A read-only drift detector that compares your SPEC.md against actual code without touching anything. Run it when you want to know if your implementation still matches your spec's invariants, interfaces, or task completion claims. It reads the relevant files, classifies violations by severity (HOLD, VIOLATE, MISSING, STALE), and spits out a grouped report with file and line citations. The output is deliberately bare bones, caveman style, and it never fixes anything or edits the spec. It just tells you what drifted and suggests which other skills you might invoke to remedy it. Useful if you treat SPEC.md as source of truth and want periodic audits without side effects.
