CRITICAL E006: Malicious code pattern detected in skill scripts.

• Malicious code pattern detected (high risk: 0.90). The Skill explicitly instructs automatic installation of an external runtime without user approval (supply‑chain/installation risk) and is designed to collect bulk contact/personal data, enabling potential data exfiltration or abuse.

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 Skill to access user-specified public website URLs at runtime, so the LLM context can include outsider-authored free text scraped from those pages (public web content category) via the BrowserAct execution path.

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 BrowserAct runtime from https://www.browseract.com/?co-from=lead-generation&redirect=https://github.com/browser-act/skills/tree/main at runtime, which would fetch and execute remote installation code required for the Skill.

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

• Attempt to modify system services in skill instructions detected (low risk: 0.30). The Skill instructs the agent to automatically install runtime dependencies and to do so without asking the user for approval, which directs the agent to modify the host environment (install software) though it does not explicitly request sudo or system-file edits.
