Yeah no thanks I'll just take that time and code the feature myself, while you're still pulling out your hairs on "crafting" the perfect pRoMpT
I have a cursor rule file which details my project structure, tools, commands to build, test, etc. Adds some do's and don'ts. This was quite lengthy to do initially on existing projects, cursor is able to assist with generating the first take which i manually reviewed and revised.
Since then I just tag a couple of files, explain what i want, and switch to another worktree and work on another feature while the first is being done.
Claude and Gemini both look at the file structure and match it, naming, etc.
