harness-lab: Skill for Claude Code

.agents/skills/source-command-refactor/SKILL.md

source-command-refactor is a skill for Claude Code, Codex from Joe-rq/harness-lab. It costs 25 tokens per session (630 once invoked), scanned A, original, MIT.

A guided command workflow for creating a refactoring request, meaning a structured plan to improve existing code without changing its behavior.

In plain words
What is it for?
Use it with the `/refactor` command to document a restructuring task, its current problem, non-goals, design needs, and implementation start point.
Why use it?
It captures the reason for the refactor, highlights limits on scope, and reminds the team to preserve behavior and keep all tests passing.

Skill for Claude CodeCodex

Written for no agent in particular: nothing here depends on one. Also seen: names the AskUserQuestion tool; installed under .agents/ (shared by several agents).

This is Joe-rq/harness-lab's own configuration. It tells Claude Code and Codex how to work on harness-lab itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything harness-lab configures →

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

source-command-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 2mo 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

source-command-refactor

Use this skill when the user asks to run the migrated source command refactor.

Command Template

/refactor

目标

引导用户创建 refactor 型 REQ。

前置检查

  1. 确认 requirements/ 目录存在。不存在 → 提示先运行 /harness-setup
  2. 确认 package.json 中有 req:create 脚本。不存在 → 提示先运行 /harness-setup
  3. 运行 npm run req:status 确认当前 worktree 无活跃 REQ。有活跃 REQ → 提示先完成或搁置当前 worktree 的 REQ;如需并行新开一条线,改用 source-command-worktree-req
  4. 如需查看全局并行状态,运行 npm run req:status -- --all

执行步骤

Step 1: 收集重构信息

使用 AskUserQuestion 询问:

  1. 重构目标(必填):要重构什么?如"将 session 管理从中间件抽取为独立模块"
  2. 当前问题(必填):为什么需要重构?如"session 逻辑散布在 5 个文件中"
  3. 为什么现在做(可选):触发原因

Step 2: 创建 refactor REQ

运行:

npm run req:create -- --title "refactor: [重构目标]" --type refactor

Step 3: 补充重构详情

用 Edit 将 REQ 中的占位符替换为用户提供的实际信息:

  • [请描述技术债或流程缺口](背景-当前问题)→ 用户的当前问题
  • [请描述触发原因](背景-为什么现在做)→ 用户的触发原因
  • [模块/流程](目标-重构)→ 用户的重构目标

Step 4: 提示用户确认

重点提醒:

  1. 确认"非目标"中的"不做功能行为变更"是否符合预期
  2. 如果涉及文件数 ≥4,考虑是否拆分 REQ
  3. 补充"颗粒度自检"
  4. 确认后运行 npm run req:start -- --id {reqId} --phase implementation

输出

  1. 创建的 REQ ID 和文件路径
  2. REQ 类型:refactor
  3. 已预填充:技术债描述占位、行为不变约束、skip-design-validation
  4. 核心约束提醒:重构后所有测试必须通过,行为不能变

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.
