tessl review fix ./SKILL.mdThis document exists to teach you how to act as non-Codex as possible when building UI.
Codex UI is the default AI aesthetic: soft gradients, floating panels, eyebrow labels, decorative copy, hero sections in dashboards, oversized rounded corners, transform animations, dramatic shadows, and layouts that try too hard to look premium. It's the visual language that screams "an AI made this" because it follows the path of least resistance.
This file is your guide to break that pattern. Everything listed below is what Codex UI does by default. Your job is to recognize these patterns, avoid them completely, and build interfaces that feel human-designed, functional, and honest.
When you read this document, you're learning what NOT to do. The banned patterns are your red flags. The normal implementations are your blueprint. Follow them strictly, and you'll create UI that feels like Linear, Raycast, Stripe, or GitHub—not like another generic AI dashboard.
This is how you Uncodixify.
Think Linear. Think Raycast. Think Stripe. Think GitHub. They don't try to grab attention. They just work. Stop playing hard to get. Make normal UI.
Everything you are used to doing and is a basic "YES" to you.
No oversized rounded corners.
No pill overload.
No floating glassmorphism shells as the default visual language.
No soft corporate gradients used to fake taste.
No generic dark SaaS UI composition.
No decorative sidebar blobs.
No "control room" cosplay unless explicitly requested.
No serif headline + system sans fallback combo as a shortcut to "premium."
No Segoe UI, Trebuchet MS, Arial, Inter, Roboto, or safe default stacks unless the product already uses them.
No sticky left rail unless the information architecture truly needs it.
No metric-card grid as the first instinct.
No fake charts that exist only to fill space.
No random glows, blur haze, frosted panels, or conic-gradient donuts as decoration.
No "hero section" inside an internal UI unless there is a real product reason.
No alignment that creates dead space just to look expensive.
No overpadded layouts.
No mobile collapse that just stacks everything into one long beige sandwich.
No ornamental labels like "live pulse", "night shift", "operator checklist" unless they come from the product voice.
No generic startup copy.
No style decisions made because they are easy to generate.
No Headlines of any sort
<div class="headline">
<small>Team Command</small>
<h2>One place to track what matters today.</h2>
<p>
The layout stays strict and readable: live project health,
team activity, and near-term priorities without the usual
dashboard filler.
</p>
</div>This is not allowed.
<small> headers are NOT allowed
Big no to rounded spans
Colors going towards blue — NOPE, bad. Dark muted colors are best.
Anything in the structure of this card is a BIG no.
<div class="team-note">
<small>Focus</small>
<strong>
Keep updates brief, blockers visible, and next actions easy to spot.
</strong>
</div>This one is THE BIGGEST NO.
If a UI choice feels like a default AI UI move, ban it and pick the harder, cleaner option.
Colors should stay calm, not fight.
