Syncfusion Angular UI Builder

Overview

The Syncfusion Angular UI Builder skill is a frontend-only Angular component generator that orchestrates an AI agent through 8 stages to generate production-ready UI components powered by Syncfusion.

What This Skill Does

✅ Generates:

• Angular components (.ts with .html templates and .css)
• CSS stylesheets (CSS Modules, Tailwind classes, inline styles)
• TypeScript interfaces for component properties, state, and event handlers
• Syncfusion component integration with correct imports and selectors
• Client-side form validation logic
• WCAG 2.1 AA accessibility markup (ARIA attributes, semantic HTML)
• Responsive CSS with mobile-first breakpoints
• Component exports and barrel files

❌ Does NOT Generate:

• Backend code (API routes, server handlers, middleware)
• Database schemas or ORM models
• Authentication/authorization logic
• Server-side validation
• Routing configuration
• Environment secrets or infrastructure config

When to Use

✅ USE this Skill for:

• Full UI builds with 3+ Syncfusion components
• Design system decisions required (CSS framework, colors, spacing, typography)
• Complete pages or dashboards from scratch
• WCAG 2.1 AA validation for complex layouts
• Multi-stage workflows requiring design → code → validate
• Team collaboration on larger component projects
• Examples:
  • Building a complete Angular admin dashboard
  • Designing a multi-form wizard interface
  • Creating a full data management portal with multiple sections
  • Implementing a complex dashboard with multiple views and charts

❌ DO NOT USE this Skill for:

• ✋ Configuring a single component (use component skill directly)
• ✋ Quick implementation questions (use component skill directly)
• ✋ Component tutorials or how-tos (use component skill directly)
• ✋ Troubleshooting component issues (use component skill + diagnostic protocol)
• ✋ Backend/API code (out of scope)
• ✋ Non-Syncfusion Angular questions (use general Angular help)

Quick Start

Prerequisites

1. Active Angular project (Angular 15+, created with Angular CLI)
2. Node.js 18+ and npm/yarn/pnpm installed
3. Syncfusion Angular components library (auto-installed if missing):

Basic Usage

Example 1: Generate a Login Form

User: "Create a login form with email, password, and remember me checkbox"

Skill executes:
  → Stage 1: Identifies login form component type
  → Stage 2: Detects project structure (Angular, TypeScript, etc.)
  → Stage 3-4: AI creates optimal component-mapping.json → maps to Syncfusion components
  → Stage 5: Generates LoginForm.component.ts with validation
	→ Stage 6: Installs dependencies
  → Stage 7: Validates WCAG 2.1 AA compliance
  → Stage 8: Inserts code into project

Output:
  ✓ components/LoginForm/login-form.component.ts
  ✓ components/LoginForm/login-form.component.html
  ✓ components/LoginForm/login-form.component.css

Example 2: Generate a Dashboard

User: "Build a dashboard with customer overview, recent orders table, and sales chart"

Output:
  ✓ components/dashboard/dashboard.component.ts (with Syncfusion DataGrid)
  ✓ components/customeroverview/customeroverview.component.ts
  ✓ components/recentorders/recent-orders.component.ts (with Syncfusion DataGrid)
  ✓ components/saleschart/sales-chart.component.ts (with Syncfusion ChartComponent)
  ✓ Mock data included (useState with sample data)
  ✓ Responsive design (mobile-first, grid layout)
  ✓ Dark mode support with design tokens
  ✓ Full accessibility compliance (WCAG 2.1 AA)

How It Works: 8-Stage AI Orchestration (Stateless)

The skill orchestrates 8 stages of pure AI reasoning with two user decision points.

Key Architecture:

• Stateless design: Conversation history maintains state
• Pure AI reasoning: Each stage reads guidance docs, analyzes context, makes decisions
• 1 user decision gates: Stage 4 (theme confirmation)
• 7 fully automated stages: 1, 2, 3, 5, 6, 7, and final code insertion
• Dedicated theming stage: Stage 4 locks design system before code generation

User Request
    ↓
[Stage 1: Intent Analysis] 
  AI reads query → identifies component type & features
    ↓
[Stage 2: Project Detection]
  AI scans project → detect framework, language, CSS strategy, preferences
    ↓
[Stage 3: Layout Analysis & Component Mapping] 
  AI analyzes requirements → creates optimal component-mapping.json
  AI maps to specific Syncfusion components (3+ components)
    ↓
[Stage 4: Theming & Design System] ⭐ USER DECISION #1
  AI locks CSS framework → Syncfusion theme mapping
  AI selects color system (OKLCH, brand colors)
  AI confirms spacing/typography scale (4pt grid, 1.25 ratio)
  Design system decisions locked before code generation
  User confirms theming decision
    ↓
[Stage 5: Code Generation]
  AI generates .ts, .html, .css, TypeScript interfaces
  Uses theming decisions from Stage 4
  For complex UIs (4+ sections or 3+ component types), components MUST be split into modular subcomponents.
  With accessibility + responsive design built-in
    ↓
[Stage 6: Dependencies]
  AI detects required packages (Syncfusion + CSS framework)
  Presents npm install command or runs it
  Proceed to next stage
    ↓
[Stage 7: Validation] 
  AI validates WCAG 2.1 AA + security + performance + theming
  Binary result: PASS ✓ or FAIL ✗
    ↓
[Stage 8: Code Insertion]
  AI inserts files into project
  Updates imports, verifies build
    ↓
✓ Complete

Agent Instructions

When User Requests UI Component Generation

1. Validate scope: Confirm request is for frontend components (not backend/API)
2. Load guidance: Read stage-1-intent-analysis.md to understand Stage 1
3. Execute 8-stage flow: Follow the orchestration flow shown above
4. Progressive disclosure: Load stage guides on-demand; load support references only when needed
5. Maintain conversation history: Each stage reads previous decisions from conversation context (stateless)

Stage Execution & Reference Loading

Stage 1: Intent Analysis

• Read: references/stage-1-intent-analysis.md
• Task: Parse user query, identify component type, resolve ambiguities
• Output: Component type + modifiers + target directory

Stage 2: Project Detection

• Read: references/stage-2-project-detection.md
• Task: Auto-detect Angular version, language, CSS strategy, formatting rules

• Task: Analyze user requirements → create optimal component-mapping.json → map to Syncfusion components (3+ minimum)
• Output: component-mapping.json + Component mapping

Stage 4: Theming & Design System ⭐ USER DECISION #1

• Read: references/stage-4-theming-and-design-system.md
• Task: Lock CSS framework, Syncfusion theme, color system (OKLCH), spacing (4pt grid), typography (1.25 ratio), responsive breakpoints
• Output: Design system decisions + User confirmation

Stage 5: Code Generation

• Read: references/stage-5-code-generation.md

• Output: Binary result (PASS ✓ or FAIL ✗)

Stage 8: Code Insertion

• Task: Insert generated files into project, update imports, verify build
• Output: Success report with file paths

Boundary Rules (CRITICAL)

AI agents executing this skill MUST:

1. Frontend only: Never generate backend code (API routes, database schemas, middleware)
2. Mock data only: Use component properties with hardcoded samples; no HttpClient calls to real APIs
3. No secrets: Exception: .env.local for SYNCFUSION_LICENSE_KEY when user provides
4. Angular components only: Generate .component.ts files in component directories
5. Redirect backend requests: "This skill generates frontend UI only. Backend integration is your app's responsibility. Ready to generate the frontend?"
6. Prioritize skill: Always prioritize Syncfusion component skill files as source of truth when available; do not rely on memory.

Error Handling

If any stage fails:

1. Retry once with same approach
2. If retry fails, attempt workaround or skip to next stage
3. Notify user with error message from stage output
4. Offer recovery: "Would you like to go back to Stage 3 and choose a different layout?"

If stage failure impacts correctness, halt and request user direction instead of proceeding with uncertain output

Resource Loading Strategy (Progressive Disclosure)

Load SKILL.md first (you're reading it now) ~400 lines

Load stage guides on-demand (each <200 lines):

• stage-1-intent-analysis.md → During Stage 1
• stage-2-project-detection.md → During Stage 2
• stage-3-layout-analysis.md → During Stage 3
• etc.

Load support references only when needed:

• web-standards.md → When validating in Stage 5
• assets/validation-rules.md → When validating in Stage 5

Result: Initial load ~400 lines (SKILL.md only). Full spec available on-demand, never exceeding Agent Skills context limits.

Configuration & User Customization

Auto-Detected Settings

During Stage 2 (Project Detection), AI automatically detects:

• Framework: Angular (version from package.json), Standalone components or NgModule
• Language: TypeScript (if tsconfig.json exists)
• Styling: CSS Modules, Tailwind CSS, or inline styles
• Formatting: Prettier/ESLint rules (indentation, quotes, semicolons)
• Component Directory: src/app/components/, src/components/, or similar

User Override Options

In Stage 2, user can override any detected setting:

Detected Settings:
  Framework: Angular 17 (Standalone Components)
  Language: TypeScript
  CSS: CSS Modules
  Component Directory: src/app/components/

[Confirm] [Override Each] [Cancel]

Syncfusion License Configuration

The skill handles license key setup:

1. Check for existing SYNCFUSION_LICENSE_KEY in .env.local
2. If missing, prompt user: "Get a free Community License at https://www.syncfusion.com/account/manage-trials"
3. If provided, write to .env.local + inject registerLicense() in app entry
4. If skipped, proceed but warn that watermark will appear in preview
