Anti-Generic UI

Coding agents converge on the same look because they trained on the same templates (Tailwind UI, shadcn examples, Vercel starters). This skill makes you notice that default and deliberately leave it.

When to use

• Before building UI: set a design direction so you don't reach for defaults.
• After generating UI: audit against the tells below and polish.
• When the user says it looks "generic", "AI-generated", "flat", or "like every

other SaaS site".

The tells (if you see these, it's the generic look)

• Type: Inter / Roboto / Arial for everything; one weight; no display face.
• Color: Tailwind's default ramp untouched — indigo-600, slate-900,

gray-500 text on white; a blue→violet gradient on the hero.

• Layout: the skeleton hero → 3-column feature grid → logo cloud → pricing →

FAQ → footer, every section a centered max-w-7xl with the same vertical rhythm.

• Depth: cards inside cards inside cards; border border-gray-200 +

shadow-sm on everything; uniform rounded-lg.

• Motion: bounce/elastic easing, 500ms+ transitions, everything fades up on

scroll the same way.

• Filler: emoji as feature icons, gradient text on every heading, lorem-ish

"Empower your workflow" copy.

Banned by default (require a reason to use)

• Inter/Roboto/Arial as the primary brand face.
• Untouched Tailwind indigo/slate/gray as the brand palette.
• Pure black (#000) text/bg and pure gray text on colored backgrounds.
• Card nesting more than one level deep.
• bounce / elastic / back easing for UI transitions.
• The default hero→features→pricing skeleton with no point of view.
• Gradient text on more than one element per viewport.

Positive rules (do this instead)

1. Pick a real palette. Choose a hue that isn't in the default scale, build a

ramp with a consistent chroma, and define a non-neutral surface tone (warm off-white, cool near-black) instead of #fff/#000. One accent, used sparingly, beats three gradients.

1. Pair type with intent. A distinctive display face for headings + a clean,

readable text face for body. Set a type scale (e.g. 1.25 ratio) and use weight and size — not color — for hierarchy.

1. Establish rhythm. One spacing scale (4/8-based), consistent line-length

(~60–75ch for body), and a vertical rhythm you actually keep.

1. Depth through light, not boxes. Prefer layered, soft shadows and subtle

contrast over border + shadow-sm on every card. Flatten nesting.

1. Motion with purpose. Short (120–240ms), eased (ease-out /

custom cubic-bezier), and tied to a state change. Respect prefers-reduced-motion.

1. One signature move. Give the design a single memorable element — a custom

cursor, a distinctive border treatment, an unexpected accent — so it isn't anonymous.

Process: critique → audit → polish → harden

Run as separate passes, like a designer would — not one "make it pretty" step.

1. Critique — describe what's generic about the current screen in concrete

terms (name the font, the indigo, the nesting). No fixes yet.

1. Audit — check against Banned by default and the tells. List violations.
2. Polish — apply the Positive rules: palette, type, spacing, depth, motion,

signature. One concern at a time.

1. Harden — verify contrast (WCAG AA), reduced-motion, responsive at 360px,

focus states, and that nothing regressed to a default.

Common rationalizations

Red flags

• A theme/palette that is byte-for-byte the framework default.
• rounded-lg border shadow-sm repeated on every container.
• Headings differentiated only by color, not weight/size/face.
• Animations all 500ms with the same easing.
• Three or more gradients competing in one viewport.

Verification

• [ ] Primary font is not Inter/Roboto/Arial (or has an explicit reason).
• [ ] Palette is not the untouched framework default; surfaces aren't pure #fff/#000.
• [ ] No card nesting beyond one level.
• [ ] Transitions ≤ ~240ms, eased, and gated behind prefers-reduced-motion.
• [ ] Text contrast passes WCAG AA; visible focus states exist.
• [ ] The screen has at least one intentional, memorable signature element.
