What's Wrong?

On narrow terminal "Context left until auto completion..." writing renders as one letter column making it super high and taking up tons of vertical space as on picture below:

What Should Happen?

Claude Code CLI should be smarter about layout on more narrow terminals always (also in /menus etc), Claude Code CLI acceptence tests should probably include tests covering all terminal widths and fuzzing on configuration (like lengths of custom commands, plugin names etc) and asserts for esthetics utlization of terminal space and definitely not such such wated spaces of missing important information.
