Death to AI slop: a free Claude skill scrubs the vibecoded look off your site

Purple gradients, glowing buttons, emoji in place of icons, shouty headlines and cookie-cutter blocks. A site built by an AI is easy to spot at a glance these days. Designer Damir Sokolovsky decided to do something about it and put a free Claude skill called unslop on GitHub.

The skill starts with an audit: it lists every sign of AI slop and points to where it lives in the code. Then it proposes a direction taken from the product itself: a character, the one or two places where color does the work, and a signature detail. Only after that does it edit the screen in passes, like a designer doing a redline review: spacing, color, icons, copy, type, layout, details, visuals and motion. If the screen is already good, unslop says so and suggests a few small tweaks instead of a redesign.

It works with Next.js, React, Vue, Svelte, Tailwind and plain HTML and CSS, on dashboards, apps and landing pages, and you can even hand it a link to a live site. For a hero image it can generate one through fal, Replicate, OpenAI or Higgsfield, but it shows the prompt and asks before every paid generation. It can also render a square clip under 10 seconds of your screen unslopping itself, ready to post (that part needs Playwright and ffmpeg).

Setup takes a couple of commands: clone the repo, copy skills/unslop into ~/.claude/skills, then type /unslop in Claude Code with what you want fixed. The license is CC BY 4.0, so you can use and modify it commercially as long as you credit the author. The repo went up on Thursday, October 29, and passed 3,000 stars in two days.

Verdict: AI already learned to build sites fast. Now someone is teaching it to make them not look the same.
