Claude Code issue proposes a live input hook to edit prompts while typing

A GitHub issue proposes a new UserInputChange hook for Claude Code.

The request says Claude Code already hooks most surfaces except the prompt input buffer. It argues that UserPromptSubmit only fires after Enter, which is too late for modifying or assisting the live prompt. The proposed solution is a debounced event that fires while the user is typing, with JSON input/output so hooks can suggest corrections or annotations before submission.
