An agent built this in under a minute. It looks finished.
The skill asks four questions in order: Why, Flow, Feel, Ship. It starts with whether the screen does its job, because polish can’t fix that.
LGTM means it looks good to the developer. LGTU is a free skill that asks whether it looks good to the people who’ll use it, and gives your agent a senior designer’s verdict before you ship.
It reviews what you built the way a senior designer would, and ends with a verdict. Here’s a screen your agent might have built. Scroll, and watch it get reviewed.
Pebble brings your tasks, people and priorities together in one place, so you can focus on what matters most.
The skill asks four questions in order: Why, Flow, Feel, Ship. It starts with whether the screen does its job, because polish can’t fix that.
A visitor can’t tell which one is the next step, so they hesitate.
The fix: one filled button for the next step. The demo becomes a quiet link. “Learn more” goes.
After reading it, you still don’t know what Pebble does.
The fix: start from the visitor’s problem, in their words. Plan your team’s week in five minutes.
Three badges compete for attention and the cards sit at three heights. It reads as the average of every landing page.
The fix: one left edge, one radius, one row of cards. The badges go.
The small grey line looks like about 2.5:1 (estimate). Many people can’t read it comfortably.
The fix: a calm surface and body text above 4.5:1. Nothing depends on the gradient.
Working well: the card copy is short and easy to scan. Keep it.
Ten principles under four questions you can remember: Why, Flow, Feel, Ship. Each one starts with a stance, then asks what a senior designer would ask.
Should this exist? A Why problem makes polish irrelevant, so the skill asks it first.
Read the full skill, with every question and the red flags agents tend to produce.
For you if…
It isn’t for you if you want a finished redesign done for you, or pixel-perfect brand work. It reviews and steers; you and your agent make the changes.
Try it on one screen. If it doesn’t tell you something you didn’t know, delete it. Nothing is hidden: you can read every line before you sign up.
Under four questions: Why, Flow, Feel and Ship. Purpose before pixels.

Looks Good To Users. Developers approve code with LGTM, “looks good to me”. LGTU asks the question that matters before you ship: does it look good, and work, for the people using it?
Yes. Free for you and your agents. Share it as it is, with a link back here.
Claude, Cursor and Codex: any agent that reads skill folders. Show it a screenshot, a page, a Figma frame or code.
The skill is a text file that runs inside your own agent. It doesn’t send your screens anywhere by itself.
No. It gives you the questions a designer would ask, so you catch the obvious things and know when you need a real one.
