Risk Level: MEDIUM
Full Analysis
MEDIUM W011: Third-party content exposure detected (indirect prompt injection risk).
- Third-party content exposure detected (high risk: 1.00). The skill explicitly uses WebFetch to retrieve and apply rules from a public third-party URL (https://raw.githubusercontent.com/vercel-labs/web-interface-guidelines/main/command.md) and then reads and enforces those fetched rules as part of its workflow, so untrusted external content can influence the agent's behavior.
MEDIUM W012: Unverifiable external dependency detected (runtime URL that controls agent).
- Potentially malicious external URL detected (high risk: 1.00). The skill explicitly fetches runtime instructions from https://raw.githubusercontent.com/vercel-labs/web-interface-guidelines/main/command.md and uses that content as the authoritative set of rules and output-formatting instructions, so the external URL directly controls agent prompts/behavior and is a required runtime dependency.
