Agent Skills
Packaged know-how the AI loads only when a task needs it, like a recipe card pulled from a box.
Definition
Reusable packages of domain expertise defined in SKILL.md files that provide specialized capabilities, knowledge, and refined workflows to AI agents. Skills can be scoped to specific domains like testing strategies, API design, or performance optimization, and can be invoked as slash commands or loaded automatically by the model.
Example
A .claude/skills/release/SKILL.md describing release steps loads only when you ask to ship, keeping it out of unrelated sessions.
