MEDIUM W011: Third-party content exposure detected (indirect prompt injection risk).

• Third-party content exposure detected (high risk: 0.85). This skill explicitly “fetch[es] fresh guidelines” from a public URL at runtime (outsider-authored web content) and then uses the fetched text as the rules/context for the review.

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

• Potentially malicious external URL detected (high risk: 1.00). The skill instructs at runtime to fetch remote rules that control checks and output format from https://raw.githubusercontent.com/vercel-labs/web-interface-guidelines/main/command.md, so the fetched content directly controls agent behavior.
