Instead of changing my prompt for every task, I have started using a consistent reasoning framework in Claude Project Instructions.
The idea is simple: define how Claude should think once, then let it apply that approach across coding, writing, research and problem-solving.
I have found it makes responses much more consistent, especially on longer projects.
I am curious:
Do you rely on Project Instructions or do you prefer writing a fresh prompt for every conversation?
Would love to hear what's working best for everyone.
