fix(ai): pass FunctionDeclaration#description arg to internal class

[thatfiredev]

It seems like the value set in FunctionDeclaration#description was never making it to the API.

Aside: I wonder if this is why some function calls would sometimes fail (ie. the model wouldn't know which function to call) Nevermind, I found a bug in the implementation I was testing with.
