变更校验关卡

> 看清「改了什么、影响哪里、文档是否跟上」——是变更的体检,不是审查替代品。

何时使用

| 场景 | 跑 | 判据 | |------|------|------| | 提交前(任何代码改动) | ✅ | 默认门禁 | | 重构完成 | ✅ | 评估辐射面 | | 设计级改动 | ✅ | DESIGN.md 是否同步 | | PR review | ✅ | 替代手工 diff 计数 | | 跨模块大改 | ✅ | 看依赖图是否成环 | | 紧急 hotfix | ⚠ | 跑,但允许文档同步延后到稳定后 |

三种模式

| 模式 | 时机 | 用途 | |------|------|------| | `working` (默认) | 写代码过程中 | 自检,看「我现在的工作面有哪些待整理」 | | `staged` | `git add` 后、`commit` 前 | 提交闸,看「这一 commit 的合理性」 | | `committed` | commit 完成后 | review,看「上一段历史改了哪些范围」 |

警告判定

| 警告 | 触发 | 处置 | |------|------|------| | 代码 >50 行 而 DESIGN.md 未更新 | 设计层面变化未留痕 | 补 DESIGN.md「改了什么/为何」段 | | 代码 >30 行 而无测试更新 | 测试覆盖滞后 | 补单测/集成测;或在 PR 注明「该路径已有 E2E 覆盖」 | | 新增文件而 README.md 未更新 | 用户视角文档滞后 | 补模块入口说明 | | 配置变更未记录 | 部署可能踩坑 | CHANGELOG / DESIGN 留迁移说明 | | 删除文件 | 引用可能未清理 | 全仓 grep 文件名/导出符号 |

解读输出

工具产出三类信号:

1. **文件分类** — 自动分代码/文档/测试/配置;用于判断「是否纯文档变更」 2. **模块识别** — 把变更聚到模块边界;用于判断「跨模块改动」 3. **影响评估** — 行数 + 文件数;用于判断「改动是否需要拆 PR」

> **拆 PR 的判据**(基于 commit 角度): > - 跨 ≥3 模块且无统一主题 → 拆 > - 单 commit >500 行非生成代码 → 拆 > - 一次同时改架构 + 实现 + 文档 → 通常合理(同主题)

与其他 skill 联动

  • 设计级变更 → 触发 [verifying-modules](../verifying-modules/SKILL.md) 看新模块文档完整性
  • 安全相关变更 → 触发 [analyzing-security](../analyzing-security/SKILL.md)
  • 重构 → 触发 [checking-code-quality](../checking-code-quality/SKILL.md) 防退化

使用

node scripts/change_analyzer.js                   # working(默认)
node scripts/change_analyzer.js --mode staged     # 暂存区
node scripts/change_analyzer.js --mode committed  # 已提交
node scripts/change_analyzer.js -v                # 详细
node scripts/change_analyzer.js --json            # CI 用

人工复核

工具给信号,人下结论。先读受影响模块 README/DESIGN,确认:

  • 职责边界是否仍清晰
  • 设计决策是否仍成立
  • 测试是否覆盖新路径

设计级改动须于 DESIGN.md 留痕:**改了什么、为何改、影响何处**。三段缺一不可。
