Agent engineering platform for building LLM applications from composable parts
Curated index of 1,000+ production-ready Claude Skills and agent plugins
Best for: anyone extending Claude Code, Codex, Cursor or a similar coding agent who would rather adapt an existing skill than write one from scratch.
Awesome Claude Skills is a curated index maintained by ComposioHQ that catalogues over a thousand production-ready Claude Skills and plugins. Skills are reusable instruction bundles that teach an agent how to perform a specific task, and this list organises them by use case so you can find one and adapt it rather than starting from a blank file.
What makes it useful: coverage extends well beyond Claude itself. The listed skills are documented as working across Claude.ai, Claude Code, Codex, Cursor, Gemini CLI and Antigravity, so the effort you spend learning the format transfers between harnesses.
Where it falls short: it is a link directory, not software, so quality varies by entry and you should read any skill before running it. The repository carries no declared license, which matters if you plan to redistribute its contents. It is also maintained by Composio and promotes their MCP Gateway alongside the community entries, so read the recommendations with that in mind.
Details: Python tooling. No declared license.
