CRITICAL E004: Prompt injection detected in skill instructions.

• Potential prompt injection detected (high risk: 0.90). The Skill contains explicit instructions to auto-install runtime dependencies without asking the user and to hide/avoid describing that installation, which is deceptive and outside the advertised scraping task.

CRITICAL E006: Malicious code pattern detected in skill scripts.

• Malicious code pattern detected (high risk: 1.00). High-risk: the skill explicitly instructs automatically installing and executing an external CLI without user consent and to conceal the installation request, enabling supply-chain/backdoor remote code execution and unauthorized actions.

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 “access real browser pages” and “capture browser-visible page content” from user-specified eBay/public URLs, which can include outsider-authored free text from fetched 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 at runtime to install and invoke BrowserAct using the install link (https://www.browseract.com/?co-from=ecommerce&redirect=https://github.com/browser-act/skills/tree/main), which would fetch and install remote code that the Skill treats as a required runtime dependency and then control execution.
