+# Scripts
+
+This directory contains executable scripts for deterministic, repeatable tasks.
+
+## Guidelines
+
+- Scripts should be self-contained and well-documented
+- Include usage examples in script headers
+- Handle errors gracefully with clear messages
+- Use appropriate exit codes (0 for success, 1 for failure)
+
+## Files
+
+Add your scripts here. Examples:
+- `generate.py` - Main generation script
+- `validate.py` - Validation utilities
+- `transform.py` - Data transformation helpers
