railtracks 1.1.5

The RailTracks Framework for building resilient agentic systems in simple python

Quick Start

Build your first agentic system in just a few steps. Start by building an agent which solves the "how many r's are in Strawberry?" problem.

Step 1: Install the Library

# Core library
pip install railtracks

# [Optional] CLI support for development and visualization
pip install railtracks-cli

Step 2: Define Your Modular Components

import railtracks as rt

# Create your tool
@rt.function_node
def number_of_characters(text: str, character_of_interest: str) -> int:
    return text.count(character_of_interest)

# Create your agent (connecting your LLM)
TextAnalyzer = rt.agent_node(
    tool_nodes={number_of_chars, num, CharacterCount},
    llm=rt.llm.OpenAILLM("gpt-4o"),
    system_message=(
        "You are a text analyzer. You will be given a text and return the number of characters, "
        "the number of words, and the number of occurrences of a specific character."
    ),
)

Step 3: Run Your Application

@rt.session
async def main():
    result = await rt.call(
        TextAnalyzer,
        rt.llm.MessageHistory([
            rt.llm.UserMessage("Hello world! This is a test of the RailTracks framework.")
        ])
    )
    print(result)

Step 4: [Optional] Visualize the Run

railtracks init
railtracks viz

And just like that, you're up and running. The possibilities are endless.
