container-audit

container-audit is a skill for Claude Code, Codex from greglas75/zuvo. It costs 225 tokens per session (6,929 once invoked), scanned B, original, MIT.

A read-only security review of Dockerfiles, container files, and Docker Compose configurations. It checks how container images are built and run for common security problems.

In plain words
What is it for?
Use it to review container setup before deployment, after editing Docker or Compose files, or during regular security checks. It also checks known software vulnerabilities and unnecessary image contents.
Why use it?
It helps find unsafe settings before a containerized service is shipped, such as running as root, using changeable base images, storing secrets in image layers, or exposing the Docker socket.

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 B, and why

container-audit scanned grade B with 2 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 3d 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.

Recursive force deletemediumDestructive command

rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

| Package-manager cache | `--no-cache` / `rm -rf /var/lib/apt/lists` | apt/apk cache left in a layer | MEDIUM |

Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.

How it starts

The opening of the file, as written. The whole thing — 513 lines — stays where its author put it; the contents beside it link to each section on GitHub.

zuvo:container-audit

Audit container artifacts (Dockerfile, Containerfile, docker-compose) as code for security defects — running as root, mutable :latest bases, secrets baked into layers, bloated attack surface, known CVEs, and docker.sock mounts. Single-pass, read-only.

When to use: before shipping a Dockerized service, after editing a Dockerfile or compose file, periodic container hardening review, pre-deploy gate. When NOT to use: auditing the live Docker daemon on a remote host over SSH (zuvo:infra-audit IS9); Docker build speed / cache in CI (zuvo:ci-audit CI8); application-code vulnerabilities (zuvo:security-audit).

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.

container-audit is a skill published in the GitHub repository greglas75/zuvo (6 stars, last pushed today), licensed MIT. It adds 225 tokens to every session and 6,929 once invoked, about $0.0011 per session on Opus 5. A static security scan graded it B with 2 findings (recursive force delete, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
