 > 💡 **Not sure which model to pick?** Select **`Auto`** from the model picker to let Copilot automatically choose the best available model for each session. This is a great default if you're just getting started and don't want to think about model selection.

 > 💡 **Switching agents**: You can switch to a different agent at any time by using `/agent` or `--agent` again. To return to the standard Copilot CLI experience, use `/agent` and select **no agent**.
 
+> 💡 **Agent mode is session-scoped**: The agent you select applies only to the current session. When you start a new session with `/new`, `/clear`, or by opening a fresh terminal, Copilot returns to its default mode — your agent selection does not carry over automatically. This means each session starts with a clean slate, which is a good habit to keep your work focused.
