Anti-slop prompt builder
Pick the design habits you want your AI coding tool to avoid, and get a block to paste into your prompt.
Nothing leaves your browser. This page makes no network requests. The first group is the list from my post, Stop your AI website from looking like slop. AI models don't follow it perfectly, so expect to still see the odd one slip through.
Your block
How to use it
Paste the block into the first prompt, just after your own instructions. If you use a coding tool with a project file, such as CLAUDE.md, you can put it there instead so it applies every time.
Leave out any rule you disagree with. Some of these are my taste, not facts. If you'd rather give the AI more to work with than a list of don'ts, try the website brief builder.
