Is generation of reliable tailored code helpful?

Hey devs, I am building an agentic AI to be the AI tool for developers. I was wondering if it'll be helpful if the agentic AI generates the 1st working ver of app in one prompt with re-usable code that is tailored to project specs from Figma/Motiff, Postman or requirements docs. Additionally, what if the agentic AI also helps with elevating coding skills on every project, does code review, creates unit test cases, helps with task management.

Does this type of an Agentic AI/AI tool help developers?
