Systematically reproduces and debugs flaky CI test failures using a mandatory execution-first workflow.
This skill provides a rigorous, execution-first workflow for resolving intermittent test failures that occur in CI environments but are difficult to replicate locally. By enforcing a mandatory reproduction sequence—including automated port management, environment synchronization, and production-build testing—it eliminates guesswork and ensures that developers identify the root cause of timing issues, bundling errors, or race conditions before attempting a fix. It is specifically optimized for Payload CMS environments using Playwright and Vitest.
