自动清理代码冗余注释并标记技术债

输入：代码仓库与团队注释规范；处理：扫描、分类、删除冗余注释，保留非显而易见的 why 注释，标记 workaround；输出：一个行为不变的 PR，附带待修复的根因清单

给谁

需要维护代码质量、减少注释膨胀的工程师团队；适合已有基本 CI/CD 流程的仓库

你会得到

生成一个仅删除冗余注释的 PR，不改变代码行为，并在 PR 描述中列出发现的 workaround 根因

你需要

步骤

1. 创建 Comment Cleanup 机器人并填入角色描述

   在你的 AI 平台（如 GrokBot）中新建一个 bot，将下方角色描述粘贴到系统提示词字段。替换所有 {PLACEHOLDER} 为实际值：{NAME} 为 bot 名称（如 CommentSicko），{REPO} 为目标仓库，{LICENCE HEADERS} 为需保留的许可证头标识。

   搭建指导 · 来源原文。AI 平台的系统提示词 / System Prompt 字段；替换变量后保存

   复制提示词

   You are {NAME}. Your one job is deleting unnecessary comments in
   {REPO}. Remove: comments that restate the code, commented-out blocks,
   "keeping this just in case", and comments that explain a hack instead
   of fixing it. Keep: {LICENCE HEADERS}, and comments that state a
   non-obvious *why* that the code cannot express.
   
   When a comment describes a workaround, do not just delete it — list it
   in the PR description as a root cause to fix.
   
   Open one PR. Behaviour must be unchanged; attach the test run.

2. 配置触发器与排除路径

   设置触发方式：选择夜间定时运行，或保留 `/no comments` 命令触发、PR review flag 触发。在配置中填入 {EXCLUDED PATHS}，指定 bot 不得修改的目录或文件（如第三方库、自动生成的代码）。确认审批流程：任何触及排除路径或可能改变行为的删除需人工审核。

3. 执行扫描与注释分类

   Bot 按角色描述扫描目标仓库：识别并标记四类需删除项——重复代码语义的 what 注释、已注释掉的代码块、"keeping this just in case" 类注释、以及解释 hack 而非修复它的注释。同时保留：许可证头、代码无法表达的非显而易见 why 注释。若注释揭示 workaround，单独记录为根因待修复项，不直接删除该记录。

4. 生成 PR 并附加验证

   Bot 打开一个 PR，仅包含注释删除，无代码逻辑变更。PR 描述需包含：删除的注释类别汇总、发现的 workaround 根因清单。必须附加测试运行结果，证明行为未改变。等待 CI 通过及人工审批后合并。
