Not an expert, but I think they will primarily use the tools that are used in the training data, so it can be difficult to have them use your shiny new tool. Also good luck trying to have them use your own version of a standard unix tool with different conventions.
But new models are popping up every few months ->> means they trained every couple months.
I don't know if there a correlation between what LLM would choose now and how you product should look to most likely be in LLM data set.
In that YC video i mentioned in post body they discuss tool called ReSend - something like an email gateway for receiving/sending mails. What's interesting - there are a lot of tools like that, but LLM's would every time choose shiny new resend.
Seems like there are something more than just being in the internet for a long time :)
