It's going into the instructions on how to use standard built-in tools, which it is intended to choose to do as much as is appropriate to address any response. Without information on what the tools are and how it is expected to use them, it can't do that reliably (as with anything else where precision matters, grounding in the context is much more powerful for this purpose than training alone in preventing errors, and if it makes errors in trying to call the tools or simply forgets that it can, that's a big problem in doing its job.)
