Anthropic opens Claude Code plugin directory

This is a bigger strategic move than a simple plugin bundle: Anthropic is standardizing how Claude Code extensions are packaged, discovered, and shared. That lowers the barrier for teams to move from one-off `.claude/` hacks to reusable workflows and gives Claude Code a more durable ecosystem story.

• –The official directory mixes Anthropic-built plugins with approved third-party integrations, which gives Claude Code immediate breadth across coding, review, testing, design, and backend workflows.
• –Packaging skills, agents, hooks, MCP servers, and commands behind one install surface makes advanced automation much easier to adopt across teams.
• –The marketplace model also creates a clearer path for partners like GitHub, Figma, Supabase, Slack, Vercel, and Pinecone to meet developers inside Claude Code instead of forcing custom setup docs.
• –For developers, the real win is operational: namespacing, versioning, and discoverability make Claude Code extensions feel maintainable rather than experimental.
