k8sc-platform is a cursor rule for Cursor from sfc-gh-cconner/support-rules-mcp. It costs 947 tokens per session, scanned A, original, Apache-2.0.

Kubernetes platform configuration for cluster add-ons, platform overlays, and ingress controllers used with SPCS. It is organized in a GitHub repository and includes patterns for ArgoCD, Kustomize, networking, certificates, and DNS.

In plain words
What is it for?
Use it to inspect or update ArgoCD applications, Kustomize overlays, ingress controllers, certificate management, external DNS, Calico networking, and CoreDNS configuration.
Why use it?
It helps developers find and work with the shared configuration that adds platform services to Kubernetes clusters. It also gives them known search patterns for locating specific components.

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

k8sc-platform 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.
