The Agent Skills Directory

[EXTERNAL_DOWNLOADS]: The skill fetches real-time UV monitoring data from the Australian Radiation Protection and Nuclear Safety Agency (ARPANSA) via their public XML feed at https://uvdata.arpansa.gov.au/xml/uvvalues.xml. This is a trusted government source for environmental safety information.
[COMMAND_EXECUTION]: A dynamic context injection in SKILL.md executes a shell command (command -v uv) at load time to verify that the required uv tool is installed in the environment. This is a benign diagnostic check used to ensure the skill can run.
[PROMPT_INJECTION]: The skill processes external data from the ARPANSA feed, which theoretically represents an indirect prompt injection surface.
Ingestion points: Data is fetched from an external government XML feed and processed in scripts/uv_sun.py.
Boundary markers: The SKILL.md file defines specific JSON output formats and presentation rules, which help the agent distinguish between data and instructions.
Capability inventory: The skill can execute shell commands via uv run, perform network requests to the ARPANSA domain, and write to a local cache directory in the user's home folder.
Sanitization: The script parses the XML structure and validates UV index values by casting them to floating-point numbers, though general text fields from the feed are not explicitly sanitized against secondary instructions.
