What it does
Tech Review is an agent skill from k1ein-chen/Harness-Starter. Reviews technical decisions before implementation. Detects outdated or suboptimal approaches by searching current best practices. Use when the user asks to implement something using a specific tool, library, or methodology.
Its SKILL.md is about 400 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
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 asks to implement something using a specific tool
Example prompts
- “Use the tech-review skill to review technical decisions before implementation. An agent skill from k1ein-chen/Harness-Starter”
- “/tech-review”
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
No scripts in the folder and no shell commands in SKILL.md.
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
Tech Review loads about 396 tokens when it runs. Until then it costs about 59 tokens; SKILL.md has 60 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.

Tech Review
核心理念
用户因为信息差给出了过时或不优的技术方案时，AI 有责任在执行前发现并告知。
这不是"违抗用户指令"——不执行是违抗，发现更好的方案并告知是专业化。
触发条件
必须触发：用户指令中包含"用 [X] 做 [Y]"结构的技术实现请求。X 是一个工具/库/框架/方法论，Y 是一个目标。这种结构意味着用户已经做了技术选型，这个选型需要被验证。
不触发的典型场景：
- 纯业务逻辑（"写个登录接口"——不指定具体工具）
- 纯 debug（"修一下这个 bug"）
- 纯配置变更（"把端口改成 3000"）
- 用户明确说"按我说的做，不用查"
- 你 100% 确定该方案仍是当前最佳做法
不确定要不要触发？宁查勿漏。多一次搜索远比让用户走弯路划算。
工作流
Step 1：提取技术决策
识别用户指令中所有"用 X 做 Y"性质的技术决策。可能不止一项。
Step 2：搜索验证
对提取出的每一项技术决策，执行 web search。搜索词不限以下示例，根据实际情况组织：
[X] alternative
[X] vs [已知替代方案]
[X] deprecated
[场景描述] best practice每次审查至少搜索一次。即使你认为自己的知识是准确的，也搜索确认——因为你不知道你的训练数据截止到什么时候。
Step 3：输出审查报告
使用以下固定格式输出结果：
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
🔍 技术方案审查
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
审查结果：[ ✅ 方案可行 / ⚠️ 有更好的选择 / ❌ 方案不推荐 ]
涉及的技术决策：
1. [选型 A] → [结论，附搜索来源概要]
2. [选型 B] → [结论，附搜索来源概要]
[审查结果为 ✅]
当前方案仍是最佳做法，按原计划执行。
[审查结果为 ⚠️ 或 ❌]
替代建议：
- 方案一：[名称] — [简要说明]
- 方案二：[名称] — [简要说明]
─────────────────────────────────────
请选择：A) 按原方案继续 B) 改用建议方案 C) 我自己调整
─────────────────────────────────────Step 4：等待选择
- A — 尊重用户意愿，按原方案执行，不再质疑
- B — 替换为建议方案，继续执行
- C — 用户修改需求后重新来过
- 用户不回复 — 不继续执行
说明
- 这个 Skill 的价值不在于"AI 替用户做决定"，而在于消除信息差
- web search 会产生费用，但这是为了换取正确性
- 如果同一领域的同类决策已在本次对话中审查过，可以跳过重复搜索
