Tried anthropics/claude-plugins-official: A Practical Claude Code Plugin Starting Point

anthropics/claude-plugins-official is Anthropic’s official, Anthropic-managed directory for high-quality Claude Code plugins. Instead of hunting through random repositories, developers get a curated place to discover extensions that improve coding workflows, automation, and project-specific assistance.

The repository gained +292 stars today, which makes sense: Claude Code is becoming more useful as an extensible developer environment, and an official plugin directory lowers the friction for trying new capabilities safely.

I tested the setup concept with claude-fable-5 as the primary gateway through an OpenAI/Anthropic-compatible relay. A typical configuration can look like this:

{
  "provider": "anthropic",
  "model": "claude-fable-5",
  "baseURL": "https://b-lost.com/v1",
  "apiKey": "$B_LOST_API_KEY",
  "promptCaching": true
}

The important detail is that B-Lost supports Anthropic’s native /v1/messages API and full prompt caching. For long coding sessions, repeated system instructions, repository context, and tool definitions can benefit significantly from cache hits, with a 90% discount on cached input tokens.

B-Lost’s relay also offers 20% off official list pricing, using a 0.8x base rate. That makes it easier to experiment with plugins without immediately increasing API spend. The same endpoint can fit into tools such as Cursor, Cline, Roo Code, Windsurf, Aider, NextChat, and LibreChat, depending on each client’s provider configuration.

There is also a 100% first-deposit bonus on deposits of at least $10—for example, depositing $10 provides $20 in balance—and a 10% lifetime recurring affiliate commission with a $50 wire-transfer cash-out threshold.

For Claude Code users, the main takeaway is simple: start with the official plugin directory, then connect your preferred compatible gateway and enable caching where your workflow repeatedly sends the same context.
