With Helpful Spouses installed you can control who will do what chores, and under what conditions. Not only that but it also adds a few new chores to the game like petting all the animals in the Barn/Coop and filling the water troughs in your Slime Hutch. The default configuration is intended to be a lore-friendly version. So Alex has a 100% chance of feeding your pet because he's always owned a dog, and he's used to taking care of his pets, Shane is more likely to pet the animals because he helped around the Barn at Marnie's, and Maru learned a thing or two from her mom so she's more likely to repair the fences.

Helpful Spouses is safe to add/remove at any time.

This Mod requires the Custom Chores as well as some Custom Chore content packs to work.

BirthdayGift - On an NPCs birthday, your spouse will give you a gift that they like or love.
FeedTheAnimals - Animals in Barns/Coops will be fed.
FeedThePet - Your pet's water bowl will be filled.
MakeBreakfast - Spouse will give you a breakfast item in the morning.
PetTheAnimals - Animals will be loved.
RepairTheFences - Fences will be repaired.
WaterTheCrops - Hoed dirt will be watered.
WaterTheSlimes - Water troughs in slime hutches will be filled.

After you run the game for the first time, the default config.json will be generated to the HelpfulSpouses folder. The following general options are available to customize:

Daily Limit - Default 1. The maximum number of chores that a spouse will perform in one day. Set to 0 to disable.
Hearts Needed - Default 12. The minimum number of hearts required before a spouse will do chores.
GlobalChance - Default 1.0. The chance that a spouse will do any chores on a given day.
Spouses - For each spouse, configure what chores they can do, and what chance they have to do it.

Each Spouse will have a key for their name, and a list of chores that they can do. Every morning the mod will start with the first chore in that Spouse's list, and based on the Chance provided the spouse will either perform the chore or skip it. It'll continue to cycle through the chores in the given order until it has gone through all of them or the daily limit has been reached.
