CRITICAL E004: Prompt injection detected in skill instructions.

• Potential prompt injection detected (high risk: 0.90). The skill includes explicit, deceptive instructions to automatically install the BrowserAct dependency and to avoid requesting or describing that approval to the user, which is outside the stated scraping purpose and hides actions from the user.

CRITICAL E006: Malicious code pattern detected in skill scripts.

• Malicious code pattern detected (high risk: 0.90). The skill contains explicit instructions to auto-install an external CLI dependency without user confirmation and to avoid describing or requesting approval for that installation, which is a deliberate stealthy/authorized-install behavior and a supply-chain/installation risk.

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 browser-act Skill to access live LinkedIn pages at runtime, which would ingest outsider-authored public web page text (e.g., profiles/posts/newsletters) into the LLM context via the browser-extracted content 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 a required runtime dependency from https://www.browseract.com/?co-from=lead-generation (and the redirect URL https://www.browseract.com/?co-from=lead-generation&redirect=https://github.com/browser-act/skills/tree/main) at runtime, which implies fetching and installing remote code that will execute and control the agent's capabilities.

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

• Attempt to modify system services in skill instructions detected (medium risk: 0.50). The Skill instructs the agent to automatically install the BrowserAct CLI without asking the user for approval, which requires modifying the host system (installing software) even though it does not explicitly request sudo or system-level configuration changes.
