# Project Structure Rules
## Directory Organization
### Root Level
- `/src/project_name_placeholder/` - Main package code
- `/src/` - Main notebook code (.ipynb) and Python files that will be called directly
- `/tests/` - Test files
- `/docs/` - Documentation
- `/scripts/` - Development and setup scripts ONLY
- `/data/` - Internal data ONLY (no scripts)
- Configuration files (setup.py, requirements.txt, etc.)
### Scripts Location
- ALL scripts must be in `/scripts/`
- NEVER put scripts in `/data/`, unless they are data generation scripts
- NO OTHER DIRECTORIES ALLOWED
### Script Categories
Development scripts in `/scripts/`:
- Installation scripts
- Setup scripts
- Development utilities
- Build scripts
- Test runners
## File Organization
- Python package code goes in `src/project_name_placeholder/`
- Tests go in `tests/`
- Documentation in `docs/`
- Development scripts in `scripts/`
- Data files in `/data/`
## Naming Conventions
- Python files: lowercase with underscores
- Scripts: descriptive names with appropriate extensions
- Test files: prefix with `test_`
- Log files: descriptive with date stamps
- Database/Data files: clear purpose in filename
