The Slop Catcher

What you get

Your website looks like AI made it. Your visitors can tell.

The Slop Catcher tells you exactly why.

It reads your page like a picky designer would. Then it hands you a list:

• Purple gradients
• Emoji used as icons
• Three boxes that all look the same
• Made-up lines like "trusted by 50,000 teams"

Each one comes with the exact line to fix.

Then you say "fix it." And it redesigns the page.

Free. No keys. No accounts. About 5 minutes.

One thing to know

It's a set of instructions for Claude, not magic. The redesign is cleaner, not award winning.

And sometimes it makes up text, like a fake number. Read every line before you publish.

Who this is for

You have a website or landing page. Maybe AI helped build it. And it looks like every other site out there.

This is your designer's first pass, without the designer.

What you need

• Claude Code
• Node.js
• One page to check (one HTML file is best)

That's it.

Set it up

Step 1: Add it

One line. It drops the skill into Claude Code.

Step 2: Restart Claude Code

Close it. Open it again. Now it knows the skill.

Use it

Open Claude Code and say:

Use the hallmark skill to audit ./page.html

You get a list. Worst problems first:

CRITICAL  Purple gradient background      style.css:12   Use one solid color
CRITICAL  Made-up "50,000+ teams" line    index.html:48  Remove it or use a real number
MAJOR     Emoji used as icons             index.html:30  Use simple real icons
...

Then say: "Now redesign it."

It tells you which files it will change. It might ask for one mood word, like "warm" or "technical." Give it one.

Tip: point it at one file. Give it a whole folder and it stops to write design notes first, then waits for your OK.

If something goes wrong

Claude doesn't know the skill. You didn't restart. Close Claude Code and open it again.

It stopped and is waiting. You gave it a folder. Say yes, or point it at one file.

The new page says things you never said. Delete them before you publish.
