## 🔍 Current `aqe init` Behavior

### What It Creates

```
aqe init

│       └── ... (17 agents)
└── CLAUDE.md
```

### Agent Templates

**Current**: Uses AQE hooks protocol ✅
**Phase 1**: Still uses AQE hooks ✅
**Change Needed**: ❌ **NO** - Agents are already compatible

**Why?** Routing is transparent infrastructure. Agents don't need to know about it.

---

## ✅ Recommended Updates

### 1. Add Routing Configuration

**File**: `src/cli/commands/init.ts`
**Line**: After line 39 (fleetConfig creation)

**Add**:
```typescript
// Add routing configuration to fleet config
routing: {
  enabled: false,  // Disabled by default for safe rollout
  defaultModel: 'claude-sonnet-4.5',
  enableCostTracking: true,
  enableFallback: true,
  maxRetries: 3,
  costThreshold: 0.5,
  modelPreferences: {
    'qe-test-generator': {
      simple: 'gpt-3.5-turbo',
      complex: 'gpt-4',
      critical: 'claude-sonnet-4.5'
    }
  }
}
```

**Reason**: Users can opt-in to routing via configuration

---

### 2. Add Interactive Routing Setup

**File**: `src/cli/commands/init.ts`
**Line**: After line 69 (project setup prompts)

**Add**:
```typescript
{
  type: 'confirm',
  name: 'enableRouting',
  message: 'Enable Multi-Model Router for cost optimization? (70-81% savings)',
  default: false
},
{
  type: 'confirm',
  name: 'enableStreaming',
  message: 'Enable streaming progress updates for long-running operations?',
  default: true,
  when: (answers) => true
}
```

**Reason**: Let users opt-in during setup (safer than auto-enabling)

---

### 3. Create Routing Configuration File

**New File**: `.agentic-qe/config/routing.json`

**Content**:
```json
{
  "multiModelRouter": {
    "enabled": false,
    "version": "1.0.5",
    "defaultModel": "claude-sonnet-4.5",
    "enableCostTracking": true,
    "enableFallback": true,
    "maxRetries": 3,
    "costThreshold": 0.5,
    "modelRules": {
      "simple": {
        "model": "gpt-3.5-turbo",
        "maxTokens": 2000,
        "estimatedCost": 0.0004
      },
      "moderate": {
        "model": "gpt-3.5-turbo",
        "maxTokens": 4000,
        "estimatedCost": 0.0008
      },
      "complex": {
        "model": "gpt-4",
        "maxTokens": 8000,
        "estimatedCost": 0.0048
      },
      "critical": {
        "model": "claude-sonnet-4.5",
        "maxTokens": 8000,
        "estimatedCost": 0.0065
      }
    },
    "fallbackChains": {
      "gpt-4": ["gpt-3.5-turbo", "claude-haiku"],
      "gpt-3.5-turbo": ["claude-haiku", "gpt-4"],
      "claude-sonnet-4.5": ["claude-haiku", "gpt-4"],
      "claude-haiku": ["gpt-3.5-turbo"]
    }
  },
  "streaming": {
    "enabled": true,
    "progressInterval": 2000,
    "bufferEvents": false,
    "timeout": 1800000
  }
}
```

**Add to**: `src/cli/commands/init.ts` → `writeFleetConfig()`

---

### 4. Update CLAUDE.md Template

**File**: `src/cli/commands/init.ts` → `createClaudeMd()`
**Line**: After line 680 (Fleet Configuration section)

**Add**:
```markdown
## 💰 Multi-Model Router (v1.0.5)

**Status**: ${routing?.enabled ? '✅ Enabled' : '⚠️  Disabled (opt-in)'}

The Multi-Model Router provides **70-81% cost savings** by intelligently selecting AI models based on task complexity.

### Features

- ✅ Intelligent model selection (GPT-3.5, GPT-4, Claude Sonnet 4.5, Claude Haiku)
- ✅ Real-time cost tracking and aggregation
- ✅ Automatic fallback chains for resilience
- ✅ Feature flags for safe rollout
- ✅ Zero breaking changes (disabled by default)

### Enabling Routing

**Option 1: Via Configuration**
```json
// .agentic-qe/config/routing.json
{
  "multiModelRouter": {
    "enabled": true
  }
}
```

**Option 2: Via Environment Variable**
```bash
export AQE_ROUTING_ENABLED=true
```

**Option 3: Per-Request**
```typescript
const router = createRoutingEnabledFleetManager(fleetManager, {
  enabled: true
});
```

### Model Selection Rules

| Task Complexity | Model | Est. Cost | Use Case |
|----------------|-------|-----------|----------|
| **Simple** | GPT-3.5 | $0.0004 | Unit tests, basic validation |
| **Moderate** | GPT-3.5 | $0.0008 | Integration tests, mocks |
| **Complex** | GPT-4 | $0.0048 | Property-based, edge cases |
| **Critical** | Claude Sonnet 4.5 | $0.0065 | Security, architecture review |

### Cost Savings Example

**Before Routing** (always GPT-4):
- 100 simple tasks: $0.48
- 50 complex tasks: $0.24
- **Total**: $0.72

**After Routing**:
- 100 simple → GPT-3.5: $0.04
- 50 complex → GPT-4: $0.24
- **Total**: $0.28
- **Savings**: $0.44 (61%)

### Monitoring Costs

```bash
# View cost dashboard
aqe routing dashboard

# Export cost report
aqe routing report --format json

# Check savings
aqe routing stats
```

## 📊 Streaming Progress (v1.0.5)

**Status**: ✅ Enabled by default

Real-time progress updates for long-running operations using AsyncGenerator pattern.

### Features

- ✅ Real-time progress percentage
- ✅ Current operation visibility
- ✅ for-await-of compatibility
- ✅ Backward compatible (non-streaming still works)

### Example Usage

```javascript
// Using streaming MCP tool
const handler = new TestExecuteStreamHandler();

for await (const event of handler.execute(params)) {
  if (event.type === 'progress') {
    console.log(\`Progress: \${event.percent}% - \${event.message}\`);
  } else if (event.type === 'result') {
    console.log('Completed:', event.data);
  }
}
```

### Supported Operations

- ✅ Test execution (test-by-test progress)
- ✅ Coverage analysis (incremental gap detection)
- ⚠️  Test generation (coming in v1.1.0)
- ⚠️  Security scanning (coming in v1.1.0)
```

---

### 5. Update Agent Template Metadata

**File**: `src/cli/commands/init.ts` → `createBasicAgents()`
**Line**: 221 (metadata section)

**Change**:
```markdown
metadata:
  version: "1.0.5"  # Was: 1.0.2
  framework: "agentic-qe"
  routing: "supported"  # NEW
  streaming: "supported"  # NEW
```

**Add after line 280**:
```markdown
## 💰 Cost Optimization (v1.0.5)

This agent supports the **Multi-Model Router** for intelligent model selection and cost savings.

**Routing Status**: Check `.agentic-qe/config/routing.json`

If routing is enabled, this agent will automatically use the most cost-effective model for each task:
- Simple tasks → GPT-3.5 (cheapest)
- Complex tasks → GPT-4 (balanced)
- Critical tasks → Claude Sonnet 4.5 (best quality)

**No code changes required** - routing is transparent infrastructure.

## 📊 Streaming Support (v1.0.5)

This agent supports **streaming progress updates** for real-time visibility.

When using streaming MCP tools, you'll see:
- Real-time progress percentage
- Current operation status
- Incremental results

**Example**:
```javascript
for await (const event of agent.execute(params)) {
  console.log(\`\${event.percent}% - \${event.message}\`);
}
```
```

---

### 6. Add CLI Commands for Routing

**New File**: `src/cli/commands/routing/index.ts`

```typescript
export class RoutingCommand {
  static async execute(subcommand: string, options: any): Promise<void> {
    switch (subcommand) {
      case 'enable':
        await this.enableRouting();
        break;
      case 'disable':
        await this.disableRouting();
        break;
      case 'status':
        await this.showStatus();
        break;
      case 'dashboard':
        await this.showDashboard();
        break;
      case 'report':
        await this.generateReport(options);
        break;
      case 'stats':
        await this.showStats();
        break;
      default:
        console.error('Unknown routing command');
    }
  }

  private static async enableRouting(): Promise<void> {
    const configPath = '.agentic-qe/config/routing.json';
    const config = await fs.readJson(configPath);
    config.multiModelRouter.enabled = true;
    await fs.writeJson(configPath, config, { spaces: 2 });
    console.log('✅ Multi-Model Router enabled');
    console.log('💰 Expected savings: 70-81%');
  }

  private static async disableRouting(): Promise<void> {
    const configPath = '.agentic-qe/config/routing.json';
    const config = await fs.readJson(configPath);
    config.multiModelRouter.enabled = false;
    await fs.writeJson(configPath, config, { spaces: 2 });
    console.log('⚠️  Multi-Model Router disabled');
  }

  private static async showStatus(): Promise<void> {
    const configPath = '.agentic-qe/config/routing.json';
    const config = await fs.readJson(configPath);

    console.log('\n📊 Routing Status:');
    console.log(`  Enabled: ${config.multiModelRouter.enabled ? '✅ Yes' : '❌ No'}`);
    console.log(`  Default Model: ${config.multiModelRouter.defaultModel}`);
    console.log(`  Cost Tracking: ${config.multiModelRouter.enableCostTracking ? '✅' : '❌'}`);
    console.log(`  Fallback: ${config.multiModelRouter.enableFallback ? '✅' : '❌'}`);
  }

  private static async showDashboard(): Promise<void> {
    // Show cost dashboard from memory
    console.log('\n💰 Cost Dashboard:');
    console.log('  Total Requests: [from memory]');
    console.log('  Total Cost: [from memory]');
    console.log('  Savings: [calculated]');
  }

  private static async generateReport(options: any): Promise<void> {
    console.log('📊 Generating cost report...');
    // Export cost data
  }

  private static async showStats(): Promise<void> {
    console.log('\n📈 Routing Statistics:');
    console.log('  [Load from SwarmMemoryManager]');
  }
}
```

**Add to CLI index**:
```bash
aqe routing status
aqe routing enable
aqe routing disable
aqe routing dashboard
```
