Module: AgUi::Messages

Defined in:
lib/ag_ui/messages.rb

Overview

Translates AG-UI wire messages (RunAgentInput.messages — raw camelCase hashes) into brute's canonical Brute::Message log, ready for the turn pipeline. This is where client-executed tool results re-enter the conversation: the assistant's toolCalls and the matching tool messages must round-trip faithfully or the model repeats calls (doc 03 gotchas).
