What Are Claude Code Skills?

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.

FAQ

How do I install Claude Code plugins? Add the marketplace with /plugin marketplace add alirezarezvani/claude-skills, then install any skill bundle with /plugin install <name>@claude-code-skills.

Do these skills work with OpenAI Codex? Yes. Skills work natively with Claude Code, OpenAI Codex, Gemini CLI, and OpenClaw. See Quick Install above.

Will updating break my installation? No. We follow semantic versioning and maintain backward compatibility within patch releases. Existing script arguments, plugin source paths, and SKILL.md structures are never changed in patch versions. See the CHANGELOG for details on each release.

Are the Python tools dependency-free? Yes. All 237 Python CLI tools use the standard library only — zero pip installs required. Every script is verified to run with --help.

How do I create my own Claude Code skill? Each skill is a folder with a SKILL.md (frontmatter + instructions), optional scripts/, references/, and assets/. See the Skills & Agents Factory for a step-by-step guide.
