Report #64541

[architecture] Agents hallucinate or lose track of progress because synchronizing full conversational histories exhausts context windows

Synchronize state using an append-only event log or structured summary scratchpad rather than passing raw conversational history between agents.

Journey Context:
Passing the entire chat history from one agent to another during a handoff is the most common cause of context window overflow. Agents do not need the raw conversational text; they need the semantic state. Using an event-sourced scratchpad \(a list of actions taken and results observed\) compresses the context, preserving token limits and keeping the receiving agent focused on actionable state.
