When you tell Cursor or Claude Code to "make it look like that site", it has to guess. The colors come out roughly right, but the spacing, the hover states and what happens at smaller widths usually don't. Stylepack gives the agent something measured instead. You paste a URL. It opens the page in a real browser at four widths and in both themes, then writes out what it finds: a DESIGN.md (colors, type, spacing, components), a BEHAVIOR.md (hover, tooltips, menus, motion, responsive changes), tokens and screenshots. You drop them in your repo and point the agent at them. It works with Claude Code, Cursor, Copilot, v0 and Lovable. Limits: it only sees public pages, so anything behind a login is out. And how closely the agent rebuilds from the pack still depends on the agent. You get 3 packs a day free with no account, or 10 a day with a free account. https://stylepack.ai I'd like feedback on two things. Is BEHAVIOR.md useful to you, or do you only care about the tokens? And if you run it on a site you know well, what did it get wrong?   submitted by   /u/Mammoth-Connection17 [link]   [comments]
