Permission Modes

Permission modes for tool approval, set via permissions.defaultMode in settings.json:

{ "permissions": { "defaultMode": "acceptEdits" } }

default — standard behavior: prompts for permission on first use of each tool.
acceptEdits — automatically accepts file edit permissions for the session.
plan — Plan Mode: Claude can analyze but not modify files or execute commands.
dontAsk — auto-denies tools unless pre-approved via /permissions or permissions.allow rules.
bypassPermissions — skips all permission prompts (requires a safe environment).

You can tell Claude to launch with a specific permission mode: claude --permission-mode plan.

In the interactive shell you can toggle modes using Shift-Tab: default → plan → acceptEdits (cycles).
