What it does

Refactor Safety is an agent skill from doccker/cc-use-exp. 当用户要求重构代码（提取组件、合并重复逻辑、重命名变量、优化结构）时触发。提供重构安全检查清单，防止丢失原始上下文。

Its SKILL.md is about 2.4k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Development, covering Refactoring. The repository describes itself as: ⛔ No longer maintained → dev-agent-kit/recipes 让 Claude Code、Antigravity、Gemini CLI、Codex、Cursor 开箱即用的分层配置模板，总结十多年的日常开发经验.

When your agent uses it

  • Tasks that involve Refactoring

Example prompts

  • “/refactor-safety”

Workflow steps

12 steps, taken from the step headings in SKILL.md.

  1. 读取原始代码（必须）
  2. 制作对比清单
  3. 验证检查点
  4. 输出格式
  5. 假设驱动重构
  6. 记忆重构
  7. 跳过验证
  8. 提取子模块导致循环依赖
  9. 提取状态管理时的初始化冲突
  10. UI 组件重构时的布局结构丢失
  11. 复杂渲染逻辑被简化替换
  12. 字段名推测重构（极其隐蔽）

What it can do on your machine

Read from SKILL.md and the folder at commit 64470cb. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md (its code samples are typescript, javascript, markdown, java and bash).

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Refactor Safety loads about 2.4k tokens when it runs. Until then it costs about 19 tokens; SKILL.md has 251 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~19
When it runs · the whole SKILL.md, loaded when a task matches
~2.4k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 251 words (~2,364 tokens).
