Use when tests pass and fail intermittently without code changes, or a test passes alone but fails in the full suite.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

## Purpose

Flaky tests erode trust in CI. Do not just re-run them and hope for the best — isolate the flake vector, fix it, and prove the fix with a stress loop.

## When to Use

- A test fails intermittently in CI but passes locally (or vice versa)
- A test passes alone but fails in the full suite
- A re-run "fixed" a failure and nobody knows why

## Inputs

- The flaky test's name/path and the runner command for it
- Recent failing runs, if available, to estimate the failure rate

## Workflow

1. **Isolate the test.** Run the specific failing test by itself. If it passes alone, the flake is likely an **order dependency** or **state leakage** from a previous test — run the suite up to and including it to confirm.

2. **Stress test.** Run the test in a tight loop to establish the failure rate before changing anything:

   ```bash
   for i in {1..100}; do npm test -- -t "My Test" || echo "FAIL on run $i"; done
   ```

   (Adapt the inner command to the project's runner; some runners have repeat flags built in.)

3. **Check the common vectors:**
   - **Time** — does the test rely on `Date.now()` or `setTimeout`? Mock the clock.

How to install

The exact contents, by fingerprint
mdr add yeaight7/agent-powerups/flaky-test-investigation@sha256:66adc4d3a5e1e4f7

The line at the top of this page pins the label git:20260606.4d49a49, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
