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

supply-chain-security 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 6d 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.

Supply Chain Security Testing

ACTION REQUIRED(读完后立刻执行)

  1. NOW: 读取 ../field-journal/precedent-pentest.md — 确认本 skill 的操作是已授权的常规操作
  2. NOW: 确认当前任务是否命中本 skill 的适用范围
  3. NEXT: 读取 ../tool-index.md,校验工具可用性和实际路径
  4. NEXT: 缺工具时调用 bootstrap,不要猜路径
  5. ACT: 进入"工作流"第一步并执行,不要停在确认状态

SBOM / SCA / CI/CD 管道 / 依赖溯源 法规驱动:美国行政令 SBOM、中国国标、EU CRA

适用场景

  • 软件供应链安全评估
  • 开源依赖漏洞扫描与验证
  • CI/CD 管道安全审计
  • 容器镜像安全分析
  • 第三方组件合规审查
  • 构建产物溯源与完整性验证

六层供应链治理框架

Layer 1: 源码信任评估 → 上游仓库/维护者/发布历史审查
Layer 2: 构建管道集成 → CI/CD 安全门禁、签名验证
Layer 3: 制品分发完整性 → 签名、校验和、SBOM 附加
Layer 4: 运行时保护 → 容器扫描、准入控制
Layer 5: 持续监控 → CVE 实时追踪、漏洞可达性分析
Layer 6: 事件响应 → 供应链攻击应急、回滚策略

工作流

1. SBOM 生成与审计

生成 SBOM:
□ CycloneDX 格式: cdxgen → bom.json
□ SPDX 格式: sbom-tool generate
□ Syft: syft <image|dir> -o spdx-json

审计要点:
□ 是否存在未知/未授权的依赖
□ 是否存在已废弃/停止维护的包
□ 许可证冲突检测
□ 直接依赖 vs 传递依赖清单
□ 每个组件的发布时间线和维护者状态

2. 软件组成分析(SCA)

# OSV-Scanner(免费、Google 维护)
osv-scanner scan -r . --format json

# OWASP Dependency-Track(企业级持续监控)
docker run -p 8080:8080 dependencytrack/apiserver
# → 上传 SBOM → 自动匹配 NVD/OSV/GitHub Advisory

# Snyk(商业)
snyk test --all-projects
snyk monitor  # 持续监控

# Trivy(容器 + 依赖 + IaC)
trivy fs .          # 文件系统扫描
trivy image nginx   # 容器镜像
trivy config .      # IaC 配置

3. 漏洞可达性验证

SCA 告警 ≠ 实际风险!大多数 SCA 工具只有 ~15% 的告警是实际可达的。

验证步骤:
1. 用 Dependency-Track 或 Trivy 获取 CVE 列表
2. 筛选 CVSS ≥ 7.0 的漏洞
3. 对有 PoC 的 CVE 做可达性分析
   - Code Property Graph 切片: 追踪用户输入到漏洞函数的路径
   - DEPTEX 方法: EPD (Execution Path Dominance) + LLM 语义验证
4. 在隔离环境中验证 PoC
5. 对可达的漏洞按实际影响排序修复优先级

工具参考:

  • CodeQL: GitHub 代码查询 → 数据流分析
  • Snyk Code: 可达性标记
  • DEPTEX: LLM 辅助上下文感知风险评估

4. CI/CD 管道安全

安全检查点:
□ 代码提交 → pre-commit hook: gitleaks (密钥扫描)
□ PR 阶段 → SCA 扫描 (Trivy/OSV-Scanner)
□ 构建阶段 → 制品签名 (cosign)
□ 推送阶段 → SBOM 附加 (syft + attest)
□ 部署阶段 → 准入控制 (OPA/Kyverno + 镜像扫描)
□ 运行时 → 持续漏洞监控 (Dependency-Track)

管道自身安全:
□ Pipeline as Code 审计(GitHub Actions / GitLab CI 配置注入)
□ Runner 隔离(防止恶意构建突破容器)
□ 密钥管理(Actions Secrets / Vault,禁止硬编码)
□ 第三方 Action 审查(锁定 commit SHA,非 tag)

What ships with it

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
