Quick Start

Set Environment Variables

Choose one LLM provider and set the corresponding API key:

# 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

mixseek init

This creates sample configuration files in your workspace:

# 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" \
