That is bending the barrel to align the scope. What’s interesting is that the authors mention the cause of the failed calls, “…a model may generate a tool or field name that it has seen during the training, even if it does not exist in the current production environment. For example, it may generate search_web when the available tool is web_search, or use city_name when the active schema expects location”, but then failed to see that it’s also the solution. If you call it “web_search” but it calls it as “search_web” then just rename your function to “search_web” and let the problem resolve itself.

Things get more interesting if you don’t give it a call syntax and just see what it does based on the name alone.
