  Handle PDF manipulation, form filling, text/table extraction, and high-fidelity generation. Use for professional PDF reports, merging documents, and automated form processing. Use proactively when visual quality and verification are critical.
  
  Examples:
  - user: "Fill this PDF form and verify" -> populate fields and inspect images
  - user: "Merge these reports and add a watermark" -> use pypdf
  - user: "Extract this complex table to Excel" -> use pdfplumber for layout preservation

🛠 High-Fidelity Creation

When generating polished reports:

  1. •Generate: Use Reportlab (programmatic) or Platypus (templated) as the primary engine.
  2. •Preview: Convert every page to PNG for inspection:
    • •pdftoppm -png -r 150 document.pdf page
  3. •Inspect: Verify that charts, tables, and typography are sharp and well-aligned.

📋 Common Operations

1. Form Filling

  • •Identify fillable fields using scripts/extract_form_field_info.py.
  • •Reference: See references/forms.md for detailed instructions on filling PDF forms.
  • •Populate fields programmatically and verify using the Render loop.

2. Manipulation (pypdf)

  • •Merge: Use PdfWriter to combine multiple documents.
  • •Split: Extract individual pages into new files.
  • •Secure: Add passwords or watermarks using PdfWriter.encrypt().
  • •Reference: See references/reference.md for advanced features and JS library alternatives.

3. Extraction (pdfplumber)

  • •Extract text with layout preservation.
  • •Extract complex tables directly into Pandas DataFrames for analysis.

💎 Quality Expectations

  • •Legibility: Text must be readable at 100% zoom; avoid walls of dense text.
  • •Polish: Maintain intentional visual design—consistent margins and color palettes.
  • •Verification: Zero defects (black squares, clipped text) permitted in final output.
