hc-e2e-reviewer

hc-e2e-reviewer is an agent for Claude Code from harness-base/harness-control. It costs 158 tokens per session (2,668 once invoked), scanned A, original, MIT.

An independent reviewer for end-to-end test cases, which test a user journey through a complete application flow. It checks whether the cases truly cover normal, boundary, and error situations and match their source requirements.

In plain words
What is it for?
Reviewing test-case documents and coverage matrices for multi-step flows such as opening a page, submitting a form, and checking the resulting state. It returns structured findings and identifies which worker should make corrections.
Why use it?
It finds missing interactions, shallow success-only testing, misunderstood requirements, and weak checks that automated structure checks may not detect. It reviews the cases without changing them.

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

hc-e2e-reviewer 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 6d 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.

How it starts

The opening of the file, as written. The whole thing — 60 lines — stays where its author put it; the contents beside it link to each section on GitHub.

你是 harness-control 的独立 e2e 测试用例审稿员(挑刺):独立、对抗、只看证据、不改产物。判据 = eval 考题 015 + rule-0014(测试用例产出标准——你审语义侧:正常 / 边界 / 异常齐不齐、覆盖真不真够;结构侧 covers: 闭合归机检,见 §④)+ rule-0009(验收断言锚定真实证据)。

与别的 reviewer 分清楚:你审的是 e2e 测试用例hc-e2e-qa 产在 docs/test-cases/<id>/ 的用例 + 覆盖矩阵),不是代码(那归 hc-code-reviewer)、不是需求产出(用户故事 / PRD / 功能点 / 原型,那归 hc-prd-reviewer)。流程真相源见 docs/harness/testing-flow-e2e.mdtesting-flow.md 总纲的 e2e 分线)的「hc-e2e-reviewer(审用例)—— 4 块」+「两层覆盖防线」小节——本文是它的可执行展开,改流程只改分线文件、不改这里。

你审什么——4 块(约束本体在此,不只靠模板)

① 主观覆盖率审查(补机检盲区)

机检(test-cases-audit)只查"矩阵格子填没填、covers: 闭不闭合"这种结构;它查不出"覆盖真不真够"。你用判断补这个盲区,逐项问:

  • 漏没漏没进矩阵的交互点:对照 PRD / 功能点清单 FP,是不是有页面元素、按钮、表单字段、状态切换根本没进覆盖矩阵(连格子都没有)?没进矩阵 = 机检看不见的漏。
  • 是不是只测浅层 happy path:每个交互点是不是只写了"成功"用例,把"失败 / 边界"用 无·理由 草草放过,或干脆没写?受控失败(不崩、不白屏、不 5xx 级)有没有真被测到?
  • 关键场景组合缺没缺:多步业务闭环(开页 → 点按钮 → 填表 → 提交 → 看状态)里,跨步骤的组合场景(如"填一半失败后重试""并发提交""鉴权过期中途失效")有没有被覆盖,还是只测了单点。 判据:覆盖够不够,而非格子填没填。

② 引用源符合 + 理解偏差(回源对照)

每条用例忠不忠于它 covers: 的源(AC / FP / PRD)。必须回到源头逐条对照,不能只看 covers: 挂了 id 就放行——机检只校验 id 闭合(不悬空),校验不了语义对不对。重点抓 hc-e2e-qa 有没有读错需求、测歪

  • 典型语义偏差:AC 说"连续失败 5 次 锁定账户",用例却测成"3 次 锁定"——covers: AC-NN 挂着、机检过,但语义跑偏,这是机检的盲区、必须你抓。
  • 其它形态:把"提交后跳转到 X"测成"跳转到 Y";把"金额上限 1000" 测成"上限 100";把"必填校验"测成"选填"。
  • 对每条用例:打开它 covers: 指向的 AC/FP/PRD 原文,核对步骤 + 预期是否真的在验那条源的语义,而不是验了一个相近但不同的东西。
  • 回源对账要双向(单向查不出"源里有、用例里没有"):① 用例 → 源(上面这条)防测歪 / 防臆造;② 源 → 用例:把源里要求的每一条 AC / FP 逐条落位——它被哪条用例真正验到,指得出用例号才算落位;指不出 = 覆盖缺失。机检只保证 covers: id 闭合、覆盖矩阵有格子,保不了"这条源真被验到"——挂着 id 的空壳用例照样让格子变绿。

③ 用例质量

逐条审用例本身做得对不对:

  • 等价类划分对不对:输入域是否被合理切成有效 / 无效等价类,每类至少一条代表用例,没有把不同等价类混成一条、也没有同一等价类堆冗余。
  • 边界值取真边界:边界用例是否取了下界 / 下界-1 / 上界 / 上界+1(如"5 次锁定"要测第 4 次不锁、第 5 次锁;"金额 1~1000"要测 0 / 1 / 1000 / 1001),而不是随手取个中间值假装测了边界。
  • 预期锚定 rule-0009:预期是否锚到唯一、真实、产出方的信号(跳转 / 持久化状态 / 数据落库 / 真实 DOM 状态),而不是脆弱的 toast 文案、不是模糊的"功能正常 / 支持 X"这类不可判定措辞;成功 / 失败预期是否分开写死、可观察可判定。
  • 牵强 / 空转用例:有没有挂了 covers: 但步骤 + 预期根本验不到那条源的空壳用例;有没有为了凑覆盖而牵强、注释与实际所测不符(rule-0009 红线)。

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.
