Core Mental Model
Skills Are Portable Agent Instructions
A skill is a directory containing a SKILL.md file (and optionally references/ and scripts/). The SKILL.md is a markdown document with YAML frontmatter that teaches an agent how to perform a specific task or work with a specific tool.
Skills are agent-agnostic by design. The same skill can be installed for Claude Code, Cursor, Windsurf, Copilot, and 40+ other AI agents. Each agent has its own installation path, but the skill content is shared.
