harness-prepare

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

• Potentially malicious external URL detected (high risk: 0.90). The skill instructs running npx to fetch and execute remote package code at runtime (e.g., "npx @nextstage-brasil/harness --preset delivery --yes" and "npx @nextstage-brasil/harness sync"), which causes remote code execution from the npm registry.
