The Agent Skills Directory

[DYNAMIC_EXECUTION]: The script scripts/fill_fillable_fields.py performs a runtime monkeypatch of the pypdf library. It replaces the DictionaryObject.get_inherited method with a wrapper to resolve a bug in how selection list fields are handled in version 5.7.0 of the library. While functionally justified for the skill's operation, runtime modification of third-party libraries is a notable dynamic execution pattern.
[INDIRECT_PROMPT_INJECTION]: The skill processes untrusted PDF documents and images, creating a surface for indirect prompt injection. 1. Ingestion points: External data enters through pypdf, pdfplumber, pypdfium2, and OCR tools like pytesseract. 2. Boundary markers: No explicit delimiters or guardrails are defined in the instructions to wrap extracted text content. 3. Capability inventory: The skill performs file system operations (reading and writing PDFs, images, and JSON) and executes helper scripts. 4. Sanitization: Extracted text is not sanitized or filtered for potential malicious instructions before processing.
[COMMAND_EXECUTION]: The instructions and scripts guide the agent to use external command-line tools like qpdf, pdftotext, pdftk, and pdfimages for various document processing tasks.
