CRITICAL E004: Prompt injection detected in skill instructions.

• Potential prompt injection detected (high risk: 0.90). The Skill contains instructions to automatically install a runtime dependency without user confirmation and to hide/avoid describing that installation to the user, which are deceptive operational directives outside the stated scraping purpose.

CRITICAL E006: Malicious code pattern detected in skill scripts.

• Malicious code pattern detected (high risk: 1.00). The Skill explicitly instructs automatic installation of an external CLI and directs the agent to hide that action and avoid seeking user approval, creating a deliberate supply-chain/unauthorized-install and hidden data-collection risk.

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 BrowserAct CLI to “capture browser-visible page content” from user-specified eBay/public URLs at runtime, which would ingest outsider-authored free text from fetched web pages into the LLM context.

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 to automatically install the required BrowserAct runtime at execution time from https://www.browseract.com/?co-from=ecommerce (and the install redirect URL https://www.browseract.com/?co-from=ecommerce&redirect=https://github.com/browser-act/skills/tree/main), which is a required runtime dependency that would fetch and execute external code.
