Anthropic has launched an official plugin marketplace for Claude Code, publishing a curated directory on GitHub that serves as the centralized hub for discovering and installing extensions.
The repository, anthropics/claude-plugins-official, separates plugins into two categories: internal plugins developed and maintained by Anthropic, and external plugins from third-party partners and the community. Developers can install any listed plugin with a single command: `/plugin install {plugin-name}@claude-plugins-official`, or browse available options through Claude Code's `/plugin > Discover` interface.
The marketplace introduces a structured plugin architecture. Each plugin follows a standard directory layout with a required `plugin.json` manifest, optional MCP server configurations, slash commands, agent definitions, and skill bundles. Anthropic has also established that plugin names are immutable slugs — once published, a name cannot change without a migration entry in a `renames` map, preventing installation breakage for existing users.
A notable feature is support for "skill-bundle plugins" — repositories that ship SKILL.md files without a full plugin manifest. The marketplace can declare these skills directly with an explicit array, registering them as named skills in Claude Code without requiring the full plugin infrastructure.
The launch arrives as a wave of third-party skill and plugin frameworks — including obra/superpowers and mattpocock/skills, both trending on GitHub today — are converging on Claude Code as a platform. Anthropic's official directory provides a canonical reference point for quality standards and distribution, potentially consolidating a fragmented plugin ecosystem.
