"Hey Claude/Cursor/Whatever, create this amazing finance web app with kickass features.
**MAKE IT GOOD, DON'T MAKE MISTAKES**"
If this was enough to build a decent product, I'd be out of a job, but unfortunately for you, and fortunately for me, it is not (yet).
As potent a tool as LLMs are, one of the first things you should learn is that they should not be trusted implicitly. They can and will lead you down the wrong rabbit hole if you, the developer, do not know your subject well enough. AI-assisted development is a bit of a dance: You need to know when to give control to the tool, when to take back control for a more measured approach, with more targeted prompts (and the eventual manual coding).
In essence, you need to know the tools, the frameworks, the features of each and most importantly the limitations before you can start pushing AI to produce truly serviceable products (and not a dime a dozen PoC)
