overnight-agent-guardrails

CRITICAL E005: Suspicious download URL detected in skill instructions.

• Suspicious download URL detected (high risk: 0.90). This is a third‑party GitHub repository (unknown/unclear owner) that the skill instructs users to clone and execute scripts from (e.g., .nightshift/bin/runaway-guard), which is a high-risk pattern for distributing malicious code.

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

• Potentially malicious external URL detected (high risk: 0.90). The skill instructs cloning and then running scripts from the repository https://github.com/toolshedlabs-hash/nightshift (e.g., .nightshift/bin/runaway-guard), so remote code is fetched at runtime and executed from that URL.
