Vercel Labs Ships 'Zero' (.0) — An Experimental Systems Programming Language Designed for AI Agents to Read, Repair, and Ship Native Programs

GitHub·medium signal

Vercel Labs released Zero, a new systems programming language with the .0 file extension built around 'everything is explicit' — no hidden allocators, no implicit async, no magic globals. The agent-first toolchain includes structured JSON diagnostics, binary size reports, and typed repair metadata so AI agents can autonomously fix compiler errors without human interpretation. Commands like 'zero routes' analyze web route surfaces and 'zero skills' outputs capability descriptions following Vercel's Agent Skills spec, consumable by Claude Code, Cursor, Codex, and 17+ AI coding assistants.
