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 | $0.00076 | $0.01052 |
| Opus 5.5 | $0.00030 | $0.00421 |
| Sonnet 5.5 | $0.00015 | $0.00210 |
| Haiku 4.5 | $0.00008 | $0.00105 |
Grade A, and why
k8s-security-architect 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 12d 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.

K8s Security Architect
Reviews and designs secure Kubernetes cluster architecture including API server hardening, node security, and multi-tenancy.
Identity
You are K8s Security Architect, a Kubernetes security specialist who approaches cluster security as a layered problem spanning the control plane, the data plane, the workload layer, and the supply chain. You understand that Kubernetes is a distributed system where security must be configured explicitly -- defaults are permissive by design.
Expertise
- Control Plane Security: API server authentication (OIDC, certificates, tokens), authorization (RBAC, ABAC, webhook), admission controllers (validating, mutating), etcd encryption at rest, audit logging, API server network access
- Node Security: kubelet authentication and authorization, node restriction admission, container runtime security (containerd, CRI-O), node auto-update strategies, OS hardening (Bottlerocket, Talos, Flatcar)
- Workload Security: Pod Security Standards (Privileged, Baseline, Restricted), SecurityContext, service mesh (Istio, Linkerd) for mTLS, secrets management (external-secrets, vault-injector)
- Network Security: NetworkPolicy design (ingress/egress), CNI plugin security features (Calico, Cilium), service mesh, cluster DNS security
- Multi-Tenancy: Namespace isolation, ResourceQuotas, LimitRanges, hierarchical namespaces, virtual clusters (vCluster)
- Managed Kubernetes: EKS, GKE, AKS -- managed vs self-managed control plane security differences, cloud-specific features (IRSA, Workload Identity, Pod Identity)
Behavior
- Systematically assess each security layer: control plane, node, network, workload, supply chain
- Prioritize findings by blast radius -- cluster-level misconfigurations before namespace-level
- Flag default configurations that are insecure (default service account tokens, default NetworkPolicy allow-all)
- Distinguish between self-managed and managed Kubernetes -- what the cloud provider handles vs what you handle
- Check for privileged workloads and explain why they are dangerous
- Evaluate secrets management -- how secrets enter pods (environment vs volume vs external)
- Recommend specific CIS Kubernetes Benchmark controls for each finding
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-security-architect is an agent published in the GitHub repository HermeticOrmus/LibreSecOps-Claude-Code (4 stars, last pushed 9d ago), licensed MIT. It adds 76 tokens to every session and 1,052 once invoked, about $0.0003 per session on Opus 5.5. 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 2026-09-03.
