Sessions
Start a thread, choose a model, and work with collaborators.
Use New session to open a draft. Choose an available project and its execution environment, select a model, and enter your request. Opening a draft does not start a model request until you send it.
In a shared project, the conversation belongs to that project on its host. Other approved collaborators can view or participate according to their permissions. The participant who sends a request supplies their own provider connection; switching the sender does not authorize use of someone else's AI credentials.
Follow-ups
Follow-ups can steer the running agent at a safe boundary or wait in its queue. The default behavior is configurable in Preferences. The composer shows the applicable action for the current run.
Use the session's tools to review changes, inspect files, and open project previews. Terminals and other actions depend on the selected environment and, for guests, their collaborator permissions.
Tabs and unavailable hosts
Closing a tab leaves the underlying session intact. When a shared host becomes unavailable, that tab shows an offline notice instead of loading its files and history. You can navigate elsewhere or start a local session. Offline projects are disabled in the new-session project selector.
If you lose project access, the tab explains that access was removed. Ask the host for a new invitation if you need to rejoin.
