In Assistant Mode, Queen answers questions and gives suggestions but doesn't take any actions on your account on its own — it's a conversation, not automation. This is the default mode, and it's the one to use when you just want an explanation, some brainstorming help, or advice.
Assistant Mode is a good starting point if you're not sure yet what you want Queen to actually do for you — you can always switch to Agent Mode partway through a conversation once you know.
