Cursor AI Prompting Framework

This repository provides a structured set of prompting rules to optimize interactions with Cursor AI. It includes three key files to guide the AI’s behavior across various coding tasks.

Files and Their Roles

`core.md`

Purpose: Establishes foundational rules for consistent AI behavior across all tasks.
Usage: Place this file in your project’s .cursor/rules/ folder to apply it persistently:
Save core.md under .cursor/rules/ in the workspace root.

	// An expression simply turns a delegate into a data about itself. So a => a + 1 becomes something like "On the left side there's an int a. On the right side you add 1 to it."
	// Func doesn't carry with it a way to get into itself.
	// Source: https://stackoverflow.com/a/34606818

	// This is a function that will add 1 to the input a.
	// Inside your code, this does exactly that.
	// However, let's say you want to translate this function into SQL. Your code will need to know what this fuction DOES.
	// This is not possibly with just a Func. So...
