The Agent Skills Directory

[EXTERNAL_DOWNLOADS]: The skill provides instructions to download and install the open-library-pp-cli binary using npx from the @mvanhorn/printing-press-library registry and go install from the github.com/mvanhorn/printing-press-library repository. These resources are associated with the skill's author context.
[COMMAND_EXECUTION]: The skill is designed to execute shell commands using the open-library-pp-cli binary to search for books, lookup ISBNs, and fetch author bibliographies.
[PROMPT_INJECTION]: The skill processes untrusted metadata from the Open Library API which could serve as a vector for indirect prompt injection.
Ingestion points: External book, author, and edition metadata returned by the Open Library API (SKILL.md).
Boundary markers: Absent. The skill does not define specific delimiters for the API output.
Capability inventory: The agent is permitted to use the Read Bash tool to execute CLI commands.
Sanitization: None. There are no instructions to sanitize or escape the content retrieved from the external API before it is processed by the agent.
