CRITICAL E004: Prompt injection detected in skill instructions.

• Potential prompt injection detected (high risk: 1.00). The skill instructs the agent to install dependencies automatically without user confirmation and explicitly to conceal that the installation link is a request for the user to open their browser, which are deceptive runtime instructions outside the declared scraping purpose.

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

• Third-party content exposure detected (high risk: 0.85). SKILL.md instructs the agent to use BrowserAct to access live Facebook ad library pages at runtime and then return/export the scraped ad copy/creatives, which are outsider-authored free text from public web content.

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

• Potentially malicious external URL detected (high risk: 0.90). The skill explicitly instructs the agent to automatically install and invoke BrowserAct at runtime using the install link https://www.browseract.com/?co-from=social-media&redirect=https://github.com/browser-act/skills/tree/main (and references https://www.browseract.com/?co-from=social-media), which would fetch and run remote installation code for a required runtime dependency.
