What Are Agent Skills?

Skills are markdown instruction files that extend AI coding agents' capabilities. Each skill is a SKILL.md file that teaches agents new behaviors, workflows, and domain expertise. They work with Claude Code, Cursor, Windsurf, and other agents that support the skills convention.

Development

The extension is vanilla JS with zero dependencies. No build step required.
