Skill for using the command-line tool pdftk (PDFtk Server) for working with PDF files. Use when asked to merge PDFs, split PDFs, rotate pages, encrypt or decrypt PDFs, fill PDF forms, apply watermarks, stamp overlays, extract metadata, burst documents into pages, repair corrupted PDFs, attach or extract files, or perform any PDF manipulation from the command line.

PDFtk Server is a command-line tool for working with PDF documents. It can merge, split, rotate, encrypt, decrypt, watermark, stamp, fill forms, extract metadata, and manipulate PDFs in a variety of ways.
winget install --id PDFLabs.PDFtk.Serverbrew install pdftk-javasudo apt-get install pdftksudo dnf install pdftkpdftk --versionpdftk file1.pdf file2.pdf cat output merged.pdf
Using handles for more control:
pdftk A=file1.pdf B=file2.pdf cat A B output merged.pdf
pdftk input.pdf burst
Extract pages 1-5 and 10-15:
pdftk input.pdf cat 1-5 10-15 output extracted.pdf
Remove page 13:
pdftk input.pdf cat 1-12 14-end output output.pdf
Rotate all pages 90 degrees clockwise:
pdftk input.pdf cat 1-endeast output rotated.pdf
Set an owner password and a user password with 128-bit encryption (default):
pdftk input.pdf output secured.pdf owner_pw mypassword user_pw userpass
Remove encryption using the known password:
pdftk secured.pdf input_pw mypassword output unsecured.pdf
Populate form fields from an FDF file and flatten to prevent further edits:
pdftk form.pdf fill_form data.fdf output filled.pdf flatten
Place a single-page PDF behind every page of the input (input should have transparency):
pdftk input.pdf background watermark.pdf output watermarked.pdf
Place a single-page PDF on top of every page of the input:
pdftk input.pdf stamp overlay.pdf output stamped.pdf
Export bookmarks, page metrics, and document information:
pdftk input.pdf dump_data output metadata.txt
Pass a broken PDF through pdftk to attempt automatic repair:
pdftk broken.pdf output fixed.pdf
Interleave separately scanned even and odd pages:
pdftk A=even.pdf B=odd.pdf shuffle A B output collated.pdf
| Issue | Solution |
|---|---|
pdftk command not found | Verify installation; check that pdftk is in your system PATH |
| Cannot decrypt PDF | Ensure you are providing the correct owner or user password via input_pw |
| Output file is empty or corrupt | Check input file integrity; try running pdftk input.pdf output repaired.pdf first |
| Form fields not visible after fill | Use the flatten flag to merge fields into the page content |
| Watermark not appearing | Ensure the input PDF has transparent regions; use stamp for opaque overlays |
| Permission denied errors | Check file permissions on input and output paths |

概要と使いどころ
Use when long-lived agents, project memories, system prompts, or playbooks are repeatedly summarized, rewritten, or optimized and risk losing domain detail, provenance, or execution learnings.

Use this skill when the user explicitly asks to map, document, or onboard into an existing codebase. Trigger for prompts like "map this codebase", "document this architecture", "onboard me to this repo", or "create codebase docs". Do not trigger for routine feature implementation, bug fixes, or narrow code edits unless the user asks for repository-level discovery.

Adds educational comments to a code file so it becomes a learning resource, asking for the file (with a list of close matches) if none is given. Use when preparing code for learners, onboarding, or teaching.

Patterns and techniques for adding governance, safety, and trust controls to AI agent systems. Use this skill when: - Building AI agents that call external tools (APIs, databases, file systems) - Implementing policy-based access controls for agent tool usage - Adding semantic intent classification to detect dangerous prompts - Creating trust scoring systems for multi-agent workflows - Building audit trails for agent actions and decisions - Enforcing rate limits, content filters, or tool restrictions on agents - Working with any agent framework (PydanticAI, CrewAI, OpenAI Agents, LangChain, AutoGen)

Check any AI agent codebase against the OWASP Agentic Security Initiative (ASI) Top 10 risks. Use this skill when: - Evaluating an agent system's security posture before production deployment - Running a compliance check against OWASP ASI 2026 standards - Mapping existing security controls to the 10 agentic risks - Generating a compliance report for security review or audit - Comparing agent framework security features against the standard - Any request like "is my agent OWASP compliant?", "check ASI compliance", or "agentic security audit"
