A multi-agent orchestration framework for LLM-powered workflows. MixSeek enables hierarchical task delegation with Leader and Member agents, round-based evaluation, and parallel team execution.

## Features

- Multi-agent orchestration with Leader/Member hierarchy
- Support for multiple LLM providers (Google, OpenAI, Anthropic, xAI)
- Round-based evaluation with customizable judgment criteria
- Parallel team execution with leaderboard ranking
- Streamlit-based web UI for execution monitoring
- CLI tools for workspace management and agent execution

## Installation

### As a CLI Tool (Recommended)

Install globally as a command-line tool using `uv`:

```bash
# Install as a CLI tool (requires uv)
uv tool install mixseek-core

# Or install from source
git clone https://github.com/mixseek/mixseek-core.git
cd mixseek-core
uv tool install .
```

After installation, `mixseek` commands will be available globally:

```bash
mixseek --version
```

### As a Python Package

Install as a library for programmatic use:

```bash
# Using pip
pip install mixseek-core

# Using uv
uv pip install mixseek-core

# Add to project dependencies (uv)
uv add mixseek-core
```

For development setup, see [Development Guide](https://mixseek.github.io/mixseek-core/developer-guide.html).

## Quick Start

### Set Environment Variables

Choose one LLM provider and set the corresponding API key:

```bash
# Workspace directory (required)
export MIXSEEK_WORKSPACE=$HOME/mixseek-workspace

# Google Gemini (default in sample configs)
export GOOGLE_API_KEY=your-api-key

# OpenAI
export OPENAI_API_KEY=your-api-key

# Anthropic
export ANTHROPIC_API_KEY=your-api-key

# xAI (Grok)
export GROK_API_KEY=your-api-key
```

### Initialize Workspace

```bash
mixseek init
```

This creates sample configuration files in your workspace:
- `configs/search_news.toml` - Simple orchestrator
- `configs/search_news_multi_perspective.toml` - Multi-team orchestrator
- `configs/agents/` - Team configurations

### Run Orchestration

```bash
# Execute with orchestrator config
mixseek exec "Search for the latest AI news" \
  --config $MIXSEEK_WORKSPACE/configs/search_news.toml

# Run single team
mixseek team "Analyze this topic" \
  --config $MIXSEEK_WORKSPACE/configs/agents/team_general_researcher.toml

# Launch web UI
mixseek ui
```
