What it does

Run Tests is an agent skill from Microck/ordinary-claude-skills. Validate code changes by intelligently selecting and running the appropriate test suites. Use this when editing code to verify changes work correctly, run tests, validate functionality, or check for regressions. Automatically discovers affected test suites, selects the minimal set of venvs needed for validation, and handles test execution with Docker services as needed.

Its SKILL.md is about 3k tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file (for example `metadata.json`).

It sits in Testing & QA, covering Test generation. It works with Docker. The repository describes itself as: An unappealing collection of Claude Skills and resources.

When your agent uses it

  • Tasks that involve Test generation

Example prompts

  • “/run-tests”

Requirements

  • Python 3
  • Docker
  • Pre-approved tools (allowed-tools): Bash, Read, Grep, Glob, TodoWrite

Workflow steps

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

  1. Identify Changed Files
  2. Discover Available Test Suites
  3. Intelligently Select Venvs
  4. Execute Selected Venvs
  5. Handle Results

What it can do on your machine

Read from SKILL.md and the folder at commit 1056d29. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves these tools, so the agent can use them without asking each time:

    • Bash
    • Read
    • Grep
    • Glob
    • TodoWrite

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • docker
    • git

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use docker and git, 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

Run Tests loads about 3k tokens when it runs. Until then it costs about 96 tokens; SKILL.md has 1,296 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~96
When it runs · the whole SKILL.md, loaded when a task matches
~3k

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.

  • NotePre-approves every shell command (allowed-tools: Bash)SKILL.md
    allowed-tools: Bash, Read, Grep, Glob, TodoWrite

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 1,296 words (~3,016 tokens).

“This skill helps you efficiently validate code changes by running the appropriate subset of the test suite. It uses scripts/run-tests to intelligently discover affected tests and run only what's necessary for validation.”
