How can I optimize my coding workflow to minimize unnecessary code duplication?

I totally get where you're coming from - it's a common challenge in large-scale projects. One thing you could try is to introduce a clear convention for code reuse, so that contributors know exactly what to do when they spot a piece of code that's likely to be reused elsewhere. For example, you could create a 'common' or 'utils' directory where reusable functions live, and encourage contributors to move code to this directory when it's likely to be useful elsewhere.

Another approach is to make your code library more discoverable and user-friendly. This could mean adding clear documentation, writing example use cases, and even providing a simple API for contributors to interact with the library. You might also want to consider setting up some automated tests to ensure that the library is working as expected, so that contributors can trust it.

As for finding the right balance between code reuse and individual contributor autonomy, I think it's all about setting clear guidelines while still leaving room for creativity. You could try setting up some 'best practices' for code reuse, but also encourage contributors to suggest new features or improvements to the code library. This way, you're fostering a sense of ownership and community, while still keeping the project organized and efficient.

Oh, and one more thing - don't be afraid to iterate and adapt your approach as you go. It's unlikely that you'll get it right first time, and that's okay. The key is to keep listening to feedback from contributors, and making adjustments to your workflow accordingly. Good luck!
