What it does

Docker is an agent skill from bobmatnyc/claude-mpm. Docker containerization for packaging applications with dependencies into isolated, portable units ensuring consistency across development, testing, and production environments.

Its SKILL.md is about 7.4k tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files (for example `.etag_cache.json` and `metadata.json`).

It sits in DevOps & Cloud, covering Containers. It works with Docker. The repository describes itself as: Claude Multi-Agent Project Manager — multi-channel orchestration, GitHub-first SDK mode, and plugin system for Claude.

When your agent uses it

Tasks that involve Containers

Example prompts

“/docker”

Requirements

Python 3
Node.js
Docker

Workflow steps

3 steps, taken from the step headings in SKILL.md.

Create Dockerfile
Build Image
Run Container

What it can do on your machine

Read from SKILL.md and the folder at commit 25203d3. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
- docker
- docker-compose
- python
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use docker, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names these keys or tokens, usually read from environment variables:
- POSTGRES_PASSWORD
- MYSQL_ROOT_PASSWORD
- SECRET_KEY
- GITHUB_TOKEN
- CI_REGISTRY_PASSWORD
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Docker loads about 7.4k tokens when it runs. Until then it costs about 46 tokens; SKILL.md has 786 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~46
When it runs · the whole SKILL.md, loaded when a task matches: ~7.4k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check: notes

The automated check noted patterns worth knowing about, such as sudo or a known installer.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 786 words (~7,392 tokens).

“Docker provides containerization for packaging applications with their dependencies into isolated, portable units. Containers ensure consistency across development, testing, and production environments, eliminating "works on my machine" problems.”

Questions about Docker

What does Docker do?

Docker containerization for packaging applications with dependencies into isolated, portable units ensuring consistency across development, testing, and production environments. Docker is an agent skill from bobmatnyc/claude-mpm. Docker containerization for packaging applications with dependencies into isolated, portable units ensuring consistency across development, testing, and production environments.

When should I use Docker?

Docker fits situations like: tasks that involve Containers.

How do I install Docker in Claude Code?

Run `npx skills add bobmatnyc/claude-mpm --skill docker -a claude-code`. Or copy the skill folder (plugin/skills/toolchains-universal-infrastructure-docker in bobmatnyc/claude-mpm) into .claude/skills/docker in your project. Claude Code loads it when a task matches its description.

How do I install Docker in Codex?

Run `npx skills add bobmatnyc/claude-mpm --skill docker -a codex`. Or copy the skill folder (plugin/skills/toolchains-universal-infrastructure-docker in bobmatnyc/claude-mpm) into .agents/skills/docker in your project. Codex loads it when a task matches its description.

Can I use Docker in Cursor, Gemini CLI or GitHub Copilot?

Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add bobmatnyc/claude-mpm --skill docker -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/docker, .gemini/skills/docker, .github/skills/docker and .opencode/skills/docker in your project.

What does Docker need to run?

Going by SKILL.md and its folder, Docker needs the command-line tools its instructions call (docker, docker-compose and python) and credentials named POSTGRES_PASSWORD, MYSQL_ROOT_PASSWORD, SECRET_KEY and GITHUB_TOKEN. Our summary lists: Python 3; Node.js; Docker.

Does Docker access the network?

SKILL.md contains no URLs. Its commands use docker, which can reach the network depending on how they are called. This is read from the text; nothing was executed.

Is Docker safe to install?

Our automated static check of SKILL.md found notes only (mentions a .env file; runs commands with sudo), nothing it rates as a warning. It is not a guarantee. Review the folder before installing.

What licence does Docker use?

Docker has a licence file (the repository's licence) that doesn't match a standard licence. Read it on GitHub before reusing the skill.

How many tokens does Docker use?

About 7.4k tokens (SKILL.md is roughly 30k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.

What are the alternatives to Docker?

Skills that share tags, products or a category with Docker: Iron Proxy Gateway for NanoClaw (nanocoai/nanoclaw, 31k stars), GreptimeDB Dev Docker Image (GreptimeTeam/greptimedb, 6.7k stars), Senior DevOps Toolkit (maslennikov-ig/claude-code-orchestrator-kit, 259 stars) and LangBot Deployment Guide (langbot-app/LangBot, 18k stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.

Who maintains Docker?

bobmatnyc (a GitHub user) maintains it in bobmatnyc/claude-mpm, which has 155 GitHub stars. The repository holds 63 skills in this directory. The repository was last updated on August 31, 2026.
