agent-self-eval

Post-run self-evaluation system that scores agent output on correctness, clarity, actionability, and conciseness. Use after /team runs, skill executions, or when explicitly asked to evaluate output qu

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:

---
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
