Multi-agent products are everywhere—but is anyone using them every day?

I’ve been experimenting with multi-agent tools recently, especially workflows where one agent researches, another executes, and a third reviews the result.

The demos are impressive, but my experience has been mixed. For smaller tasks, coordinating the agents sometimes creates more work than using one capable agent. I’ve also run into duplicated research and inconsistent outputs.

I’m curious whether anyone here has found a multi-agent workflow that genuinely stuck:

• What task are you using it for?

• What does the agent team do better than a single agent?

• How do you handle coordination and quality control?

• Which product is still part of your workflow after the initial experimentation?

I’d especially love to hear about real, recurring use cases rather than one-off demos.
