How it works

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

1. Vet at install

A tiny meta-skill sits in your agent. Every skill or MCP server install is checked before it runs. Warn, block, or allow by policy.

2. Detonate in a honeypot

Every skill runs inside a sandboxed agent with fake credentials, decoy tools, and a watched MEMORY.md. The verdict is a behavior trace, not a guess.

3. Watch for drift

53% of adopted skills are never updated while their upstreams change. We diff every release, re-detonate, and alert your team when a verdict moves.
