The Agent Skills Directory

[EXTERNAL_DOWNLOADS]: The skill downloads research papers and metadata from established academic and government repositories including NCBI (PMC), Europe PMC, Unpaywall, OpenAlex, and Crossref. These are well-known, reputable sources in the scientific community.
[COMMAND_EXECUTION]: The provided Python scripts are intended for command-line execution by the agent. fetch_oa.py uses only Python standard libraries to perform HTTP requests and file operations. pdf_to_md.py uses the well-known pymupdf4llm library for PDF processing.
[DATA_EXPOSURE_EXFILTRATION]: The skill requires a contact email to comply with the 'polite' usage policies of academic APIs (Unpaywall/Crossref). This is standard practice for research tools and is transparently requested from the user.
[INDIRECT_PROMPT_INJECTION]: The skill has a data ingestion surface as it processes external DOI lists and PDF content.
Ingestion points: fetch_oa.py reads DOI lists; pdf_to_md.py processes downloaded PDF files.
Boundary markers: Not explicitly defined in the processing scripts.
Capability inventory: The skill possesses network read access and local file write access.
Sanitization: PDF conversion extracts text layer data; DOI inputs are validated via regex patterns.
