Report #46554

[architecture] Passing the entire raw conversation history between agents, exhausting context windows and degrading the receiving agent's focus

Summarize the departing agent's context into a structured, dense payload before handing off, rather than passing the full transcript.

Journey Context:
A research agent might use 100k tokens to find an answer, but the coding agent only needs the extracted API signature and requirements. Passing raw history causes the receiving agent to get distracted by irrelevant reasoning traces. Summarization trades minor information loss for massive gains in context utilization and focus.
