-        By default, goose names your session using the current timestamp in the format `YYYYMMDD_<COUNT>`. If you'd like to provide a specific name, this is where you'd do so. For example to name your session `react-migration`, you would run:
+        goose sessions are given an auto-generated name based on the context of your initial prompt.
 
-        ```
-        goose session -n react-migration
+        If you'd like to provide a specific session name, you can do so when starting a session. For example, to name your session "react-migration", run:
+
+        ```sh
+        goose session --name react-migration
         ```

+:::tip Disable AI-generated Session Naming
+Use [`GOOSE_DISABLE_SESSION_NAMING`](/docs/guides/environment-variables#session-management) to keep the default name instead of calling a model to generate one (useful in CI/headless workflows). The default name in goose Desktop is "New Chat" and the default name in goose CLI is "CLI Session".
