# Medassist Architecture Guard > Guard MedAssist architectural boundaries and route/data-flow conventions when changing backend or frontend code, including equivalent requests phrased in German.

Frontend network calls use `/api/*` paths. 2. Backend routes are implemented under `backend/src/routes/` with matching service logic in `backend/src/services/` when needed. 3. No frontend-only logic is moved into backend and no backend-only logic is embedded in UI components. 4. Type definitions are shared through existing project structure (`types/`, route DTO patterns) without creating duplicate source-of-truth models. ## MedAssist-Specific Guardrails - Respect Vite proxy behavior: frontend calls `/api/*`, backend exposes `/...` routes. - Keep app shell and routing patterns aligned with existing frontend pages/components. - Prefer minimal, local changes over broad restructures. ## Response Format When this skill is used, summarize: - Which architectural checks were applied - Which files are affected - Any boundary risks found and how they were resolved --- > Converted and distributed by [TomeVault](https://tomevault.io/claim/danielvolz) — claim your Tome and manage your conversions.
