## Why check_installation is rated Low

This is a diagnostic read operation that queries the system for installation status. It retrieves information about whether Frida is present and functional, similar to version checks or system status queries. No data is created, modified, deleted, or executed as a result of this tool's execution. The low severity reflects minimal risk even if called inappropriately—it merely reports facts about the system state.

From the tool's own definition: "Tool performs a check/query operation ('Check if Frida is installed') with no side effects, modifications, or external state changes. It returns installation status information only."

## Use case

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