Who it's for: people who connected Coworker and other connectors (Stripe, Intercom, etc.) to Claude.
Do I get separate answers? No. Claude gives one answer and calls whichever connected tools it needs, often several in one turn. Claude lists the tools it used above the answer. If you want each part labeled by source, ask for that in your question.
Which connectors can it use? Only the ones turned on for that chat, and only what your own account can see in each system.
Can I control the source? Yes, say so in the question, for example "check Stripe for billing and Coworker for everything else."
