Skill Creator

Create, evaluate, improve, package, and maintain Claude skills. Use this skill when the user wants a new skill, an existing skill changed, skill performance measured, evals run, or a skill description optimized for triggering accuracy.

Core Loop

1. Determine where the user is: new skill, draft review, eval run, improvement, description optimization, packaging, or troubleshooting.
2. Capture intent and confirm the required input contract before writing.
3. Draft or edit the skill folder.
4. Create realistic test prompts when testing is useful.
5. Run skill-vs-baseline evals when tooling supports it; otherwise run a smaller qualitative review.
6. Grade outputs, gather user feedback, and improve the skill.
7. Repeat until the user is satisfied, objective checks pass, or progress stalls.
8. Package or present the final skill when requested and supported.
