refactor

A guided command for restructuring existing code without changing what it does. It asks for the file and refactoring goal, then proposes small, test-protected changes for approval.

In plain words
What is it for?
Use it to analyze code, plan and apply refactorings such as extracting functions or renaming symbols, and check the result with type checks and tests.
Why use it?
It helps reduce duplication, deep nesting, unclear names, and overly large functions while lowering the risk of accidental behavior changes.

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.

Clone the repo
git clone --depth 1 https://github.com/echoVic/blade-code
Per session 6 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 350 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 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.

请帮我重构以下代码。

重构原则

  1. 保持行为不变:重构不应改变外部可观察的行为
  2. 小步前进:每次只做一个小改动
  3. 测试保护:确保有测试覆盖,或先补充测试
  4. 代码整洁
    • 函数单一职责
    • 避免过深嵌套
    • 有意义的命名
    • 减少重复代码

重构清单

请按以下步骤进行:

  1. 分析现状:指出当前代码的问题
  2. 制定计划:列出重构步骤
  3. 逐步执行:每一步都展示变更
  4. 验证结果:运行类型检查和测试

常用重构手法

  • 提取函数 (Extract Function)
  • 内联函数 (Inline Function)
  • 提取变量 (Extract Variable)
  • 重命名 (Rename)
  • 移动函数 (Move Function)
  • 用多态替换条件 (Replace Conditional with Polymorphism)

请先分析代码问题,然后告诉我你的重构计划,等我确认后再开始执行。

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 is a command published in the GitHub repository echoVic/blade-code (177 stars, last pushed 2d ago), licensed MIT. It adds 6 tokens to every session and 350 once invoked, about $0.0000 per session on Opus 5. 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.
