I built GhostMark because text is a terrible pointing device. I kept describing “the button in the top-right” when one arrow would be clearer. GhostMark turns that into a small visual loop for Claude Code: paste a screenshot, draw the arrow or user flow you mean, then press Enter. It is free, MIT-licensed, runs locally on macOS, and does not upload images or collect analytics. The installer is signed and notarized by Apple. I would especially love feedback on how you use it for UI changes and user-flow sketches. GitHub: https://github.com/alan890104/Gh...

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
