What problem does it solve? It provides a rigorous, evidence-based review of a branch's complete change set—including committed, staged, unstaged, and untracked work—so defects, documentation drift, and missing test coverage are caught before a commit, pull request, merge, or handoff. ## Core Features & Use Cases - Full-range change review: Pins a fixed merge-base and reviews the union of committed diffs plus all uncommitted and untracked files, building an impact closure of callers, build wiring, and related specs. - Three independent review axes: Evaluates code correctness against five repository C++ skills, verifies documentation-to-implementation alignment, and maps every affected behavior to positive, negative, boundary, and regression tests. - Verified check execution: Runs the checked-in CMake/CTest presets, sanitizer builds, and the project standards checker, recording each command as Passed, Failed, Blocked, Not available, or Not applicable. - Use Case: Before opening a pull request on a C++ feature branch, run this Skill to receive a severity-ordered findings list (P0–P3), a behavior-to-test coverage matrix, and a final Pass, Needs changes, or Blocked verdict. ## Quick Start Use $review to review this branch and all uncommitted changes before I open a pull request.
