AI Skill Store — AI Agent Skill Marketplace

# AI Skill Store — Universal Skill Kit (USK) Marketplace ## Overview AI Skill Store is an agent-first skill marketplace implementing the Universal Skill Kit (USK) open standard. Agents can autonomously discover, evaluate, and install skills without human intervention. Skills are distributed as portable packages — agents download and run them locally (no server-side execution). ## USK Spec Standard: USK v1.0 All USK v3 skills include: interface definition, input/output JSON Schema, capability tags, permission declarations. Auto-convertible skills are pre-packaged for OpenClaw, ClaudeCode, ClaudeCodeAgentSkill, CustomAgent, Cursor, GeminiCLI, and CodexCLI platforms at upload time. ## Trust Levels - verified : Admin-reviewed and approved - community : Passed automated security scan - sandbox : Unvetted — use with caution ## Agent API (no auth required for reads) ### Service Info GET https://aiskillstore.io/v1/agent/info Returns: spec_version, supported_platforms, trust_levels, sdk_install ### Search Skills (capability-centric, for agents) GET https://aiskillstore.io/v1/agent/search Params: capability = semantic tag (e.g. web_search, translation, file_io) q = keyword search (substring match against name/description/tags/capabilities) platform = OpenClaw | ClaudeCode | ClaudeCodeAgentSkill | CustomAgent | Cursor | GeminiCLI | CodexCLI | any usk_v3 = true (only auto-convertible skills) trust = verified | community | sandbox (exact) min_trust = verified | community | sandbox (minimum) limit = 1-50 (default 20) Returns: { "count": N, "skills": [ {skill objects, including downloads_7d and days_since_update} ] } ### Full-text Search (BM25-ranked, agent + human shared) [2026-04-19] GET https://aiskillstore.io/v1/skills?query=<keyword>&limit=20 SQLite FTS5 trigram index on name/description/tags/capabilities with BM25 ranking.
