What it does

Guides an author through interviewing the user, drafting SKILL.md content, creating test cases, running with-skill and baseline evaluations, grading results, and producing a reviewer report and benchmark. Also includes tools for iterating on descriptions to improve triggering accuracy.

When to use it

Use this skill when you need to create a new Agent Skill from a user conversation, improve an existing SKILL.md, run repeatable evals and benchmarks, or optimize a skill's frontmatter and triggers for better activation. Useful when you want structured test cases, reproducible grading, and an HTML reviewer for human feedback.
