CRITICAL E004: Prompt injection detected in skill instructions.

• Potential prompt injection detected (high risk: 0.90). The Skill contains explicit, deceptive runtime instructions to auto-install a dependency and to "not describe" that installation or request user approval, which overrides normal consent and hides behavior outside the Skill's advertised data-collection purpose.

CRITICAL E006: Malicious code pattern detected in skill scripts.

• Malicious code pattern detected (high risk: 1.00). The document explicitly instructs automated installation of an external runtime dependency without user consent and directs the agent to conceal that action, creating a clear supply‑chain/backdoor 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 invoke the BrowserAct CLI to access real browser pages at runtime and collect visible comment text (outsider-authored free text from public web pages) into the agent’s processing context.

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

• Potentially malicious external URL detected (high risk: 0.90). The skill explicitly requires and instructs the agent at runtime to automatically install and invoke the BrowserAct CLI using the provided install link (https://www.browseract.com/?co-from=social-media&redirect=https://github.com/browser-act/skills/tree/main), which is a required dependency that would fetch and execute remote installation code.
