Claude Code Skills Marketplace

A community-driven collection of custom skills for Claude Code, Anthropic's CLI tool for software engineering with Claude.

What are Skills?

Skills are reusable prompt templates that extend Claude Code's capabilities. They let you package expert instructions into shareable, versioned modules that anyone can install and invoke with a slash command.

Examples of what skills can do:

• Enforce project-specific code review checklists
• Generate boilerplate tailored to your stack
• Run multi-step workflows (test, lint, commit, deploy)
• Automate documentation generation
• Perform security audits with custom rulesets
