team-contract-test

team-contract-test is a skill for Claude Code from ketor/cto-fleet. It costs 139 tokens per session (8,459 once invoked), scanned B, original, Apache-2.0.

A coordinated process for creating API contract tests. An API contract is the agreed shape and behaviour of communication between software services.

In plain words
What is it for?
Reading OpenAPI, gRPC, or Pact definitions, generating provider and consumer contract tests, and checking compatibility.
Why use it?
It checks whether a service still matches what its users or other services expect and helps detect breaking changes early.

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 B, and why

team-contract-test scanned grade B with 1 finding 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 7d 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.

Asks for rootmediumPrivilege escalation

A mod that escalates privileges can change anything on the machine, not only the project.

How it starts

The opening of the file, as written. The whole thing — 625 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Preamble (run first)

_UPD=$(~/.claude/skills/cto-fleet/bin/cto-fleet-update-check 2>/dev/null || true)
[ -n "$_UPD" ] && echo "$_UPD" || true

If output shows UPGRADE_AVAILABLE <old> <new>: read ~/.claude/skills/cto-fleet/cto-fleet-upgrade/SKILL.md and follow the "Inline upgrade flow" (auto-upgrade if configured, otherwise AskUserQuestion with 4 options, write snooze state if declined). If JUST_UPGRADED <from> <to>: tell user "Running cto-fleet v{to} (just updated!)" and continue.

参数解析:从 $ARGUMENTS 中检测以下标志:

  • --auto:完全自主模式(不询问用户任何问题,全程自动决策)
  • --once:单轮确认模式(将所有需要确认的问题合并为一轮提问,确认后全程自动执行)
  • --style=pact|openapi|grpc|auto:契约风格(可选,默认 auto 自动检测)
  • --scope=provider|consumer|both:测试范围(可选,默认 both
  • --lang=zh|en:输出语言(默认 zh 中文)

解析后将标志从测试需求描述中移除。

契约风格自动检测:当 --style=auto(默认)时,scanner 根据项目特征自动选择:

  • 存在 OpenAPI/Swagger 规范文件(openapi.yamlswagger.json 等)→ openapi
  • 存在 .proto 文件或 gRPC 服务定义 → grpc
  • 存在 Pact 配置或消费者测试 → pact
  • 以上均无 → 基于 HTTP API 端点推断,默认 openapi
模式 用户确认范围 条件节点处理
标准模式(默认) 契约范围确认 + 最终测试套件确认 正常询问用户
单轮确认模式--once 仅最终测试套件确认 自动决策 + 收尾汇总
完全自主模式--auto 不询问用户 全部自动决策,收尾汇总所有决策

单轮确认模式下自动决策规则:

  • API 端点分类不确定 → 对应 designer 自行判断,报告中说明
  • 两位 designer 对同一端点的契约定义冲突(字段类型/必填性不一致)不可跳过,必须暂停问用户(熔断机制)
  • 破坏性变更超过 10 个不可跳过,必须暂停问用户(熔断机制)
  • API 规范文件不存在或解析失败 → scanner 标注"该规范不可用",基于代码推断
  • 端点数量超出预期(> 200 个) → generator 自行决定是否分批生成

完全自主模式下:所有节点均自动决策,不询问用户。熔断机制仍然生效(契约定义冲突、破坏性变更超过 10 个时仍必须暂停问用户)。

使用 TeamCreate 创建 team(名称格式 team-contract-test-{YYYYMMDD-HHmmss},如 team-contract-test-20260308-143022,避免多次调用冲突),你作为 team lead 按以下流程协调。

文件交接规范(File-Based Handoff)

所有 agent 间传递详细报告时,必须采用文件交接模式(防止上下文溢出触发 20MB 限制):

  1. 写入文件:将完整报告写入团队工作目录:
    • 目录路径:/tmp/{team-name}/(team lead 在 TeamCreate 后执行 mkdir -p /tmp/{team-name} && chmod 700 /tmp/{team-name}
    • 单个文件 ≤ 2000 行;超大报告拆分为 summary + details 文件
  2. 发送引用:通过 SendMessage 仅发送(≤500 字符):
    • 文件路径(1 行)
    • 关键摘要(含核心指标/发现/评分)
  3. 按需读取:接收方使用 Read 按需读取文件,发送方不内联完整内容
  4. 路径转发:team lead 转发报告时只转发文件路径 + 摘要,不 Read 后再 SendMessage
  5. 遵从校验:team lead 收到超 1000 字符且不含 /tmp/team- 路径前缀的消息时,要求 agent 以文件交接模式重发

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.
