Cursor AI

Imagine typing the start of a function signature in your code editor, and before you finish the parameters, a complete, context-aware implementation appears in ghost text. You hit Tab, tweak a variable name elsewhere, and the suggestions ripple across your entire codebase—instantly. This isn’t science fiction; it’s Cursor AI, the VS Code fork that’s redefining how developers code in 2026. But what makes it feel like magic? It’s not just a bigger model plugged into an editor—it’s a sophisticated engineering stack solving latency, context, and quality in ways that outpace competitors like GitHub Copilot.[1][2] ...

This tutorial explains how modern AI agents (like those in Cursor, IDE copilots, and autonomous coding tools) create, maintain, and execute to-do lists — and how you can build the same capability from scratch to production. This is not a UX trick. A to-do list is the core cognitive control structure that turns a language model from a chatty assistant into an agent that finishes work. 1. Why To-Do Lists Matter for Agents Large Language Models (LLMs) do not naturally: ...
