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 | $0.01056 |
| Opus 5 | $0.00017 | $0.00528 |
| Sonnet 5 | $0.00007 | $0.00211 |
| Haiku 4.5 | $0.00003 | $0.00106 |
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.
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.
How it starts
The opening of the file, as written. The whole thing — 174 lines — stays where its author put it; the contents beside it link to each section on GitHub.
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
| Task | Tool | Example |
|---|---|---|
| Namespace cost | get_namespace_cost |
get_namespace_cost(namespace) |
| Cluster cost | get_cluster_cost |
get_cluster_cost() |
| Unused PVCs | find_orphaned_pvcs |
find_orphaned_pvcs(namespace) |
| Right-sizing | get_resource_recommendations |
get_resource_recommendations(namespace) |
Quick Cost Analysis
Get Cost Summary
get_namespace_cost(namespace)
get_cluster_cost()
Find Unused Resources
find_unused_resources(namespace)
find_orphaned_pvcs(namespace)
Resource Right-Sizing
get_resource_recommendations(namespace)
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 ships with it
1 file 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.
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.

k8s-cost is a skill published in the GitHub repository rohitg00/kubectl-mcp-server (956 stars, last pushed 5mo ago), licensed MIT. It adds 34 tokens to every session and 1,056 once invoked, about $0.0002 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 2026-08-30.
