Andrej Karpathy Skills Cursor Vscode
A 65-line Markdown rules file that nudges Cursor and VS Code AI assistants toward more deliberate coding.
Install it if you're curious whether 65 lines of rules change how Cursor or VS Code writes code — it's free, take a minute, and judge for yourself. The author himself says the effect is hard to tell apart from model noise, so treat it as a prompt-engineering experiment, not a guaranteed upgrade. If you need predictable, enforceable AI behavior, more structured rule sets (cursor-rules templates, or your own multi-file rules describing architecture and standards) will do more for you. Also note the VS Code Marketplace install throws a warning because the publisher isn't verified — the author expects to apply for verification starting August.

Skip Andrej Karpathy Skills if you need a verified publisher, configurable rules, or any way to measure whether AI output actually improved — this is one fixed 65-line file and the author says the effect is hard to tell.
Installing from the VS Code Marketplace shows an unverified-publisher warning, which some corporate security policies treat as a blocker or require an approval ticket.
It's free, so there's no tier math to do — the comparison that matters is time versus alternatives. You spend a few minutes installing and testing it. A curated cursor-rules template or a hand-written multi-file rule set costs the same zero dollars but more setup time, and in exchange you get rules that name your architecture and standards instead of four generic principles.

About Andrej Karpathy Skills Cursor Vscode
Andrej Karpathy Skills is a single Markdown file — 65 lines long — that you install into your AI coding assistant in Cursor or VS Code. It lays out four principles, the first being "Think Before Coding," and packages them so the assistant reads them as rules before it generates or edits code. The project started as a Claude Code extension that attracted roughly 4,000 stars in a matter of days (it went from 3.5K to 3.9K stars in one day per the author's blog), and this version repackages the same file for editors that don't run Claude Code. The creator fired up Codex CLI and turned it into a VS Code and Cursor extension, then published it through the VS Code Marketplace and Open VSX. Installation is quick — no dependencies, no configuration screens, just the extension and its baked-in rules text. The author is candid about the hard-to-measure impact: due to the non-deterministic nature of these models, he "found it hard to tell" whether results improved, though he noticed the assistant seemed reluctant to make changes during a simple refactoring test. It's an experiment in minimal prompt engineering rather than a productivity suite: can a few well-chosen lines meaningfully change AI behavior? If you want structured, multi-file rule sets that describe your architecture and coding standards, look at cursor-rules templates instead.
Behind the Verdict
What this tool actually is: one Markdown file, 65 lines, containing four principles the author describes as derived from Andrej Karpathy's coding philosophy — the first being "Think Before Coding." The packaging exists so that the file installs as an extension in Claude Code, and in this version in Cursor and VS Code. The creator's own account is refreshingly honest: he tried a simple refactoring and had "the idea that it was very reluctant in making changes," but when asked "Was the result better? I'm not really sure." He also raises the obvious skeptical question — companies spend millions training these models and employ engineers to improve output, so should 60 lines of text including "Think before coding" make all the difference? The counter-argument he offers is social proof: nearly 4,000 stars on the original repository. Strengths: it costs nothing, installs in seconds from the VS Code Marketplace or Open VSX, has no dependencies, is open source on Codeberg, and is trivially forkable if you want to rewrite the rules to match your own standards. It's a cheap way to run your own A/B feel for whether rule files shift assistant behavior. Weaknesses: effectiveness is subjective and inconsistent because LLM output is non-deterministic; there is no measurement mechanism, no API, and no advanced configuration; and the VS Code Marketplace listing is not from a Verified Publisher, so you get an install warning until the author can apply after six months (starting August). On Cursor, the publishing path ran through Open VSX and the Eclipse Foundation, which the author describes as cumbersome — a buyer-side non-issue, but it tells you how lightly-tooled this project is. Where it fits: individual developers who already use Cursor or VS Code's AI assistant, like Karpathy's writing, and enjoy tinkering with prompt engineering. Where it doesn't: teams that need vetted, publisher-trusted extensions, or anyone who wants a documented, repeatable change in AI output quality. Compared with cursor-rules templates or a full custom rule set covering architecture and coding standards, this is the smallest possible intervention — which is exactly the point, and exactly the limitation.

Real-world workflow fit
Concrete scenarios for the personas Andrej Karpathy Skills Cursor Vscode actually fits — and what changes day-one when you adopt it.
You install the extension from Open VSX, open a repo, and ask the assistant for a small refactor to see how the "Think Before Coding" rule lands.
Outcome: You get a quick, low-cost read on whether the rules file visibly changes the assistant's willingness to make changes, without touching your project setup.
You install from the VS Code Marketplace, accept the unverified-publisher warning, and run the same prompt on a branch with the rules and on a branch without them.
Outcome: You get firsthand experience to compare against structured cursor-rules templates before deciding which approach your team should standardize on.
You clone the open-source 65-line file from Codeberg and rewrite the four principles to match your team's coding standards.
Outcome: You end up with a minimal, custom rules file you fully understand, instead of adopting a larger rule pack.
Use Cases
- Apply the "Think Before Coding" rule inside your Cursor or VS Code AI assistant
- Run a personal experiment in minimalist prompt engineering for code generation
- Add a Karpathy-style rules file without any complex setup
- Compare assistant behavior with and without the rules installed
- Fork the 65-line file and rewrite the rules for your own coding standards
Limitations
- The extension is not from a Verified Publisher on the VS Code Marketplace, so you get a warning during install; the author says he can only apply for verification starting August, after six months with at least one published extension.
- Effectiveness is subjective and inconsistent because model output is non-deterministic — the author tried a simple refactoring, felt the assistant was "very reluctant in making changes," and still could not say whether the result was better.
- The rules file itself is only 65 lines, so it isn't a structured system covering your environment, coding standards, and architectural constraints — the author points to typical Cursor rules for that.

- →From Claude Code version: install the Cursor/VS Code build from Open VSX or the VS Code Marketplace — same 65-line file, different packaging.
- →From cursor-rules templates: you can't import them; this file replaces your rules text with its four principles, so keep a copy of your old rules first.
- ↗To cursor-rules templates: export your own constraints into a structured multi-file rules setup, since this extension holds only four generic principles.
- ↗To a custom rules file: copy the 65 lines from Codeberg as a starting point, then add your architecture and coding standards.
- ↗To no rules file: uninstall the extension; nothing else on your machine references it.
