Skill Creator is an Agent Skill for building, modifying, and improving other Agent Skills, and for measuring how well they perform. Use it to author a skill from scratch, edit or optimize an existing one, run evals to test a skill, or benchmark its performance with variance analysis. It also helps optimize a skill's description so it triggers more accurately when relevant.
