GitHub Copilot is also very good because it has the context of your open files or selected text and will pretty regularly give you exactly what you want for the next line of code.
I will say it's much weaker for less popular libraries and programming languages, but for most full stack engineering tasks it gives a huge productivity boost
I don't think the grand OP is downplaying anything at all.
And generally speaking, 10% increase in productivity is extremely (repeat 3 times) significant. Remember most developed countries' GDP only grow <3% annually.
``` Given these X files, help me assess how best to implement feature Y. Ask any clarifying questions that may assist with writing a best practice solution. *File 1* *File 2* *File 3* ... ```
If the context length is a problem I'll use claude-100k.
Pretty much always results in good quality code.
I'll then typically open a new window context and get it to review according to best practices highlighting missing e.g. error handling or possible edge cases.
