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 with a scoped credential, under the guard, and read the third-party hosts first. The code names ellipsis.dev, mem0.ai, getzep.com, supermemory.ai, honcho.dev, vectorize.io, letta.com as well as its own vendor. The guard injects ELLIPSIS_API_TOKEN, ELLIPSIS_SESSION_TOKEN, HINDSIGHT_API_KEY, HONCHO_API_KEY, LETTA_API_KEY, MEM0_API_KEY, SLASHML_API_KEY, SUPERMEMORY_API_KEY, ZEP_API_KEY only into requests to slashml.ai (and its subdomains) and refuses the rest.

$vet-skills run --secrets ELLIPSIS_API_TOKEN=slashml.ai,ELLIPSIS_SESSION_TOKEN=slashml.ai,HINDSIGHT_API_KEY=slashml.ai,HONCHO_API_KEY=slashml.ai,LETTA_API_KEY=slashml.ai,MEM0_API_KEY=slashml.ai,SLASHML_API_KEY=slashml.ai,SUPERMEMORY_API_KEY=slashml.ai,ZEP_API_KEY=slashml.ai -- npx -y @slashml/mcp

Never paste a credential into a chat, a ticket or a report, including ours. How the guard holds it.

KillerSkills ran it in the KillerSkills honeypot sandbox (2 scenarios) on 2026-11-12 and scored it 83/100 (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.
