The request "diff-analyze" is a task, not a named product, so the best matches are tools whose sources show they analyze code diffs: GitHub's terraform set-diff analyzer and change-analysis skills, Amplitude's diff-intake for analytics briefs, DiffPulse and DiffCI for change risk and test selection, and Kodus for PR diff retrieval.
