Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

dsh-refactor-insight

v0.1.3

Published

DSH refactor-insight skill plugin: turn codebase smells into an executable, priority-ordered refactoring plan (file-length, long-function, deep-nesting, god-object, high-coupling, and TODO-density heuristics plus a staged runbook).

Readme

dsh-refactor-insight

DSH 技能插件:把代码库的坏味道转成带定位、优先级和依赖顺序的可执行重构计划——结构健康体检,而非 diff 审查。

Turn codebase smells into an executable, priority-ordered refactoring plan.

能力(v0)

六条确定性坏味道规则(阈值均可参数覆盖,零依赖启发式):

  • 超长文件(默认 > 400 行)
  • 深嵌套(默认最大缩进 / 花括号深度 > 5)
  • TODO/FIXME 密度(噪音指标,输出每千行计数)
  • 长函数(Python 缩进块 / JS-TS 花括号配对 / Go 函数声明,函数体 > 80 行)
  • 上帝对象(类方法数 > 10 或类体行数 > 300 / Go 接收者方法数)
  • 高耦合模块(复用 arch-profile --deps 输出,按入度/出度识别 hub 模块 + Tarjan 环检测)
  • 只输出计划、不自动改代码;高风险重构项由 LLM 标注、须人工确认。

脚本只给硬事实(确定性扫描),严重度 / 成本 / 建议动作由 LLM 精修真误报后标注推断。

快速开始

在 DSH 中使用

  1. 安装插件:dsh plugin --profile web add github:duyanta123/dsh-refactor-insight
    • 发布 v0.1.0 tag 后,可改为 github:duyanta123/dsh-refactor-insight#v0.1.0 锁定版本。
  2. 使用:对 Agent 说「用 refactor-insight 体检 /path/to/repo」
  3. 输出:按 docs/refactor-plan-template.md 生成 REFACTOR-PLAN.md

只跑诊断 CLI(零依赖,不经过 DSH 也能跑)

独立 refactor-smell.mjsarch-profile.mjs 继续支持 Node.js >= 18;作为 DSH 0.1.5-rc.2 bundle 运行时要求 Node.js >= 22.19。兼容门禁可用 npm run test:compat

# 六条规则诊断
node scripts/refactor-smell.mjs <repo_path>

# 复用 arch-profile 的依赖输出做高耦合/环检测
node scripts/arch-profile.mjs <repo_path> --deps > deps.json
node scripts/refactor-smell.mjs <repo_path> --deps-json deps.json

主要参数:--max-lines--max-func-lines--max-nesting--max-methods--max-class-lines--max-coupling--max-depth--include-dirs--exclude-dirs

示例输出(节选):

{
  "language": "javascript/typescript",
  "smells": [
    {
      "rule": "god-object",
      "type": "god_object",
      "path": "src/lib/GodService.js",
      "name": "GodService",
      "methods": 12,
      "threshold": 10,
      "severity": 2,
      "cost": "M"
    }
  ]
}

本地开发

  1. profile 的 package.json 加 "dsh-refactor-insight": "file:<本地路径>/dsh-refactor-insight",bundles 加 "dsh-refactor-insight"
  2. 测试:npm test
  3. 打包检查:npm pack --dry-run

输出

  • REFACTOR-PLAN.md:结构化重构计划(按 docs/refactor-plan-template.md 骨架)
