2 findings — 2 medium severity. This skill can be installed but you should review these findings before use.
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: 0.90). The SKILL.md workflow and Step 1 explicitly require using WebFetch to retrieve and parse the public GitHub raw URL https://raw.githubusercontent.com/vercel-labs/web-interface-guidelines/main/command.md and then apply those fetched rules to drive review decisions, so arbitrary content at that third-party URL could materially influence the agent's actions.
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: 1.00). The skill requires fetching live rules from https://raw.githubusercontent.com/vercel-labs/web-interface-guidelines/main/command.md at runtime, and those fetched guidelines directly control the agent's instructions/output format and are a required dependency for each review.
