HIGH W007: Insecure credential handling detected in skill instructions.

• Insecure credential handling detected (high risk: 0.80). The skill mandates generating secrets on the target box (good) but also requires handing the generated N8N_ENCRYPTION_KEY to the user (and could involve printing or relaying that secret), which forces the agent to handle/output a secret verbatim and creates an exfiltration risk.

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

• Potentially malicious external URL detected (high risk: 0.80). The skill explicitly instructs installing Docker via Docker's official installation script (https://get.docker.com), which would be fetched and executed on the target box at runtime and thus runs remote code.

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

• Attempt to modify system services in skill instructions detected (high risk: 1.00). This skill explicitly instructs the agent to perform system-level changes (install Docker as root, create directories under /opt, write system files, modify firewall/ufw, run docker compose and manage certificates) that require sudo/root and alter the machine's state.
