How the agent did it
- Define a bare-metal educational operating-system goal.
- Use Cursor with Claude Opus to generate Rust system components.
- Add a terminal, programming modes, editor and lessons.
The developer behind SmileyOS describes using Cursor to build a real educational operating system rather than a browser imitation. The intended users are children learning programming in an offline environment. The author says the project took a month and nearly €3,000 in AI subscriptions, producing roughly 100,000 lines of Rust with Cursor and Claude Opus 4.5 Max.
The system includes a bootloader, graphics stack, persistent filesystem, terminal and a small programming language with shell, game and application modes. An integrated editor and progressive lessons let users run programs without rebuilding the operating system. The concrete hardware claim is a successful test on a Dell Inspiron 910, with i686 described as fully working. Other listed architectures include abstraction work, so the account should not be read as proving equal hardware support across all targets.
The author chose the educational scope and reports testing the resulting system, but does not publish a detailed approval or quality-assurance sequence in this forum post. The useful pattern is to anchor an ambitious generated project to a bootable target and a demonstrable user workflow. Code volume and spending are reported development facts, not evidence of reliability, security or suitability for children without further review.

Frequently asked questions
What hardware test is actually reported?
The developer names a Dell Inspiron 910 and describes i686 as fully working.
Are all architectures equally demonstrated?
No. The post separates working i686 support from abstractions for x86_64, ARM64 and RISC-V.
Does code volume prove quality?
No. The reported lines and subscription spend describe scale; the source does not establish comprehensive reliability or security testing.
More details
Remaining steps
- Test the i686 build on a Dell Inspiron 910.
- Distinguish working hardware support from other architecture abstractions.
