pdfPDF is an Agent Skill for documents published in the Hmbown/CodeWhale repository on GitHub: a SKILL.md instruction file an AI agent can load to do this task.
Read, extract, split, merge, rotate, watermark, fill, OCR, or create PDF files with verification of page counts and text extraction.
QUICK START
How to use this skill
Bring this guide into your coding agent with a prompt tailored to the tool you use.
- Open your project in Codex.
- Copy and paste the prompt below.
- Review files and risks before approving any action.
Prompt to paste
Inspect the Agent Skill at https://github.com/Hmbown/CodeWhale/blob/HEAD/crates/tui/assets/skills/pdf/SKILL.md and all supporting files. Report provenance, permissions, scripts, dependencies, and security risks. Propose an exact installation into .agents/skills/pdf, but wait for my approval before writing files or running scripts.
Copying this prompt does not install or run the skill. Review third-party files before use.
Use this skill for any task where a PDF is the primary input or output.
Workflow
- Identify the PDF operation: read, extract, OCR, split, merge, rotate, watermark, redact, fill forms, encrypt/decrypt, or create.
- Preserve originals. Write outputs with explicit names.
- Use the most reliable available tool:
- DeepSeek's file reader for basic text extraction from PDFs
pdftotext,pdfinfo,qpdf, ormutoolwhen installed- Python libraries such as
pypdf,pdfplumber,PyMuPDF, orreportlabwhen available - OCR tools only for scanned pages
- For extraction, report page coverage and note when layout, tables, or OCR quality may affect accuracy.
- For generated or modified PDFs, verify page count, text extraction where possible, and file size. For redaction, confirm removed text is not extractable from the output.
Ask before installing dependencies or running OCR over large documents. Do not represent a visually scanned PDF as fully accurate text unless OCR quality has been checked.
