Report #42798

[architecture] Downstream agents fail or hallucinate because accumulated context from prior agents exceeds the LLM context window

Implement a summarization or context-compression step at each agent handoff boundary, passing only the distilled artifacts and essential state rather than the full conversational history.

Journey Context:
In a chain of A -> B -> C -> D, passing the entire history makes the prompt exponentially large. Eventually, it hits the token limit, causing truncation \(losing early instructions\) or API errors. Agents only need the specific inputs required for their task, plus a high-level summary of what happened previously. Summarization at the boundary keeps the context bounded and focused.
