[synthesis] Verbose sub-agent returns cause context eviction and orchestrator derailment

Enforce strict output token limits and mandatory summarization on sub-agent returns, ensuring the orchestrator only receives a structured JSON status and a 1-2 sentence summary, never raw stdout.

Journey Context:
Orchestrators often fail silently at the end of long tasks. We blame long context degradation, but the root cause is sub-agents dumping verbose stdout into the parent context. This pushes the main objective out of the attention window. The tradeoff is losing debuggability \(raw logs\) vs. maintaining orchestrator focus. The right call is strict output schemas for inter-agent communication, treating sub-agent stdout as toxic to the parent's working memory.

environment: Multi-Agent Systems · tags: context-eviction verbose-stdout orchestrator-failure · source: swarm · provenance: AutoGen multi-agent conversation patterns combined with LLM context window attention mechanisms and Unix piping philosophy \(structured data over pipes\).
