api-reviewer

api-reviewer is a command for Claude Code from TestAny-io/testany-agent-skills. It costs 12 tokens per session (539 once invoked), scanned A, original, MIT.

A review process for an API contract, the document that defines how software components communicate. It checks whether the contract matches the product requirements and covers protocol, compatibility, versioning, and error behavior.

In plain words
What is it for?
Use it to review an API contract together with its Product Requirements Document (PRD), identify issues, and produce a review report or approval certificate.
Why use it?
It catches missing details, conflicting changes, and differences between requirements and the planned interface before implementation begins.

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

api-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 1mo 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

API Reviewer

执行前读取 工作流执行约定:先取证再提问、按实际工具能力回退,并从本次安装位置定位资源。

启动 API Contract 评审流程。作为进入 HLD/LLD/实现前的门禁,检测 PRD→Contract 漂移与契约完整性。 评审先读取 证据、准出与复审规则。P2 不按数量阻断;缺证据不等于产品缺陷;提前门禁失败不取消独立安全检查;完成本轮评审不等于批准工件。

先区分 formal_design 与 bounded_change/amendment;有限增量使用既有有效基线及 Owner 批准,只处理受影响范围,不回补全生命周期文档。详见 ../references/document-amendments.md;完整流程只适用于正式新功能/全量准出。

使用方式

提供文档路径:

$ARGUMENTS

API 审查在研发流程中的位置

PRD → API Writer → API Contract → [API Reviewer] → HLD/LLD/实现

审查框架

采用四道门审查:

  1. Gate 1 - 基线与覆盖:PRD 基线、范围/所有权、映射覆盖率
  2. Gate 2 - 协议完整性:各协议必填项检查
  3. Gate 3 - 漂移与冲突:PRD 漂移、重复造轮子、兼容冲突
  4. Gate 4 - 兼容性与演进:版本策略、破坏性变更、幂等与错误语义

准出门槛

  • P0 = 0(任一 P0 即阻断)
  • P1 = 0(任一 P1 即不通过)
  • P2 不按数量阻断

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 Contract 路径开始评审。建议同时提供 PRD 和 Index(如为多协议)。

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.
