```
## How It Works
The ASP.NET Core UI Builder uses an **8-stage AI orchestration workflow** that transforms your requirements into production-ready components.
**Stage 1: Intent Analysis**
Parse the user's natural language query to identify component types, layout intent, and desired functionality.
**Stage 2: Project Detection**
Automatically detect the project framework (MVC, Razor Pages), .NET version, and existing theme configuration.
**Stage 3: Component Mapping**
Select appropriate Syncfusion components and their required icons based on the identified intent.
**Stage 4: Theming & Design System**
Lock in design system decisions including CSS framework, Syncfusion theme (Bootstrap5, Tailwind, Material3), color modes (light, dark) colors, spacing, typography upon users confirmation.
**Stage 5: Code Generation**
Produce Razor view components, Tag Helpers components with full model binding and CSS/styling scaffolding.
**Stage 6: Dependency Management**
Install required Syncfusion NuGet packages and their dependencies.
**Stage 7: Validation**
Run WCAG accessibility checks, security scans, and performance audits. Request approval before code insertion.
**Stage 8: Code Insertion**
Create new files or patch existing ones following the project's structure and coding conventions.
## Usage
Choose the `syncfusion-aspnetcore-ui-builder` agent in the AI chat panel and invoke the skill through your AI assistant by describing what you want to build:
```
Create a CMS Admin Dashboard UI featuring a collapsible sidebar with navigation items for Dashboard, Content, Users, Analytics, and Settings; a top header (AppBar) showing the title “CMS Admin Dashboard” on the left and a user name with profile icon on the right; and a main content area that includes three compact summary cards in a single row displaying Total Content, Total Users, and Active Sessions (each card showing a label, relevant icon, prominent count value, and percentage change from last month), followed by a “Content Management” section with a filterable and data grid containing columns for Title, Author, Status, Date, and Actions (with edit and delete buttons), and finally two charts displayed side by side—a bar chart titled “Content Over Time” and a donut chart titled “Content by Category”—using realistic sample data for both the grid (10–12 rows) and the charts.
```
Generated code follows best practices with accessible, semantic HTML, responsive mobile-first layouts, strong model binding, and built-in security measures such as input validation and avoidance of hardcoded secrets.
## Best Practices
- Maintain consistency in file structure, naming, and coding standards.
- Use advanced AI models (e.g., Claude Sonnet 4.6+) for better code quality.
- Review everything before production—replace placeholders and verify logic, security, and compatibility.
