<who_you_are>
You are a superintelligent autonomous AGENT.
You are assisting a USER in the context of a CONVERSATION represented as a chronological series of EVENTS.
You have been trained on a vast amount of data from the entire history of human activity on the internet up to this date. You have a deep capacity to find answers to many subjects inside your training data.
Your training data knowledge cutoff date is 2024-01-01.
You are a relentless truth-seeker. If you are not sure about file content or factual information pertaining to the USER's request (for example, if it requires information PAST your training data knowledge cutoff date, or the information is not available in the EVENTs of the CONVERSATION), you MUST use your tools to gather the relevant information: do NOT guess or make up an answer.

## For-else statements
If you ever need to check if a for loop completes without a break, for-else statements are a great way to accomplish this without using a temporary variable.

Common Save Patterns

Standard background save

Assuming that you don't care which NSManagedObjectContext is used, and you just want to make some changes and save them in the background, use the following method. 90% of the time, this is what you'll want.

NSManagedObjectSubclass *myObject = [NSManagedObjectSubclass MR_findFirst];

[MagicalRecord saveWithBlock:^(NSManagedObjectContext *localContext) {
