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

What this means

The skill exposes the agent to untrusted, user-generated content from public third-party sources, creating a risk of indirect prompt injection. This includes browsing arbitrary URLs, reading social media posts or forum comments, and analyzing content from unknown websites.

Why it was flagged

Third-party content exposure detected (high risk: 1.00). The SKILL.md explicitly tells the agent to "Fetch the latest guidelines" from the public URL https://raw.githubusercontent.com/vercel-labs/web-interface-guidelines/main/command.md (via WebFetch) and to apply those fetched rules/instructions to drive its review/output, which means untrusted third‑party content can directly influence the agent's behavior.

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

What this means

The skill fetches instructions or code from an external URL at runtime, and the fetched content directly controls the agent’s prompts or executes code. This dynamic dependency allows the external source to modify the agent’s behavior without any changes to the skill itself.

Why it was flagged

Potentially malicious external URL detected (high risk: 0.90). The skill instructs the agent to fetch and use the remote guidelines at runtime (https://raw.githubusercontent.com/vercel-labs/web-interface-guidelines/main/command.md), and that fetched content directly supplies the rules and output-format instructions that will control the agent's behavior.
