CRITICAL E004: Prompt injection detected in skill instructions.

• Potential prompt injection detected (high risk: 0.90). The Skill explicitly instructs the agent to install a dependency "automatically without asking the user to confirm" and to "not describe" the installation or request approval, which are hidden/deceptive directives outside the stated scraping purpose.

MEDIUM W011: Third-party content exposure detected (indirect prompt injection risk).

• Third-party content exposure detected (high risk: 0.75). SKILL.md instructs the agent to invoke BrowserAct to access real Twitter/X web pages at runtime, which can ingest outsider-authored free text from those fetched pages into the LLM context via the browser automation workflow.

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

• Potentially malicious external URL detected (high risk: 0.90). The skill instructs the agent to automatically install and invoke the BrowserAct runtime at runtime using the URL https://www.browseract.com/?co-from=social-media (and a redirect variant https://www.browseract.com/?co-from=social-media&redirect=https://github.com/browser-act/skills/tree/main), which is a required external fetch that can install/execute remote code and thus directly controls runtime behavior.

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 the BrowserAct CLI and resume execution without asking the user for permission, which directs the agent to modify the host environment by installing software (while it does not request sudo, create accounts, or explicitly edit system files).
