rakam-systems-agent 0.1.2rc4

AI Agents framework with Pydantic AI support and LLM Gateway integration

Rakam Systems Agent

The agent package of Rakam Systems providing AI agent implementations powered by Pydantic AI.

Overview

rakam-systems-agent provides flexible AI agents with tool integration, chat history, and LLM gateway abstractions. This package depends on rakam-systems-core.

Features

• Configuration-First Design: Change agents without code changes — just update YAML files
• Async/Sync Support: Full support for both synchronous and asynchronous agent operations
• Tool Integration: Easy tool definition and integration using the Tool.from_schema pattern
• Model Settings: Control model behavior including parallel tool calls, temperature, and max tokens
• Pydantic AI Powered: Built on top of Pydantic AI library
• Streaming Support: Both sync and async streaming interfaces
• Chat History: Multiple backends (JSON, SQLite, PostgreSQL)
• LLM Gateway: Unified interface for OpenAI and Mistral AI

Quick Start

import asyncio
from rakam_systems_agent import BaseAgent
from rakam_systems_core.ai_core.interfaces import ModelSettings
from rakam_systems_core.ai_core.interfaces.tool import ToolComponent as Tool

async def get_weather(city: str) -> dict:
    """Get weather information for a city"""
    return {"city": city, "temperature": 72, "condition": "sunny"}

agent = BaseAgent(
    name="weather_agent",
    model="openai:gpt-4o",
    system_prompt="You are a helpful weather assistant.",
    tools=[
        Tool.from_schema(
            function=get_weather,
            name='get_weather',
            description='Get weather information for a city',
            json_schema={
                'type': 'object',
                'properties': {
                    'city': {'type': 'string', 'description': 'The city name'},
                },
                'required': ['city'],
                'additionalProperties': False,
            },
            takes_ctx=False,
        ),
    ],
)

async def main():
    result = await agent.arun(
        "What's the weather in San Francisco?",
        model_settings=ModelSettings(parallel_tool_calls=True),
    )
    print(result.output_text)

asyncio.run(main())

Core Components

• BaseAgent — Primary agent implementation powered by Pydantic AI, with tool support and streaming
• Tool — Wrapper for tool functions using Tool.from_schema pattern
• ModelSettings — Configure parallel tool calls, temperature, max tokens
• LLM Gateway — Provider-agnostic interface for OpenAI and Mistral (details)
• Chat History — JSON, SQLite, and PostgreSQL backends
• MCP Server — Message-based component registry for agent tools (details)

Contributing

When adding new agent types:

1. Inherit from BaseAgent
2. Implement ainfer() for async or infer() for sync
3. Add tests in tests/
