The Agent Skills Directory

[EXTERNAL_DOWNLOADS]: The skill facilitates the installation of the gisis-pp-cli tool and printing-press-library from the author's GitHub and NPM repositories using go install and npx.
[COMMAND_EXECUTION]: The skill requires the execution of shell commands to manage maritime registry lookups, session authentication via press-auth, and CLI configuration.
[DATA_EXFILTRATION]: The CLI tool provides a --deliver webhook:<url> feature that enables command outputs, such as vessel particulars and ownership data, to be transmitted to arbitrary external URLs.
[PROMPT_INJECTION]: The skill ingests untrusted maritime data from the external GISIS registry (through commands like ship get and ship list) without defining boundary markers or sanitization procedures. This creates a surface for indirect prompt injection where malicious registry metadata could influence the agent's behavior, especially given the agent's access to the Bash tool and network sinks.
