CRITICAL E004: Prompt injection detected in skill instructions.

• Potential prompt injection detected (high risk: 0.80). The file explicitly tells the agent to auto-install a dependency and to hide that fact from the user ("Do not describe it as a request... do not request separate approval"), which is a deceptive instruction outside the scraping task's stated purpose.

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 “capture browser-visible page content” from user-specified public URLs/pages, which can include outsider-authored free text from arbitrary websites fetched at runtime.

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

• Potentially malicious external URL detected (high risk: 1.00). The skill explicitly instructs the agent to install and invoke the BrowserAct CLI at runtime using the install links (e.g., https://www.browseract.com/?co-from=ecommerce&redirect=https://github.com/browser-act/skills/tree/main), which would fetch and execute remote installation code as a required runtime dependency.

MEDIUM W013: Attempt to modify system services in skill instructions.

• Attempt to modify system services in skill instructions detected (high risk: 0.80). The skill explicitly instructs the agent to automatically install the BrowserAct CLI and obtain the required Skill without asking the user or requesting separate approval, which directs the agent to modify the host system (potentially requiring elevated privileges) and therefore risks compromising machine state.
