Analyzing Changes
Analyzes code changes, detects documentation drift, and evaluates change impact scope. Use when reviewing diffs, checking doc sync, or running pre-commit analysis. Automatically triggered after design-level changes or refactoring.

What Analyzing Changes is
Analyzing Changes is a skill published in the telagod/code-abyss repository on GitHub, which has about 241 stars. The repository describes itself as: “Give your AI coding agent a personality. Composable persona + style + skills for Claude Code, Codex, Gemini CLI & OpenClaw. Ships Tech Persona Card v1.0 spec.”
A skill is a folder with a SKILL.md file: frontmatter with a name and a description, followed by instructions Claude follows. Claude loads a skill automatically when a task matches its description, and you can also run it directly with a slash and its name.
Skills work in Claude Code and in Claude Cowork, which makes Analyzing Changes a portable way to give Claude the same method everywhere.
How to install Analyzing Changes
Claude Code
- Download the analyzing-changes folder from the repository.
- Save it as ~/.claude/skills/<skill-name>/SKILL.md for all projects, or .claude/skills/<skill-name>/SKILL.md for one project.
- Claude loads it automatically when a task matches; you can also run it with / and its name.
Claude Cowork
- Zip the skill folder so SKILL.md sits at the top level of the folder.
- Open Customize → Skills, click +, then upload the ZIP.
- Start a task that matches the description, or call it by name with /.

何时使用
三种模式
警告判定
解读输出
工具产出三类信号：
- 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」
- 模块识别 — 把变更聚到模块边界；用于判断「跨模块改动」
- 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 看新模块文档完整性
- 安全相关变更 → 触发 analyzing-security
- 重构 → 触发 checking-code-quality 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。
Before you install
- Read the whole file first. Skills, commands, and subagents are instructions Claude will follow, so make sure they match what you want.
- Check which tools, scripts, or MCP servers it uses. Local servers and scripts run with your permissions.
- Try it in a test project or a copy of your files before pointing it at real work.
- Pin the version you tested, and review changes before updating.
- Watch for instructions that fetch web content or run shell commands; those are where prompt injection risks start. See our prompt injection guide.
