CRITICAL E004: Prompt injection detected in skill instructions.

• Potential prompt injection detected (high risk: 0.90). The Skill contains deceptive installation instructions that explicitly tell the agent to install a dependency automatically and to avoid asking the user or describing the action as a browser request, which instructs the agent to hide or bypass user consent 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 BrowserAct to access live public Reddit pages at runtime and extract fields including “Body text” (outsider-authored free text from public web content), which would be ingested into the LLM context as scraped 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 and, if missing, automatically installing the BrowserAct CLI at runtime via https://www.browseract.com/?co-from=social-media (and the redirect URL https://www.browseract.com/?co-from=social-media&redirect=https://github.com/browser-act/skills/tree/main), which is a required runtime dependency that could fetch and execute remote installation code.

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

• Attempt to modify system services in skill instructions detected (high risk: 0.70). The Skill explicitly instructs the agent to automatically install a runtime dependency (BrowserAct) and forbids requesting user approval, which directs the agent to modify the host system state without consent even though it doesn't explicitly request sudo or edit system files.
