## AI 摘要

Cursor 宣布在不降低 Agent 质量的前提下将 token 成本降低 7%，手段包括更紧凑的提示词、按需加载工具、更好缓存和压缩文件读取。作者转发并补充称，智能体工作前后会大量读取以收集上下文，因此优化读取收益明显，建议构建 Agent 的读者参考该文章或让 Agent 直接落实这些发现。配图显示 read 是最常用工具，占 91.3% 的 Agent 会话，grep 77.8%、glob 68.5% 次之。

## 正文

agents like to read a lot to gather context before and after working, so optimizing for reading makes a big difference!

if you're building agents, i highly recommend reading this (or giving it to your agent and ask it to implement the findings)

### 引用推文

> Cursor：We've reduced token costs in Cursor by 7% with no drop in agent quality. Savings came from tighter prompts, selective tool loading, better caching, and compress...
