Using Agents via Claude Code Task Tool

Recommended Method: Use Claude Code's Task tool for spawning agents.

Single Agent Execution

Task("Generate tests", "Create comprehensive test suite for UserService", "qe-test-generator")

Parallel Agent Execution

// Execute multiple agents concurrently
Task("Test Generation", "Generate unit tests", "qe-test-generator")
Task("Coverage Analysis", "Analyze current coverage", "qe-coverage-analyzer")
Task("Security Scan", "Run security checks", "qe-security-scanner")
Task("Performance Test", "Load test critical paths", "qe-performance-tester")

Agent Coordination Example

// Step 1: Test generator stores results
Task("Generate tests", "Create tests and store in memory at aqe/test-plan/generated", "qe-test-generator")

// Step 2: Test executor reads from memory
Task("Execute tests", "Read test plan from aqe/test-plan/generated and execute", "qe-test-executor")

// Step 3: Coverage analyzer processes results
Task("Analyze coverage", "Check coverage from aqe/coverage/results", "qe-coverage-analyzer")

---

Using MCP Tools

Check MCP Connection

claude mcp list
# Should show: agentic-qe: npm run mcp:start - ✓ Connected

Using MCP Tools in Claude Code

// Test generation
mcp__agentic_qe__test_generate({ type: "unit", framework: "jest" })

// Test execution
mcp__agentic_qe__test_execute({ parallel: true, coverage: true })

// Quality analysis
mcp__agentic_qe__quality_analyze({ scope: "full" })

---

Agent Coordination

All agents coordinate through AQE hooks (zero external dependencies, 100-500x faster than shell hooks).

Automatic Lifecycle Hooks

Agents extend BaseAgent and override lifecycle methods:

protected async onPreTask(data: { assignment: TaskAssignment }): Promise<void> {
  // Load context before task execution
  const context = await this.memoryStore.retrieve('aqe/context', {
    partition: 'coordination'
  });

  this.logger.info('Pre-task hook complete');
}

protected async onPostTask(data: { assignment: TaskAssignment; result: any }): Promise<void> {
  // Store results after task completion
  await this.memoryStore.store('aqe/' + this.agentId.type + '/results', data.result, {
    partition: 'agent_results',
    ttl: 86400 // 24 hours
  });

  // Emit completion event
  this.eventBus.emit('task:completed', {
    agentId: this.agentId,
    result: data.result
  });

  this.logger.info('Post-task hook complete');
}

protected async onTaskError(data: { assignment: TaskAssignment; error: Error }): Promise<void> {
  // Handle task errors
  await this.memoryStore.store('aqe/errors/' + data.assignment.id, {
    error: data.error.message,
    stack: data.error.stack,
    timestamp: Date.now()
  }, {
    partition: 'errors',
    ttl: 604800 // 7 days
  });

  this.logger.error('Task failed', { error: data.error });
}

Performance Comparison

Feature	AQE Hooks	External Hooks
Speed	<1ms	100-500ms
Dependencies	Zero	External package
Type Safety	Full TypeScript	Shell strings
Integration	Direct API	Shell commands
Performance	100-500x faster	Baseline

---

Memory Namespace

Agents share state through the aqe/* memory namespace:

• aqe/test-plan/* - Test planning and requirements
• aqe/coverage/* - Coverage analysis and gaps
• aqe/quality/* - Quality metrics and gates
• aqe/performance/* - Performance test results
• aqe/security/* - Security scan findings
• aqe/swarm/coordination - Cross-agent coordination

---

Fleet Configuration

Configuration is stored in .agentic-qe/config/fleet.json:

{
  "topology": "hierarchical",
  "maxAgents": 10,
  "testingFocus": ["unit", "integration"],
  "environments": ["development"],
  "frameworks": ["jest"]
}

Topology Options

• hierarchical - Queen-led coordination with specialized workers
• mesh - Peer-to-peer with distributed decision making
• ring - Circular coordination pattern
• star - Centralized hub-and-spoke

---

Multi-Model Router

Status: Disabled by default (opt-in)

Provides 70-81% cost savings by intelligently selecting AI models based on task complexity.

Enabling Routing

Option 1: Via Configuration

// .agentic-qe/config/routing.json
{
  "multiModelRouter": {
    "enabled": true
  }
}

Option 2: Via Environment Variable

export AQE_ROUTING_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

Monitoring Costs

# View cost dashboard
aqe routing dashboard

# Export cost report
aqe routing report --format json

# Check savings
aqe routing stats

---

Streaming Progress

Status: Enabled by default

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

Example Usage

// 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 soon)
• ⚠️ Security scanning (coming soon)

# View learned patterns
aqe learn history --agent test-gen --limit 50

# Export learning data
aqe learn export --agent test-gen --output learning.json

Pattern Management

# List test patterns
aqe patterns list --framework jest

# Search patterns
aqe patterns search "api validation"

# Extract patterns from tests
aqe patterns extract ./tests --framework jest

Improvement Loop

# Start continuous improvement
aqe improve start

# Check improvement status
aqe improve status

# Run single improvement cycle
aqe improve cycle

Best Practices

1. Use Task Tool: Claude Code's Task tool is the primary way to spawn agents
2. Batch Operations: Always spawn multiple related agents in a single message
3. Memory Keys: Use the aqe/* namespace for agent coordination
4. AQE Hooks: Agents automatically use native AQE hooks for coordination (100-500x faster)
5. Parallel Execution: Leverage concurrent agent execution for speed

---

Troubleshooting

Check MCP Connection

claude mcp list
# Should show: agentic-qe: npm run mcp:start - ✓ Connected

View Agent Definitions

ls -la .claude/agents/
# Should show 18 agent markdown files

Check Fleet Status

aqe status --verbose

View Logs

tail -f .agentic-qe/logs/fleet.log

Verify Databases

# Check database files exist
ls -la .agentic-qe/db/

# Query database
node -e "const db = require('better-sqlite3')('.agentic-qe/db/memory.db'); console.log('Tables:', db.prepare('SELECT name FROM sqlite_master WHERE type=\"table\"').all()); db.close();"

// 4. Run quality gate
Task("Quality check", "Validate against quality thresholds", "qe-quality-gate")

Security and Performance Validation

Task("Performance test", "Load test with 1000 users", "qe-performance-tester")
Task("API contract check", "Validate API contracts", "qe-api-contract-validator")

Flaky Test Detection and Stabilization

Task("Hunt flaky tests", "Detect and stabilize flaky tests with ML", "qe-flaky-test-hunter")
