附带一个 MCP 中间件工具（caveman-shrink），可包裹任意 MCP server 以压缩其工具描述。
限制与风险
caveman 仅缩减输出 token，输入 token 与推理 token 不受影响。
如何开始
项目自述标注安装难度为 easy，用户可通过 CLI 方式安装并选择压缩等级。

GitHub 项目简介: 🪨 why use many token when few token do trick
README: Caveman is a skill/plugin for [Claude Code](https://docs.anthropic.com/en/docs/claude-code), Codex, Gemini, Cursor, Windsurf, Cline, Copilot, and 30+ other agents.
README: Agent drops the filler and answers in tight caveman-speak, keeping code, commands, and errors byte-for-byte exact. You save output tokens on every reply, forever.
README: works_with-30%2B_agents-orange
README: ~30 seconds. Needs Node ≥18. Skips agents you no have. Safe to re-run.
