How do I stop my AI-generated app from looking AI-generated?
Give the agent a written design system instead of taste adjectives. The tell is not bad craft, it is defaulted craft: purple gradients, rounded cards, floating shadows, centered hero copy. Constraints remove them; nicer prompts do not.

Installable skill for Claude Code, Cursor, and Codex that enforces an anti-slop design ruleset on generated UI.

What to look for
- 01Does the tool take a design system as input — tokens, type scale, spacing, banned patterns — or does it just restyle?
- 02Does it name specific anti-patterns to remove? Vague instructions to make it beautiful produce a different default, not an intentional one.
- 03Can you re-run it and get the same answer? Consistency across screens is what reads as designed.
Common questions
- What actually makes an interface look AI-generated?
- Defaults, applied everywhere: violet-to-blue gradients, uniformly rounded cards with soft shadows, a centered hero with three feature columns, and emoji as iconography. Individually fine, together a signature.
- Is a design system overkill for a small project?
- One page of constraints is enough — a type family, a small colour set, a spacing unit, a radius, and a list of banned patterns. That page does more for the result than any amount of prompt tuning.
