    # Register a protocol
    Agentic.Protocol.Registry.register(:claude_code, Agentic.Protocol.ClaudeCode)

    # Look up a protocol
    {:ok, module} = Agentic.Protocol.Registry.lookup(:claude_code)

    # List all protocols
    Agentic.Protocol.Registry.list()

    # Get protocols by transport type
    Agentic.Protocol.Registry.for_transport(:local_agent)
