refactor-clean

A command for finding and removing unused code after checking that the tests still pass. Dead code is code that is no longer used.

In plain words
What is it for?
Use it to analyze unused files, exports, and dependencies, produce a report, and safely remove only changes supported by test checks.
Why use it?
It helps reduce clutter while lowering the risk of deleting code that the project still needs.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Made for: Claude Code.

Per session 0 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 231 The whole file, excluding the scripts and references it only reads on demand.
Security scan A 0 findings. Scan, not verified.
Origin original No closer match found in the catalogue.
Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

refactor-clean scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

重构清理 (Refactor Clean)

在测试验证下安全地识别和移除死代码。

  1. 运行死代码分析工具:

    • knip: 查找未使用的导出和文件
    • depcheck: 查找未使用的依赖
    • ts-prune: 查找未使用的 TypeScript 导出
  2. 在 .reports/dead-code-analysis.md 生成综合报告

  3. 按严重程度分类发现:

    • 安全 (SAFE): 测试文件,未使用的工具函数
    • 警告 (CAUTION): API 路由,组件
    • 危险 (DANGER): 配置文件,主入口点
  4. 仅建议安全删除

  5. 每次删除前:

    • 运行完整测试套件
    • 验证测试通过
    • 应用变更
    • 重新运行测试
    • 如果测试失败则回滚
  6. 显示已清理项目的摘要

在先运行测试之前,绝不删除代码!

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

refactor-clean is a command published in the GitHub repository cfrs2005/claude-init (1,364 stars, last pushed 5mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 231 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
