🏃 Quick Start

Basic Usage (Direct Session)

import asyncio
from lionagi import iModel, Session
from lionagi_qe import QETask
from lionagi_qe.agents import TestGeneratorAgent

async def main():
    # Create model and session
    model = iModel(provider="openai", model="gpt-4o-mini")
    session = Session()

    # Create agent
    agent = TestGeneratorAgent("test-gen", model)

    # Create and execute task
    task = QETask(
        task_type="generate_tests",
        context={
            "code": "def add(a, b): return a + b",
            "framework": "pytest"
        }
    )

    result = await agent.execute(task)
    print(result.test_code)

asyncio.run(main())

Using QEOrchestrator (Advanced)

from lionagi_qe import QEOrchestrator

async def orchestrated_workflow():
    # Initialize orchestrator with persistence
    orchestrator = QEOrchestrator(
        memory_backend="postgres",  # or "redis" or "memory"
        enable_learning=True
    )
    await orchestrator.initialize()

    # Execute workflow
    result = await orchestrator.execute_agent("test-generator", task)
    print(result)

Multi-Agent Pipeline

async def quality_pipeline():
    orchestrator = QEOrchestrator()
    await orchestrator.initialize()

    # Execute sequential pipeline
    result = await orchestrator.execute_pipeline(
        pipeline=[
            "test-generator",
            "test-executor",
            "coverage-analyzer",
            "quality-gate"
        ],
        context={
            "code_path": "./src",
            "coverage_threshold": 80
        }
    )

    print(f"Coverage: {result['coverage']}%")
    print(f"Quality Gate: {result['passed']}")

Parallel Agent Execution

async def parallel_analysis():
    orchestrator = QEOrchestrator()
    await orchestrator.initialize()

    # Run multiple agents in parallel
    results = await orchestrator.execute_parallel(
        agents=["test-generator", "security-scanner", "performance-tester"],
        tasks=[
            {"task": "generate_tests", "code": code1},
            {"task": "security_scan", "path": "./src"},
            {"task": "load_test", "endpoint": "/api/users"}
        ]
    )

    for agent_id, result in zip(agents, results):
        print(f"{agent_id}: {result}")

📋 Agent Coordination & Persistence

Memory Backends

Agents coordinate through a shared memory namespace (aqe/*) with multiple backend options:

Development (In-Memory):

orchestrator = QEOrchestrator(memory_backend="memory")

Production (PostgreSQL):

orchestrator = QEOrchestrator(
    memory_backend="postgres",
    postgres_url="postgresql://user:pass@localhost:5432/lionagi_qe"
)

Production (Redis):

orchestrator = QEOrchestrator(
    memory_backend="redis",
    redis_url="redis://localhost:6379/0"
)

Memory Namespace

aqe/
├── test-plan/      # Test requirements and plans
├── coverage/       # Coverage analysis results
├── quality/        # Quality metrics and gates
├── performance/    # Performance test results
├── security/       # Security scan findings
├── patterns/       # Learned test patterns
└── swarm/         # Multi-agent coordination

Setup Persistence

PostgreSQL (Recommended for production):

# Using Docker
docker run -d \
  -e POSTGRES_DB=lionagi_qe \
  -e POSTGRES_USER=qe_user \
  -e POSTGRES_PASSWORD=secure_password \
  -p 5432:5432 \
  postgres:16-alpine

# Initialize schema
python -m lionagi_qe.persistence.init_db

Redis (Fast, ephemeral):

docker run -d -p 6379:6379 redis:7-alpine

💡 Advanced Features

Multi-Model Routing

Automatically route tasks to optimal models for cost efficiency:

orchestrator = QEOrchestrator(enable_routing=True)

# Simple tasks → GPT-3.5 ($0.0004)
# Moderate tasks → GPT-4o-mini ($0.0008)
# Complex tasks → GPT-4 ($0.0048)
# Critical tasks → Claude Sonnet 4.5 ($0.0065)

Q-Learning Integration

Agents learn from past executions with persistent storage:

# Enable learning with PostgreSQL backend
orchestrator = QEOrchestrator(
    enable_learning=True,
    memory_backend="postgres"
)

# Agents automatically improve through experience
# Target: 20% improvement over baseline
# Learning data persists across restarts

Custom Workflows with LionAGI Builder

Build complex workflows directly with LionAGI's Builder pattern:

from lionagi import Builder, Session

# Direct LionAGI usage (no wrapper)
session = Session()
builder = Builder("CustomQEWorkflow")

node1 = builder.add_operation("test-generator", context=ctx)
node2 = builder.add_operation("security-scanner", depends_on=[node1])
node3 = builder.add_operation("quality-gate", depends_on=[node1, node2])

result = await session.flow(builder.get_graph())

Or use QEOrchestrator for convenience:

from lionagi_qe import QEOrchestrator

orchestrator = QEOrchestrator()
result = await orchestrator.execute_workflow(builder.get_graph())
