Configuration Changes

Automatic Migration

The migration tool automatically updates your config:

aqe migrate --to v1.0.5

# Output:
✓ Backed up config to .agentic-qe/config.yaml.backup
✓ Added multi-model router configuration
✓ Added streaming configuration
✓ Added cost tracking configuration
✓ Migration complete!

Next steps:
1. Review config: .agentic-qe/config.yaml
2. Set API keys: OPENAI_API_KEY, ANTHROPIC_API_KEY
3. Test: aqe test src/example.ts
4. Monitor: aqe cost dashboard

Manual Migration Steps

If you prefer manual migration:

Step 1: Backup existing config

cp .agentic-qe/config.yaml .agentic-qe/config.yaml.backup

Step 2: Add new sections

# Add to existing config.yaml

# New: Features section
features:
  multiModelRouter: true
  streamingTools: true
  costTracking: true

# New: Models section
models:
  available: [...]  # See full config above
  defaultModel: gpt-3.5-turbo

# New: Routing section
routing:
  strategy: adaptive
  agentOverrides: [...]

# New: Streaming section
streaming:
  enabled: true
  updateInterval: 1000

# New: Cost tracking section
costTracking:
  enabled: true
  granularity: detailed

Step 3: Validate config

aqe config validate

# Output:
✓ Config is valid
✓ All required fields present
✓ Model configurations valid
✓ API keys found

Step 4: Test

# Test multi-model router
aqe test src/utils/validator.ts

# Check which model was used
aqe cost report --last

# Test streaming
aqe test src/services/user-service.ts --stream

// New: Model router
const router = new ModelRouter();
const model = await router.selectModel(task);

// New: Cost tracker
const tracker = new CostTracker();
const costs = await tracker.getTodayCost();

Testing Your Migration

1. Smoke Tests

# Install v1.0.5
npm install -g agentic-qe@1.0.5

# Verify version
aqe --version  # Should show 1.0.5

# Run basic tests
aqe init --test-migration
aqe test examples/simple.ts
aqe status

2. Feature Tests

# Test multi-model router
aqe test src/ --verbose

# Check cost report
aqe cost report --today

# Test streaming
aqe test src/ --stream

3. Integration Tests

import { FleetManager } from 'agentic-qe';
import { expect } from 'chai';

describe('v1.0.5 Migration Tests', () => {
  let fleet: FleetManager;

  before(async () => {
    fleet = new FleetManager();
    await fleet.initialize();
  });

  it('should support multi-model router', async () => {
    const result = await fleet.generateTests({
      sourceFile: 'test-data/simple.ts',
      framework: 'jest'
    });

    expect(result.success).to.be.true;
    expect(result.metadata.modelUsed).to.exist;
    expect(result.metadata.cost).to.be.lessThan(0.10);
  });

  it('should support streaming', async () => {
    const stream = await fleet.streamTestGeneration({
      sourceFile: 'test-data/simple.ts'
    });

    let progressUpdates = 0;
    stream.on('progress', () => progressUpdates++);

    const result = await stream.complete();

    expect(result.success).to.be.true;
    expect(progressUpdates).to.be.greaterThan(0);
  });

  it('should maintain backward compatibility', async () => {
    // Old code still works
    const result = await fleet.generateTests({
      sourceFile: 'test-data/simple.ts'
    });

    expect(result.success).to.be.true;
    expect(result.testCount).to.be.greaterThan(0);
  });
});

Troubleshooting

Issue 1: Config Validation Fails

Error: Config validation failed: models.available is required

Solution:

# Run automatic migration
aqe migrate --to v1.0.5

# Or add manually
echo "models:
  available:
    - id: gpt-3.5-turbo
      provider: openai
      costPer1kTokens: 0.002
" >> .agentic-qe/config.yaml

---

Issue 2: API Keys Not Found

Error: OpenAI API key not found

Solution:

# Set API keys
export OPENAI_API_KEY="sk-..."
export ANTHROPIC_API_KEY="sk-ant-..."

# Or add to .env file
echo "OPENAI_API_KEY=sk-..." >> .env
echo "ANTHROPIC_API_KEY=sk-ant-..." >> .env

---

Issue 3: Router Not Selecting Cheaper Models

Symptoms: All tasks still use expensive models

Solution:

# Adjust complexity thresholds
routing:
  complexity:
    simple:
      maxLines: 200  # Increase
      maxComplexity: 10  # Increase

# Or force cost-optimized strategy
routing:
  strategy: cost-optimized

---

Issue 4: Streaming Not Working

Symptoms: No progress updates received

Solution:

// Attach listeners BEFORE starting stream
stream.on('progress', handler);
await stream.start();  // Not before!

// Check if streaming is enabled
console.log(config.features.streamingTools);  // Should be true

---

Rollback Plan

If you encounter issues, you can easily rollback:

Rollback to v1.0.4

# 1. Restore backup config
cp .agentic-qe/config.yaml.backup .agentic-qe/config.yaml

# 2. Downgrade package
npm install -g agentic-qe@1.0.4

# 3. Verify
aqe --version  # Should show 1.0.4

# 4. Test
aqe status
aqe test src/example.ts

Partial Rollback (Disable Features)

# Keep v1.0.5 but disable new features
features:
  multiModelRouter: false
  streamingTools: false

# Existing functionality still works!

---

Performance Comparison

Before (v1.0.4) vs After (v1.0.5)

Metric	v1.0.4	v1.0.5	Change
Cost per test	$0.15	$0.03	-80%
Test generation	45s	45s	0%
User feedback	After complete	Real-time	+∞%
Uptime	95%	99.5%	+4.7%
Memory usage	512 MB	480 MB	-6.2%

Resource Usage

# Before v1.0.5
Memory: 512 MB
Connections: 50 (new each time)
API calls: 1,000/day

# After v1.0.5
Memory: 480 MB (-6%)
Connections: 10 (pooled, reused)
API calls: 1,000/day (same)
Cost: -70% (multi-model router)

Common Migration Issues

Issue: "Feature flags not recognized"

Cause: Older config format

Fix:

aqe migrate --to v1.0.5 --force

---

Issue: "Cost tracking database error"

Cause: First time setup

Fix:

# Initialize cost tracking
aqe cost init

# This creates .agentic-qe/costs.db

---

Issue: "Model not found: gpt-3.5-turbo"

Cause: API key not configured

Fix:

export OPENAI_API_KEY="sk-..."
aqe config validate

Best Practices

1. Gradual Rollout

# Week 1: 10%
routing:
  rolloutPercentage: 0.10

# Week 2: 50%
routing:
  rolloutPercentage: 0.50

# Week 3: 100%
routing:
  rolloutPercentage: 1.0

2. Monitor Metrics

# Daily checks
aqe cost report --today
aqe router analyze --performance

# Weekly reviews
aqe cost report --week
aqe cost optimize --suggest

3. Set Budgets

costTracking:
  budgets:
    daily: 50.00
    monthly: 1000.00

4. Enable Alerts

costTracking:
  alerts:
    - type: daily
      threshold: 40.00  # 80% of budget
      action: email
