Notion Custom Agents Can Call Sub-Agents
Notion Custom Agents can now call other Custom Agents as sub-agents.
Each sub-agent keeps its own instructions, context, access permissions, and model. The main agent hands off focused work, then brings the results back to finish.
How to use it:
- Open the main agent's Settings.
- In Tools and access, add the Agents it can call.
- In Instructions, spell out what to hand off and what each sub-agent should return.
- Give the coordinating main agent a stronger model, and give specialized sub-agents faster, lighter models.
- Start with 1–2 sub-agents, test each one on its own, then wire the full flow.
