What it does
Docker is an agent skill from OpenHands/extensions. Run Docker commands within a container environment, including starting the Docker daemon and managing containers. Use when building, running, or managing Docker containers and images.
Its SKILL.md is about 230 tokens, which your agent loads only when the skill is triggered. The skill folder holds 5 other files (for example `.plugin/plugin.json` and `README.md`).
It sits in DevOps & Cloud, covering Containers. It works with Docker. The repository describes itself as: Public registry for OpenHands extensions. The licence is MIT.
When your agent uses it
- Managing Docker containers and images
- Tasks that involve Containers
Example prompts
- “/docker”
Requirements
- Docker
What it can do on your machine
Read from SKILL.md and the folder at commit d008b81. 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
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 no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Docker loads about 231 tokens when it runs. Until then it costs about 48 tokens; SKILL.md has 69 words of instructions outside code blocks.
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.
- NoteRuns commands with sudoSKILL.md:17
sudo dockerd > /tmp/docker.log 2>&1 & - NoteRuns commands with sudoSKILL.md:23
r the Docker service instead of running `sudo dockerd`; then run Docker commands from PowerShell without `sudo`. - NoteRuns commands with sudoSKILL.md:30
sudo docker run hello-world
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.

Docker Usage Guide
Starting Docker in Container Environments
Please check if docker is already installed. If so, to start Docker in a container environment:
# Start Docker daemon in the background
sudo dockerd > /tmp/docker.log 2>&1 &
# Wait for Docker to initialize
sleep 5On Windows, start Docker Desktop or the Docker service instead of running sudo dockerd; then run Docker commands from PowerShell without sudo.
Verifying Docker Installation
To verify Docker is working correctly, run the hello-world container:
sudo docker run hello-worldPowerShell equivalent after Docker Desktop is running: docker run hello-world.

When should I use Docker?
Docker fits situations like: managing Docker containers and images; tasks that involve Containers.
How do I install Docker in Claude Code?
Run `npx skills add OpenHands/extensions --skill docker -a claude-code`. Or copy the skill folder (skills/docker in OpenHands/extensions) 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 OpenHands/extensions --skill docker -a codex`. Or copy the skill folder (skills/docker in OpenHands/extensions) 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 OpenHands/extensions --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). Our summary lists: 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 (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 is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
How many tokens does Docker use?
About 231 tokens (SKILL.md is roughly 924 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.
