Bidirectional Agent

Register as a named agent so the phone user can send you instructions:

from lui import LuiBridge

def handle_instruction(instruction):
    """Called when user says 'tell my-bot to ...' on the phone."""
    print(f"Got: {instruction}")
    # Process the instruction with your agent logic
    return "Done!"

def handle_event(event_type, data):
    """Called for phone events (notifications, calls, 2FA codes)."""
    if event_type == "notification_2fa":
        print(f"2FA code: {data['code']}")
    elif event_type == "notification":
        print(f"Notification: {data['title']}")

bridge = LuiBridge(
    url="ws://PHONE_IP:8765",
    token="YOUR_TOKEN",
    agent_name="my-bot",
    on_instruction=handle_instruction,
    on_event=handle_event
)

bridge.connect()
print("Listening...")

# On the phone, user can say:
#   "patch me to my-bot"  → enters direct chat mode
#   "@my-bot deploy"      → sends one-off instruction
#   "tell my-bot to run tests" → LLM forwards instruction

while bridge.connected:
    time.sleep(1)

Relay Server

For access beyond the local network:

# Start relay
lui relay start --port 9000

# Phone connects to relay (configure in LUI Connection Hub)
# Agent connects via relay
lui bridge connect --url wss://RELAY_HOST/agent --token TOKEN --agent my-bot

Requirements

• Python 3.9+
• A phone running LUI with the BYOS bridge enabled
• Phone and agent on the same Wi-Fi (or use relay for remote)
