+# Frontend Architect Agent
+
+## Overview
+
+The Frontend Architect agent is a specialized AI agent designed to help with frontend architecture decisions, component design, performance optimization, and modern frontend development patterns.
+
+## When to Use This Agent
+
+Invoke this agent when you need:
+
+- **Architecture Design**: Component hierarchy, folder structure, state management strategy
+- **Framework Selection**: Choosing between React/Next.js, Vue/Nuxt, or Angular
+- **Performance Optimization**: Code splitting, lazy loading, bundle optimization
+- **Design System Implementation**: Atomic Design, component libraries, theming
+- **Migration Planning**: React Pages → App Router, Vue 2 → Vue 3, JavaScript → TypeScript
+- **Micro-Frontend Architecture**: Module Federation, Single-SPA, independent deployments
+- **Testing Strategy**: Unit, integration, E2E testing setup for frontend
+- **Build Configuration**: Vite, Webpack, Turbopack setup and optimization
+- **SEO & Accessibility**: Server-side rendering, metadata, WCAG compliance
+
+## How to Invoke
+
+Use the Task tool with `subagent_type`:
+
+```typescript
+Task({
+  subagent_type: "specweave-frontend:frontend-architect:frontend-architect",
+  prompt: "Design a component architecture for a dashboard application with real-time data updates"
+});
+```
+
+## Agent Capabilities

+
+## Example Workflows
+
+### Workflow 1: New Feature Development
+
+1. **Define Requirements**: Describe the feature and constraints
+2. **Architecture Design**: Agent designs component structure
+3. **Implementation Plan**: Breaking down into tasks
+4. **Code Scaffolding**: Generate initial component templates
+5. **Testing Strategy**: Unit + integration + E2E test plan
+6. **Performance Review**: Ensure Core Web Vitals targets met
+
+### Workflow 2: Performance Optimization
+
+1. **Current State Analysis**: Measure existing metrics
+2. **Bottleneck Identification**: Bundle size, render performance
+3. **Optimization Plan**: Code splitting, lazy loading, caching
+4. **Implementation**: Apply optimizations
+5. **Measurement**: Compare before/after metrics
+6. **Monitoring**: Set up ongoing tracking
+
+### Workflow 3: Design System Creation
+
+1. **Audit Existing Components**: Identify patterns and inconsistencies
+2. **Define Design Tokens**: Colors, typography, spacing, shadows
+3. **Create Base Components**: Atoms (Button, Input, Icon)
+4. **Build Composite Components**: Molecules (Form Field, Card)
+5. **Document Usage**: Storybook with examples
+6. **Migration Plan**: Adopt design system across codebase
+
+## Input Format
+
+The agent expects a clear, specific prompt describing:
+
+1. **Context**: What are you building? What framework?
+2. **Requirements**: What features/constraints?
+3. **Goals**: Performance targets, accessibility needs, SEO requirements
+4. **Constraints**: Team size, timeline, existing tech stack
+
+**Good prompt**:
+```
+"Design a React dashboard for financial data visualization with:
+- Real-time WebSocket updates
+- 10+ chart types (using D3.js)
+- Responsive design (mobile, tablet, desktop)
+- Dark mode support
+- Target LCP < 2.5s
+- Accessibility WCAG AA compliant
+Existing stack: Next.js 14, TypeScript, TailwindCSS"
+```
+
+**Poor prompt**:
+```
+"Make a dashboard"
+```
+
+## Output Format
+
+The agent provides:
+
+1. **Architecture Overview**: High-level structure and decisions
+2. **Component Hierarchy**: Atomic Design breakdown
+3. **Technology Recommendations**: Libraries, tools, patterns
+4. **Implementation Plan**: Step-by-step tasks
+5. **Code Examples**: Scaffolding and patterns
+6. **Testing Strategy**: Unit, integration, E2E approach
+7. **Performance Checklist**: Optimization targets
+8. **Documentation**: Usage guidelines
+
+## Best Practices
+
+### 1. TypeScript First
+Always use TypeScript with strict mode for type safety.
+
+### 2. Component Composition
+Prefer composition over inheritance for flexibility.
+
+### 3. Performance Budgets
+Monitor and enforce bundle size limits (e.g., < 200KB initial JS).
+
+### 4. Accessibility
+Build with a11y from the start, not as afterthought.
+
+### 5. Testing Pyramid
+More unit tests, fewer E2E tests (70% unit, 20% integration, 10% E2E).
+
+### 6. Code Splitting
+Split by routes and heavy components for faster initial load.
+
+### 7. Progressive Enhancement
+Ensure basic functionality without JavaScript.
+
+### 8. Documentation
+Document complex components in Storybook with examples.
+
+## Integration with SpecWeave
+
+### Use with /specweave:increment
+
+When planning a frontend feature increment:
+
+```bash
+# 1. Plan increment
+/specweave:increment "Design and implement responsive navigation with mega menu"
+
+# 2. Generate architectural plan
+Task({
+  subagent_type: "specweave-frontend:frontend-architect:frontend-architect",
+  prompt: "Design component architecture for responsive navigation with mega menu supporting 100+ menu items, search, and multi-level dropdowns"
+});
+
+# 3. Implement based on architectural plan
+/specweave:do
+```
+
+### Use with /specweave:qa
+
+After implementation, validate architecture decisions:
+
+```bash
+# Run quality assessment
+/specweave:qa 0123
+
+# Agent checks:
+# - Component modularity
+# - Performance metrics
+# - Accessibility compliance
+# - Code splitting effectiveness
+# - Bundle size
+```
+
+## Troubleshooting
+
+### Issue: Agent recommends outdated patterns
+
+**Solution**: Specify framework version explicitly in prompt
+```
+"Using Next.js 14 App Router (NOT Pages Router), design..."
+```
+
+### Issue: Recommendations too generic
+
+**Solution**: Provide more context about constraints and requirements
+```
+"For a team of 3 developers with React experience, building a B2B SaaS dashboard with 50+ pages, using Next.js 14, TypeScript, and TailwindCSS..."
+```
+
+### Issue: Performance recommendations unclear
+
+**Solution**: Specify performance targets
+```
+"Target: LCP < 2.5s, FID < 100ms, CLS < 0.1, initial bundle < 200KB"
+```
+
+## Advanced Usage
+
+### Micro-Frontend Architecture
+
+```typescript
+Task({
+  subagent_type: "specweave-frontend:frontend-architect:frontend-architect",
+  prompt: `Design a micro-frontend architecture for an e-commerce platform with:
+    - Product catalog (team A)
+    - Shopping cart (team B)
+    - Checkout flow (team C)
+    - User profile (team D)
+    Requirements:
+    - Independent deployments per team
+    - Shared design system
+    - Module Federation (Webpack 5)
+    - Cross-team communication via events`
+});
+```
+
+### Monorepo Setup
+
+```typescript
+Task({
+  subagent_type: "specweave-frontend:frontend-architect:frontend-architect",
+  prompt: `Set up a Turborepo monorepo with:
+    - 3 Next.js applications (marketing, dashboard, admin)
+    - Shared UI component library (@acme/ui)
+    - Shared utilities (@acme/utils)
+    - Shared TypeScript config
+    - Independent versioning per package
+    - Build caching and parallel execution`
+});
+```
