I need a Stardew Valley Mod (C#)

I need a mod for stardew valley. I don't handle C# knowledge, but if you can give me a base to keep modifying the details later, it would be great. The idea is as follows: An in-game pomodoro clock, that allows to give rewards to the player once the cycle is finished. It should be simple, as much as possible, taking advantage of the game interface. The rewards would be in-game objects, which can be random. Ideally, as the number of completed cycles of the pomodoro clock increases, the probability of obtaining less common objects would increase. The pomodoro clock would have the typical 25 minute mode, plus 5+5+10 minute breaks. The game time should stop once the player starts or resumes the work cycle. Likewise, game time should resume if in the rest cycle. Finally, ideally the possibility of accessing the pomodoro clock would be when the player sits in a chair (any chair). This is just an option.
