Guides Claude Code through planning, TDD, debugging, code review, and subagent-driven software development.
The directory
Claude Code plugins
A plugin is a bundle of skills, commands, agents, hooks and MCP servers that Claude Code installs as one unit from a marketplace with /plugin install. Each listing says what the plugin adds, where it comes from and the command that installs it. Skills on their own are listed separately in the skills directory.
