Model and effort
The message box has separate model and effort controls. Choose a provider and model for the next message; choose the effort level beside it. The options you see depend on the connected provider and your workspace access. A model change in one session is saved with that session.
Permission mode
The shield control shows the session's permission mode. Ask first requests approval for actions that need it. Full access allows a wider range of actions without asking each time. Read the mode's note before changing it, especially for a session that can edit files or use tools.
Usage and limits
Open Usage to see the limits available for connected accounts. The context ring in a session can show its current seat and live limits when the provider reports them. If a limit is unavailable, check Usage again later or choose another available model or seat.
Review work
Read the agent's result, inspect changed files, and use the review controls before accepting a code change. Keep approvals attached to the specific session and action you intend to authorize.
