Review code and propose evidence-based representation improvements using Tim Ottinger's Eight Code Virtues, SPOT, ZOM, and the improvement test. Use for broad craft, refactoring-readiness, clean-code, knowledge-representation critique, or discovering data clusters, data classes, and class-splitting boundaries. Do not use for bug/security-only review, implementing behavior test-first, or a focused identifier-naming task; those belong to the relevant specialist workflow.
