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.

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 | $0.00043 | $0.01820 |
| Opus 5.5 | $0.00017 | $0.00728 |
| Sonnet 5.5 | $0.00009 | $0.00364 |
| Haiku 4.5 | $0.00004 | $0.00182 |
Grade A, and why
k8s-security-policies 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 1mo 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.
This is a copy
88% identical to k8s-security-policies — 14 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

Kubernetes Security Policies
Comprehensive guide for implementing NetworkPolicy, PodSecurityPolicy, RBAC, and Pod Security Standards in Kubernetes.
Purpose
Implement defense-in-depth security for Kubernetes clusters using network policies, pod security standards, and RBAC.
When to Use This Skill
- Implement network segmentation
- Configure pod security standards
- Set up RBAC for least-privilege access
- Create security policies for compliance
- Implement admission control
- Secure multi-tenant clusters
Pod Security Standards
1. Privileged (Unrestricted)
apiVersion: v1
kind: Namespace
metadata:
name: privileged-ns
labels:
pod-security.kubernetes.io/enforce: privileged
pod-security.kubernetes.io/audit: privileged
pod-security.kubernetes.io/warn: privileged
2. Baseline (Minimally restrictive)
apiVersion: v1
kind: Namespace
metadata:
name: baseline-ns
labels:
pod-security.kubernetes.io/enforce: baseline
pod-security.kubernetes.io/audit: baseline
pod-security.kubernetes.io/warn: baseline
3. Restricted (Most restrictive)
apiVersion: v1
kind: Namespace
metadata:
name: restricted-ns
labels:
pod-security.kubernetes.io/enforce: restricted
pod-security.kubernetes.io/audit: restricted
pod-security.kubernetes.io/warn: restricted
Network Policies
Default Deny All
apiVersion: networking.k8s.io/v1
kind: NetworkPolicy
metadata:
name: default-deny-all
namespace: production
spec:
podSelector: {}
policyTypes:
- Ingress
- Egress
Allow Frontend to Backend
apiVersion: networking.k8s.io/v1
kind: NetworkPolicy
metadata:

matchLabels:
app: backend
policyTypes:

port: 8080
Allow DNS
apiVersion: networking.k8s.io/v1
kind: NetworkPolicy
metadata:
name: allow-dns
namespace: production

What ships with it
2 files 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.
- 1mo ago First seen · 335 lines · 43 tokens per session scan A a2c3f21b667b
k8s-security-policies is a skill published in the GitHub repository HermeticOrmus/LibreUIUX-Claude-Code (115 stars, last pushed 15d ago), licensed MIT. It adds 43 tokens to every session and 1,820 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. It is 88% identical to k8s-security-policies, differing in 14 lines, and is treated as a copy.
