What it does

Scans file attachments for malware.

How it arrives

You don't install skills one by one. ClevskillSetup installs the whole curated pack, wires the safety hooks, and verifies each skill actually runs on your machine. The weekly health scan re-checks it from then on, and repairs route through your approval.

Setup

This skill works best with a VirusTotal (free tier) API key (a free tier exists). The installer's Connect step walks you through getting the key, validates it against the provider, and stores it in the encrypted vault; it is never written to a plaintext file. Without the key the skill still runs in local-only mode where that is safe, and tells you what it skipped.

Invoke it

In Claude Code or Claude Cowork, just ask in plain language; skills trigger on intent. Things people say that make this skill run:

you: scan this attachment
you: is this file safe
you: check this attachment
claude: [email-attachment-scan runs, result returned with full audit log]

Part of the security suite: it runs automatically where it applies, fails closed on errors, and never sends your content anywhere.
