What problem does it solve? Playwright tests that fail intermittently or only in CI are hard to debug without a systematic approach. This Skill provides a structured workflow to reproduce the failure, categorize its root cause, apply a targeted fix, and verify stability. ## Core Features & Use Cases - Systematic Reproduction: Runs tests with repeat-each, parallel workers, and tracing to reliably reproduce flaky failures. - Failure Taxonomy: Classifies every failure into Timing/Async, Test Isolation, Environment, or Infrastructure categories with matching fixes. - Verified Fixes: Requires 10 consecutive passing runs before considering a fix complete, plus prevention recommendations like retries and trace-on-first-retry. - Use Case: A checkout test passes locally but fails in CI. The Skill reproduces it with tracing, identifies an environment mismatch in viewport size, applies the fix, and confirms 10/10 stable runs. ## Quick Start Ask the AI to fix the flaky test in e2e/checkout.spec.ts that fails intermittently in CI.
