Matrix UI-Engine

Matrix UI-Engine Skill v2.0

This skill empowers the agent to act as a high-fidelity web application architect, converting visual designs into production-ready code aligned with the Matrix Design System, with integrated UI issue detection and correction.

Capabilities

1. Visual Analysis: Interprets screenshots, Figma URLs, and design references to identify layouts, typography, and color schemes.
2. Token Mapping: Automatically maps identified styles to the Matrix Design Tokens.
3. Template Synthesis: Generates modular React/Next.js components using Tailwind CSS and saved Matrix utilities.
4. Registry Management: Categorizes and enters new components into the Template Registry.
5. UI Validation: Detects and auto-corrects scaling, clipping, overflow, button sizing, and text readability issues.
6. Component Library: Leverages the DesignTokens.tsx reusable component library.

GitHub Resource Integrations

The following resources are integrated into the design system and inform all UI decisions:

Resource	Integration	Token Prefix
OpenAI Apps SDK UI	Alpha layers, semantic surfaces/borders, card patterns, accessible components via Radix primitives	--m-alpha-*, --m-border-*
AG-UI Protocol	State colors for streaming/thinking/complete/error, event-based UI patterns	--m-state-*
Onyx	High-density dashboard patterns, agent cards, RAG status displays	MetricCard, SurfaceCard
Ink	Terminal-inspired progress bars, spinners, task lists, terminal color palette	--m-terminal-*, ProgressBar, Spinner, TaskList
Avalonia	Cross-platform theming architecture, dark mode token system	Theme structure
Open Targets	Data-dense visualization patterns, sparkline micro-charts	MetricCard density

Installed Packages (from Resources)

These packages were extracted from the GitHub resources and installed:

• radix-ui — Accessible primitives (Dialog, Tooltip, Select, Accordion)
• react-syntax-highlighter — Code block rendering with themes
• usehooks-ts — Premium hooks (useMediaQuery, useLocalStorage, useDebounce)

Operational Workflow

1. Reception

When a user sends a UI image or design link:

• Trigger "Sage Vision" mode.
• Extract spatial relationships and stylistic motifs.
• Cross-reference against the GitHub resource pattern library.

2. Implementation

• Create a new .tsx file in core/templates/.
• Use the tokens.css and base.css as the only source of truth for variables.
• Use the DesignTokens.tsx component library for standard UI primitives (Badge, SurfaceCard, ProgressBar, etc.).
• Ensure the component is responsive (mobile-first) and accessible.

3. UI Validation (Automated)

Before finalizing, run validation checks (via matrix-capture.js):

• Overflow Detection: No text/elements clipping outside containers
• Touch Target Sizing: All interactive elements ≥ 44px (per --m-min-touch-target)
• Font Readability: No text below --m-min-font-size (10px)
• Viewport Scaling: Content fits without horizontal scroll at 320px–2560px
• Button Sizing: Consistent padding, adequate hit areas
• Z-index Stacking: No elements hidden behind overlays

4. Verification

• Verify that the generated code is clean, documented, and follows the Matrix "Sleek" aesthetic.
• Notify the user of the new template ID.

Core Directives

• Aesthetics First: Never generate generic components. Use gradients, glassmorphism, and micro-animations.
• Interoperability: Components must be drop-in ready for nexus, reflect, or any Matrix sub-app.
• Privacy First: Prefer local assets and standard icons over external dependencies.
• Semantic Tokens: Always use --m-* tokens instead of hardcoded colors.
• Corrective UI: Proactively detect and fix sizing, scaling, and overflow issues.
