What it does
Harness Start is an agent skill from k1ein-chen/Harness-Starter. Entry point for new users — guides through initialization, architecture review, and cleanup. Use when the user first opens this project or says "开始" / "初始化" / "怎么用".
Its SKILL.md is about 720 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 Software architecture. The repository describes itself as: 一套成熟完善的开箱即用的 Claude Code Harness Engineering 模板。三层自动化（安全/感知/审查），集成 LSP、OpenSpec SDD 工作流和 AI 一键初始化。新项目和已有项目均可使用。 The licence is MIT.
When your agent uses it
- The user first opens this project
- Says 开始 / 初始化 / 怎么用
Example prompts
- “/harness-start”
Requirements
- Python 3
Workflow steps
4 steps, taken from the step headings in SKILL.md.
What it can do on your machine
Read from SKILL.md and the folder at commit c211c43. 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
Shell commands in SKILL.md call:
node
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
Harness Start loads about 718 tokens when it runs. Until then it costs about 45 tokens; SKILL.md has 153 words of instructions outside code blocks.
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.

Harness Start
你是刚打开这个模板的人。无论你手头是空项目还是做到一半的项目，四步走完即可就位。
Step 1：初始化
直接说：
帮我初始化 HarnessAI 会自动执行 harness-init 全流程：检测技术栈 → 填写 CLAUDE.md → 发现 Skill 路由 → 检查 Hook → 安装 LSP → 健康检查。
如果已经在 CLAUDE.md 里填过内容，AI 不会覆盖你写好的部分。
Step 2：整体看一下架构
初始化完成后，说：
帮我梳理一下当前项目架构AI 会遍历项目文件，输出一份架构概览——目录结构、模块关系、入口文件都在哪里。这一步让你（也让 AI）对项目全貌建立共识，后续改动才有上下文。
Step 3：第一性原理清洗
初始化完成后，AI 已经知道了你的项目是什么。现在基于项目的第一性原理（项目本质、技术栈、核心目标），反向检查 CLAUDE.md 和项目目录里有没有不属于这里的东西。
清洗范围
| 维度 | 检查什么 | 示例 |
|---|---|---|
| 🧠 CLAUDE.md 规则 | 每条规则是否与项目相关？ | 个人博客不需要 tech-review 引用 |
| 📁 项目目录 | 模板文件是否仍残留？ | scripts/gc-scan.mjs 对于简单项目可能多余 |
| 🛠️ 技术栈对齐 | CLAUDE.md 中提到的技术是否项目在用？ | 纯 Python 项目不应引用 TypeScript |
| 🎯 目标对齐 | 规则是否服务于项目目标？ | 博客项目不需要 CI 检查 |
执行规范
- 每条建议必须说明理由，不得只说"删除"不说"为什么"
- 必须等用户确认，用户点头才能改
- 用户拒绝的要尊重，不能追问"确定吗"
- 一轮最多提 5 条，避免轰炸用户
输出格式
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
🔍 第一性原理清洗
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
根据初始化时获取的信息：
项目类型：{检测到的项目类型}
技术栈：{检测到的技术栈}
核心目标：{用户告知的项目目标}
─────────────────────────────────────
清洗建议（共 N 项）：
[1/N] CLAUDE.md · {文件位置}
现状：{当前内容}
理由：{为什么不符合项目第一性原理}
建议：{具体修改操作}
确认？(y/n) →
[2/N] 项目目录 · {文件/目录路径}
现状：{当前内容}
理由：{为什么可以删除或修改}
建议：{具体操作}
确认？(y/n) →
...
─────────────────────────────────────
所有建议处理完毕，进入下一步验收。提醒：CLAUDE.md 的行为准则部分（Karpathy 6 条）是通用原则，对所有项目都有价值，不建议裁剪。重点关注的是"进阶特性"和"具体技术引用"。
Step 4：验收 — 检查是否就位
四步执行完毕时，AI 必须执行以下验收检查并输出结果。不得以"做完了"笼统收尾。
检查项
| # | 检查项 | 自动/手动 | 证据来源 |
|---|---|---|---|
| 1 | CLAUDE.md 无占位符 | 自动 | grep '【待填写】' CLAUDE.md → 0 匹配 |
| 2 | 第一性原理清洗完成 | 手动确认 | Step 3 逐条确认记录完整 |
| 3 | 3 个核心 Hook 已注册 | 自动 | .claude/settings.json 中 PreToolUse/SessionStart/Stop 齐全 |
| 4 | LSP 可用 | 自动 | 检查 language server 安装状态 |
| 5 | 健康检查通过 | 自动 | node scripts/check.mjs 输出全绿 |
| 6 | 项目能正常运行 | 手动确认 | 根据项目类型执行对应的 run 命令 |
验收输出格式
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
✅ 初始化验收报告
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
[#1] ✔ CLAUDE.md 已填写 — 无【待填写】占位符
[#2] ✔ 第一性原理清洗完成 — N 项建议已处理
[#3] ✔ 3 个核心 Hook 已注册 — PreToolUse / SessionStart / Stop
[#4] ✔ LSP 可用 — {language-server}
[#5] ✔ 健康检查通过 — node scripts/check.mjs → 全绿
[#6] ✔ 项目可运行 — {run command} → exit 0
─────────────────────────────────────
结论：全部通过 ✅ 项目已就位
─────────────────────────────────────含 ✘ 的项不处理完毕，四步流程不算结束。
做完四步之后
你的项目就脱离模板状态了。之后正常开发即可——每次会话 AI 会自动加载 git 状态、审查记录和 Loop 状态。
下次打开新项目时，AI 会重新执行以上四步流程，根据新项目的"第一性原理"重新清洗。
关于 tech-review：Harness Starter 内置了技术方案审查能力。当你在开发中要求 AI 实现某个技术方案时，AI 会自动审查该方案在当前行业是否仍然是最佳实践。详见

Can I use Harness Start in Cursor, Gemini CLI or GitHub Copilot?
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add k1ein-chen/Harness-Starter --skill harness-start -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/harness-start, .gemini/skills/harness-start, .github/skills/harness-start and .opencode/skills/harness-start in your project.
What does Harness Start need to run?
Going by SKILL.md and its folder, Harness Start needs the command-line tools its instructions call (node). Our summary lists: Python 3.
Does Harness Start access the network?
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Is Harness Start safe to install?
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
What licence does Harness Start use?
Harness Start is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
How many tokens does Harness Start use?
About 718 tokens (SKILL.md is roughly 2.9k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
