Vercel Labs introduces zero, a systems Programming Language designed so AI agents can read, repair, and ship native programs. Vercel Labs 01 / 09 · Overview Zero The Programming Language for Agents An experimental systems language that gives AI agents structured diagnostics, typed repair metadata, and machine-readable docs - alongside sub-10 KiB native binaries. Systems Language Agent-Native v0.1.1 Apache-2.0 Experimental Context 02 / 09 · Why Zero Exists The Agent Repair Loop Problem Most programming languages produce compiler output written for human readers - unstructured text that AI agents must parse to determine what failed and how to fix it. This creates a fragile loop. * Agent writes code - compiler emits an error as unstructured text * Agent parses text - error format can change between compiler versions * No repair hint - there's no built-in concept of a "repair action" * Human steps in - the loop requires manual intervention to resolve errors Zero was designed from day zero so agents can read the code, interpret the diagnostics, and repair the program - without human translation. Core Feature 03 / 09 · JSON Diagnostics Structured Compiler Output Running zero check - json emits machine-readable diagnostics instead of plain text. Every error includes a stable code, a human message, a line number, and a typed repair ID. $ zero check -json {"ok": false...
