claude-plugins-official is Anthropic's managed, curated marketplace of Claude Code plugins, split into a /plugins area for plugins built by Anthropic and an /external_plugins area for vetted partner and community submissions. A plugin bundles a required plugin.json manifest plus optional slash commands, agent definitions, skill definitions, and MCP server configuration. Install entries with /plugin install or browse via /plugin > Discover; note Anthropic cannot fully control or verify third-party plugin contents, so only install ones you trust.
