Test Coverage Gap Finder

Reviews a PR the way a strict test reviewer would when the code looks fine but the test coverage feels shaky. It calls out missing negative and boundary tests, gaps in integration coverage, flaky test risks, and spots where implementation changed but the matching tests didn't. Returns the critical missing tests first, then useful additional ones, described as sample test cases in plain English.

Missing Unit Test Generator

Reads a pasted diff and writes the unit tests it's missing, in your stated test framework, as runnable code rather than a bulleted test plan. - Covers the happy path, the top 3 edge cases, and at least one failure scenario - Uses realistic sample data instead of placeholder strings like "foo" - Tip: ask it to also write a test that would have caught the bug, if the diff is a fix
