Henchman-AI

Your AI Henchman for the Terminal - A Model-Agnostic AI Agent CLI

Henchman-AI is a powerful, terminal-based AI agent that supports multiple LLM providers (DeepSeek, OpenAI, Anthropic, Ollama, and more) through a unified interface. Inspired by gemini-cli, built for extensibility and production use.

✨ Features

• 🤝 Multi-Agent Dev Team: Orchestrate a team of specialists (Architect, Coder, Reviewer, Tester, etc.) to solve complex engineering tasks.
• 🔄 Model-Agnostic: Support any LLM provider through a unified abstraction layer
• 🐍 Pythonic: Leverages Python's async ecosystem and rich libraries for optimal performance
• 🔌 Extensible: Plugin system for tools, providers, and custom commands
• 🚀 Production-Ready: Proper error handling, comprehensive testing, and semantic versioning
• 🛠️ Tool Integration: Built-in support for file operations, web search, code execution, and more
• ⚡ Fast & Efficient: Async-first design with intelligent caching and rate limiting
• 🔒 Secure: Environment-based configuration and safe execution sandboxing

📦 Installation

From PyPI (Recommended)

pip install henchman-ai

From Source

git clone https://github.com/MGPowerlytics/henchman-ai.git
cd henchman-ai
pip install -e ".[dev]"

With uv (Fastest)

uv pip install henchman-ai

🚀 Quick Start

1. Set your API key (choose your preferred provider):

   export DEEPSEEK_API_KEY="your-api-key-here"
   # or
   export OPENAI_API_KEY="your-api-key-here"
   # or
   export ANTHROPIC_API_KEY="your-api-key-here"
   

2. Start the CLI:

   henchman
   

3. Or run with a prompt directly:

   henchman --prompt "Explain this Python code" < example.py
   

📖 Usage Examples

Basic Commands

# Show version
henchman --version

# Show help
henchman --help

# Interactive mode (default)
henchman

# Headless mode with prompt
henchman -p "Summarize the key points from README.md"

# Specify a provider
henchman --provider openai -p "Write a Python function to calculate fibonacci"

# Use a specific model
henchman --model gpt-4-turbo -p "Analyze this code for security issues"

File Operations

# Read and analyze a file
henchman -p "Review this code for bugs" < script.py

# Process multiple files
cat *.py | henchman -p "Find common patterns in these files"

# Generate documentation
henchman -p "Create API documentation for this module" < module.py > docs.md

⚙️ Configuration

Henchman-AI uses hierarchical configuration (later settings override earlier ones):

1. Default settings (built-in sensible defaults)
2. User settings: ~/.henchman/settings.yaml
3. Workspace settings: .henchman/settings.yaml (project-specific)
4. Environment variables (highest priority)

Example settings.yaml

# Provider configuration
providers:
  default: deepseek  # or openai, anthropic, ollama
  deepseek:
    model: deepseek-chat
    base_url: "https://api.deepseek.com"
    temperature: 0.7
  openai:
    model: gpt-4-turbo-preview
    organization: "org-xxx"

# Tool settings
tools:
  auto_accept_read: true
  shell_timeout: 60
  web_search_max_results: 5

# UI settings
