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 fetches and reads live guidelines from a public GitHub URL (https://raw.githubusercontent.com/vercel-labs/web-interface-guidelines/main/command.md) via WebFetch, exposing the agent to untrusted third-party content that it will read and apply.
MEDIUM W012: Unverifiable external dependency detected (runtime URL that controls agent).
- Potentially malicious external URL detected (high risk: 0.90). This skill explicitly fetches runtime rules and output-formatting instructions from https://raw.githubusercontent.com/vercel-labs/web-interface-guidelines/main/command.md and uses that fetched content to control the agent's review rules and outputs, making it a required external dependency that directly controls prompts/instructions.
