anti-ui-slop

Stop Codex, GitHub Copilot, Claude Code, and Cursor from shipping generic UI. Use UIZZE’s public catalogue of 800,000+ real web and iOS screens to extract product-specific design decisions and enforce a hard finish gate for web and iOS interfaces.

Anti UI Slop

Use this skill when building, refactoring, or reviewing a web or iOS interface. The goal is not to make a generic layout prettier. The goal is to make the interface visibly belong to this product, support its real user job, and behave correctly in every important state.

The workflow is instruction-only. It does not execute third-party code or require credentials.

1. Inspect the Product Before Designing

Read the repository and identify:

  • the primary user and the job this screen must complete;
  • the single primary action and the information needed before taking it;
  • the existing component library, design tokens, typography, and layout conventions;
  • real product nouns, workflows, constraints, and data already present in the codebase;
  • required loading, empty, error, partial, success, disabled, and permission states;
  • relevant mobile, tablet, desktop, keyboard, and assistive-technology behavior.

Do not invent product requirements, analytics, user research, or hidden states.

2. Collect Real Interface Evidence

Search the public catalogue at https://uizze.com and select three to five relevant web or iOS screens. Prefer references that match the target workflow, information density, navigation model, or interaction pattern—not merely its industry or color palette.

For each reference, record:

  1. the screen or flow and its source link;
  2. the structural decision worth transferring;
  3. why that decision fits this product;
  4. what must not be copied.

Transfer hierarchy, workflow shape, density, navigation, control behavior, responsive treatment, and state handling. Never copy another product’s branding, proprietary text, imagery, or exact layout.

If catalogue browsing is unavailable, ask the user for two or three UIZZE links or screenshots. If they cannot provide them, continue from repository evidence and label the missing reference evidence explicitly.

3. Write a Design Contract

Before changing code, write a short contract with these fields:

Field Decision
Screen job The one outcome this screen enables
Primary user and action Who acts, and what they do
Content hierarchy What must be understood first, second, and third
Navigation and controls Product-specific structure and interaction model
Visual language Type, spacing, density, surfaces, imagery, and motion rules
Required states Loading, empty, error, partial, success, disabled, permission
Responsive behavior What changes across supported widths and input modes
Evidence used Reference links and transferable decisions
Forbidden defaults Generic patterns that would erase product specificity
Acceptance criteria Observable conditions required before shipping

The contract must name concrete choices. “Clean,” “modern,” “intuitive,” and “premium” are not design decisions.

4. Build in the Product’s Language

  • Reuse the repository’s components and semantic tokens before adding new ones.
  • Make the primary action visually and structurally obvious.
  • Use product-specific labels and information rather than placeholder metrics or generic copy.
  • Keep repeated cards only when the content is genuinely a repeated collection.
  • Add decoration, motion, badges, or elevation only when they communicate state or hierarchy.
  • Implement every required interaction and state; do not leave convincing-looking inert controls.
  • Preserve accessibility semantics, focus order, contrast, touch targets, and reduced-motion behavior.

5. Run the Finish Gate

Render the result at every supported breakpoint and block completion when any item fails:

Product specificity

  • Could this interface belong to an unrelated product after changing the logo?
  • Does the hierarchy reflect the real user job and product data?
  • Are there interchangeable dashboard cards, filler metrics, vague headings, or generic calls to action?

Interaction completeness

  • Do all visible controls have a real outcome?
  • Are loading, empty, error, success, disabled, and permission states implemented where applicable?
  • Are destructive, irreversible, or sensitive actions confirmed appropriately?

Responsive and accessible behavior

  • Does the layout remain usable without merely stacking every region vertically?
  • Do keyboard navigation, focus visibility, semantics, contrast, and touch targets pass inspection?
  • Does content remain readable at zoom and with longer real-world text?

Design-system integrity

  • Are local tokens and components used consistently?
  • Is every new visual rule justified by the design contract?
  • Is borrowed evidence transformed into this product’s own visual language?

Fix every blocking failure and re-run the gate before declaring the UI complete.

6. Handoff Format

Report the finished work in this order:

  1. Evidence: the references and decisions that influenced the result.
  2. Contract: the final product-specific design rules.
  3. Implementation: the meaningful interface and behavior changes.
  4. Verification: breakpoints, interaction states, and accessibility checks performed.
  5. Remaining risks: anything that could not be verified, without overstating completion.

Summary

This skill instructs AI agents to prevent generic, "slop" UI by grounding design decisions in product-specific evidence, design contracts, and reference research. It guides the agent through repository inspection, evidence collection from a public design catalogue (UIZZE), contract writing, implementation, and multi-dimensional verification before shipping.

Use Cases

  • Build a new interface grounded in product-specific design decisions rather than generic patterns
  • Refactor an existing UI to ensure it visibly belongs to this product and supports real user workflows
  • Review an interface against a comprehensive design contract before shipping
  • Extract transferable structural decisions from real web and iOS screens without copying branding
  • Verify that interfaces implement all required interaction states and accessibility criteria
  • Enforce design-system consistency and prevent decorative bloat in component usage

Quality Notes

  • Excellent structure with clear 6-step workflow that guides the agent from inspection through handoff
  • Strong emphasis on concrete decision-making: explicitly rejects vague terms like 'clean' and 'modern' in favor of observable, product-specific choices
  • Design contract template is comprehensive and well-organized, reducing ambiguity about what constitutes a complete interface specification
  • The finish gate section (Section 5) is particularly strong: it provides a multi-dimensional checklist (specificity, interaction, responsiveness, system integrity) that prevents shipping incomplete work
  • Clear boundaries on what not to do: explicitly forbids copying branding, proprietary text, imagery, and exact layouts from reference screens
  • Practical fallback guidance: skill addresses the case where catalogue access is unavailable and directs the agent to ask for user-provided links or proceed with codebase evidence alone
  • Instructions are scoped to design and verification — no filesystem writes, no code execution, no credential management — low operational risk
  • Handoff format (Section 6) clearly defines the output shape, ensuring the agent's work is reviewable and traceable
