Docker Compose

What it does

When your agent uses it

• Unrelated requests
• Route to the nearest named specialist

Example prompts

• “/docker-compose”

Requirements

• A Bash shell
• Docker
• Compatibility (from SKILL.md): Docker Compose v2 or another implementation of the Compose Specification; commands require Docker CLI.

Workflow steps

6 steps, taken from the first numbered list in SKILL.md.

1. 1Discover the Compose file(s), project directory, env files, profiles, external resources, and whether the task is development, CI…
2. 2Model the application with services, named volumes for durable state, explicit networks for isolation, secrets for sensitive files, and…
3. 3Resolve before running
4. 4Operate with the narrowest command: up -d SERVICE, restart SERVICE, run --rm SERVICE COMMAND, or exec SERVICE COMMAND. Avoid down -v…
5. 5Verify with ps, health status, logs, an in-container check, and the externally published endpoint where applicable.
6. 6Diagnose in order: resolved model → container state → logs → healthcheck → network membership/DNS → mounts/permissions → image/build…

What it can do on your machine

Read from SKILL.md and the folder at commit 96fbe07. 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

  Ships 1 file in scripts/ (Shell, from the files we listed), which the agent can run.

  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.

• Compatibility

  Docker Compose v2 or another implementation of the Compose Specification; commands require Docker CLI.

  From compatibility in the SKILL.md frontmatter.

Context cost

Docker Compose loads about 2k tokens when it runs, and up to ~6.2k if it reads all its reference files. Until then it costs about 79 tokens; SKILL.md has 782 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it

~79

When it runs · the whole SKILL.md, loaded when a task matches

~2k

With references · SKILL.md plus every file in references/, read only if the agent opens them

~6.2k

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

• NoteMentions a .env fileSKILL.md:41

  -env-file`, which overrides the project `.env`; use `${REQUIRED:?explain}` for mandatory values and `$$` for a literal d

• NoteMentions a .env fileSKILL.md:100

  | `.env`, interpolation, profiles, or overrides | `references/04-configuration-and-overrides.md` |

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); the scripts in this folder are not scanned.

docker-compose

description

Use Docker Compose to define, run, debug, and harden multi-container applications. Load for compose.yaml design, networking, volumes, secrets, profiles, overrides, watch mode, lifecycle operations, or troubleshooting. Do not use this skill for unrelated requests; route to the nearest named specialist.
