AI Agent Builds Rust Kernel Booting Linux Userspace in 11 Days

CIQ published an experiment report introducing Human-Directed Agentic Engineering (HDAE), in which humans define architecture, constraints, milestones and acceptance criteria while an agent autonomously implements, executes, diagnoses and revises. Over eleven days a single persistent coding-agent task produced Ginux, a Rust-first x86-64 kernel that boots via UEFI, implements its own core OS mechanisms and a Linux compatibility layer, runs selected unmodified Alpine Linux programs, and boots a Rocky Linux 10 userspace with systemd to multi-user.target. The authors stress it is a research prototype with narrow compatibility and hardware coverage, no independent security audit, and no production-readiness claim.
