Claude Code Plugins Marketplace

A curated collection of Claude Code-compatible plugins for various development workflows. Each plugin extends agent capabilities with custom slash commands, MCP servers, skills, and agents.

The marketplace uses Claude Code's plugin packaging contracts (.claude-plugin, CLAUDE_PLUGIN_ROOT, plugin install commands), but agent-facing instructions are kept neutral so compatible hosts such as Codex can consume the same skills and prompts where supported.
