# gpt_agents.py

> **Unique:** This is a single-file, multi-agent framework for LLMs—everything is implemented in one core file with no dependencies for maximum clarity and hackability. See the main implementation here: [`gpt_agents.py`](gpt_agents_py/gpt_agents.py)

A minimal, modular Python framework for building and running multi-agent LLM workflows with tool use, validation, and orchestration. 

## Project Overview

gpt_agents.py provides abstractions for:
- **Agent**: An LLM-powered entity with a goal, backstory, tasks, and tools.
- **Task**: A unit of work for an agent, with a description and expected output.
- **Tool**: A callable function the agent can use, with a name, description, and argument schema.
- **Organization**: A group of agents working together, passing results between them.

The framework manages LLM prompting, tool execution, validation, and robust control flow to maximize correct answers. See [`tests/test_integration.py`](tests/test_integration.py) for advanced usage and testing patterns.

## Requirements
- Python 3.11+ (standard library only)
- [OpenAI API Key](https://platform.openai.com/account/api-keys) in `api_key.json` at the project root:
  ```json
  { "openai": "sk-..." }
  ```

## Installation

```bash
git clone <repository-url>
cd gpt_agents.py
```

No pip or poetry installation required for runtime. This project has **zero runtime dependencies** and uses only the Python standard library.

For development (linting, formatting, type checking, testing), install dev dependencies:
```bash
pip install black isort mypy flake8
```
Or, if using Poetry:
```bash
poetry install --with dev
```
## Usage

### Running the example

Runnable demos are located in the `examples/` directory. To run the basic usage example:

```bash
python examples/basic_usage.py                               # Normal mode
python examples/basic_usage.py --debug                       # Step-through debug mode for agent reasoning
python examples/basic_usage.py --trace                       # Log all LLM prompts and responses to file.txt
python examples/basic_usage.py --trace --trace-filename mylog.txt   # Log LLM traces to custom file
python examples/basic_usage.py --debug --trace               # Combine step-through and trace logging
```

- The `--debug` flag enables step-through mode, which pauses execution at each agent reasoning step for inspection.
- The `--trace` flag logs all LLM prompts and responses to a file (default: `file.txt`).
- The `--trace-filename` flag lets you specify a custom trace log file (used with `--trace`).
- Both flags can be combined.
- By default, both are off and the trace filename is `file.txt`.

### Running Tests

Integration tests are provided using Python's `unittest` framework:

```bash
python -m unittest discover tests
```

Development checks (run from project root):
```bash
black --check gpt_agents_py examples tests
isort --check gpt_agents_py examples tests
flake8 gpt_agents_py examples tests
mypy gpt_agents_py examples tests
```

### Continuous Integration

This project uses [GitHub Actions](.github/workflows/python-app.yml) to automatically lint, type-check, and run tests on pushes and pull requests to `main`, across Python 3.11 and 3.12.

### Example: Defining Agents, Tools, and Running an Organization

```python
from gpt_agents_py.gpt_agents import Agent, Organization, Task, Tool, organization_executor

def population_tool(args):
    country = args.get("country")
    return {"france": 67000000, "germany": 83000000}.get(country.lower(), "unknown")

def calculator_tool(args):
    op = args["operation"]
    a, b = float(args["a"]), float(args["b"])
    if op == "add": return str(a + b)
    if op == "subtract": return str(a - b)
    if op == "multiply": return str(a * b)
    if op == "divide": return str(a / b)
    return "unknown"

agent = Agent(
    role="Researcher",
    goal="Find population and add 1000",
    backstory="Expert in demographics.",
    tasks=[Task(name="GetPop", description="Get France's population", expected_output="67000000")],
    tools=[
        Tool(name="PopulationTool", description="Returns country population", args_schema="country:str", func=population_tool),
        Tool(name="Calculator", description="Performs arithmetic", args_schema="operation:str, a:str, b:str", func=calculator_tool)
    ]
)
org = Organization(agents=[agent])
result = organization_executor(org)
print(result)
```

See `gpt_agents_py/examples.py` for a more complete demo.

## Testing

Integration tests are provided in the `tests/` directory. LLM calls are mocked for deterministic testing, and real tool logic is exercised.

To run all tests:

```bash
python -m unittest discover tests
```

See `tests/test_integration.py` for an example of integration testing with mocked LLM calls.
