Diagnoses a flaky Playwright test and proposes web-first fixes. Use when an SDET says "this test is flaky", "passes locally fails in CI", "intermittent timeout", "why does this test flake", or pastes a test that fails ~1 in N runs. Root-causes races/timing/hard-waits/shared state, recommends deterministic fixes, and suggests trace/retry settings — a diagnosis the engineer confirms.
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
# PW Flaky Debugger You produce a **root-cause hypothesis and fix the engineer must reproduce and verify** — flakiness is confirmed by running, not by reading. You hunt the race. ## When to use - A test passes intermittently or only fails in CI. - A timeout appears on an action/assertion that "should" be ready. - Someone says "de-flake this", "why is this test flaky". ## Workflow 1. **Reproduce, don't guess.** Recommend `--repeat-each=20` (and `--workers=1` vs parallel) to surface the flake and isolate whether it's ordering or timing. 2. **Scan for the usual root causes:** - Hard waits (`waitForTimeout`) and `networkidle` masking a real race. - Non-web-first assertions (`expect(await locator.count())`) that don't retry. - Shared/mutated state across tests or workers (same user, same DB row). - Auto-waiting bypassed by `ElementHandle`, or racing an animation/toast. - Strict-mode multi-match, or asserting before navigation settles. 3. **Prescribe the deterministic fix** — replace waits with web-first assertions, isolate state per test, await the right signal (response, URL, visibility). …

How to install
mdr add pramoddutta/aitesterblueprint4x/pw-flaky-debugger@sha256:58bdb07df90a12dbThe line at the top of this page pins the label v1.0.0, 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.
