SkillX.sh
An AI agent skills marketplace combining a web catalog, a semantic and keyword search engine, and a CLI, so an agent can find and run a matching skill for a task.
SkillX is a marketplace for AI agent skills, combining a web interface, a command-line tool, and a hybrid search engine. The web marketplace lets users browse skills with ratings, reviews, and usage statistics, see a quality-based leaderboard, favorite skills for personalized search, and sign in with GitHub OAuth.
Its search combines semantic search through vector embeddings with SQLite full-text search, ranked with reciprocal rank fusion and boost scoring. The CLI can search for a skill by description, use a specific skill by name, search and use in one step, and report back whether execution succeeded and how long it took, feeding usage data back into the leaderboard. According to the project's own roadmap, the current phase covers the web marketplace, CLI, search, authentication, and ratings, with payment integration, a sandboxed execution mode, and an MCP server mode planned for later phases.
