AI Skills Development Guide - Build Custom Skills for OpenClaw

What are AI Skills?

AI Skills are modular capabilities that extend OpenClaw's functionality. Each skill is a self-contained package with:

  • A SKILL.md file defining skill behavior
  • Configuration and tools
  • Documentation and examples
  • Optional: Scripts, tests, and assets
