Claude Plugins Official (Copilot-Compatible Fork)

A curated directory of high-quality plugins for Claude Code, fixed for GitHub Copilot CLI compatibility.

⚠️ Important: Make sure you trust a plugin before installing, updating, or using it. Anthropic does not control what MCP servers, files, or other software are included in plugins and cannot verify that they will work as intended or that they won't change. See each plugin's homepage for more information.

🔧 Why This Fork?

The original anthropics/claude-plugins-official marketplace uses source: "git-subdir" which is not supported by the @github/copilot schema validation.

This fork fixes:

• ✅ 12 plugins converted from invalid git-subdir → valid github source format
• ✅ Renamed wordpress.com → wordpress-com (kebab-case requirement)

📦 Installation (GitHub Copilot CLI)

Add the marketplace:

copilot plugin marketplace add quochieudn2303/claude-plugins-official-copilot

Or via interactive mode:

/plugin marketplace add quochieudn2303/claude-plugins-official-copilot

Browse available plugins:

/plugin marketplace browse claude-plugins-official-copilot

Install a plugin:

/plugin install {plugin-name}@claude-plugins-official-copilot

Structure

• /plugins - Internal plugins developed and maintained by Anthropic
• /external_plugins - Third-party plugins from partners and the community

Installation (Claude Code)

For the original Claude Code, you may want to use the upstream repo instead:

/plugin install {plugin-name}@claude-plugins-official

or browse for the plugin in /plugin > Discover

Contributing

Internal Plugins

Internal plugins are developed by Anthropic team members. See /plugins/example-plugin for a reference implementation.

External Plugins

Third-party partners can submit plugins for inclusion in the marketplace. External plugins must meet quality and security standards for approval. To submit a new plugin, use the plugin directory submission form.
