Cursor has become the go-to AI-powered IDE for professional developers. Key techniques: 1) .cursorrules file for project-specific behavior - define tech stack, code style, patterns to use, things to avoid. This dramatically improves AI suggestion relevance. 2) Composer (Cmd+I) for multi-file editing - describe a feature and Cursor creates all required files following existing patterns. 3) @ references for context management: @file, @folder, @code, @docs, @git to precisely control what context the AI sees. 4) Terminal AI with Cmd+K in terminal for AI-powered command generation. 5) Custom keyboard shortcuts and settings.json optimizations for faster accept/reject workflows. 6) Git integration for AI-generated conventional commit messages. Key tip: start .cursorrules with role definition ("You are an expert TypeScript developer") then add specific project conventions.
