CRITICAL E004: Prompt injection detected in skill instructions.

• Potential prompt injection detected (medium risk: 0.30). The skill contains instructions to automatically install a runtime dependency without user confirmation, which weakens user control over software execution boundaries.

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

• Third-party content exposure detected (low risk: 0.10). The skill scrapes public web pages and search results via BrowserAct, exposing the agent to outsider-authored product listings and text at low risk.

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

• Potentially malicious external URL detected (high risk: 0.70). The skill instructs the agent to automatically download and install a runtime dependency from an arbitrary third-party GitHub repository (https://github.com/browser-act/skills/tree/main), introducing an unverified remote dependency with weak provenance.
