add-skill

Add an external skill from a GitHub repository to the current workspace. Use this when users want to import, install, or add a skill from a GitHub URL (for example: /add-skill https://github.com/OpenHands/extensions/tree/main/skills/codereview or 'add the codereview skill from https://github.com/OpenHands/extensions/'). The command fetches the skill files and places them in .agents/skills/.
