WHAT IT DOES

What get_console_error does on Browser

AI agents call get_console_error to retrieve information from Browser without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why get_console_error is rated Low

This tool retrieves diagnostic/debug information (console error logs) with no side effects. It is a passive read operation that queries existing console state without executing code, modifying data, or triggering external operations. The context of sibling tools (execute_script, close_tab) that perform actual browser automation reinforces that this tool is informational only.

From the tool's definition Tool name 'get_console_error' and description 'Get console error messages' indicate retrieval of already-logged error data from browser console; no modification, deletion, or code execution involved.
