About prompt

A system prompt designed to instruct a generative AI model to act as a Generative UI Architect. The prompt establishes core principles such as component-first thinking, design systems native approach, interaction completeness (accounting for all UI states), responsive by default, and accessibility as architecture (WCAG 2.2 AA). It specifies a structured output format including design rationale, component breakdown, state matrix, token mapping, code (React/TypeScript preferred), and accessibility notes. The prompt also enforces constraints like avoiding placeholder text, semantic HTML, and purposeful animations. It is hosted as an open-source file in the ai-boost/awesome-prompts GitHub repository.

Key Features

Component-first thinking: break UI into atomic, reusable components with clear props and states.

Design systems native: respect tokens for spacing, color, typography, elevation, motion; no hard-coded values.

Interaction completeness: account for empty, loading, error, success, and edge states.

Responsive by default: layouts adapt across breakpoints using CSS Grid and Flexbox.

Accessibility as architecture: enforce WCAG 2.2 AA with semantic HTML, focus management, ARIA, and keyboard-navigable flows.

Structured output: design rationale, component breakdown, state matrix, token mapping, code (React/TypeScript preferred), accessibility notes.

Constraints: use realistic copy, avoid div soup, animations via CSS transforms/opacity only.

Optimized for generative UI platforms like v0, Bolt, Lovable with copy-paste-ready blocks.

Pros & Cons

Pros

Promotes structured, production-quality UI design with explicit state handling.
Enforces accessibility standards (WCAG 2.2 AA) by design.
Output includes complete code with prop interfaces and realistic data fixtures.
Encourages use of design-system tokens, avoiding arbitrary values.
Supports multiple frameworks (React/TypeScript, Vue, Svelte, SwiftUI).
Reduces hallucinated placeholder content and semantic HTML violations.
Open source and freely available on GitHub.

Cons

Requires a generative AI model capable of following detailed instructions.
May produce lengthy outputs due to the comprehensive output format.
Not a standalone tool; requires integration with an AI model or platform.
Tone may be too prescriptive for creative prototyping phases.

Best For

Generating user interface components with full state coverage and accessibility compliance.Designing design-system-aligned UI from natural language descriptions.Creating responsive layouts with semantic HTML and proper token mapping.Auditing or improving existing generative UI outputs for production readiness.Teaching and enforcing best practices in generative UI design.

FAQ

What is the Generative UI Architect prompt?

It is a system prompt hosted on GitHub (ai-boost/awesome-prompts) that instructs an AI to act as a Generative UI Architect. It defines core principles, output format, and constraints for designing production-grade user interfaces.

What programming languages or frameworks does the prompt support?

The prompt prefers React/TypeScript but also supports Vue, Svelte, and SwiftUI when requested.

Does the prompt enforce accessibility?

Yes, it enforces WCAG 2.2 AA as a minimum, including semantic HTML, focus management, ARIA, color-contrast safe palettes, and keyboard-navigable flows.

Is this tool free to use?

Yes, the prompt is open source and freely available in the ai-boost/awesome-prompts GitHub repository.

What output format does the prompt expect?

The prompt specifies six sections: Design Rationale, Component Breakdown, State Matrix, Token Mapping, Code (with prop interfaces and data fixtures), and Accessibility Notes.
