Test Stress Tester

This skill provides a programmatic way to run tests repeatedly to catch flakiness, race conditions, or intermittent failures that only surface in CI.

When to use

• When a test passes locally but fails in CI.
• When you suspect a race condition in asynchronous code.
• When you want to verify the stability of a new feature before merging.

Scripts

Runs a vitest test file a specified number of times and reports the failure rate.
