Report #26854

[frontier] Single agent with many tools suffers from tool confusion and high latency

Deploy 'Supervisor' multi-agent topology: lightweight router node uses structured output \(OpenAI tool\_choice or Zod schema\) to emit 'delegate\_to:expert\_name' with specific payload; workers only see their subset of tools, no natural language handoffs.

Journey Context:
Monolithic agents suffer from 'attention dilution' where the model confuses similar tools. The Router pattern \(LangGraph's 'supervisor'\) uses a dedicated routing LLM with constrained outputs \(discriminator field\) to dispatch to specialized agents. Reduces latency \(parallel where possible\) and increases accuracy. This beats 'conversation handoff' patterns which rely on LLM to decide to transfer via chat, which is flaky.
