I'm building an automated UI Auditor for frontend devs. What features would you actually want in this?

Hey everyone, I'm a solo dev working on a tool that uses a vision API to scan app onboarding screenshots and flag cognitive friction/drop-off points.

Before I finish MVP features, I want to ask the front-end and UX devs here: What would make a tool like this actually useful to your workflow?

Should it output a Markdown report? Do you want it to highlight the exact CSS components causing the friction? Is this idea even worth expanding upon, or should I do some major reworks first? Let me know what you'd actually want to see!
