What would fix this Watch Dispute verdict

Coverage

Static only; nothing was run yet.

The label rests on the code, the instruction files and the publisher. The honeypot run replaces this verdict when it completes.

Before you give it your token

It will ask for: APIC_PASSWORDMCP_ALLOW_NO_AUTHMCP_API_KEYSConfiguration, not credentials: APIC_HOST, APIC_USER, APIC_VERIFY_SSL, MCP_HOST, MCP_PORT, NIWASHI_MCP_ENV_FILE
Where it talks to: no vendor host named in the code
What the honeypot saw: nothing has run yet
What we could not test: everything: the server has not run yet

Run it before you trust it. Nothing has run yet: the code was read, the server was not. `vet-skills try` runs this exact version in the honeypot in about a minute.

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

KillerSkills analysed it statically (a sandbox run is pending) on 2026-11-13 and scored it 58/100 (Caution). It is not known to be malicious, but it has behaviour or code a security policy should decide on before install. Notable findings: Access to sensitive file paths; Access to sensitive file paths; Access to sensitive file paths. Summary: static analysis only — behavior not yet observed.
