Chat-to-Action CLI for Hevo Data pipelines with RAG-powered assistance

Hevo Assistant

A chat-to-action CLI tool for managing Hevo Data pipelines using natural language. Ask questions, check status, pause/resume pipelines, and more - all through conversation.

Features

• Natural Language Interface: Interact with your Hevo pipelines using plain English
• RAG-Powered Responses: Get accurate answers based on Hevo documentation
• Multiple LLM Providers: Choose between OpenAI, Anthropic Claude, or local Ollama
• Pipeline Management: List, pause, resume, and run pipelines
• Model & Workflow Support: Manage dbt models and workflows
• Secure Configuration: Credentials stored locally in ~/.hevo/
• Fast Installation: ~30 seconds (no heavy ML dependencies)

Installation

pip install hevo-assistant

That's it! Installation is fast because we use cloud services (Pinecone + OpenAI) instead of local ML models.

For Development

git clone https://github.com/Legolasan/hevo-app.git
cd hevo-app
pip install -e .

Optional: Local RAG (Heavy)

If you prefer to run embeddings locally (offline mode), install with:

pip install hevo-assistant[local-rag]

Note: This adds ~2GB of dependencies (PyTorch, sentence-transformers).

Quick Start

1. Setup Configuration

Run the interactive setup wizard:

hevo setup

You'll be prompted for:

• Hevo API credentials: Get from Hevo Dashboard > Settings > API Keys
• LLM provider: Choose OpenAI, Anthropic, or Ollama
• LLM API key: Your provider's API key (not needed for Ollama)
• Pinecone API key: Get free at pinecone.io

2. Start Chatting

# Interactive chat mode
hevo chat

# Or ask a one-shot question
hevo ask "List my pipelines"

Usage Examples

# Check pipeline status
hevo ask "What's the status of my Salesforce pipeline?"

# List all pipelines
hevo ask "Show me all my pipelines"

# Pause a pipeline
hevo ask "Pause the MySQL pipeline"

# Resume a pipeline
hevo ask "Resume the MySQL pipeline"

# Run a pipeline now
hevo ask "Run the Salesforce pipeline now"

# Ask about Hevo features
hevo ask "How do I create a new destination?"

# List models
hevo ask "What models do I have?"

# Run a model
hevo ask "Run my revenue model"
