docker

docker is a skill for Claude Code, Codex from wpank/ai. It costs 98 tokens per session (2,492 once invoked), scanned A, original, no licence file.

Guidance for packaging applications in Docker containers, which bundle software with the files it needs to run. It covers Dockerfiles, Docker Compose, image size, security, networking, and deployment.

In plain words
What is it for?
Use it to improve Dockerfiles, reduce image size, harden container security, configure networks, set up Docker Compose, or prepare containers for production.
Why use it?
It helps address common container problems, such as oversized images, unsafe settings, networking errors, and difficult multi-container setups. Docker Compose is a tool for defining and running several related containers together.

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 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 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.

Asks for rootlowPrivilege escalation

A mod that escalates privileges can change anything on the machine, not only the project.

- **NEVER run as root** - Create and use non-root users with specific UID/GID

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

Makes network callslowCapability

Not a fault in itself. Listed so you know the mod talks to something, and to what.

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.

docker is a skill published in the GitHub repository wpank/ai (12 stars, last pushed 8mo ago), with no licence file. It adds 98 tokens to every session and 2,492 once invoked, about $0.0004 per session on Opus 5.5. A static security scan graded it A with 2 findings (asks for root, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
