Review Delta

This is a code review workflow that only looks at what changed since your last commit, plus everything those changes might break. It uses a code graph to trace dependencies and find the blast radius automatically, so you're not burning tokens on unrelated files. You get changed functions, their callers, inheritance chains, and test coverage gaps all in one context window. Useful when you want a review of your branch but don't want to feed your entire codebase into the model. The token savings are real, it just depends on having git history and building that graph first.
