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
