How an operating system got built from scratch by AI coding agents run like an engineering organization: what worked, what broke, and what the machine said when it disagreed. Every claim traces to a commit.

  1. I ran AI coding agents like an engineering organization. They shipped an operating system you can boot in your browser.A from-scratch graphical OS that boots in your browser, built in 73 days by AI coding agents run like an engineering organization.
  2. Why an operating system is the perfect stress test for an AI coding agentMost demonstrations of AI coding agents are staged on ground that flatters them. An operating system is the opposite.
  3. 512 bytes to a graphical hello world, and the font bug that took 14 builds before breakfastFourteen numbered debug builds in one evening, and what it teaches about binary-search debugging with an agent that cannot see the screen.
  4. The mouse saga: SMI deadlocks, a byte-order guess, and locking a protocol from a raw stack dumpSMI deadlocks, a byte-order guess, and locking down a BIOS callback convention by reading a raw stack dump like a crime scene.
  5. FAT12 from scratch, and "the ACTUAL root cause": what confidently wrong looks like, five times overWhat confidently wrong looks like five times in one afternoon, and the discipline that finally ended it.
