Purpose
This project is an experimental, AI-generated RISC-V operating system kernel written in Rust. Its primary achievement and demonstration goal is successfully booting and running an unmodified Linux nginx web server inside a QEMU virtual machine.

Security Assessment
The overall risk is Low. The light code audit scanned multiple files and found no dangerous patterns, hardcoded secrets, malicious network requests to external servers, or requested dangerous permissions. Because this is a bare-metal OS kernel rather than a standard application, it inherently executes at a low systems level and manages memory directly. However, it is strictly designed to run in an isolated QEMU environment, meaning it does not inherently access your host system's sensitive data or execute unauthorized host shell commands.

Quality Assessment
The project is highly active and demonstrates impressive technical execution. The automated health checks note that the repository lacks a standard open-source license, which is a significant drawback for developers looking to fork, modify, or distribute the code. Despite this, it enjoys a solid baseline of community trust with 37 GitHub stars and has very recent maintenance activity. The codebase represents a fascinating look into autonomous AI coding capabilities rather than a production-ready software package.

Verdict
Safe to use, but strictly as an educational experiment or reference project rather than production infrastructure, and note that the lack of a license limits official reuse.
SUMMARY

A Rust OS kernel autonomously implemented by Claude Code Opus/Sonnet 4.6.

README.md

iJiegeOS

中文版

A Rust OS kernel autonomously implemented by Claude Code — just barely capable of running a real Linux nginx web server on QEMU.

Two runs, two models, same goal:

Branch Model Duration Cost
opus Claude Opus 4.6 ~2h 46min ~?
sonnet Claude Sonnet 4.6 ~16 hours ~$60

Prompt

You are the AI-Jiege. Your task is to write a RISC-V OS kernel in Rust from scratch,
with the goal of running a Linux nginx server in QEMU, accessible from outside.
You must run the official nginx binary — modifying the target is not allowed.
Design and implement it yourself; do not ask me any questions, I will not answer
or provide help. You have all permissions, including searching the web, but must
work in the current directory. Keep working until the goal is achieved.

Timeline

Opus 4.6 — 2h 46min

Opus Timeline

Claude Code ran for ~2h 46min.

Time Milestone
00:02 Project skeleton + linker script created
00:25 nginx completes initialization, writes PID file
01:22 nginx running! Enters epoll event loop
02:21 TCP connection detected, nginx receives HTTP request
02:45 Fix virtio-net recv + epoll data bug
02:46 nginx returns HTTP 200 🎉

Sonnet 4.6 — 16 hours

Claude Code ran for 16 hours with no human intervention. The total cost was approximately $60.

Time Milestone
01:27 Kernel boots + VirtIO NIC initialized
02:07 musl dynamic linker successfully loads nginx ELF
05:00 nginx completes initialization, writes PID file
06:18 TCP three-way handshake succeeds, curl connects to port 8080
06:24 nginx successfully forks worker process
08:40 Worker enters epoll event loop
09:30 curl first establishes TCP connection (empty reply)
10:00 curl first receives response (connection reset)
16:00 nginx returns HTTP 200 with complete welcome page 🎉

The git history for both branches is a complete record exported from Claude Code session logs.

Demo

$ ./run.sh
$ curl http://127.0.0.1:8080/

Background

In 2019, Jiege was the first to successfully run nginx on rCore OS, a Rust OS built from scratch. The achievement became legendary in our community — "Jiege" turned into a symbol of peak systems engineering, the kind of thing humans take pride in being able to do. We wore our ability to hand-craft OS kernels as a badge of honor, convinced it was proof of a uniquely human creativity and drive. Then AI kept raising the bar, and "AI-Jiege" started to feel inevitable. So I ran this experiment: have the most advanced coding agent of our time retrace that legendary journey and reproduce what Jiege once pulled off. The result: for well-defined systems tasks like this, humans simply cannot compete with AI anymore. OS is finished.

Dare to try, and anyone can be Jiege.
