title: "Why the clean layout still failed the customer's first check"

The draft looks finished in the review meeting. The layout is clean and the wording reads well. Then it misses the one requirement the customer will notice first.

That is the trap with AI-assisted design. A result can look finished while missing the exact details that make it work for real people. Looking finished and working for this case are two different things.

## Why a good-looking result fools a review

The AI builds a result from patterns, so it comes out plausible. Plausible means it resembles the usual answer. Whether it is correct depends on a different check: laying the result next to the requirements, details and edge conditions that apply to your case.

## Write the requirements down first

Before anyone reviews the result, write down the requirements that cannot be negotiated. Put in the details that are easy to miss because the ordinary case looks fine. Those are the exact wording, the visual rules, the source materials, and the conditions at the edges, where things behave differently from the middle.

## What the AI does and what a person does

The AI is useful once that written list exists. Give it the list and the proposed result, and it can compare them. It flags the gaps and points out edge conditions nobody tested, and a person then reviews each of those.

The people still make the calls. They set the acceptance criteria, judge the gaps, and decide whether the result is ready. A polished draft is something to inspect. It is not approval.

Before you review the next AI-assisted design, write down what it must meet, including the exact wording, the visual rules and the edge conditions. Until a person has judged the gaps against that list, a design that looks finished is not approved.
