team-threat-model

team-threat-model is a skill for Claude Code from ketor/cto-fleet. It costs 142 tokens per session (9,338 once invoked), scanned A, original, Apache-2.0.

An automated security review team that maps a system, identifies possible threats, rates their risk, and writes a security plan.

In plain words
What is it for?
Use it to review a whole system, a specific component, or an API, then produce a threat model and prioritized fixes using STRIDE and DREAD methods.
Why use it?
It helps organize security analysis when a project has many components and possible attack paths.

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

team-threat-model scanned grade A 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 9d 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 rootlowPrivilege 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}`)

Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.

How it starts

The opening of the file, as written. The whole thing — 656 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)
  • --framework=stride|dread|both:威胁建模框架(可选,默认 both
  • --scope=system|component|api:建模范围(可选,默认 system
  • --lang=zh|en:输出语言(默认 zh 中文)

解析后将标志从建模需求描述中移除。

建模范围说明

  • system:整体系统威胁建模(架构层面,所有组件和数据流)
  • component:特定组件威胁建模(聚焦指定模块/服务的内部威胁)
  • api:API 层面威胁建模(聚焦 API 端点的攻击面分析)
模式 用户确认范围 条件节点处理
标准模式(默认) 建模范围确认 + 最终报告确认 正常询问用户
单轮确认模式--once 仅最终报告确认 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:

  • 威胁分类不确定 → 对应 modeler 自行判断,报告中说明
  • 两位 modeler 对同一威胁的风险评级差异过大(DREAD 评分差 ≥ 3)不可跳过,必须暂停问用户(熔断机制)
  • 高危(Critical)威胁超过 10 个不可跳过,必须暂停问用户(熔断机制)
  • 架构信息不完整(缺少部署拓扑) → scanner 标注"信息不完整",基于可用信息建模
  • 威胁数量超出预期(> 50 个) → assessor 自行决定是否分组聚合

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(评级差异过大、高危威胁超过 10 个时仍必须暂停问用户)。

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