How Loops Works

The core idea

Most AI coding tools have a gap: the AI writes code, but it can’t see whether it actually worked. You’re the one who has to check, report back, copy-paste errors, and go back and forth.

Loops closes that gap. Your Webflow staging site sends live logs directly back to Claude — every console message, every error, every success confirmation. Claude can see exactly what’s happening in the browser without you doing anything.

That’s the whole product. A closed feedback loop.

The loop, step by step

Here’s what happens when you say “Add fade-in animations to the portfolio grid”:

1. Claude writes the code

Based on your description and your Webflow class names, Claude writes the JavaScript.

2. The code goes live on staging

Claude pushes the code to your staging site. The page reloads automatically — you don’t need to refresh or do anything.

3. Your site sends logs back

This is the key part. Your staging site captures everything that happens:

• Success messages: "Fade-in initialized on 6 elements"
• Errors: "Cannot find element .portfolio_grid"
• Warnings, network failures, unhandled exceptions — everything

These logs are sent back to Claude within seconds.

4. Claude reads the logs

Claude sees the real result. Not a guess — the actual output from your actual site. It knows whether the code worked, how many elements it found, or exactly what went wrong.

5. If something’s off, Claude fixes it

Say Claude used the wrong class name. The log comes back: "Cannot find element .portfolio_grid". Claude reads that, realizes the class is actually .portfolio-grid_wrapper, rewrites the code, and pushes again. Your site reloads, new logs come back: "Fade-in initialized on 6 elements". Done.

You didn’t have to do anything. You didn’t paste an error message. You didn’t describe what went wrong. The loop handled it.

Why this matters

Without the loop, AI coding is a guessing game. The AI writes something, you check it, you report back. With Loops:

• Claude can console.log to debug, just like a developer would — and actually read the output
• Errors are caught automatically — JavaScript errors, missing elements, network failures
• Each iteration takes seconds, not minutes of back-and-forth
• Claude self-corrects before you even notice something was wrong

It’s the difference between asking someone to build something blindfolded vs. with their eyes open.

What about your live site?

The feedback loop only runs on your .webflow.io staging domain. The logs, the auto-reload, the error catching — none of that happens on your production site with a custom domain. Zero performance impact.

Your custom code (animations, data fetching, DOM manipulation, all of it) does run on production — it’s just regular script embeds. But the development tooling is strictly staging-only.

The snippets

The two small snippets that Claude asks you to paste in Webflow are what make this loop work:

• The Site Settings snippet captures logs and listens for reload signals from Claude
• The page snippets load your custom code

They’re the bridge between Claude and your staging site. Paste them once, forget about them.
