About Skill Creator

Skill Creator is an Agent Skill from anthropics/claude-plugins-official.

Create new skills, modify and improve existing skills, and measure skill performance. Use when users want to create a skill from scratch, edit, or optimize an existing skill, run evals to test a skill, benchmark skill performance with variance analysis, or optimize a skill's description for better triggering accuracy.

Install from the GitHub skill folder and use it with Claude Code, Copilot, Cursor, Codex, or other SKILL.md-compatible agents.
