run_agents(
    agent1, agent2,
    backend_config={...},
    channel_queue_map={
        "channel1": "existing.queue.1",
        "channel2": "existing.queue.2"
    }
)

Migration Path (v0.7.13 → v0.7.14)

If you were using RabbitMQ in v0.7.13:

# Old way (didn't work - agents didn't consume messages)
@agent("processor")
def process(spore):
    return {}

# New way (v0.7.14 - works correctly)
from praval.composition import run_agents

run_agents(
    process,
    backend_config={'url': 'amqp://localhost:5672/'}
)
