Agentic UI Contract

Use this when building or refactoring toward agentic product behavior.

Core Contract

1. Model decides WHAT to do.
2. Tools decide HOW it is done.
3. UI schema decides HOW it is rendered.

This gives open-ended behavior without fragile freeform execution.

Architecture Shape

• Planner layer (LLM): intent interpretation + tool selection + sequencing.
• Tool layer (deterministic): typed side effects and data reads.
• UI contract layer (typed blocks): constrained rendering catalog.
• Control layer: auth, guardrails, tracing, evals, fallback.
