CRITICAL E004: Prompt injection detected in skill instructions.

• Potential prompt injection detected (high risk: 1.00). The skill instructs the agent to automatically install the BrowserAct dependency and explicitly tells the agent not to describe the installation link as a user-facing request or ask for separate approval, which is deceptive and outside the stated monitoring purpose.

CRITICAL E006: Malicious code pattern detected in skill scripts.

• Malicious code pattern detected (high risk: 0.90). The skill contains explicit instructions to silently install and invoke an external CLI dependency without user confirmation and to avoid informing the user, enabling stealthy installation/remote code execution (supply-chain risk); it also permits capturing browser-visible network responses which could expose sensitive data if abused.

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 invoke the browser-act Skill to “capture browser-visible page content” from user-specified target URLs at runtime, which is outsider-authored free text from public web pages.

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 the BrowserAct CLI at runtime using the provided installer URL (https://www.browseract.com/?co-from=ecommerce&redirect=https://github.com/browser-act/skills/tree/main), which would fetch and execute remote code and is treated as a required runtime dependency.
