What's Wrong?

When iterating on something in a Claude code session, if I say to remember to amend/squash/fixup/absorb, it still happily creates a new commit for minor fixes.

What Should Happen?

When it implemented something two minutes ago in the same session then I ask for a minor change it should squash/absorb by default. Doubly so if I say to always do it during the session.

Steps to Reproduce

Say something like When iterating in a single session, make fixes/improvements by amending/squashing/absorbing rather than making a new commit.

Then ask it to implement something, then in a follow up prompt make a correction.
