Claude Code Skills and Plugins as an Open Source Project

180+ production-ready skills and plugins for Claude Code, OpenAI Codex, Gemini CLI, and OpenClaw — reusable expertise bundles that transform AI coding agents into specialized professionals across engineering, product, marketing, compliance, and more.

Skills are modular instruction packages (plugins) that give AI coding agents domain expertise they don't have out of the box. Each skill includes a SKILL.md (instructions + workflows), Python CLI tools, and reference documentation — everything the agent needs to perform like a specialist.

One repo, four platforms: Works natively as Claude Code plugins, OpenAI Codex CLI and agents, Gemini CLI skills, and OpenClaw skills. All 237 Python tools are stdlib-only and verified working.
