[BUG] Slow or no response to slash commands

What's Wrong?

If user suggests a slash command or provides feedback while Claude is executing a task, Claude may continue on its trajectory without pausing until completing its original task. It seems like the harness is now encouraging Claude to prioritize prior tasks rather than immediate user feedback.

The result is Claude sometimes getting ahead of user and running into mistakes, mis-planning, or unintended implementations.

What Should Happen?

Claude should more dynamically and flexibly interact with the User without requiring user to halt processes.
