Valthera is an open-source framework that empowers LLM Agents to drive meaningful, context-aware user engagement. It evaluates user motivation and ability in real time, ensuring that notifications and actions are triggered only when users are most receptive. langchain-valthera integrates Valthera with LangChain, enabling developers to build smarter, behavior-driven engagement systems that deliver personalized interactions.

​
Installation and Setup

​
Install langchain-valthera

Install the LangChain Valthera package via pip: 
pip install -U langchain-valthera
Import the ValtheraTool: 
from langchain_valthera.tools import ValtheraTool

​
Example: Initializing the ValtheraTool for LangChain

This example shows how to initialize the ValtheraTool using a DataAggregator and configuration for motivation and ability scoring. 
import os
from langchain_openai import ChatOpenAI
from valthera.aggregator import DataAggregator
from mocks import hubspot, posthog, snowflake  # Replace these with your actual connector implementations
from langchain_valthera.tools import ValtheraTool

# Initialize the DataAggregator with your data connectors
data_aggregator = DataAggregator(
    connectors={
        "hubspot": hubspot(),
        "posthog": posthog(),
        "app_db": snowflake()
    }
)

# Initialize the ValtheraTool with your scoring configurations
valthera_tool = ValtheraTool(
    data_aggregator=data_aggregator,
    motivation_config=[
        {"key": "hubspot_lead_score", "weight": 0.30, "transform": lambda x: min(x, 100) / 100.0},
        {"key": "posthog_events_count_past_30days", "weight": 0.30, "transform": lambda x: min(x, 50) / 50.0},
        {"key": "hubspot_marketing_emails_opened", "weight": 0.20, "transform": lambda x: min(x / 10.0, 1.0)},
        {"key": "posthog_session_count", "weight": 0.20, "transform": lambda x: min(x / 5.0, 1.0)}
    ],
    ability_config=[
        {"key": "posthog_onboarding_steps_completed", "weight": 0.30, "transform": lambda x: min(x / 5.0, 1.0)},
        {"key": "posthog_session_count", "weight": 0.30, "transform": lambda x: min(x / 10.0, 1.0)},
        {"key": "behavior_complexity", "weight": 0.40, "transform": lambda x: 1 - (min(x, 5) / 5.0)}
    ]
)

print("✅ ValtheraTool successfully initialized for LangChain integration!")
The langchain-valthera integration allows you to assess user behavior and decide on the best course of action for engagement, ensuring that interactions are both timely and relevant within your LangChain applications.
