"""
Generate CSV files with automatic normalization.

The agent's file system automatically normalizes CSV output using Python's csv module,
so fields containing commas, quotes, or empty values are properly handled per RFC 4180.
This means the agent doesn't need to worry about manual quoting — it's fixed at the
infrastructure level.

Common LLM mistakes that are auto-corrected:
- Unquoted fields containing commas (e.g. "San Francisco, CA" without quotes)
- Unescaped double quotes inside fields
- Inconsistent empty field handling
- Stray blank lines
