## 入选理由

用Agent分析CI提速，含具体数据

## 内容

Claude Code 和 Codex 现在一天能推几十个拉取请求。写代码只用几分钟，剩下的时间都在等 CI，也就是每次推送后 GitHub 运行的检查与测试。

九项改动，把每个拉取请求的 CI 从最长 40 分钟缩短到了 2 分钟。其中一步，是让 Agent 拉取最近 150 次 CI 运行，把每个任务拆成三个部分：等机器、环境准备、实际执行。仅这一步就发现，一半测试任务根本没有使用依赖缓存，这个问题已经存在整整一年了。

把这段提示词交给 Claude Code 或 Codex，先查明你的 CI 时间花在哪里，再逐项缩短 👇

"Audit this repo's CI:
1. Use gh to pull the last 150 CI runs and split each job's time into three parts: waiting in the queue for a machine, setup (checkout, installing dependencies, restoring the cache), and actually running the task. List the 5 slowest jobs and how many seconds each part takes.
2. Check these 9 things one by one: queueing on the default runners; slow lint; slow typechecking; tests that aren't sharded, or machines that are too small; every test file reloading the whole app; slow setup (cache misses, clones that aren't blobless, more parallel tasks than cores); jobs that don't run in parallel; every PR running the full test suite; no local checks before push.
3. For each problem, tell me how many seconds it costs now, which line of which file to change, and roughly how much it would save. List the ones that cost more money (new runners, bigger machines) or run fewer tests separately for me to decide.
Give me the report first. Don't change anything."
