Your prompt is pretty basic. Both Claude Code and Github Copilot having similar features. Claude Code has `init` which has a lot of special sauce in the prompt to improve the CLAUDE.md. And github copilot added a self-documenting prompt as well that runs on new repos, and you can see their prompt here https://docs.github.com/en/copilot/how-tos/configure-custom-...
Reading their prompt gives ideas on how you can improve yours.
