 Think of your AI assistant as an eager junior developer who can learn and retain knowledge - but only if you teach them properly. Instead of repeating the same instructions in every prompt, establish a single source of truth through your CONVENTIONS.md file. This approach not only saves time but ensures consistency across all AI-generated code. The key is treating conventions as a living document that both teaches the AI and evolves with your project. You can see [an example of this evolution here](https://gist.github.com/idvorkin/6f506f47bf6c4c57a1ff5a2d24e345dd#conventionsmd).
