I have been pondering this and I think it's likely a gap that will get filled sooner or later.
Right now there's just so much value in building LLM tools for experts that everyone is focusing on that. But surely at some point we'll have bespoke harnesses that exist exactly to solve this kind of thing.
I think this can start with constrained problem spaces like "you are a WordPress developer, you solve problems for people with enough expertise to know they are looking for a WordPress developer" and incrementally expand from there. Maybe I'm naive but I think you can probably get pretty far with this today just by writing loads of skills and picking the right technical preferences to encode in them.
