Ask HN: Is it worth to build custom GPT for WordPress theme files?

My WordPress theme sometimes doesn't work as expected. For example, the simple custom Javascript (which works fine in 3 files environment on my local laptop and renders a tooltip with text on cursor hover) doesn't work in the theme's environment. Is it worth the time to feed the theme files to a custom GPT and expect it to provide minimally congruent answers in human language as well as in code about my WordPress theme?

If yes, then should I pre-train this GPT on a bunch of WordPress themes (I have currently the files of ~5 WP themes) or should I use some type of "zero-shot" training?

(seems like a not bad product idea, but may be not?)
