How it works

Static scans read the code. We watch what it does.

1. Vet at install

A tiny hook sits in your agent. Every skill or MCP server install is checked before it runs; a vet-skills.lock pins the exact bytes that were vetted. Warn, block, or allow by policy.

Install the CLI →

2. Detonate in a honeypot

Every release runs in a sandbox with decoy credentials, a watched MEMORY.md and a recording proxy, usually within an hour of being published. The verdict is a behavior trace, not a guess, and the method is public.

3. Verify, don't trust us

Every verdict is a signed attestation you can check offline against our published key. vet-skills verify does it in one command; CI can refuse anything whose bytes changed since review.

4. Watch what it does next

We diff every release and re-detonate. The hook compares what a skill does in your real sessions with what the sandbox saw. Anything new is a drift alert, and anyone can watch a skill for changes.

Verdicts, as they land.

Every public skill and MCP server on skills.sh, ClawHub, the Claude Code plugin marketplaces, npm, PyPI, the Docker MCP Catalog and the official MCP Registry, continuously re-scanned. Every verdict has a permanent page.
