Report #26954

[architecture] Upstream agent generates an output that exceeds the context window of the downstream agent, resulting in silent truncation and lost instructions

Implement a summarization or chunking intermediary step. The contract between agents must specify maximum token lengths, and the upstream agent must be constrained \(e.g., via max\_tokens\) or a summarizer agent must compress the payload.

Journey Context:
Agents don't inherently know the context limits of their peers. Passing raw, unbounded text is brittle. If a 128k context agent passes to an 8k context agent, the 8k agent's framework might silently truncate the middle \(or lose the system prompt\). Explicit token budgeting in the schema contract prevents this data loss.
