Add a built-in "code-check and verification" functionality please!!!

Your platform should have a built-in check functionality so when the user ask for something to be done, it keeps at it testing, retesting, coding, recoding and rechecking until it works. It is infuriating when it says, yes, I know what the issue is and then says it has done it for that not to work. I rather you charged me 10 credits for that “safe” approach to integrating/ adding functionality that the 100-200 credits it takes to prompt, re-prompt trying to get it fixed/ done. Please, do this, it would be life-changing!!!
