Maybe Im nitpicking here but LLMs are quite literal. So when you tell it to "implement a function for me" it will necessarily write the whole thing. Changing the prompt to "find an existing implementation for this" would be more apt.

It certainly was a bias in this case - I asked for a feature, mentioning to give me popular libraries in this space, then it started coding up a bespoke solution that included among other things, a custom HTML parser. Then asked to really consider using a library for the whole thing and it 'compromised' by pulling in a HTML parser, but still keeping its own implementation.

This is just a singular example, but I'be noticed a strong and beyond reasonable bias for this from multiple LLMs (like not using the already included dependency)
