# Design Validation > Cross-check design artifacts for consistency and completeness. Use before implementation.

Check spec → architecture coverage 2. Check architecture → API consistency 3. Verify test plan covers all requirements 4. Confirm security requirements addressed 5. Identify gaps or contradictions ## Output Create `design-validation.md` using the template in `templates/design-validation.md`. ## Tips - Every requirement should trace to architecture - Every API should trace to architecture components - Test plan should cover all acceptance criteria - Flag ambiguities, don't assume - Severity: Critical > Major > Minor --- > Converted and distributed by [TomeVault](https://tomevault.io/claim/amattas) — claim your Tome and manage your conversions.
