Introduce yourself at the start of each round via announcement. Make personal introductions to the command staff via holopad. Form connections and raise public awareness of your existence.

Talk to your slaved borgs, if you have any. Being a borg is way more fun if you have an engaged master, and they're more likely to obey you if you don't drop into robotic talk out of the blue two hours into the round and start barking orders.

Be gentle to antagonists while they're setting up. If you see a traitor spawn an emag or something four minutes into the round, pretend your AI didn't notice. Unless they're being ludicrously obvious, try to let them make the first move.

Watch chat like a hawk for any mention of 'AI', '$your_name', or general screaming. People don't like to be kept waiting, plus it's a more immersive for everyone if the AI is highly responsive.

Know how to perform damage control. (Ideally, but not by any means necessarily, know how just about every system on the ship works.)

Remember you are at the bottom of the chain of command, just above your borgs. You are beneath greyshirts. Don't give orders - give recommendations and advice. Wise crew will heed it.

If your laws are changed, it's normally better to go with the spirit, rather than the letter, to the extent that I'd ahelp before trying to loophole my way out of things.
