Architecture

The system uses:

• FastAPI for the web server
• LangGraph for the multi-agent architecture
• Claude's API for agent intelligence
• browser-use for web automation

The workflow consists of:

1. Master Agent: Analyzes the task and creates a plan
2. Execution Agent: Carries out the plan using available tools
