Skills
Claude Agent Skills — drop-in capabilities that teach Claude a specialized job and load only when they're relevant. Filter by category or license, then open any skill for what it does and how to install it.
How skills work
A skill is a folder with a SKILL.md (plus any scripts or templates). Claude reads the descriptions, then loads a skill only when your request matches it — so dozens can sit installed without bloating context.
1 · Get it
Anthropic’s document skills are built in. Community skills are a folder you download.
2 · Install
Drop the folder in ~/.claude/skills/ (personal) or .claude/skills/ (per project).
3 · Use it
Just ask in plain language — Claude activates the skill automatically when relevant.
