prototype-reviewer

prototype-reviewer is a command for Claude Code from TestAny-io/testany-agent-skills. It costs 15 tokens per session (486 once invoked), scanned A, original, MIT.

A command for reviewing an interactive prototype before it moves into API design and high-level technical design. It checks that the prototype matches the requirements and user journeys, covers important states, and stays isolated from production files.

In plain words
What is it for?
Use it to review a prototype sandbox against a product requirements document and user journey, check normal and error states, and produce a pass certificate when it meets the stated thresholds.
Why use it?
It catches missing screens, broken paths, unsafe changes, and weak handoff information before implementation begins. Findings are recorded as evidence in a review report.

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

prototype-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 8d 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

Prototype Reviewer

启动原型审查流程。作为 prototype 进入 API Contract / HLD 阶段前的独立门禁,审查交互正确性、工程隔离安全性和下游输入质量。

使用方式

提供原型沙箱目录路径(建议同时提供 PRD 和 User Journey 路径):

$ARGUMENTS

原型审查在研发流程中的位置

PRD → UC Journey → Prototype Designer → [Prototype Reviewer] → API Contract → HLD

四道门审查框架

第一道门:上游对齐(P0 阻塞)

  • PRD 需求(REQ-*)是否完整映射到页面
  • Journey 步骤是否完整映射到页面
  • PRD / Journey 齐备性

第二道门:原型完整性

  • P0 Journey Happy Path 可达性
  • 状态矩阵覆盖(正常/加载/空/错误/边界)
  • 跨页面导航完整性
  • P1/P2 预算裁剪合规

第三道门:工程隔离(核心安全检查)

  • 沙箱目录完整性
  • 沙箱外零未授权变更
  • 路由前缀隔离
  • 零依赖新增
  • 零生产文件改动

第四道门:下游可用性

  • API Contract 输入质量(数据需求、字段、结构)
  • HLD 输入质量(状态管理、缓存、性能)

准出门槛

  • P0 = 0(任一 P0 即阻断)
  • P1 = 0(任一 P1 即不通过)
  • P2 ≤ 2(超过 2 个 P2 不通过)

必需产出

  • 审查报告(含问题清单和证据)
  • 准出证书(通过时)

请提供沙箱目录路径开始审查。建议同时提供 PRD 和 User Journey 路径。

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.

prototype-reviewer is a command published in the GitHub repository TestAny-io/testany-agent-skills (81 stars, last pushed 11d ago), licensed MIT. It adds 15 tokens to every session and 486 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
