Interface Review skill: what it does and how to install it

What it does. Reviews a selected Git change: resolves its scope and exclusions, reads both sides of the diff, expands changed files to affected UI surfaces, and classifies findings as introduced, regressions or pre-existing. It passes the scope and findings to better-interface for coverage, severity and verdict without modifying the working tree.

When to use it. Use for branch, pull request or uncommitted interface reviews. It does not cover general correctness, tests, security or performance, and asks rather than inventing a review when no change is present.
