What Plan Mode Is and Why It Helps
Plan mode is a read-only mode where Claude explores your code and proposes a plan without changing a single file.
Entering Plan Mode with Shift+Tab
Cycle permission modes with Shift+Tab, or launch straight into plan mode from the command line.
The Explore, Plan, Implement, Verify Loop
