Conciseness** | Did it use the minimum tokens needed? | Redundancy, over-explanation, filler content, restating the question | ## Scoring Scale ``` 5 — Exceptional: no reasonable improvement possible 4 — Good: minor nits only, no substantive gaps 3 — Adequate: meets request but has notable weakness on ≥1 axis 2 — Weak: clear gap affecting usability or correctness 1 — Poor: fundamentally misses request or contains significant errors ``` ## The Evidence Rule Every score below 5 MUST cite specific evidence. A score of 3 cannot just say "could be better" — it must say exactly what is missing or wrong. **"Show the gap, don't just name it."** ## Procedure ### Step 1: Collect Raw Material Gather: - Original user request - Final output/deliverable - Tool outputs verifying correctness (test results, exit codes, lint) - User feedback received during task (corrections, "try again") ### Step 2: Score Each Axis Independently Rate 1-5 with mandatory evidence for scores <5. ### Step 3: Generate Eval Report ``` SELF-EVALUATION REPORT ====================== Task: {brief description} Overall: {weighted average}/5 CORRECTNESS: {score}/5 Evidence: {specific finding or "No issues found"} CLARITY: {score}/5 Evidence: {specific finding or "No issues found"} ACTIONABILITY: {score}/5 Evidence: {specific finding or "No issues found"} CONCISENESS: {score}/5 Evidence: {specific finding or "No issues found"} IMPROVEMENT INSTINCTS: - {trigger} → {action} (confidence: {0.3-0.9}) ``` ### Step 4: Feed Learning System If learning system is active (PR-27+), auto-generate instinct YAML from findings: ```yaml --- id: eval-{task-slug}-{axis-lowercase} trigger: "when {task type}" action: "{specific improvement}" confidence: 0.6 domain: quality source: self-eval scope: project --- ``` ## Integration Points - `/team:verify` invokes self-eval on Layer 2 output before Layer 3 review - `/gsd-execute-phase` runs self-eval per subagent, aggregates in SUMMARY.md - High-confidence eval instincts (≥0.8) auto-update team-toolkit.md quality notes - Low scores (≤2) on correctness trigger automatic re-execution offer
