Is this a developer tool?
Uiprobe starts from your Figma design. The output speaks your language, not code.
Every finding references what your Figma frame specifies: the font that should be 16px, the spacing that should be 24px, the color that should be your brand blue. No CSS selectors, no DOM inspection.
Developers run it to check their own work. You run it to verify theirs. Same tool, different perspective.
