What the honeypot saw
no credential files read · no network
What we could not test
what the tools do when called with real credentials

Connect it under the guard; read the third-party hosts first. The code names lemonsqueezy.com, polar.sh, mcp-schnittstellen.de, aiim.org, purl.org as well as its own vendor. The guard pins the network to the hosts the honeypot saw.

KillerSkills ran it in the KillerSkills honeypot sandbox (2 scenarios) on 2026-11-11 and scored it 82/100 (Verified). It did what it claims and nothing else we could detect: no undeclared network egress, no credential reads, no persistent instruction writes. Summary: no network, touches nothing outside the project, writes no memory.
