Test Flakiness Detection

A flaky test is one that sometimes passes and sometimes fails without any code change. Flaky tests are worse than no tests in some ways — they train the team to ignore red CI runs, masking genuine failures. This skill identifies them, explains likely causes, and recommends whether to quarantine or fix each one.

When to run:

• Polish phase (tests have had many runs; statistical signal is reliable)
• When developers start dismissing CI failures as "probably flaky"
• After /regression-suite identifies quarantined tests that need diagnosis
