prompt-caching An MCP plugin that helps developers understand, optimize, and debug Anthropic's prompt caching in their own applications — with tools for injecting breakpoints, analyzing cacheability, and tracking real-time cache savings. Who is this for? This plugin is built for developers building their own applications with the Anthropic API. Important note for Claude Code users: Claude Code already handles prompt caching automatically for its own API calls — system prompts, tool definitions, and conversation history are cached out of the box. You cannot add more caching on top of Claude Code's own sessions, and you don't need to. See Anthropic's prompt caching docs for details on how automatic caching works. This plugin is useful when: You are building an app or agent wi

Grades come from a rule-based scan built on the SlowMist agent-security taxonomy, covering 11 red-flag categories including credential harvesting, data exfiltration, and curl | sh installers. It is a first-layer scan, not a manual audit — we say so rather than overstate it.
The scale of the problem is documented independently: Liu et al. (2026), in a study of 31,132 agent skills, report that 26.1% contain security vulnerabilities. Our own full-catalog census is published as a citable open dataset.
