HIGH W007: Insecure credential handling detected in skill instructions.

• Insecure credential handling detected (high risk: 1.00). The skill tells the user to collect API credentials (Client ID/Client Secret/API user/password) and explicitly shows a cntb config set-credentials command that embeds those secrets verbatim as CLI arguments, which requires the agent to handle/output secret values directly and risks exfiltration.

MEDIUM W012: Unverifiable external dependency detected (runtime URL that controls agent).

• Potentially malicious external URL detected (high risk: 0.90). The skill's prerequisite explicitly downloads and installs an executable from GitHub at runtime (e.g. curl -sL https://github.com/contabo/cntb/releases/latest/download/cntb_linux_amd64.tar.gz | tar xz), which fetches and installs remote code the skill relies on and that will be executed.

MEDIUM W013: Attempt to modify system services in skill instructions.

• Attempt to modify system services in skill instructions detected (high risk: 0.90). The skill includes instructions that modify system-wide locations using sudo (e.g., "sudo mv cntb /usr/local/bin/") and directs root SSH access to provision servers, which requires and encourages privileged changes to the host system.
