Git diff plan.md → Implement changes

Looking for a workflow:

  1. plan.md with a set of requirements
  2. Cursor implements
  3. I make changes to plan.md
  4. Ask for a git diff of plan.md
  5. Implement change requirements

What I want is something like this:

@diff plan.md: Implement changes.

or what works today, but is a bit cumbersome to use:

@commit (only plan.md): Implement changes

Ideally, I would like to trigger this when I save the plan.md, or press a button. Ideas?

The new todo feature goes in that direction.
