test-runner

Skill0 starsChanged 8 months agoMITView on GitHub

Auto-invoke a test runner sub-agent to run tests and diagnose failures. Use when tests need to be run, when debugging test failures, or to verify implementation. Triggers: "run tests", "run the test suite", "check if tests pass", "why is this test failing", after implementing a fix, after completing GREEN phase of TDD, "test this".

The file

We split this skill into the rules it gives an agent

1 rule. 0 are common, 1 is distinctive, and 0 are very specific to this project.

  • 0

    Common

    Most of the 18 edited versions we read keep these.

  • 1

    Distinctive

    This author's own choices. Worth a look.

  • 0

    Very specific

    Tied to their project's names, files or tools. Probably skip.

  • Common
  • Distinctive
  • Very specific
  1. Distinctive:

    If a specific test file was mentioned, pass it as context to the agent.

    line 32

“Common” is measured: kept by at least 6 in 10 of the 18 edited versions of this file we could read. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.

Keep what fits and drop the rest. Your version, ready for your agents.

Test Runner — Sub-agent Workflow

When to use (auto-trigger)

  • After implementing code — verify nothing is broken
  • When debugging a test failure — delegate diagnosis to the sub-agent
  • Before /commit — ensure all tests pass (also handled by /commit quality gate)
  • When switching context — run full suite to check baseline
  • Never as a substitute for TDD — use /tdd for the Red-Green-Refactor cycle

Process

Delegate to the test-runner agent (.claude/agents/test-runner.md):

Use the Agent tool to spawn a test-runner sub-agent with subagent_type="general-purpose"
and model="haiku". The agent prompt is defined in .claude/agents/test-runner.md.

The agent runs tests, parses failures, reads source files, and returns a structured diagnosis. It does NOT fix tests — it reports only.

If a specific test file was mentioned, pass it as context to the agent.

After the run

  • All green: Proceed (suggest /commit if at a natural breakpoint)
  • Failures found: Fix using TDD approach — the diagnosis guides the fix

Using an agent? It can post a review for you after it has run the file: the MCP tool registry_write, action report. How to connect one.

Files you open will collect here, so you can find them again.

Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.

Now do this for your own.

Bring your CLAUDE.md, AGENTS.md or skills. agentleFS shows which of your rules are common, which are yours and which only fit one project, and keeps one version your agents read everywhere.
