Lineage Suggestion Agent

An AI-powered assistant that provides friendly, context-aware guidance to users navigating a data lineage workflow.

Description

This agent acts as a virtual assistant within a data lineage application. It takes the current status of the user's workflow as input and uses a large language model (LLM) to generate a concise, encouraging, and actionable suggestion for the next logical step.

The primary goal is to enhance the user experience by providing clear, timely guidance, reducing confusion, and helping users move smoothly through complex data lineage tasks.

Key Features

• Context-Aware Guidance: Analyzes the current workflow status to provide relevant suggestions.
• Friendly & Actionable: Generates suggestions that are easy to understand and act upon.
• Encouraging Tone: Uses positive language to motivate users as they make progress.
• Simple Integration: Designed to be easily integrated into any application requiring guided user interaction.

Installation

Prerequisites

• uv – A fast Python package and environment manager.
• Git

Steps

1. Clone the lineage_suggestion_agent repository:

   git clone https://github.com/stepfnAI/lineage_suggestion_agent.git
   cd lineage_suggestion_agent
   

2. Create a virtual environment and install dependencies:

   git switch dev
   uv sync --extra dev
   source .venv/bin/activate
   

3. Clone and install the sfn_blueprint dependency: The agent requires the sfn_blueprint library.

   cd ../
   git clone https://github.com/stepfnAI/sfn_blueprint.git
   cd sfn_blueprint
   git switch dev
   uv pip install -e .
   cd ../lineage_suggestion_agent
   

Configuration

Configure the agent by creating a .env file in the project root or by exporting environment variables.

Available Settings

Environment Variable	Description	Default
OPENAI_API_KEY or ANTHROPIC_API_KEY	(Required) Your AI provider API key.	None
LINEAGE_AI_PROVIDER	AI provider for suggestions.	openai
LINEAGE_MODEL	AI model for suggestions.	gpt-4o
LINEAGE_TEMPERATURE	AI model temperature (0.0 to 2.0).	0.3
LINEAGE_MAX_TOKENS	Maximum tokens for the AI response.	4000

Example .env file:

# .env
OPENAI_API_KEY="sk-your-openai-api-key-here"

# Optional: Use a different model
# LINEAGE_MODEL="gpt-4o-mini"

Testing

To run the test suite, use the following command from the project root:

pytest

Usage

Running the Example Script

A basic usage example is provided in the examples/ directory.

python examples/basic_usage.py

Using as a Library

Integrate the LineageSuggestionAgent directly into your application.

from lineage_suggestion_agent import LineageSuggestionAgent

# 1. Initialize the agent
agent = LineageSuggestionAgent()

# 2. Define the current workflow status as a context string
context = "Join and transformations on 'Entity_X' are complete, creating 'Table_A'. Next action: MarkAsFinal."

# 3. Call the agent to get a suggestion
suggestion, cost = agent({"context": context})

# 4. Print the results
print(f"Suggestion: {suggestion.answer}")
print(f"Cost Details: {cost}")

Example Output

The agent returns a LineageSuggestion object and a cost dictionary.

Suggestion: Great job on completing the join and transformations for 'Entity_X'! Now, let's finalize this table. Please use the 'MarkAsFinal' action to complete the process.
Cost Details: {'prompt_tokens': 457, 'completion_tokens': 41, 'total_tokens': 498, 'total_cost_usd': 0.0016}
