frequently your session/context may drop (e.g. claude crashes, or your internet dies, or your computer restarts, etc.). Claude does best when it can recover the context and understand the current situation from clear documentation, rather than trying to reverse engineer intent and structure from an existing code base. Also, the human frequently does read the code docs as there may be places where Claude gets stuck or doesn't do what you want, but a human can reason their way into success and unstick the obstacle.
