Problem Statement

I have a very different iterative planning workflow that I use, so I am never going to actually select "plan mode" myself. I always have to cancel it when Claude decides "it's time to plan!".

Proposed Solution

It would be great to have an official setting to either: deny the planning tool completely (no option in tab switcher either), or a very least deny the automatic tool use to enter planning mode (I am fine if this triggers a hiccup in Claude's output, I can always redirect after).

Alternative Solutions

I am testing out adding EnterPlanMode to my Deny list, but that seems pretty hacky (what if the name of that tool changes, or there is some other way to trigger it?).

Edit: This does appear to work for now, but as mentioned, an official true/false setting for planning mode as a whole or automatic planning at a minimum would be way better.

Priority

Medium - Would be very helpful
