Managing Dependencies

1. Go to root folder of gllm-agents module, e.g. cd libs/gllm-agents.
2. Run poetry shell to create a virtual environment.
3. Run poetry lock to create a lock file if you haven't done it yet.
4. Run poetry install to install the gllm-agents requirements for the first time.
5. Run poetry update if you update any dependency module version at pyproject.toml.

Hello World Examples

Prerequisites

• Python 3.11+
• Install the binary package:

pip install gllm-agents-binary

• For OpenAI: Set your API key in the environment:

export OPENAI_API_KEY=your-openai-key

export GOOGLE_API_KEY=your-google-api-key

Run the Hello World Examples

The example scripts are located in the gllm_agents/examples directory within the library. You can run them individually or use the run_all_examples.py script.

1. Running Individual Examples:

Navigate to the library's root directory (e.g., libs/gllm-agents if you cloned the repository).

LangGraph (OpenAI):

python gllm_agents/examples/hello_world_langgraph.py
# or, if your PYTHONPATH is set up or the package is installed:
# python -m gllm_agents.examples.hello_world_langgraph

LangGraph Streaming (OpenAI):

python gllm_agents/examples/hello_world_langgraph_stream.py
# or, if your PYTHONPATH is set up or the package is installed:
# python -m gllm_agents.examples.hello_world_langgraph_stream

Google ADK:

python gllm_agents/examples/hello_world_google_adk.py
# or, if your PYTHONPATH is set up or the package is installed:
# python -m gllm_agents.examples.hello_world_google_adk

Google ADK Streaming:

python gllm_agents/examples/hello_world_google_adk_stream.py
# or, if your PYTHONPATH is set up or the package is installed:
# python -m gllm_agents.examples.hello_world_google_adk_stream

2. Running Individual MCP Examples:

• Navigate to the library's root directory (e.g., libs/gllm-agents if you cloned the repository).

• Open a new terminal and navigate to the sample MCP servers directory libs/gllm-agents/gllm_agents/examples/mcp_servers

  Turn on the SSE MCP servers:

  python mcp_server_sse.py
  

• Open a new terminal and navigate to the sample MCP servers directory libs/gllm-agents/gllm_agents/examples/mcp_servers

  Turn on the STDIO MCP servers:

  python mcp_server_stdio.py
  

LangGraph SSE Transport (OpenAI):

python gllm_agents/examples/hello_world_langgraph_mcp_sse.py
# or, if your PYTHONPATH is set up or the package is installed:
# python -m gllm_agents.examples.hello_world_langgraph_mcp_sse

LangGraph Streaming SSE Transport (OpenAI):

python gllm_agents/examples/hello_world_langgraph_mcp_sse_stream.py
# or, if your PYTHONPATH is set up or the package is installed:
# python -m gllm_agents.examples.hello_world_langgraph_mcp_sse_stream

LangGraph STDIO Transport (OpenAI):

python gllm_agents/examples/hello_world_langgraph_mcp_stdio.py
# or, if your PYTHONPATH is set up or the package is installed:
# python -m gllm_agents.examples.hello_world_langgraph_mcp_stdio

LangGraph Streaming STDIO Transport (OpenAI):

python gllm_agents/examples/hello_world_langgraph_mcp_stdio_stream.py
# or, if your PYTHONPATH is set up or the package is installed:
# python -m gllm_agents.examples.hello_world_langgraph_mcp_stdio_stream

Architectural Notes

Agent Interface (AgentInterface)

The gllm_agents.agent.interface.AgentInterface class defines a standardized contract for all agent implementations within the GLLM Agents ecosystem. It ensures that different agent types (e.g., LangGraph-based, Google ADK-based) expose a consistent set of methods for core operations.

Key methods defined by AgentInterface typically include:

• arun(): For asynchronous execution of the agent that returns a final consolidated response.
• arun_stream(): For asynchronous execution that streams back partial responses or events from the agent.

By adhering to this interface, users can interact with various agents in a uniform way, making it easier to switch between or combine different agent technologies.

Inversion of Control (IoC) / Dependency Injection (DI)

The agent implementations (e.g., LangGraphAgent, GoogleADKAgent) utilize Dependency Injection. For instance, LangGraphAgent accepts an agent_executor (like one created by LangGraph's create_react_agent) in its constructor. Similarly, GoogleADKAgent accepts a native adk_native_agent. This allows the core execution logic to be provided externally, promoting flexibility and decoupling the agent wrapper from the specific instantiation details of its underlying engine.
