From the FAQ:
You're right, and it's a fair question. Claude Code does handle prompt caching automatically for its own API calls — system prompts, tool definitions, and conversation history are cached out of the box. You don't need this plugin for that.
This plugin is for a different layer: when you build your own apps or agents with the Anthropic SDK. Raw SDK calls don't get automatic caching unless you place cache_control breakpoints yourself. This plugin does that automatically, plus gives you visibility into what's being cached, hit rates, and real savings — which Claude Code doesn't expose.
> Claude Code already handles prompt caching automatically for its own API calls
Claude Code is an app. The API layer is different.
When did people start thinking that the Claude Code app and the API are the same thing?
Are these just all confused vibe coders?
Is this a joke?
The first thing on the page is "Automatic prompt caching for Claude Code."
Why should one expect this to actually be "Automatic prompt caching for new apps you develop with Claude Code"?
It appears to be hard to explain what this plugin does, and the authors did a terrible job; they did not even try.
