Most people install it, hit Tab a few times, and never touch the parts that actually save hours. This guide walks the real workflow in 2026 — and flags the bits worth ignoring.\n\n## What changed in 2026\n\nThe big shift is that Agent mode (formerly Composer) has gone from a novelty to the default way many people do larger tasks. Instead of editing one file, you describe a feature and Cursor plans it, edits across multiple files, runs terminal commands, and shows you a reviewable diff.\n\nTwo other things matter. First, the model picker is now front and center: you choose which frontier model handles a request, and heavier models cost more against your usage allowance. Second, pricing has drifted toward usage-based billing on top of the flat plan, so the \"just throw the whole repo at it\" habit has a real cost. Treat any specific price or limit here as directional and check Cursor's current pricing page before you commit — these numbers move.\n\n## The four ways Cursor writes code\n\nCursor has four distinct AI entry points. Using the wrong one for the job is the most common beginner mistake.\n\n| Surface | Best for | Trigger | Watch out for |\n|---|---|---|---|\n| Tab | Inline autocomplete and quick refactors as you type | Just type | Gets pushy in code it does not understand |\n| Cmd+K | Targeted inline edits or generation in a selection | Cmd+K | Keep the selection small and specific |\n| Chat (Cmd+L) | Questions, explanations, and planning | Cmd+L | Will not edit files unless you tell it to |\n| Agent | Multi-file features end to end | Agent panel | Read the whole diff before accepting |\n\nRule of thumb: Tab for flow, Cmd+K for a surgical change, Chat to think out loud, Agent when a task touches several files. If you only learn one new habit, make it Cmd+K — it is the fastest way to get a precise edit without a long conversation.\n\n## Setting it up without the friction\n\nSetup is genuinely painless. On first launch, Cursor offers to import your VS Code extensions, settings, and keybindings in one click, so your themes and tooling carry over. Sign in, then open the model settings and pick a sensible default model rather than always reaching for the most expensive one.\n\nTwo settings are worth checking on day one. Turn on Privacy Mode if you work on anything proprietary — it tells Cursor not to retain your code. And point Cursor at your real project folder, not a scratch file, because most of its intelligence comes from seeing your codebase.\n\n## Rules files and @-context: where power users win\n\nThe difference between \"fancy autocomplete\" and \"actually useful\" is context, and you control that.\n\nA project rules file (a `rules` entry or `.cursorrules`) lets you tell Cursor your conventions once: framework, folder structure, testing style, libraries to prefer or avoid. Every request then respects those rules instead of inventing its own patterns.\n\nThe `@` symbol pulls in context on demand. `@Codebase` lets Cursor search your whole project to answer a question; `@Files` scopes a request to specific files; `@Docs` pulls in indexed documentation for a library. Being explicit here beats hoping the model guesses right — and it keeps requests focused, which also keeps them cheaper.\n\n## Watch the token bill\n\nBecause heavier requests draw on usage-based billing, cost discipline is a real skill. Broad prompts that attach `@Codebase` and a top-tier model on every keystroke are the fastest way to blow through your allowance.\n\nWhat to skip: do not run Agent mode on a vague prompt in an unfamiliar codebase and accept the result blind. It produces plausible-looking changes that can be architecturally wrong, and the cleanup costs more time than you saved. Scope tasks, use a cheaper model for routine edits, and reserve the expensive model for genuinely hard reasoning.\n\n## FAQ\n\n**Is Cursor free?** There is a free tier with limited fast requests, plus paid plans that add more usage. Verify the current limits yourself, since they change often.\n\n**Do my VS Code extensions work?** Yes. Cursor is a fork of VS Code, so extensions, themes, and settings import directly and behave the same.\n\n**Should I let Agent mode run terminal commands?** Only when you can see and approve each command. It is powerful for scaffolding, but blind auto-run in a real project is a bad idea.\n\n**Does Cursor replace knowing how to code?** No. It accelerates people who can read a diff and catch a bad suggestion; it amplifies confusion for people who cannot.\n\n## Where to go next\n\nIf you are weighing which AI subscriptions actually earn their keep, read our take on whether [ChatGPT Plus is worth it in 2026](/blog/is-chatgpt-plus-worth-it-2026).
