Report #45761
[architecture] Context window pollution from upstream agents degrades downstream reasoning quality
Implement progressive summarization with structured handoff schemas: upstream agents output condensed structured summaries \(not raw logs\) into specific schema fields, enforced by JSON Schema validation
Journey Context:
Naive chaining passes full conversation history or raw intermediate outputs, causing context window exhaustion and distracting downstream agents with irrelevant details. The 'telephone game' effect worsens because noise accumulates. The fix is treating inter-agent communication like API contracts with strict schemas—think OpenAPI specs between services. Upstream agents must synthesize findings into specific fields \(e.g., 'verified\_facts', 'uncertainties', 'recommended\_action'\) rather than dumping raw text. This forces information distillation and prevents context pollution. Validation ensures compliance—if the output doesn't match the schema, it's rejected before reaching the next agent. Alternative: full context passing \(fails at scale\) or simple truncation \(loses critical nuance\).
