Stop Claude Code asking for permission (without losing control)

Claude Code prompt suggestions cost usage: how to turn them off
Prompt suggestions in Claude Code, the gray text after each reply, come from an extra request to your model that counts toward your plan. How they work, when they skip, and how to turn them off in the terminal, Desktop and the cloud.
