Problem Statement

I find it very frustrating to have the CLI current screen output flushed at auto-compaction time, while I'm reading it...

Proposed Solution

There should be some option to give the user a chance to control it, like "auto-compaction time reached - press Enter to continue" (or even an option to provide a prompt as with the /compact command).

Alternative Solutions

Apart from manually grepping into history jsonl files, I'm not aware of an alternative, but maybe I am missing something.

Priority

High - Significant impact on productivity

Use Case Example

I'm reading claude's output during a complex task, auto-completion % decreases and reaches 0%, then the whole screen is suddenly reset, this is very frustrating.
