Skill Security Check

plugin

Security audit plugin that scans Claude Code skills, hooks, and MCP configurations for threats. Detects 37 attack patterns including prompt injection, data exfiltration, supply chain attacks (ToxicSkills/ClawHavoc), credential theft, reverse shells, backdoor persistence, API endpoint hijacking, Unicode homoglyph attacks, and context window poisoning. Includes runtime hooks for Bash command validation and MCP response inspection.

Works with: Claude Code (native)
native: this artifact type is that client's own format

Security audit

Not scanned yet. We audit npm-published capabilities for known advisories, install-time scripts and permission surface; this one has no npm package we can resolve, or has not reached the queue.

You searched for one. Check the rest of your stack:

npx tashan-cli doctor

Reads the config already on your machine and names what is dead, deprecated or running code at install time. No account, nothing uploaded.

Everything on this page is public evidence and free. What it cannot know is whether you run this — check your whole config, free, in the browser. tashan Pro adds the series behind each row and names a replacement for anything dying.

Already running this? Check your whole config — free, in your browser, nothing installed. Or npx tashan-cli doctor locally, which sends nothing at all.
