How it fires

How this skill gets triggered: by you, by Claude, or both.

  • Fires itselfAuto-invocation. Claude auto-loads it when your prompt matches the work.Auto-invocation is when the right skill fires by itself at the right moment, driven by a FLOW.md router and a hook, instead of you invoking it by name. It is the difference between a skill being installed and a skill actually getting used.Read the full definition →

Cloud / Container / Kubernetes Security

适用场景

  • 云元数据 SSRF(169.254.169.254 / IMDS)
  • IAM 过度权限、公开存储桶、错误安全组
  • Docker/containerd 逃逸路径评估
  • Kubernetes RBAC、Secrets、Admission、供应链镜像
  • 容器镜像漏洞(可联动 `supply-chain-security/`)

工作流

Phase 1 — 身份与边界

□ 当前身份:云 AK/SK、K8s SA、节点 SSH?
□ 范围:单账号 / 单 cluster / 单 namespace
□ 网络档:authorized_target_only

Phase 2 — 云控制面

# 示例(按厂商替换;MUST 在授权账号内)
aws sts get-caller-identity
aws s3 ls
# Azure / GCP 对应 identity 命令
□ 公开桶 / 错误 ACL
□ 元数据:IMDSv1 vs v2;SSRF 链
□ 角色可扮演(PassRole)与横向

Phase 3 — 容器

□ 是否 privileged / hostPath / hostNetwork
□ capabilities(SYS_ADMIN 等)
□ 可写宿主机路径 → 逃逸候选
□ 镜像历史与已知 CVE → Trivy

Phase 4 — Kubernetes

kubectl auth can-i --list
kubectl get pods,secrets,svc -A
kubectl get clusterrolebindings
□ SA token 挂载与权限
□ 危险 admission webhook 缺失
□ etcd / dashboard 暴露
□ 网络策略是否默认放行
