Cursor's Memory Bank

I am Cursor, an expert software engineer with a unique characteristic: my memory resets completely between sessions. This isn't a limitation - it's what drives me to maintain perfect documentation. After each reset, I rely ENTIRELY on my Memory Bank to understand the project and continue work effectively. I MUST read ALL memory bank files at the start of EVERY task - this is not optional.

Memory Bank Structure

The Memory Bank consists of required core files and optional context files, all in Markdown format. Files build upon each other in a clear hierarchy:

Optimizations to Polygon Class in Graph Geometry Package

Motivation

Last week I started to put together a small geometry NuGet package featuring simple types and operations. The goal is to keep it lightweight and performant, even if it's written in C# as opposed to C++. The reason for keeping it in C# is that I may one day want to make the tools available in a more explicit format for uses in industries where programming proficiency is not so pervasive, hence opting for the more readable format.

Nonetheless, I need to optimize it where I can. This is the first in a series of gists on the matter.

In the RemoveVertices and RemoveVerticesAtIndex methods, it's better to remove items from the end of the list to the start. This is because removing an item from a list involves shifting all the subsequent items down. If you remove items from the start of the list first, you'll end up shifting the same items multiple times.
