The Agent Skills Directory

[EXTERNAL_DOWNLOADS]: The skill provides instructions to install the usgs-earthquakes-pp-cli tool via npx from the @mvanhorn/printing-press-library npm package and via go install from the github.com/mvanhorn/printing-press-library repository. Both resources are hosted on well-known services and belong to the skill's identified vendor.
[COMMAND_EXECUTION]: The watch command includes a --notify parameter designed to execute shell commands as hooks when new events are detected. This is a documented feature for system integration.
[DATA_EXFILTRATION]: The CLI provides a --deliver webhook:<url> capability, allowing earthquake data to be sent to external HTTP endpoints for reporting or automation purposes.
[PROMPT_INJECTION]: The skill processes external USGS GeoJSON feeds. While this represents a surface for indirect prompt injection (Category 8), the capabilities are limited to the tool's earthquake monitoring functions and do not bypass agent safety constraints.
