Mixture of Experts Routing
Route each request to one or more domain-expert agents, where each expert holds deep capability in a narrow area.
Intent & Description
🎯 Intent
Route each request to one or more domain-expert agents, where each expert holds deep capability in a narrow area.
📋 Context
A team is building one agent that serves users across several substantially different professional domains — for example legal questions, medical questions, financial planning, and technical support. Each of these domains has its own vocabulary, its own authoritative sources, and its own conventions for what a good answer looks like. A single shared prompt cannot credibly carry deep expertise in all of them at once because the prompt budget and the model’s attention are finite.
💡 Solution
Define experts (specialised system prompts, tool palettes, possibly fine-tuned models). A router classifies queries by domain. Route to one expert (top-1) or to multiple experts whose outputs are aggregated. Distinct from standard routing by emphasising deep specialisation per expert.
Real-world Use Case
- Users in specialist domains feel under-served by a generalist agent.
- Domain experts can be defined with their own prompts, tools, or fine-tuned models.
- A router can classify queries by domain reliably enough to dispatch.

Advantages
- Depth per domain.
- Independent expert evolution.
Disadvantages
- Domain count grows expert maintenance linearly.
- Cross-domain queries fall through cracks.
