Hi HN — I built semantic-diff for myself, and it turned out surprisingly useful. Regular git diff shows what changed. semantic-diff tries to answer: – why was this change made? – what could break? – what should the reviewer focus on? It gives you a ranking from critical to low, with review questions prioritized. The funny part: I ran it on its own commits during development. The tool roasted me harder than any reviewer I've had ))) Runs locally, hooks into pre-push, also works as a GitHub Action. Would love feedback, especially from people doing code review at scale.
