The Agent Skills Directory

[EXTERNAL_DOWNLOADS]: Fetches the pdf2zine shell script from the author's GitHub repository (github.com/eins78/pdf2zine). It also references an external source for building bookletimposer from source (git.codecoop.org/kjo/bookletimposer).
[COMMAND_EXECUTION]: Executes shell commands to install and run the PDF manipulation tool, including chmod +x to grant execution permissions to the downloaded script.
[PRIVILEGE_ESCALATION]: Includes instructions to use sudo apt install for installing the bookletimposer dependency on Debian-based systems.
[INDIRECT_PROMPT_INJECTION]: The skill processes untrusted PDF files using command-line tools, creating a surface where malicious content in a PDF could potentially exploit the underlying parser.
Ingestion points: Processes PDF files provided as input to the pdf2zine or bookletimposer commands (mentioned in SKILL.md and references/bookletimposer-native.md).
Boundary markers: Absent; there are no instructions to the agent to ignore embedded content or use specific delimiters.
Capability inventory: Includes file read/write access and CLI tool execution (qpdf, bookletimposer, pdf2zine) as described in SKILL.md and references/bookletimposer-native.md.
Sanitization: Absent; the skill does not specify any validation or sanitization of the PDF content prior to processing.
