# Contact CRM This skill provides a complete contact-product-organization management system using CSV files with relational linking via UUIDs. Three normalized entities with auto-export to PDF and XLSX. ## Data model ``` Organization ──1:N──→ Contact ──N:N──→ Product ``` - **Organization**: company or entity with address, industry, tax info - **Contact**: person linked to one organization - **Product**: catalog item referenced by contacts via `product_ids` ## When to install dependencies If you only need the CSV schema or pattern, no installation needed. If you need validation, CRUD operations, or export, install dependencies: ```bash pip install -r requirements.txt ``` Scripts auto-detect missing dependencies and install them on first run. ## How to use this skill 1. **Scaffold**: `python scripts/scaffold.py` — generates empty CSVs with correct headers 2. **Organizations**: `python scripts/organizations.py add|list|search|update` 3. **Contacts**: `python scripts/contacts.py add|list|search|update` 4. **Products**: `python scripts/products.py add|list|search|update` 5. **Validate**: `python scripts/validate.py` — checks phone numbers + cross-CSV references 6. **Export**: `python scripts/export.py` — generates PDF and XLSX All CRUD operations auto-trigger export after every save. ## Quick reference ```bash # Scaffold empty CSVs python scripts/scaffold.py # Create an organization python scripts/organizations.py add # Create a contact (note the org UUID from previ
