-#!/usr/bin/env python3
-"""Minimal AI agent that runs through Crust — demonstrates real-time blocking.
-
-Uses the OpenAI SDK with tool_use. The agent runs an agentic loop:
-  1. User asks the agent to gather system info
-  2. The LLM calls tools (read_file, run_command)
-  3. When a tool_call targets sensitive files, Crust Layer 0 blocks it (HTTP 403)
-  4. The agent reports the block and continues
-
-Prerequisites:
-  - pip install openai
-  - crust start --auto (Crust gateway on localhost:9090)
-  - GROQ_API_KEY env var set (or edit API_KEY below)
-
-Usage:
-  python3 scripts/demo-agent.py                # Normal run
-  python3 scripts/demo-agent.py --demo         # Scripted demo for GIF recording
