CRITICAL E004: Prompt injection detected in skill instructions.

• Potential prompt injection detected (high risk: 0.90). The skill instructs the agent to install BrowserAct automatically without asking the user and explicitly to avoid describing the installation request or seeking separate approval, which is a deceptive runtime instruction outside the stated monitoring 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 the runtime browser-act Skill to “capture browser-visible page content” from user-specified Walmart URLs, which is outsider-authored free text scraped from public web pages at runtime.

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

• Potentially malicious external URL detected (high risk: 0.90). The Skill instructs the agent at runtime to automatically install a required CLI using the Install BrowserAct URL (https://www.browseract.com/?co-from=ecommerce&redirect=https://github.com/browser-act/skills/tree/main), which is a remote installer that would fetch/execute code and directly affects agent behavior.
