tessl review fix ./plugins/vercel/skills/vercel-sandbox/SKILL.mdW011: 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
The agent navigates to arbitrary user-supplied or web-scraped URLs (`url: string`) during browser automation workflows, making any ingested web content a low-risk source of untrusted free text.
