**Outcome**: All technology decisions validated and documented.
---
### ✅ Data Model (`data-model.md`)
Documented component models and design tokens:
- **Design Tokens**: Color, typography, spacing, border radius, shadows
- **10 Base Components**: Button, Card, Input, Table, Dialog, Skeleton, Alert, Badge, Select, Tooltip
- **Page-Specific Components**: MetricsSummary, UsageChart (usage page)
- **Data Fetching Models**: Server component patterns
- **State Management Models**: Client component state patterns
- **Validation Models**: Form validation with Zod
- **Accessibility Models**: Focus trap, keyboard navigation
- **Error Models**: Error states and types
- **Performance Models**: Loading states, skeleton loaders
**Outcome**: Complete UI component architecture defined.
---
### ✅ Quickstart Guide (`quickstart.md`)
Created step-by-step installation guide:
1. Install shadcn/ui CLI (`npx shadcn@latest init`)
2. Verify Tailwind CSS configuration (CSS variables)
3. Verify CSS variables in `app/globals.css`
4. Install 10 core components (Button, Card, Input, Table, Dialog, etc.)
5. Install Recharts for usage page charts
6. Create component folders (usage, billing, api-keys, settings)
7. Verify TypeScript configuration (path aliases)
8. Test installation (create test page)
9. Install development tools (Prettier, ESLint)
10. Setup accessibility testing (Lighthouse CI, axe-core)
11. Add scripts to `package.json`
**Troubleshooting**: 4 common issues documented with solutions.
**Outcome**: Complete setup guide ready for implementation.
---
### ✅ Contracts (`contracts/`)
Created TypeScript interface files:
#### `ui-components.ts` (10+ base components)
- Button, Card, Input, Table, Dialog/Modal, Skeleton, Alert, Badge, Select, Tooltip, Form
#### `page-components.ts` (15+ page-specific components)
- **Usage Page**: MetricsSummary, UsageChart, UsageMetricCard
- **Billing Page**: BillingHistory, PaymentMethodCard
- **API Keys Page**: ApiKeyList, CreateApiKeyModal, ApiKeyCreatedDialog
- **Settings Page**: HostawayCredentialsForm, OrganizationSettingsForm
- **Layout**: DashboardNav, PageHeader, EmptyState, ErrorState, LoadingState
#### `data-types.ts` (30+ type definitions)
- **Database Entities**: Organization, OrganizationMember, HostawayCredentials, ApiKey, Subscription, UsageMetrics, AuditLog
- **View Models**: UsagePageData, BillingPageData, ApiKeysPageData, SettingsPageData
- **Form Data Types**: ApiKeyFormData, HostawayCredentialsFormData, OrganizationFormData
- **Error Types**: ApiError, ValidationError
- **Loading State Types**: LoadingState, MutationState
- **Utility Types**: PaginationMeta, PaginatedResponse, SortConfig
- **Chart Data Types**: UsageChartDataPoint, BillingChartDataPoint
- **Context Types**: UserContext, OrganizationContext, DashboardContext
- **Enums**: UserRole, SubscriptionStatus, InvoiceStatus, AuditAction
#### `README.md`
- Contract usage documentation
- Examples for all component types
- Validation guidelines
**Outcome**: Complete type-safe component contracts ready for implementation.

### ✅ Agent Context Update
Updated `CLAUDE.md` with new technologies:
- **Language**: TypeScript 5.x with Next.js 15.5.4, React 19.1.0
- **Framework**: Next.js App Router, shadcn/ui, Tailwind CSS 3.x, Radix UI primitives, Supabase client
- **Database**: Supabase PostgreSQL (existing schema - no changes needed)
**Outcome**: Agent is now aware of the new technology stack.

## Design Decisions Summary
| Decision Area | Choice | Rationale |
|---------------|--------|-----------|
| **Framework Compatibility** | Next.js 15 + React 19 | Backward compatible, no blockers |
| **Styling System** | Tailwind CSS 3.x + CSS Variables | Best integration with shadcn/ui |
| **Component Library** | shadcn/ui + Radix UI | Copy-paste, full ownership, accessible |
| **Component Architecture** | `/components/ui` + feature folders | shadcn/ui convention, scalable |
| **Chart Library** | Recharts | Smallest bundle (95kb), best TypeScript support |
| **Accessibility Testing** | Lighthouse CI + axe-core + Manual | Automated + manual coverage |
| **Type Safety** | TypeScript strict mode, no `any` | Enforces type safety |

## Constitution Compliance
**Status**: ✅ **COMPLIANT WITH EXCEPTIONS**
This feature is **frontend-only** and does not introduce new API endpoints, MCP tools, or backend services. The constitution primarily governs backend development.
**Applicable Principles**:
- ✅ **Type Safety**: TypeScript strict mode, all components strongly typed
- ✅ **Test-Driven Development**: Component tests, accessibility tests
**Non-Applicable Principles**:
- ⚪ **API-First Design**: No API changes (frontend only)
- ⚪ **Security by Default**: Covered by existing Supabase Auth
- ⚪ **Async Performance**: Server Components used where possible

## Next Steps
Phase 1 is complete. Ready to proceed to **Phase 2: Task Generation**.
### Command to Continue:
```bash
/speckit.tasks
```
This will:
1. Analyze the specification, plan, and contracts
2. Generate a dependency-ordered task list (`tasks.md`)
3. Break down implementation into concrete, actionable tasks
4. Assign priorities and dependencies
5. Create a build sequence
### Expected Phase 2 Outputs:
- `tasks.md` - Actionable task list with dependencies
- Clear implementation sequence (P1 → P2 → P3)
- Estimated time per task
- Test requirements per task
