chief-ai 0.1.1

AI agent framework with Chief and Chen, a conversational AI psychologist with web search and multi-provider support in your terminal.

Chief & Chen AI Agents

A sophisticated AI agent framework built with Pydantic AI, featuring two main applications: Chief and Chen. Both agents provide conversational AI interfaces with web search capabilities and configurable model providers.

Chen has been written as an AI psychologist with an extensive software engineering background. You can think of her like Wendy Rhoades that is always on your side.

On the other hand, Chief is a barebone agent with a barebone system prompt. Chief provides an entry point if you want to write your own agents using the same patterns that Chen uses.

Features

• Dual Agent System: Chief and Chen applications with distinct personalities and capabilities
• Multi-Provider Support: Anthropic, OpenAI, and OpenRouter integration
• Web Search Integration: Powered by Tavily API for real-time information
• Smart Configuration: Interactive onboarding with JSON-based settings management
• MongoDB Persistence: Async document storage with Beanie ODM Not implemented yet
• Rich CLI Interface: Beautiful terminal UI with Typer and Rich
• MCP Support: Coming soon

Quick Start

Installation

# Clone and setup
git clone [e-mail]:tistaharahap/chief-ai.git
cd chief
source .venv/bin/activate

First Run (Chief)

# Launch Chief
rye run chief

LLM Providers & Models Priority

In src/libagentic/providers.py, it is clear that the first choice is Anthropic's Claude 4 Sonnet.

If the anthropic_api_key in ~/.chen/settings.json is set, Claude 4 Sonnet will be the first choice. When all providers are set, the fallback becomes:

1. claude-sonnet-4-20250514 via Anthropic
2. gpt-5 via OpenAI
3. deepseek/deepseek-chat-v3.1:free via OpenRouter

To use free models, simply set the OpenRouter API key and leave the others unset.

Configuration

Chen Configuration System

Chen uses a sophisticated JSON-based configuration system with interactive onboarding:

# View current settings
rye run chen config

# Set individual values
rye run chen config set anthropic_api_key "sk-ant-..."
rye run chen config set context_window 150000

# Manual onboarding
rye run chen onboard

# Reset all settings
rye run chen reset

Settings are stored in ~/.chen/settings.json with support for:

• Anthropic, OpenAI, OpenRouter, and Tavily API keys
• Configurable context window size
• Automatic validation and type conversion

Environment Variables (Optional)

Environment variables serve as defaults during onboarding:

export ANTHROPIC_API_KEY="your-key-here"
export OPENAI_API_KEY="your-key-here"
export OPENROUTER_API_KEY="your-key-here"
export TAVILY_API_KEY="your-key-here"
