176Auto mode is the [built-in starting permission mode](/docs/en/permission-modes#eliminate-prompts-with-auto-mode) for interactive terminal sessions on Pro, Max, and Team plans: a classifier reviews actions instead of you, and Claude edits most files and runs most commands without asking you. On other plans, Manual mode is the built-in starting permission mode. For the session you start right after installing, see [First session after an install or upgrade](/docs/en/env-vars#first-session-after-an-install-or-upgrade).
176With Claude Code v2.1.283 or later, auto mode is the [built-in starting permission mode](/docs/en/permission-modes#eliminate-prompts-with-auto-mode) for interactive terminal sessions: a classifier reviews actions instead of you, and Claude edits most files and runs most commands without asking you. On earlier versions, auto mode is the built-in starting permission mode only on Pro, Max, and Team plans.
