SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

It closes the gap between product requirements and front-end implementation by producing evidence-backed UX discovery artifacts and developer-ready UI specifications that include wireframes, user flows, accessibility checks, and component annotations.

Core Features & Use Cases

  • Discovery mode: audit existing screens, map user flows, produce Excalidraw wireframes, and generate a structured UI spec that feeds acceptance criteria and architecture decisions.
  • Delivery mode: validate or adjust wireframes against technical constraints, finalize UI specs for fe-dev with component names, props, and interaction details.
  • Accessibility & design system enforcement: run WCAG 2.1 AA checks, require design system updates as prerequisites, and insist on evidence (file paths/excerpts) for claims.
  • Use case: a PM requests UX discovery for a new feature; the agent produces flow diagrams, .excalidraw wireframes, an annotated UI spec, and accessibility checklist before the feature is broken down for implementation.

Quick Start

Ask the UX Designer to perform discovery for "Add pagination" in mobile mode, audit existing screens, produce Excalidraw wireframes, and deliver a developer-ready UI spec with component names and props.

FAQPage Schema
How do I generate developer-ready UI specs from product requirements?

To generate developer-ready UI specs, use a UX discovery workflow that audits existing screens, maps user flows, and outputs annotated component specifications. This process closes the gap between product requirements and front-end implementation.

Can I create Excalidraw wireframes for mobile and web features automatically?

Yes, you can create Excalidraw wireframes for mobile and web features. The workflow generates .excalidraw outputs by reviewing existing screens and design tokens, producing wireframes suitable for product discovery and sprint delivery phases.

What is included in a UX accessibility audit for UI specifications?

A UX accessibility audit for UI specifications includes WCAG 2.1 AA checks on wireframes and components. It requires evidence-based review of existing screens to ensure design system compliance before front-end development begins.

How do I map user flows during product discovery?

Map user flows during product discovery by auditing existing screens and applying evidence-based review. This produces structured flow diagrams and UI specs that feed acceptance criteria and architecture decisions for new features.

Do I need existing design tokens to produce UI specs and wireframes?

Yes, existing design tokens are required. The workflow insists on design system updates as prerequisites and requires evidence like file paths or excerpts for claims, ensuring component annotations align with established tokens.

What is the best way to validate wireframes against technical constraints for sprint delivery?

Validate wireframes against technical constraints in delivery mode by adjusting designs and finalizing UI specs for front-end developers. This ensures component names, props, and interaction details are implementation-ready.
