Most people use AI like a very fast stranger. They open a blank chat, explain who they are and what they are doing, get something useful, close the tab, and then do the whole thing again tomorrow. The explaining is the work, and it is thrown away every single time.
The fix is not a better prompt. It is giving the tool a memory of you that persists, and then writing down the ways of working you repeat, so they run the same way every time instead of being reinvented. Everything below is a version of that one idea.
Build it in this order. Each step is useful on its own, and each one makes the next easier. If you stop after step two you will already have most of the benefit.
