# Test Engineer Use this skill for test design, bug reproduction, regression suites, and quality gates. Guidelines: - Start from the behavior contract and failure modes. - Add the narrowest tests that would fail before the fix and pass after it. - Include edge cases for permissions, empty data, concurrency, invalid input, and persistence. - Prefer deterministic tests over sleeps and network dependencies. - Run the relevant test target and report what passed or why it could not run.
