team-api-design

team-api-design is a skill for Claude Code, Codex from ketor/cto-fleet. It costs 113 tokens per session (7,401 once invoked), scanned B, original, Apache-2.0.

A guided team process for turning API requirements into a design and standard schema. An API is the defined way that software systems exchange requests and data; the output can use REST, gRPC, or GraphQL formats.

In plain words
What is it for?
Use it to design a new API and generate OpenAPI, Protobuf, or GraphQL Schema documentation. It can also account for compatibility constraints in an existing API and produce Chinese or English output.
Why use it?
It reduces uncertainty around endpoint or message design and helps catch incompatible choices before implementation. Independent designs and expert review expose disagreements and document the final decision.

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-api-design scanned grade B with 2 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 5d 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.

- 目录路径:`/tmp/{team-name}/`(team lead 在 TeamCreate 后执行 `mkdir -p /tmp/{team-name} && chmod 700 /tmp/{team-name}`)

Not a fault in itself. Listed so you know the mod talks to something, and to what.

How it starts

The opening of the file, as written. The whole thing — 574 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=rest|grpc|graphql:API 风格(默认 rest
  • --lang=zh|en:输出语言(默认 zh 中文)

解析后将标志从 API 需求描述中移除。

模式 用户确认范围 条件节点处理
标准模式(默认) 需求确认 + 设计分歧仲裁 + 评审结果确认 + 最终文档确认 正常询问用户
单轮确认模式--once 仅最终文档确认 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

单轮确认模式下条件节点自动决策规则:

  • API 风格不确定 → team lead 根据项目特征自行判断,在最终文档中说明
  • 两位 designer 分歧 → reviewer 标注分歧,team lead 综合论证后裁决,收尾时汇总
  • 分歧超过 50%不可跳过,必须暂停问用户(熔断机制)
  • reviewer 否决设计不可跳过,必须暂停问用户(熔断机制)
  • 现有 API 存在兼容性约束 → researcher 识别约束条件,designer 在设计中保持兼容
  • --style 参数处理:如果用户指定了 --style,所有设计和文档按指定风格输出;未指定时 team lead 根据项目技术栈推断

完全自主模式下:所有节点均自动决策,不询问用户。仅熔断机制(分歧超过 50%、reviewer 否决设计)仍然生效,触发时必须暂停。

使用 TeamCreate 创建 team(名称格式 team-api-design-{YYYYMMDD-HHmmss},如 team-api-design-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.
