# gdb and rr Debugging

> Use this tool when you need to debug programs and inspect their internal state, set breakpoints, and step through code to identify issues. It solves problems related to program crashes, unexpected behavior, and performance issues by providing detailed insights into variable values, memory, and register states. The tool accepts structured input commands and outputs debugging information, making it ideal for use cases where in-depth program analysis is required.
