In simple English
This repository holds official and community plugins for the Claude Code command-line tool. You can find extra commands, new skills, and server connections to add to your AI coding assistant. It costs nothing to browse, but you need to run Claude Code to use them. You should check that you trust each plugin author before installing anything on your machine.
What it is
An official, Anthropic-managed directory of high-quality plugins for Claude Code. It contains internal plugins made by Anthropic and external plugins contributed by the community.
What it is good for
Anyone using Claude Code who wants to add new skills, slash commands, or server integrations without writing them from scratch.
Summary (Key Points)from the README
Key features
- Two directories: `/plugins` holds plugins built and maintained by Anthropic, and `/external_plugins` holds third-party plugins from partners and the community.
- Standard layout: Each plugin needs a `.claude-plugin/plugin.json` manifest. `.mcp.json`, `commands/`, `agents/` and `skills/` are optional.
- Skill bundles without a manifest: A marketplace entry can declare `SKILL.md` skills directly, using `strict: false` and an explicit `skills` array.
- Nested skill paths: Skill paths can reach deeper than one level, for example `./libA/skill-1`, so a curated subset can span several library subdirectories.
- Namespaced skill names: Each skill is registered as `<plugin-name>:<skill-name>`.
- Stable slugs: A published plugin's `name` must not change. Renames are handled through a top-level `renames` map that migrates existing installs.
- Display labels: `displayName` changes how a plugin appears in the UI without affecting its slug.
- Reference implementation: `/plugins/example-plugin` shows how an internal plugin is built.
Ways to install
| Platform or method | What it needs | Effort |
|---|---|---|
| Command: `/plugin install {plugin-name}@claude-plugins-official` | Claude Code with its plugin system | Not stated in README |
| Browse: `/plugin > Discover` | Claude Code with its plugin system | Not stated in README |
Important
- Trust: Anthropic does not control the MCP servers, files or other software in plugins. It cannot verify that they work as intended or that they won't change, so check each plugin's homepage before installing or updating.
- Renames: Changing a published plugin's `name` breaks existing installs with a `plugin-not-found` error unless a `renames` entry is added.
- External approval: Third-party plugins must meet the marketplace's quality and security standards before approval.
- Licensing: The directory has no single license. Each plugin's own LICENSE file applies.
