What simulators does on Yaver

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

Why simulators is rated Low

This tool performs a read-only operation that enumerates iOS simulators. It retrieves and displays configuration or status data with no side effects, no code execution, no data modification, and no destructive operations. The only potential risk is information disclosure about available development environments, which is minimal in a local dev context.

From the tool's definition 'List iOS simulators' - a query operation that retrieves information about available simulators without modifying, executing, or deleting anything.
