docker

docker is a skill for Claude Code, Codex from gebruder/wirken. It costs 5 tokens per session (293 once invoked), scanned A, original, MIT.

A guide to Docker, a system for running applications in isolated containers. It covers containers, images, Dockerfiles, Docker Compose, logs, inspection, and cleanup.

In plain words
What is it for?
Use it to run and inspect containers, view logs, execute commands inside containers, build or remove images, operate Compose projects, and check Docker disk usage.
Why use it?
It helps manage the common tasks involved in starting, stopping, debugging, building, and cleaning up containerized applications.

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

docker 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 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.

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.

What it actually says

Docker

Manage Docker containers and images.

Containers

  • List running: docker ps
  • List all: docker ps -a
  • Run: docker run -d --name <name> <image>
  • Stop: docker stop <name>
  • Remove: docker rm <name>
  • Logs: docker logs <name> --tail 50
  • Exec into: docker exec -it <name> sh
  • Inspect: docker inspect <name> | jq '.[0].State'

Images

  • List: docker images
  • Pull: docker pull <image>
  • Build: docker build -t <tag> .
  • Remove: docker rmi <image>

Compose

  • Start: docker compose up -d
  • Stop: docker compose down
  • Logs: docker compose logs --tail 50
  • Status: docker compose ps

Cleanup

  • Remove stopped containers: docker container prune -f
  • Remove unused images: docker image prune -f
  • Disk usage: docker system df
Changes

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.
