When users upload files, categorize them into the appropriate `/documents/` subfolder based on content:

## Folder Mapping

- **documents/career/** - CV, resume, cover letters, certifications, job-related documents
- **documents/identity/** - LinkedIn exports, personal bios, about-me documents, writing samples, blog posts
- **documents/work/** - Portfolio pieces, project documentation, work samples, case studies
- **documents/notes/** - Meeting notes, research, saved articles, reference materials

## Process

1. Read the uploaded file content
2. Determine the most appropriate category based on what the file contains
3. Save to the matching folder with a descriptive filename
4. Confirm where the file was saved
5. Ask if they want to upload more files

## Tips

- If a file could fit multiple categories, choose based on primary purpose
- Preserve original filenames when they're descriptive
- For ambiguous files, briefly explain why you chose that category
