264264To set a baseline for the whole session instead of listing individual tools, pass a [permission mode](/docs/en/permission-modes). For `-p`, the [built-in starting permission mode](/docs/en/permission-modes#which-mode-a-session-starts-in) is Manual on every plan, so pass the permission mode you want:
265265
266266* **`auto`**: pass `--permission-mode auto` to have a classifier review most actions instead of you
267* **`dontAsk`**: Claude Code denies anything not in your `permissions.allow` rules or the [read-only command set](/docs/en/permissions#read-only-commands), which is useful for locked-down CI runs. `AskUserQuestion`, connector tools [your organization set to `ask`](/docs/en/mcp#organization-controls-on-connector-tools), and MCP tools marked [`requiresUserInteraction`](/docs/en/mcp#require-approval-for-a-specific-tool) are denied even when an allow rule matches
267* **`dontAsk`**: Claude Code denies every call that would otherwise prompt, which is useful for locked-down CI runs. Actions that need no approval in Manual mode still run, such as file reads in your working directories and the [read-only command set](/docs/en/permissions#read-only-commands), and so do actions your `--allowedTools` entries or `permissions.allow` rules cover. `AskUserQuestion`, connector tools [your organization set to `ask`](/docs/en/mcp#organization-controls-on-connector-tools), and MCP tools marked [`requiresUserInteraction`](/docs/en/mcp#require-approval-for-a-specific-tool) are denied even when an allow rule matches
268268* **`acceptEdits`**: Claude writes files without prompting, and Claude Code auto-approves common filesystem commands such as `mkdir`, `touch`, `mv`, and `cp`. The [actions no mode auto-approves](/docs/en/permission-modes#actions-no-mode-auto-approves) still apply. Apart from the read-only command set, other shell commands and network requests still need an `--allowedTools` entry or a `permissions.allow` rule. See [what `acceptEdits` auto-approves](/docs/en/permission-modes#auto-approve-file-edits-with-acceptedits-mode) for the full list
