Mode

Shift+Tab

Mode What runs without asking Best for
default Reads only Getting started, sensitive work
acceptEdits Reads, file edits, and common filesystem commands (mkdir, touch, mv, cp, etc.) Iterating on code you’re reviewing
plan Reads, plus classifier-approved commands when auto mode is available Exploring a codebase before changing it
auto Everything, with background safety checks Long tasks, reducing prompt fatigue
dontAsk Only pre-approved tools Locked-down CI and scripts
bypassPermissions Everything Isolated containers and VMs only
