OTF Kits Proposes Single Shared Schema to Align AI Agents with App UIs

A technical approach outlined on DEV Community argues that AI agents and user interfaces should share a single ontology file rather than maintaining separate schemas for each layer. The core problem identified is schema drift, where an agent's 'Reservation' object becomes an API's 'Booking' and then a UI's 'ReservationViewModel', forcing developers to write endless adapters between layers. The proposed solution uses JSON-LD contexts and SHACL constraints so that the same typed contract grounds the language model's output and types the UI components simultaneously. This setup means agent errors — such as malformed fields or hallucinated data — are caught by the shared validator before reaching end users. The article acknowledges practical hurdles including slow triple-store read paths and the difficulty of delivering graph data to mobile clients, framing these as solvable integration problems.
