# Diff Visual

> Catch up on a git change before you review it — background on the system it lands in, the idea behind it, a literate diff of the real extracted code, and a five-question quiz. Use whenever the user wants to understand, explain, walk through, or get up to speed on a diff, branch, commit, or PR — including agent-written code they didn't write themselves, or a teammate's PR they're about to review. Also use for "visualize this diff" and "what changed here". Accepts branch names, commit hashes, HEAD, PR numbers, or commit ranges.
