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

• Third-party content exposure detected (medium risk: 0.30). In the required workflow, the agent ingests outsider-provided free text only as the target URL for navigate_page(url: "<target-url>"), and then reads the page’s contents via the Chrome DevTools MCP trace (e.g., performance_start_trace and subsequent analysis), which can include attacker-controlled text rendered by the target page.

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

• Potentially malicious external URL detected (high risk: 0.90). The skill's MCP config suggests running the command "npx -y chrome-devtools-mcp@latest" (appearing in the config JSON) which will fetch and execute remote package code at runtime, creating a high-confidence runtime external dependency.
