How do I find all contacts that have been tagged with a specific label?
Simply ask the agent to run the get_contacts tool with the target tag. It will return a list of matching contact profiles, including their names and phone numbers.

Yes. The send_message tool supports a media_url parameter, allowing you to include images or other media files in your outgoing messages.
