Stop describing pixels to your AI agent — annotate them instead
If you pair-program with an AI agent — Claude Code, Codex, Cursor, whatever — you've lived this moment. You take a screenshot of your UI, paste it into the chat, and then you start typing:
"See the button in the top-right? No, not that one, the other one, next to the misaligned icon — make it full width on mobile and fix the icon while you're at it."
You're describing pixels in prose. And the agent, bless it, does its best to guess which of the six buttons in the screenshot you actually meant.
It gets worse. A lot of chat UIs only keep the image from your clipboard and silently throw away any text you copied alongside it. So even the careful caption you wrote never makes it through. Half your context evaporates between Cmd+C and Cmd+V.
