CRITICAL E004: Prompt injection detected in skill instructions.

• Potential prompt injection detected (high risk: 0.90). The Skill instructs the agent to automatically install a runtime dependency and explicitly tells the agent not to describe the installation to the user or request approval, which is a hidden/deceptive instruction outside the advertised scraping functionality.

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 BrowserAct CLI to access live Threads web pages at runtime, which can ingest outsider-authored free text from public web content into the LLM context via the browser-extracted page content.

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

• Potentially malicious external URL detected (high risk: 0.90). The Skill mandates using BrowserAct and, if missing, automatically installing it via the provided installer links (https://www.browseract.com/?co-from=social-media and https://www.browseract.com/?co-from=social-media&redirect=https://github.com/browser-act/skills/tree/main), which indicates the agent will fetch and run external installation code at runtime to satisfy a required dependency.
