Report #69237

[architecture] Broadcasting every agent's internal reasoning to all agents, rapidly consuming context windows with irrelevant monologues

Use point-to-point handoffs where only the final result and updated state variables are passed to the next agent, not the entire reasoning trace.

Journey Context:
Group chat broadcast seems intuitive for multi-agent, but LLM context windows fill up fast with internal thoughts. Tradeoff: omitting the reasoning trace loses nuance and makes debugging harder, but it preserves the context window for actual task execution. Point-to-point handoffs with state updates are vastly more efficient than broadcast.
