Summary

Melvin Vivas describes a routing pattern in his Coworker app. A generalist agent called Jev, from TypeSafe AI, works out what the user wants, classifies the task and hands it to the bot best suited to handle it. This is a short example of a router or orchestrator in a multi-agent system.

Key points

• The user asks one generalist entry point instead of choosing a specialist bot.
• Jev works out the user's intent and classifies the task.
• The classified task goes to the specialist bot best able to handle it.
• This is the common router/orchestrator pattern in multi-agent systems.
