Syncfusion® Agentic Blazor UI Builder Skill for AI Assistants

25 May 20269 minutes to read

Syncfusion® Agentic Blazor UI Builder is an AI-powered skill and companion agent that accelerates Blazor application development by transforming natural-language UI requirements into production-ready components using Syncfusion® Blazor UI libraries.

Integrated with your AI-powered IDE, it leverages deep knowledge of Syncfusion® components to deliver accurate and ready-to-use code.
By combining intelligent code generation with best practices, accessibility standards, and design-system consistency, Blazor UI Builder helps you rapidly build scalable dashboards and user interfaces without leaving your development workflow.

Prerequisites

Before installing Blazor UI Builder, ensure the following:

Requirement Description
Blazor Project Active Blazor WebAssembly or Blazor Server project (.NET 8+)
Microsoft .NET SDK 8.0 or later .NET CLI tools installed
Node.js version 18 or later npm package manager installed
Agent Package Manager (APM) Agent Package Manager installed. Installation Guidelines
Syncfusion License Commercial, Free Community, or Free Trial
Supported AI Agent / IDE A supported AI agent or IDE that integrates with Skills (VS Code, Cursor, Syncfusion® Code Studio, etc.)

Key Benefits

AI-Driven UI Generation

  • Converts prompts into complete Blazor components-not just snippets
  • Automatically selects appropriate Syncfusion® components and features
  • Produces structured, maintainable code

Component Usage & API Accuracy

  • Uses correct Syncfusion® component APIs
  • Injects required feature modules (paging, sorting, filtering, etc.)
  • Avoids unsupported or deprecated patterns

Patterns & Best Practices

  • Recommended component composition and Blazor lifecycle integration
  • Event handling aligned with Blazor standards
  • Secure and scalable coding patterns

Accessibility & Responsiveness

  • WCAG 2.1 AA–aligned output
  • Semantic HTML with ARIA support
  • Mobile-first responsive layouts

Design-System Integration

  • Supports Tailwind, Bootstrap, Material, or custom themes
  • Ensures consistent Syncfusion® styling and theme usage

Installation

Before installing Blazor UI Builder, ensure that APM (Agent Package Manager) is installed and available in your environment.

Verify APM Installation

Run the following command to confirm APM is installed:

apm --version

Install the Syncfusion® Agentic Blazor UI Builder package using APM

Use the APM CLI to install the Blazor UI Builder skill for your preferred environment:

apm install syncfusion/blazor-ui-builder -t copilot
apm install syncfusion/blazor-ui-builder -t cursor
apm install syncfusion/blazor-ui-builder -t codex
apm install syncfusion/blazor-ui-builder -t claude

After installation, the following artifacts are added to your project for the GitHub Copilot target:

  • .agent/skills/ – contains the skill files
  • .github/agents/ – contains the agent configuration

Refer to the documentation for details about supported deployment targets.

For Syncfusion® Code Studio, use the Copilot command above to install the Blazor UI Builder.

How the Syncfusion® Agentic Blazor UI Builder Skill Works

  1. Intent Analysis - Parse the user’s prompt to identify component types and high-level layout intent.
  2. Project Detection - Automatically detects project framework, package manager, and existing themes.
  3. Component Mapping - Map intent to Syncfusion® components and required feature modules.
  4. Theming & Design System
    Load required theming guidelines and confirm key design choices:
    • CSS framework (Tailwind, Bootstrap, Material, or Greenfield(custom theme)). If no themes detected in the existing project, Greenfield and Syncfusion Tailwind3 theme are shown as the default option-proceed with this or change the theme as preferred.
    • Syncfusion theme (Tailwind3, Bootstrap5, Material3, fluent2)
    • Light and Dark Mode
    • Core design basics (colors, spacing, typography, responsiveness, accessibility)
  5. Code Generation - Produce C# Blazor components, parameter interfaces, and CSS/styling scaffolding.
  6. Dependency Management - Recommend or install required Syncfusion® packages and peer dependencies.
  7. Validation - Run accessibility and basic security checks, request confirmation for changes.
  8. Code Insertion - Create files or patch existing files following project structure and conventions.

Key enforcement points:

  • Adds correct theme and CSS imports for chosen Syncfusion® themes
  • Injects only the feature modules required by generated components
  • Generates semantic HTML with ARIA attributes and keyboard support
  • Avoids unsupported or deprecated API usages for Syncfusion® components

The assistant handles most stages automatically and may request confirmation where required.

Generate UIs using the Agentic UI Builder

After installing Blazor UI Builder with APM, the relevant agent and skill files are added to your project under:

  • .agent/skills/ (skill files)
  • .github/agents/ (Blazor UI builder agent configuration)

To start using the skill:

  1. Open your supported IDE.
  2. In the chat panel, select the syncfusion-blazor-ui-builder agent from the Agent dropdown.
    Set Agent
  3. Start prompting the agent with a clear description of your UI requirements.

Examples Prompts:

Authentication

Create a login page with the Tailwind 3 theme using a centered card layout containing email and password input fields with validation. Include a “Remember Me” checkbox, a forgot password link, and a primary login button. Add a secondary “Create Account” button below. Ensure the layout is responsive and works on mobile, tablet, and desktop.

Admin Dashboard

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.

  1. Generated code follows best practices with accessible, semantic HTML, responsive mobile-first layouts, strong C# typing, and built-in security measures such as input validation and avoidance of embedded secrets.

Best Practices

Follow these guidelines to get the most out of UI Builder and ensure high-quality production-ready result:

  • Stay consistent - Maintain consistent file organization, naming conventions, and coding standards throughout your project.
  • Use advanced AI models - For best results, use Claude Sonnet 4.6 or higher capability models to produce better code quality and more accurate implementations.
  • Review all content and assets before production - Replace any placeholder images or icons (e.g., from emoji sets) with your brand assets. Also validate the logic, security, and compatibility with your existing code before deployment.

Troubleshooting

  • APM installation failure: Refer to this documentation

  • Skills not loading: Ensure the .agent/ and .github/agents/ folders exist in your project and that the skill was installed successfully using APM. Verify that the correct agent is selected from the Agent dropdown in your IDE.

  • Component not rendering: Retry generation using the specific component skill to resolve the issue, and ensure required Syncfusion® packages and themes are properly configured.

  • Syncfusion license banner appears: Use the licensing skill to correctly register and validate your Syncfusion® license key in the application.

FAQ

Which agents/IDEs are supported?
Any Skills-compatible agent that reads local skill files (Code Studio, VS Code, Cursor, etc.).

Are skills loaded automatically?
Yes. Supported agents automatically load relevant skills based on your query.

Can I customize the generated styles?
Yes - the skill supports choosing Tailwind, Bootstrap, Material, or a custom theme; generated components include clear integration points for style adjustments.

Does it modify files automatically?
The skill proposes changes and requires confirmation for insertion; automatic dependency installation may be offered depending on agent permissions.
