I am waiting people to commits their prompt/agents setup instead of the code to call this a changing paradigm. So far it is "just" machine generating code and generating code doesn't solve all the software problem (but yeah they get pretty good at generating code)
If you want an example, I just open-sourced a project which includes the prompts and CLAUDE.md: https://github.com/minimaxir/miditui/tree/main/agent_notes
