Plugin

One installable package that adds commands, skills, and helpers to Claude Code at once, like an app bundle.

Definition

A Claude Code package that bundles commands, agents, skills, hooks, and MCP servers behind one manifest (.claude-plugin/plugin.json), installable from a plugin marketplace.

Example
