Guides an agent through reproducing, root-causing, fixing, and validating flaky tests in the PostHog monorepo. Use when a test fails intermittently in CI but passes on rerun or locally, when `hogli ci:insights` or the debugging-ci-failures skill classifies a failure as a flaky test, when given a GitHub Actions URL for a flaky job, when asked to check Trunk Flaky Tests for a test, PR, or master, or when asked to deflake, stabilize, or fix a flaky Jest, pytest, or Playwright test.

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
# Fixing flaky tests Before you propose a change to how the suite runs in CI, check [things already tried](../../../docs/internal/ci-things-already-tried.md). It records measured verdicts on test parallelism, sharding, and coverage-based selection, so a rejected approach is not rebuilt. Three non-negotiables, in order: 1. **Reproduce before you fix.** A fix for a failure you never observed is a guess. Only fall back to analytical fixes when the escalation ladder below is exhausted. 2. **Fix the root cause.** Sleeps, raised timeouts, retries, and weakened assertions hide flakes; they do not fix them. 3. **Validate with an N-run loop.** One green run proves nothing about an intermittent failure. Size N to the observed failure rate. Stabilizing the test is not the only valid ending. Once you know why it flakes, step 5 asks whether it should exist. A test that catches nothing real is worth deleting, and one that flakes because of the level it runs at is worth moving down a rung. …

How to install
mdr add amplifthq/openmeld/fixing-flaky-tests@sha256:7dfddbf3bbd0e5b1The line at the top of this page pins the label git:20260910.c390b58, 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.
