Composer
Model picker, tools menu, slash commands, and sending messages.
The composer sits under the conversation.

/tools
Grants and credentials are per signed-in user × active workspace. See Connections overview.
Slash / mention commands
Use / or @ in the composer for shortcuts such as:
Send and stop
- Enter sends (⇧Enter for newline — follow on-screen hints)
- Stop cancels an in-flight turn (cooperative cancel, then hard stop if needed)
