The Agent Skills Directory

[DYNAMIC_EXECUTION]: The script scripts/fill_fillable_fields.py performs a monkeypatch at runtime, replacing the DictionaryObject.get_inherited method in the pypdf library with a custom implementation (monkeypatch_pydpf_method). This is documented as a workaround for a specific bug in pypdf version 5.7.0 that causes crashes when processing choice list fields.
[INDIRECT_PROMPT_INJECTION]: The skill's primary function is to process untrusted PDF documents, which presents a surface for indirect prompt injection if malicious content within a PDF influences the agent's logic.
Ingestion points: Untrusted data enters via PDF files read by pypdf and pdfplumber (as seen in scripts/extract_form_field_info.py and SKILL.md) and configuration files loaded via json.load().
Boundary markers: The skill documentation in forms.md explicitly mandates a multi-step verification process, requiring the agent to perform visual analysis of images and run automated checks (scripts/check_bounding_boxes.py) before completing tasks.
Capability inventory: The skill possesses the capability to write PDF files (writer.write), generate images (image.save), and execute command-line utilities such as qpdf and pdftotext.
Sanitization: The scripts/fill_fillable_fields.py utility includes a validation_error_for_field_value function that strictly validates input values against the PDF's schema (e.g., checking valid options for checkboxes and radio groups) before writing data.
