What AI agents do you have running in production?

There are so many new AI agent platforms ( @Wordware @Lindy @CrewAI @zapier and so on) that I'm finding myself curious how everyone is using them.

What AI agents are you using in production? What do they do? Are they working and reliable? What would make them better? Are they replacing roles? Augmenting existing ones?

And if you're not yet using agents in production, why not? What should these companies build that would make you adopt it quicker?
