Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00034 | $0.01512 |
| Opus 5.5 | $0.00014 | $0.00605 |
| Sonnet 5.5 | $0.00007 | $0.00302 |
| Haiku 4.5 | $0.00003 | $0.00151 |
Grade A, and why
kubernetes-specialist scanned grade A with 0 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 1mo 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.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Kubernetes Specialist
触发条件
- 需要部署新的微服务到 Kubernetes 集群时。
- 现有 Pod 出现故障、重启或性能瓶颈(如 CPU/Memory 限制)时。
- 需要设计或维护 Helm Charts 以实现应用的参数化部署。
- 配置集群自动扩缩容(HPA/VPA)以应对流量波动。
- 实施 RBAC 权限控制,确保多租户环境的安全。
- 进行集群范围的资源审计或配置优化(ConfigMap/Secret 管理)。
核心能力
1. 资源管理 (Resource Management)
- Deployment: 理解声明式更新,管理副本集、滚动更新策略(RollingUpdate vs Recreate)。
- Service: 熟练配置 ClusterIP、NodePort、LoadBalancer,理解 Endpoints 机制。
- ConfigMap & Secret: 将配置与代码解耦,理解 Secret 的 base64 编码及其实时挂载特性。
- Volume: 管理 PersistentVolume (PV) 和 PersistentVolumeClaim (PVC),配置持久化存储。
2. Pod 故障排查流程
- Phase 1: 查看状态 -
kubectl get pods确认状态(Pending, Error, CrashLoopBackOff)。 - Phase 2: 详情检查 -
kubectl describe pod <name>查看事件日志(Events),定位调度失败或探针失败原因。 - Phase 3: 日志分析 -
kubectl logs <name> [-c container] [--previous]查看标准输出/错误流。 - Phase 4: 运行时调试 -
kubectl exec -it <name> -- /bin/sh进入容器内部排查(如网络连通性)。 - Phase 5: 临时调试容器 - 使用
kubectl debug注入诊断容器。
3. Helm Chart 最佳实践
- 模板化: 合理使用
{{ .Values.xxx }}提取配置,支持多环境部署(values-dev.yaml, values-prod.yaml)。 - 依赖管理: 使用
Chart.yaml管理子 Chart 依赖。 - Hook 机制: 利用
pre-install,post-upgrade等 Hooks 处理数据库迁移或清理任务。 - 版本控制: 严格遵守 Semantic Versioning,确保 Chart 与应用镜像版本同步。
4. 自动扩缩容 (HPA/VPA)
- HPA (Horizontal Pod Autoscaler): 基于 CPU/内存利用率或自定义指标(Custom Metrics)自动增减副本数。
- VPA (Vertical Pod Autoscaler): 自动调整 Pod 的资源请求(Requests)和限制(Limits)。
- Cluster Autoscaler: 与云厂商集成,自动调整节点池大小。
5. 安全与 RBAC
- Namespace 隔离: 逻辑上划分开发、测试、生产环境。
- RBAC: 定义 Role/ClusterRole 和 RoleBinding/ClusterRoleBinding,遵循最小权限原则。
- Network Policy: 控制 Pod 间的流量出入,实施微服务间的安全隔离。
常用命令/模板
故障排查组合拳
# 查看所有 Namespace 下异常的 Pod
kubectl get pods -A --field-selector=status.phase!=Running
# 追踪实时日志并显示时间戳
kubectl logs -f <pod-name> --timestamps
# 查看资源占用排行
kubectl top nodes
kubectl top pods
# 导出资源定义的干净版本(去除 runtime 信息)
kubectl get deployment <name> -o yaml | kubectl-neat > deployment.yaml

replicas: 3

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.
- 1mo ago First seen · 142 lines · 34 tokens per session scan A e41b625752f3
kubernetes-specialist is a skill published in the GitHub repository seaworld008/Commonly-used-high-value-skills (73 stars, last pushed yesterday), licensed MIT. It adds 34 tokens to every session and 1,512 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
