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

• Third-party content exposure detected (high risk: 0.85). The workflow’s runtime path includes loading a user-supplied target URL via navigate_page(url: "<target-url>") and then ingesting the resulting page/trace/network text through the Chrome DevTools MCP tools (e.g., performance_start_trace/list_network_requests), which can include outsider-authored free text from the fetched web page.

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

• Potentially malicious external URL detected (high risk: 0.90). The skill requires running a local MCP server via the command that fetches and executes remote code ("npx -y chrome-devtools-mcp@latest" used in the chrome-devtools MCP config), which is a runtime external dependency that executes remote code and is required for the skill to operate.
