• General file operations → use Bash or file tools

Decision Framework

PDF Operation?
├── Generate from scratch
│   ├── Simple → PDFKit (Node) / ReportLab (Python)
│   └── Complex layouts → Puppeteer/Playwright + HTML
├── Parse/Extract
│   ├── Text extraction → pdf-parse / PyPDF2
│   └── Table extraction → Camelot / Tabula
├── Manipulate
│   └── pdf-lib (merge, split, edit)
└── Forms
    └── pdf-lib (fill) / PDFtk (advanced)

Core Workflows

1. PDF Generation with PDFKit

1. Install PDFKit (

   npm install pdfkit

   )
2. Create new PDDocument
3. Add content (text, images, graphics)
4. Style with fonts and colors
5. Add pages as needed
6. Pipe to file or response

2. HTML to PDF Conversion

1. Set up Puppeteer/Playwright
2. Navigate to HTML content or URL
3. Configure page size and margins
4. Set print options (headers, footers)
5. Generate PDF buffer
6. Save or stream result

3. PDF Parsing and Extraction

1. Choose parser (pdf-parse, PyPDF2, pdfplumber)
2. Load PDF file
3. Extract text or structured data
4. Handle multi-page documents
5. Clean and normalize extracted text
6. Output in desired format

Best Practices

• Use vector graphics over raster when possible
• Embed fonts for consistent rendering
• Test PDF output across different readers
• Handle large PDFs with streaming
• Use appropriate library for task complexity
• Consider accessibility (tagged PDFs)
