What is the primary goal of the project described in the transcript?	To teach Claude how to set reminders that occur at a specific point in the future using tools.
What is one specific limitation Claude has regarding time that requires a dedicated tool?	Claude does not always know the exact time of day, only the current date.
What is the second time-related challenge Claude faces that needs a dedicated tool?	Claude does not always perfectly handle time-based addition (e.g., calculating days from a specific date).
What is the third challenge Claude faces regarding reminders?	Claude has no inherent mechanism or concept for setting reminders in the future.
What is the function of the first tool to be created, `getCurrentDateTime`?	To retrieve the current date and time.
What is the purpose of the second tool, `addDurationToDate`?	To add a specified duration to a given date or time.
What is the first step in creating a tool function?	Writing a plain Python function that will be called automatically on a server.
What is the most important best practice when writing tool functions?	Use well-named and descriptive arguments.
What is the second best practice when writing tool functions?	Validate the inputs passed into the function and raise an error if validation fails.
