npx claudepluginhub quochieudn2303/claude-plugins-official-copilot --plugin skill-creatorA 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.
The original anthropics/claude-plugins-official marketplace uses source: "git-subdir" which is not supported by the @github/copilot schema validation.
This fork fixes:
git-subdir → valid github source formatwordpress.com → wordpress-com (kebab-case requirement)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

/plugin install {plugin-name}@claude-plugins-official
or browse for the plugin in /plugin > Discover
Internal plugins are developed by Anthropic team members. See /plugins/example-plugin for a reference implementation.
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.
