[frontier] Monolithic agent prompts cause the agent to ignore tools or hallucinate conflicting instructions

Adopt Prompt Routing or Mixture of Experts Agents. Use a lightweight classifier LLM to route the user intent to a specialized, minimal agent with a narrow prompt and specific toolset.

Journey Context:
As capabilities grow, monolithic prompts exceed the LLM's attention capacity, leading to tool ignorance and instruction conflicts. A router/specializer topology keeps context windows small and focused. The tradeoff is the latency and cost of the routing step, but it drastically improves accuracy on complex, multi-domain tasks.
