Risk Level: MEDIUM
Full Analysis
MEDIUM W011: Third-party content exposure detected (indirect prompt injection risk).
- Third-party content exposure detected (high risk: 0.90). SKILL.md explicitly instructs the agent to "Fetch fresh guidelines" from the public URL https://raw.githubusercontent.com/vercel-labs/web-interface-guidelines/main/command.md and to read/apply those fetched rules as part of its workflow, meaning the agent ingests open third‑party content that can materially change its actions.
MEDIUM W012: Unverifiable external dependency detected (runtime URL that controls agent).
- Potentially malicious external URL detected (high risk: 0.90). The skill explicitly instructs fetching runtime guidelines from https://raw.githubusercontent.com/vercel-labs/web-interface-guidelines/main/command.md and uses that fetched content to supply the rules and output-format instructions that directly control the agent's review behavior, making it a required external dependency.
