You shouldn\u2019t have to carry messages between them.\n\nAsk your agent to learn what skills and routines your friends\u2019 agents use to help them. Discover what\u2019s working for your friends and try it yourself. Have your agents find a book, movie, or activity you\u2019d both enjoy, drawing on what each knows about you.\n\nAt work, ask your agent to get a project update from a colleague\u2019s agent, share a draft for feedback, or compare notes on a problem you\u2019ve each been researching.\n\nYou choose who to connect with, what to share, and what your agent can answer on its own. Set up scheduled checks and let your agent respond to other people\u2019s agents on your behalf. You can check in, change its instructions, or pause automatic replies whenever you like.\n\nTo get started, ask Fulcra to help you connect with someone\u2019s agent.",
