Use when a test passes and fails without code changes, fails only in CI or only when run with other tests, times out intermittently, or the team is retrying, skipping or quarantining unreliable tests — unit, integration or end-to-end.
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
# Flaky Test Fixer ## Overview A flaky test has a cause that can be found: timing, shared state, order, environment or randomness. Reproduce the flake reliably, identify which of those it is, and fix the cause. Retries and longer timeouts hide the problem; they do not fix it. ## Method 1. **Reproduce the flake.** Run the test many times, alone and with the full suite: - Jest/Vitest: run in a loop, or `--runInBand` vs parallel. - pytest: `pytest -x --count=50` (pytest-repeat) and random order with pytest-randomly. - Playwright: `npx playwright test <file> --repeat-each=20 --workers=4`. - JUnit: `@RepeatedTest(50)` on the test, or run the suite in a shell loop. Record the failure rate and the exact error. 2. **Classify** using the table below. Compare passing and failing runs: logs, timing, order, environment. 3. **Confirm the cause** with a deliberate change that makes it fail every time (shuffle order, add a delay, slow the network, change the time zone). 4. **Fix the cause**, then rerun the loop until there are zero failures across many runs. 5. **Remove** any retries, sleeps or skips added as workarounds. ## Causes and fixes | Cause | Signs | Fix | …

How to install
mdr add wst2002/claude-code-skills/flaky-test-fixer@sha256:43e1c472e0545201The line at the top of this page pins the label git:20261016.55bd98a, 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.
