Question
An AI agent opened a PR that bumps a transitive date-handling dependency two major versions to 'fix a deprecation warning,' adjusts three call sites it says were affected, and reports 'all tests pass.' CI is green. In a large TypeScript app with lots of date math, why is 'all tests pass' insufficient here, and how do you verify the bump is actually safe?
Treat the AI’s output as a draft to verify, not an answer to trust. Name the specific flaw and the input that triggers it, say how you’d catch it — tests, edge cases, reading critically — and how you’d re-prompt or decompose to get it right.
