# Skill Evaluator
Audit a target skill to see whether its instructions actually land when Claude runs it. This skill does NOT benchmark skill-vs-no-skill (that's `skill-creator`'s job). This skill checks rule adherence under realistic prompts, classifies where failures come from, and proposes targeted fixes.
## Scope
**Good fit — v1 supports:**
- Workflow skills (sequences of steps, shutdown rituals, review passes)
- Rule-shaped skills (policies, conventions, constraints, checklists)
- Guideline skills (style guides, voice guides, design rules)
**Out of scope for v1 (say so explicitly if asked):**
- Creative-synthesis skills (brand voice, canvas design, algorithmic art) — rule-adherence framing does not apply cleanly to "is this output beautiful"
- Skills whose value is measured by end-user outcomes over time (engagement, retention)
If the user asks to evaluate a creative-synthesis skill, say the harness is not validated for that skill type and ask if they want to proceed anyway with a best-effort run. Do not silently pretend it works.
## Differentiation from skill-creator
| skill-creator | skill-evaluator |
|--|--|
| Authors new skills | Audits existing skills |
| Benchmarks skill-vs-baseline (A/B) | Measures rule adherence under realistic prompts |
| Asks "does the skill help?" | Asks "does the skill's text actually land?" |
| Outputs: a skill | Outputs: findings + rule-text diffs |
You can chain them: evaluator finds a gap → creator's conventions guide the rule-t
