How do you point out UI changes to coding agents?

Before GhostMark, I kept writing things like “move the button near the top-right below the banner” and hoping the agent understood the same element I meant.

For a one-arrow change, text feels like the wrong interface. It gets worse when the feedback is really a user flow rather than a single location.

I’m curious how other people handle this today:

- describe the position in text

- annotate the screenshot first

- provide coordinates

- use a design spec or Figma

- something else

Which visual feedback workflows are actually working well for you with Claude Code or other coding agents?
