[COMMAND_EXECUTION]: The documentation provides examples for using established command-line tools for PDF manipulation, including qpdf, pdftotext, pdftk, and pdfimages.
[PROMPT_INJECTION]: The skill is designed to process external PDF files, which is an intended functionality that introduces an indirect prompt injection surface.
Ingestion points: Untrusted PDF documents are processed by scripts such as scripts/extract_form_field_info.py and scripts/fill_fillable_fields.py.
Boundary markers: The skill does not currently implement explicit boundary markers for the data extracted from PDF files.
Capability inventory: The skill can execute shell commands and perform file system writes as part of its document processing workflows.
Sanitization: The skill processes the structural components and text of PDF files without explicit sanitization of the embedded content.
[SAFE]: The script scripts/fill_fillable_fields.py utilizes a runtime monkeypatch of the pypdf library to fix a specific bug in selection list processing, ensuring correct form field functionality.
