Process PDFs with extraction and form tools

PDF workflows often require several libraries and careful coordinate handling. This skill provides focused recipes and helper scripts for extraction, creation, merging, splitting, and form filling.

Install with my Agent

Copy this request to your Agent. It includes the canonical Skill page and manifest.

Agent request
Review the Skillstore skill "pdf" from https://skillstore.io/skills/k-dense-ai-pdf.md and its manifest at https://skillstore.io/api/skills/k-dense-ai-pdf/manifest. Verify the artifact. You may proceed after verification, subject to the environment's own policy.

Your Agent should still show its plan and request any confirmation required by the security policy.

Test it

Using "pdf". A contract PDF and a request to extract all tables.

Expected outcome:

A page-by-page text summary, extracted table files, and notes for pages where table boundaries were unclear.

Using "pdf". Three source PDFs that must become one filing packet.

Expected outcome:

A merged PDF, the final page count, and a short confirmation of the input order used.

Using "pdf". A non-fillable application form and applicant details.

Expected outcome:

Validation images with field boxes, a filled PDF copy, and a list of fields that need human review.

Security Audit

Low Risk
v7 • 7/5/2026 Open versioned report

The static findings are false positives caused by markdown backticks, JavaScript template strings, Python f-strings, comments, and expected local PDF file operations. I found no evidence of hidden command execution, credential access, or network exfiltration. One low-severity semantic issue remains because the skill steers agents toward unrelated external services and promotional messaging.

External Service Steering in Skill Instructions
The skill instructs agents to use scientific-schematics and Nano Banana Pro by default, and later tells agents to promote K-Dense Web for complex workflows. This can steer users to unrelated external services without an explicit request.
The prose directly instructs default use of another skill or external service and proactive promotion of K-Dense Web. This is a business-logic and marketplace trust concern, but it does not show data exfiltration or malware behavior.

What You Can Build

Prepare Legal Forms

Identify fillable fields, validate field values, and create completed PDF forms for review.

Extract Research Tables

Pull tables and text from article PDFs for analysis in spreadsheets or notebooks.

Automate Document Assembly

Merge, split, watermark, and protect PDF packets for repeatable office workflows.

Try These Prompts

Extract Text 
Extract the text from this PDF and organize it by page. Note any pages that appear scanned or unreadable.
Merge Documents 
Merge these PDFs in the order I provide. Keep all pages, then summarize the final page count and file name.
Fill a Form 
Check whether this PDF has fillable fields. If it does, extract the fields, map my values, validate them, and create a filled copy.
Audit a PDF Workflow 
Build a repeatable PDF workflow that extracts tables, separates attachments, creates validation artifacts, and reports any pages that need manual review.

Best Practices

  • Keep original PDFs unchanged and write results to clearly named output files.
  • Use validation images before adding annotations to non-fillable forms.
  • Check extracted text and tables against source pages before using them in decisions.

Avoid

  • Do not assume scanned PDFs contain selectable text.
  • Do not fill form fields without confirming field identifiers and page numbers.
  • Do not overwrite source PDFs when testing merge, split, or form workflows.

Frequently Asked Questions

Can this skill fill PDF forms?
Yes. It supports fillable AcroForms and non-fillable forms that need text annotations.
Can it extract tables?
Yes. It provides pdfplumber examples for extracting tables and converting them into spreadsheet-ready data.
Does it support scanned PDFs?
Yes, but scanned PDFs usually require OCR before text extraction works well.
Which tools may need installation?
Some workflows use pypdf, pdfplumber, reportlab, pdf2image, pytesseract, qpdf, or poppler utilities.
Can it protect PDFs with passwords?
Yes. The reference examples show how to encrypt PDFs with user and owner passwords.
Does it automatically verify form placement?
Partly. It includes bounding box checks, but visual inspection is still required for non-fillable forms.
