What it does

Docker Test is an agent skill from rojopolis/spellcheck-github-actions. Build the Docker image as :local and run the full Bats test suite

Its SKILL.md is about 150 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in DevOps & Cloud, covering Containers and Test generation. It works with Docker. The licence is MIT.

When your agent uses it

  • Tasks that involve Containers
  • Tasks that involve Test generation

Example prompts

  • “/docker-test”

Requirements

  • Docker

Workflow steps

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

  1. Build the local Docker image
  2. Run all Bats tests against the local image
  3. Report which tests passed or failed. If the Docker build failed, show the build error before proceeding.

What it can do on your machine

Read from SKILL.md and the folder at commit 40f18c3. 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 Test loads about 148 tokens when it runs. Until then it costs about 19 tokens; SKILL.md has 50 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~19
When it runs · the whole SKILL.md, loaded when a task matches
~148

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 passed

The automated check found no risky patterns in SKILL.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); files beside SKILL.md are not scanned.

Run the full test cycle for the spellcheck action:

  1. Build the local Docker image:

    bash
    docker build -t jonasbn/github-action-spellcheck:local .
  2. Run all Bats tests against the local image:

    bash
    bats test/test.bats
  3. Report which tests passed or failed. If the Docker build failed, show the build error before proceeding.

To run a single test by name, use:

bash
bats --filter "<test name>" test/test.bats
