pdlc-refactor

pdlc-refactor is a skill for Claude Code from kanfu-panda/pdlc-skills. It costs 21 tokens per session (464 once invoked), scanned A, original, MIT.

A refactoring workflow for improving a program's internal structure while keeping its observable behavior the same. It uses existing tests, small changes, and repeated test runs to reduce risk.

In plain words
What is it for?
Use it to split oversized methods or classes, remove duplication, simplify conditions, improve names, reduce coupling between modules, and align code with project conventions.
Why use it?
It helps clean up difficult code without quietly adding features or changing how the program works. Checking tests after each step makes accidental behavior changes easier to detect.

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

pdlc-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 11d 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

代码重构

对指定服务或模块进行安全重构,保证行为不变。

工作流程

  1. 确认测试覆盖: 先检查现有测试是否充分,不充分则先补测试
  2. 阅读设计文档: 阅读 docs/02_design/ 对应子目录下的相关设计文档
  3. 识别坏味道: 分析代码中的坏味道(Code Smell)
  4. 制定重构计划: 列出重构项,按风险排序
  5. 逐步重构: 每次只做一个小的重构,确保测试通过
  6. 运行完整测试: 确认没有破坏现有功能

常见重构场景

  • 提取方法/类: 过长的方法、过大的类
  • 消除重复: DRY 原则,提取公共逻辑
  • 简化条件: 复杂的 if-else 链、嵌套条件
  • 改善命名: 不清晰的变量名、方法名
  • 解耦依赖: 降低模块间耦合度
  • 统一风格: 对齐项目编码规范

要求

  • 重构提交信息格式: refactor: <简要描述>
  • 严禁在重构中混入新功能
  • 每个重构步骤都要保证测试通过
  • 更新 CHANGELOG.md

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.

pdlc-refactor is a skill published in the GitHub repository kanfu-panda/pdlc-skills (13 stars, last pushed today), licensed MIT. It adds 21 tokens to every session and 464 once invoked, about $0.0001 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 2026-08-31.
