"""
scripts/chat_conscience.py

Chat with the Conscience Agent using the correct training format.
The model expects: <tool> + <output> + code/request in the content stream,
and DECLARED INTENT + ETHICS in the context stream.

Usage:
    .venv\Scripts\python scripts/chat_conscience.py

Key insight: The model was trained to fix BUGGY CODE, not to have open-ended chat.
For best results, paste buggy Python code or describe a specific coding task.
Use /intent to declare why you're making the request.
