A2UI explained for frontend engineers
How Google's declarative agent UI spec lets LLMs propose native component trees across trust boundaries — without executing generated code.

Series · Part 2
Output contracts: structured outputs and tool calling
How JSON Schema, tool use, and typed objects form the first protocol layer between LLM responses and frontend interfaces.
