Overview
The router is the central decision point in a multi-agent architecture. It analyzes the request and assigns each subtask to the system best suited to perform it.
A full-stack software project may require:
- User-interface design.
- Front-end implementation.
- Back-end logic.
- API construction.
- Testing.
- Integration.
- Final validation.
Instead of asking one agent to perform all of this in one context, the router can divide the task. In one example stack, Claude acts as the manager, Gemini handles front-end work, and Codex handles back-end and testing work. Claude then collects the pieces and fixes integration issues.
The same routing logic can be extended beyond software:
- A video-understanding task can be routed to Gemini because of its multimodal abilities.
- A difficult reasoning task can be routed to Claude.
- A back-end programming or test-driven task can be routed to Codex.
- A real-time information task can be routed to a system designed to retrieve current web data.
The important idea is not a permanent ranking of products. It is the act of analyzing a task by capability and sending each part to an appropriate worker.
