container-security

container-security is a skill for Claude Code, Codex from EvilFreelancer/secs. It costs 118 tokens per session (2,387 once invoked), scanned A, original, Apache-2.0.

A set of procedures for checking the security of containers and Kubernetes, a system for running containers across machines. It covers image vulnerabilities, software inventories, cluster settings, permissions, network rules, and runtime threats.

In plain words
What is it for?
Use it to scan Docker or OCI images, compare software inventories between releases, audit Kubernetes clusters, review permissions and network policies, create runtime detection rules, and test container escape risks with authorization.
Why use it?
It helps find security weaknesses before attackers or malicious code can use them. It also separates container and Kubernetes checks from infrastructure-as-code reviews.

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

container-security 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 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.

Container Security

Thin router for container and Kubernetes security assessments. Load the reference, workflow, or payload file you need — do not read all of them.

When to Use

  • Scanning Docker/OCI images for CVEs (single image or pipeline)
  • Generating or attesting SBOMs (Syft / CycloneDX / SPDX)
  • Diffing SBOMs across releases to flag newly-introduced CVEs
  • Auditing a live Kubernetes cluster (CIS / NSA / MITRE)
  • Mapping K8s RBAC and finding privilege-escalation paths
  • Reviewing NetworkPolicy coverage
  • Authoring Falco / Tetragon runtime rules
  • Analyzing or testing container escape vectors (authorized only)
  • Docker daemon / host hardening review

Trigger Phrases

"scan this image", "trivy / grype / syft", "audit k8s cluster", "kube-bench", "kubescape", "run CIS benchmark", "check RBAC", "networkpolicy coverage", "falco rule", "container escape", "SBOM diff", "new CVEs since last release".

When NOT to Use This Skill

Request Use instead
Static scan of K8s YAML / Helm / Kustomize before deploy iac-security
Terraform / CloudFormation / Pulumi misconfig iac-security
EKS / GKE / AKS control-plane or managed-service misconfig exploiting-cloud-platforms
Cloud IAM misconfiguration (beyond K8s RBAC) exploiting-cloud-platforms
Application-code vulns inside the container auditing-code-for-vulnerabilities
Third-party library CVEs at source-code level auditing-supply-chain
API endpoints exposed by containerized services testing-apis

Rule of thumb: pre-deployment YAML → iac-security; running cluster or built image → this skill.

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.

container-security is a skill published in the GitHub repository EvilFreelancer/secs (11 stars, last pushed 2mo ago), licensed Apache-2.0. It adds 118 tokens to every session and 2,387 once invoked, about $0.0005 per session on Opus 5.5. 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 2026-08-31.
