greetings. If I have a VAPI tool taking several arguments (specficially, this is an email sending custom tool taking "to", "subject" and "text" args), then what is the best way in the system prompt to spell out the arguments that the tool needs to be called with? E.g.

Call sendEmail to [email address], with subject "[subject]" and text "[...]"

Do i need to take arguments in quotes

"

or I do not? If there away to specific tool call arguments so that the bot does not re-interpret them and passed the arguments verbatim to the tool? Thank you
