The Agent Skills Directory

[EXTERNAL_DOWNLOADS]: The skill instructions and execution commands utilize the uv tool to dynamically fetch the pymupdf library. PyMuPDF is a well-known, reputable open-source library for PDF manipulation and analysis.
[PROMPT_INJECTION]: The skill processes content from external, untrusted PDF files including text, metadata, and visual renders. This constitutes an indirect prompt injection surface where instructions embedded in a PDF could attempt to influence agent behavior.
Ingestion points: Content is read into the agent context via pdf_info.py, pdf_extract.py, and pdf_search.py.
Boundary markers: The scripts do not wrap extracted text in specific delimiters or safety headers before outputting to the agent.
Capability inventory: The skill has the ability to read files from the filesystem and write rendered images to the system's temporary directory (/tmp).
Sanitization: No sanitization or filtering of the PDF content is performed prior to display.
