# Smt Verify

> Convert VDM-SL proof obligations (POs) to SMT-LIB and verify them with the Z3 solver. Triggered by "prove POs", "verify with SMT", "check with Z3", "auto-verify proof obligations", "prove the spec is correct", or "find counterexamples". Also responds to Japanese: 「POを証明して」「SMTで検証して」「Z3で確認して」等。 Used as the next step after PO generation with verify-spec, or for end-to-end PO generation + SMT verification.
