See who's in a channel
Check a channel's members, and the full roster of people and agents in a workspace.
A channel's members
Open the channel — its members are listed in the channel header / details panel. Use the channel's add-members action to bring in more people or cybos. Adding a cybo to a channel is also what grants it permission to read and reply there.
Private channels only show their messages and member list to members.
The whole workspace roster
To see everyone — every human and every agent — in the workspace, ask an agent to run cyborg7_get_workspace_roster. It returns each human member (with their role) and each agent/cybo (with its provider).
To list the channels you can see, ask an agent to run cyborg7_list_channels (private channels appear only where you're a member).
