kubernetes-patterns

kubernetes-patterns is a skill for Claude Code, Codex from cosmicstack-labs/mercury-agent-skills. It costs 24 tokens per session (427 once invoked), scanned A, original, MIT.

A guide to running applications on Kubernetes, a system that schedules containers across a cluster of machines. It covers deployments, networking, permissions, scaling, and production safeguards.

In plain words
What is it for?
Use it to configure workloads, services, ingress routes, autoscaling, health checks, and role-based access control.
Why use it?
It helps keep containerized applications available, reachable, and properly resourced as demand changes. It also reduces common security and reliability mistakes in cluster configuration.

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

kubernetes-patterns 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 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.

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.

What it actually says

Kubernetes Patterns

Deploy and manage production Kubernetes clusters.

Core Objects

Workloads

Object Use Case Scaling
Deployment Stateless apps Replicas, HPA
StatefulSet Stateful apps (DBs) Stable network IDs
DaemonSet Per-node agents (logging, monitoring) Node count
Job/CronJob Batch tasks, scheduled jobs Completion

Networking

  • Service: Stable endpoint for pods (ClusterIP, NodePort, LoadBalancer)
  • Ingress: HTTP routing, TLS termination, path-based routing
  • Network Policies: Pod-level firewall rules

Production Best Practices

Resource Management

resources:
  requests:
    cpu: 100m
    memory: 128Mi
  limits:
    cpu: 500m
    memory: 256Mi
  • Always set requests AND limits
  • Use LimitRange for namespace defaults
  • Use ResourceQuota for namespace caps

Pod Anti-Affinity

Spread pods across nodes for HA.

Readiness & Liveness Probes

  • Readiness: traffic starts flowing
  • Liveness: pod gets restarted
  • Startup: for slow-starting containers

RBAC

  • Least-privilege service accounts per app
  • Namespace-scoped roles (not cluster-wide)
  • Regularly audit permissions
  • Use groups, not individual users

Autoscaling

  • HPA: scale by CPU/memory or custom metrics
  • VPA: adjust resource requests automatically
  • Cluster Autoscaler: add/remove nodes
  • KEDA: event-driven scaling (SQS queue depth, etc.)
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.

kubernetes-patterns is a skill published in the GitHub repository cosmicstack-labs/mercury-agent-skills (471 stars, last pushed 14d ago), licensed MIT. It adds 24 tokens to every session and 427 once invoked, about $0.0001 per session on Opus 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.
