## Auto-Detected Backend Services

Morphkit scans package.json and source files to auto-detect:

| Web Service | npm Package | iOS Output |
|-------------|------------|------------|
| Supabase | @supabase/supabase-js | SupabaseManager.swift (auth, db, storage, realtime) |
| Stripe | stripe | PaymentManager.swift + CheckoutView.swift |
| SSE Streaming | (detected in API routes) | SSEClient.swift (AsyncThrowingStream) |
| Markdown | react-markdown | MarkdownUI package dependency |
| Firebase | firebase | Detected (generation planned) |
| Clerk | @clerk/nextjs | Detected (generation planned) |

Package.swift automatically includes Supabase Swift SDK and MarkdownUI when detected.

## Example Workflows

### Convert a Next.js app to iOS (CLI)

```bash
# Step 1: See what Morphkit will build
npx morphkit-cli plan ./my-saas-app
# Output: Detected Stack (Supabase, Stripe), 14 recommended screens, 8 excluded

# Step 2: Generate the iOS project
npx morphkit-cli generate ./my-saas-app -o ./ios-app -n MySaas
# Output: 45 Swift files generated, zero build errors

# Step 3: Auto-complete remaining TODOs
ANTHROPIC_API_KEY=sk-ant-... npx morphkit-cli complete ./ios-app --verbose
# Output: 6 TODOs resolved, 0 remaining, build: pass

# Step 4: Open in Xcode
cd ios-app && open Package.swift
```

### Use with Claude Code (MCP)

```bash
# Register MCP server
npx morphkit-cli setup

# Then in Claude Code, ask:
# "Convert my React app at ./my-webapp to an iOS app"
# Claude Code will call morphkit_plan → morphkit_generate → morphkit_complete_screen
```

### Check project status

```bash
npx morphkit-cli verify ./ios-app
# Build:   PASS (0 errors)
# Screen:  44/47 (94%)
# API:     165/165 (100%)
# Overall: 97% complete
```

## VerifyResult Schema

```typescript
interface VerifyResult {
  buildStatus: 'pass' | 'fail' | 'skipped';
  buildErrors: number;
  todosByCategory: Record<string, number>;   // e.g. { "wire-api-fetch": 8, "wire-api-action": 4 }
  todosByFile: Record<string, number>;       // e.g. { "CartView.swift": 3, "ProductDetailView.swift": 2 }
  totalTodos: number;
  screenCompletion: { total: number; complete: number; percentage: number };
  apiCoverage: { total: number; wired: number; percentage: number };
  modelCompleteness: { total: number; complete: number; percentage: number };
  apiBaseUrlSet: boolean;
  authWired: boolean;
  overallPercentage: number;
  nextStep: string;
}
```

## MORPHKIT-TODO System

Generated Swift files contain structured TODO markers for AI-assisted completion.

### Format

```swift
// MORPHKIT-TODO: <category>
// MORPHKIT-TODO-COUNT: <n>
```

### Categories

| Category | Meaning | Where it appears |
|----------|---------|-----------------|
| `wire-api-fetch` | Connect view data loading to APIClient | View `.task {}` or `.onAppear {}` |
| `wire-api-action` | Connect user action to APIClient | Button/form action closures |
| `complete-model` | Add real fields to placeholder model | Model files with ≤1 field |
| `implement-auth` | Wire authentication flow | Auth-related views and stores |

### Completion Detection

A screen is considered complete when:
1. It has a `// MORPHKIT-TODO-COUNT: 0` line, OR
2. It has no `MORPHKIT-TODO` or `// TODO:` markers remaining

## AI Provider Configuration

Environment variables (set any one):
  - ANTHROPIC_API_KEY — Claude (recommended)
  - OPENAI_API_KEY — OpenAI GPT
  - XAI_API_KEY — xAI Grok

CLI override: `--ai-provider claude|openai|grok`
Disable AI: `--no-ai`

Auto-detection order: Claude → OpenAI → Grok → heuristics fallback.

When configured, AI enhances: intent analysis, component mapping, navigation planning, state architecture, code generation.
