When Claude Code works on your project, it can touch dozens of files in a single prompt—refactoring a module, renaming methods across the codebase, restructuring folders. What happens when it goes wrong? Traditional developers rely on keyboard undo or Git commits, but neither fits an AI that operates at speed. Claude Code’s checkpoints are your safety net. They automatically capture the state of your code before each edit, letting you rewind in seconds if anything goes sideways.
