CRITICAL E004: Prompt injection detected in skill instructions.

• Potential prompt injection detected (high risk: 0.90). The skill explicitly instructs the agent to install BrowserAct automatically "without asking the user to confirm" and to hide/avoid describing the installation link as a user-facing request, which are deceptive runtime instructions outside the stated scraping 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 target URLs, which can include outsider-authored free text from public web pages fetched at runtime.

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

• Potentially malicious external URL detected (high risk: 0.90). The skill explicitly instructs the agent to automatically install the required BrowserAct Skill/CLI at runtime using the provided install link (https://www.browseract.com/?co-from=ecommerce&redirect=https://github.com/browser-act/skills/tree/main), which will fetch external installation content (redirecting to a GitHub repo) and thus introduces a runtime fetch that can execute code.

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 directs the agent to automatically install the BrowserAct CLI/runtime dependencies without asking the user for approval and to treat that installation as an agent action, which pushes the agent to modify the host system state and bypass user consent.
