No dead code
Never assume dead code (cross-agent safety). Before deleting any symbol (function/class/variable/file), grep every caller. After adding a file, update the project manifest. When multiple agents edit in parallel, re-read the latest file before editing — don't trust a cached copy. Triggers when about to delete a symbol, add a source file, or edit a file that may be concurrently modified. 不假设 Dead Code:删任何符号前先 grep 所有调用方;新增文件后更新清单;多 agent 并行时编辑前先读最新文件;看到"像是没用"的符号先 grep 再说。 消歧:多文件接口改造的逐文件 build 节奏归 incremental-build,本 skill 只管"删/改符号前证明安全"。From its SKILL.md

Never Assume Dead Code / 不假设 Dead Code
"Nobody uses this" is a hypothesis, not a fact. Grep proves it; memory doesn't. "没人用这个"是假设不是事实。grep 能证明,记忆不能。
The discipline / 纪律
- Before deleting a function/variable, grep all callers across the repo. 删除函数/变量前,grep 所有调用方。
- After adding a file to the project, update the manifest (
package.json,go.mod, exports index, etc.). 新增文件后,更新项目清单(package.json、go.mod、导出索引等)。 - With agents working in parallel, re-read the latest file before editing — never rely on a cached view. 多 agent 并行时,编辑前重新读最新文件——绝不依赖缓存视图。
When this triggers / 触发时机
- About to delete a function / class / variable / file.
- About to add a source file / module.
- About to edit a file that another agent may be modifying concurrently.
- You spot a symbol that "looks unused".
Done criterion (verifiable) / 完成判据（可验证）
✅ Before the deletion, you ran a repo-wide grep for the symbol and it returned zero live callers (and you can show the search). New files are registered in the manifest. For a possibly-concurrent edit, there's a fresh Read of the file in this turn right before the edit. ⚠️ Grep found callers — those are not dead; handle them or stop. ❌ You deleted on the assumption it was unused, without searching. Restore and grep first.
