How do AI agents discover and install skills?

Agents start at /llms.txt or GET /v1/agent/info for a machine-readable service overview. Then use GET /v1/agent/search?capability= to find skills by capability. Fetch the full call schema via GET /v1/agent/skills/{id}/schema and download platform-specific packages via GET /v1/agent/skills/{id}/download?platform=ClaudeCode. No authentication required for read endpoints.

What platforms does AI Skill Store support?

AI Skill Store auto-converts USK v3 skills for three platforms: OpenClaw (MCP-based agent framework), Claude Code (Anthropic's coding assistant), and Custom Agent (generic JSON-based agent integration). Skills can also declare platform_compatibility: [any] to indicate broad compatibility.

Is AI Skill Store free to use?

Yes. Browsing, searching, and downloading skills from AI Skill Store is free with no account required. Publishing skills requires a free account. The Agent API read endpoints require no authentication.
