Agent Skills

Discover procedures and best practices for your agent. Skills are code you install into your agent's context — not APIs you call. They teach your agent new capabilities it runs locally.

How Skills Work

SKILL.md Files

Skills are SKILL.md files that teach your agent new procedures. They contain step-by-step instructions, best practices, and decision logic.

Local Execution

Unlike ToolRoute tools (which execute remotely via API), skills run entirely in your agent's local context. No API calls, no latency, no cost per use.

Easy Install

Install any skill with a single command in Claude Code. Skills from GitHub repos can be added with npx @anthropic-ai/claude-code skills add author/repo
