Should I Combine My Three Research Agents into One?

Hey Marvin A. - why do you build 3 steps/agents in one agent?

1.
I have an agent that researches local speaking opportunities...
2.
A second take specific events and email and create an outreach sequence?
3.
I have a 3rd that does research on an event if I don't have the email included on the event page.

-- Would you end up having all in one agent - or... keep separate? Or would it depend on 3 unique triggers or... ? TIA
