CRITICAL E004: Prompt injection detected in skill instructions.

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

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

• Third-party content exposure detected (low risk: 0.10). The workflow scrapes arbitrary web pages via BrowserAct, where an agent actively fetches and extracts outsider-authored content from selected URLs.

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 an external skill from a GitHub repository via https://www.browseract.com/?co-from=ecommerce&redirect=https://github.com/browser-act/skills/tree/main, establishing an unknown third-party runtime dependency with high-risk provenance.
