What would fix thisWatchDispute verdict

Is buildkite@r2 safe to install?

KillerSkills ran it in the KillerSkills honeypot sandbox (1 scenario) on 2026-10-27 and scored it 65/100 (Caution). It is not known to be malicious, but it has behaviour or code a security policy should decide on before install. Notable findings: Fake instruction boundary tag; Pipe-to-shell pattern; Fake instruction boundary tag. Summary: no network, touches nothing outside the project, writes no memory.
