"""
Autonomous Agent Demo - REAL Validation with GPT-4

Demonstrates:
1. Objective Convergence Detection (while(tool_call_exists) pattern)
2. Real Tool Execution (file operations, NO MOCKING)
3. Multi-Cycle Autonomous Operation
4. MCP + Custom Tool Integration

Requirements:
- OPENAI_API_KEY in /Users/esperie/repos/dev/kailash_python_sdk/.env
- Uses GPT-3.5-turbo for real inference
- Real file system operations
- No mocks, simulations, or hardcoding
