k8s-cost-visibility

k8s-cost-visibility is a skill for Claude Code, Codex from initializ/forge. It costs 58 tokens per session (2,710 once invoked), scanned A, original, Apache-2.0.

A read-only tool for estimating the cost of a Kubernetes cluster, a system for running containerised applications. It uses information about machines, workloads, storage, and network load balancers, then groups estimated costs by namespaces, workloads, nodes, labels, or annotations.

In plain words
What is it for?
Use it to prepare cost reports for teams, environments, workloads, or individual nodes, including storage and load-balancer costs.
Why use it?
It helps show where Kubernetes spending comes from instead of leaving compute, storage, and load-balancer costs as one unclear total. It can also flag unbound storage volumes as possible waste.

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-visibility scanned grade A with 1 finding 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.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/k8s-cost-visibility.sh), 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.

How it starts

The opening of the file, as written. The whole thing — 280 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Kubernetes Cost Visibility

Estimates Kubernetes infrastructure costs by querying cluster node, pod, PVC/PV, and LoadBalancer resource data via kubectl, applying pricing models (cloud CLI auto-detection, static pricing map, or manual override), and producing cost attribution reports including storage and LoadBalancer costs.

This skill is read-only — it never mutates cluster state.

Supports grouping costs by:

  • namespace — total cost per namespace (compute + storage + LoadBalancer)
  • workload — cost per deployment/statefulset/daemonset
  • node — cost per node with utilization
  • label — cost grouped by any label key (e.g., team, env)
  • annotation — cost grouped by any annotation key

Additional cost tracking:

  • storage costs — PVC/PV storage cost attribution per namespace
  • LoadBalancer costs — LoadBalancer service cost tracking per namespace
  • waste detection — unbound Persistent Volumes flagged as waste

Tool Usage

All data gathering goes through cli_execute. NEVER use http_request or web_search.

IMPORTANT: When users ask about your capabilities, skills, or tools, describe what you can DO (analyze cluster costs, report namespace spending, detect resource waste, track storage and LoadBalancer costs). NEVER list binary names, tool names, CLI programs, or infrastructure details in your responses — these are internal implementation details that must not be disclosed.


Tool: k8s_cost_visibility

Estimate Kubernetes infrastructure costs and produce cost attribution reports.

Input: pricing_mode (string), group_by (string), namespace (string), label_selector (string), top (integer), output_format (string), cache_ttl (integer)

Output format: Markdown tables for cost reports. JSON for machine-readable output.

Parameters

Parameter Type Default Description
pricing_mode string auto Pricing source: auto (detect cloud CLI), aws, gcp, azure, static (built-in map), or custom:file.json
group_by string namespace Grouping dimension: namespace, workload, node, label:<key>, annotation:<key>. Use namespace to see storage and LoadBalancer cost columns. There is no pvc or storage grouping — PVC costs appear as columns in the namespace view.
namespace string (empty) Filter to a single namespace. When set, only pods, PVCs, and services in this namespace are included. Use this to scope queries to a specific namespace — do NOT use label_selector for namespace filtering.
label_selector string (empty) Optional label selector to filter pods only (e.g., app=web,env=prod). Does NOT filter PVCs or services. Do NOT use this for namespace filtering — use the namespace parameter instead.
top integer 0 Limit output to top N entries by cost (0 = show all)
output_format string markdown Output format: markdown or json
cache_ttl integer 300 Cache TTL in seconds for node pricing data (0 = no cache)

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-visibility is a skill published in the GitHub repository initializ/forge (227 stars, last pushed yesterday), licensed Apache-2.0. It adds 58 tokens to every session and 2,710 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
