Coverage

Not started: dependency install failed; the server itself was not observed.
Tested
install scripts, with decoy credentials in place · second launch with the clock 45 days ahead · the dependency install step · every file read, file written and host contacted by what ran
Not tested
server startup · the tool list · tool behavior

What this means for the label: Verified here covers what ran. The server's tools were not exercised with a real credential, so nothing about their behavior is asserted; the credential summary below says what to do with that.

Where it talks to
codenib.ai (its own)Also openrouter.ai — not the publisher's domain; check what for before connecting.
What the honeypot saw
no credential files read · no network
What we could not test
server startup · the tool list · tool behavior

Connect it with a scoped credential, under the guard, and read the third-party hosts first. The code names openrouter.ai as well as its own vendor. The guard injects CODENIB_DEMO_API_KEY, CODENIB_DEMO_WIKI_API_KEY, CODENIB_EMBEDDING_API_KEY, CODENIB_EMBEDDING_API_KEY_ENV, CODENIB_WIKI_MEDIA_API_KEY, CODENIB_WIKI_VISUAL_FACTS_API_KEY, OPENROUTER_API_KEY only into requests to codenib.ai (and its subdomains) and refuses the rest.

$vet-skills run --secrets CODENIB_DEMO_API_KEY=codenib.ai,CODENIB_DEMO_WIKI_API_KEY=codenib.ai,CODENIB_EMBEDDING_API_KEY=codenib.ai,CODENIB_EMBEDDING_API_KEY_ENV=codenib.ai,CODENIB_WIKI_MEDIA_API_KEY=codenib.ai,CODENIB_WIKI_VISUAL_FACTS_API_KEY=codenib.ai,OPENROUTER_API_KEY=codenib.ai -- uvx codenib

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 (3 scenarios; not started: dependency install failed; the server itself was not observed) on 2026-11-15 and scored it 91/100 (Verified). In what ran, nothing we could detect went wrong: no undeclared network egress, no credential reads, no persistent instruction writes. What it does with a real credential was not observed; the static findings and the publisher carry the rest of the score. Summary: no network, touches nothing outside the project, writes no memory.
