Search, discover, and dynamically load skills from the ClawHub registry at skills.droyd.ai. Use when an agent needs a capability it doesn't have, wants to find tools for a specific task, or needs to browse trending/popular skills. Triggers include requests to find skills, search for tools, discover capabilities, load a skill dynamically, check what skills exist for a domain, or run a skill without installing it. Also use when the user asks about available OpenClaw/ClawHub skills, wants to explore skill categories, or needs to fetch and execute skill content on the fly.
