I have used the prompt technique discussed in this thread
And It did wonder to me in terms of the quality of output generated by GPt-4.
The key here IMO is not to add that as description_for_the_model, use that field only to describe the capabilities your plugin offer and extend to GPT-4
And then in your very first prompt use it. I have done several testing and GPT-4 will follow the instructions pretty much to the letter, only couple of misses but it was able to auto correct itself according to my instructions I gave in the prompt.
Gained considerable amount of good output from these prompts.
