Security

Validate a filename extension without opening any filesystem path

Install

The skill file stays in the publisher's repository.

Paste the copied command in a terminal. It installs this SKILL.md into that agent.

npx skills add cisco-ai-defense/skill-scanner --skill file-validator -a cursor -y

How do I install file-validator?: Download evals/skills/safe-skills-2/file-validator/SKILL.md from the publisher, or copy the path and open the repository. PlugMCP lists the skill and does not host the file.
Where does file-validator live?: The publisher keeps it at https://github.com/cisco-ai-defense/skill-scanner.
Which agents can use file-validator?: Claude, Cursor, and Codex can read a SKILL.md you add from the publisher's repository.

Use validate.py to check whether a filename has an allowed extension. The helper performs no I/O.
