k8s-cost

k8s-cost is a skill for Claude Code, Codex from rohitg00/kubectl-mcp-server. It costs 34 tokens per session (1,056 once invoked), scanned A, original, MIT.

A guide for reducing Kubernetes spending by finding unused resources, matching resource limits to actual needs, and examining cluster efficiency. Kubernetes is a system for running and managing containerized applications.

In plain words
What is it for?
Reviewing namespace or cluster costs, finding unused storage, getting resource-sizing suggestions, identifying idle load balancers, and planning capacity.
Why use it?
It helps reveal wasted capacity and oversized resources that increase infrastructure costs without helping applications.

Written for no agent in particular: nothing here depends on one.

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

k8s-cost 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 11d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/find-overprovisioned.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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 Cost Optimization

Cost analysis and optimization using kubectl-mcp-server's cost tools.

When to Apply

Use this skill when:

  • User mentions: "cost", "savings", "optimize", "expensive", "budget"
  • Operations: cost analysis, right-sizing, cleanup unused resources
  • Keywords: "how much", "reduce", "efficiency", "waste", "overprovisioned"

Priority Rules

Priority Rule Impact Tools
1 Find and delete unused PVCs CRITICAL find_orphaned_pvcs
2 Right-size overprovisioned pods HIGH get_resource_recommendations
3 Identify idle LoadBalancers HIGH get_services
4 Scale down non-prod off-hours MEDIUM scale_deployment
5 Consolidate small namespaces LOW Analysis

Quick Reference

Resource Right-Sizing

get_pod_metrics(name, namespace)

Cost Optimization Workflow

1. Identify Overprovisioned Resources

get_resource_recommendations(namespace="production")

get_pod_metrics(name, namespace)
get_resource_usage(namespace)

2. Find Idle Resources

find_orphaned_pvcs(namespace)

find_unused_resources(namespace)

3. Analyze Node Utilization

get_nodes()
get_node_metrics()

Right-Sizing Guidelines

Current State Recommendation
CPU usage < 10% of request Reduce request by 50%
CPU usage > 80% of request Increase request by 25%
Memory < 50% of request Reduce request
Memory near limit Increase limit, monitor OOM

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.
