list_watchers

What list_watchers does on Js Reverse

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

Why list_watchers is rated Low

This tool only reads and returns information about currently active watchers in the debugging session. It has no side effects, cannot modify data, and cannot execute code or trigger external operations. It is purely informational, making it a Read category tool with low severity since even if misused by an AI agent, the worst outcome is seeing what variables are being watched—harmless information disclosure.

From the tool's definition Tool description states it 'Lists all active global variable watchers' — a query operation that retrieves and reports existing debugger state without modifying or executing anything.
