Zerolang

Zerolang is an experimental programming language designed for AI agents to work with program semantics directly rather than raw source text. Humans request outcomes, agents query and edit the program graph with compiler-checked patches, and results remain reviewable as text projections. The project describes itself as built by Vercel Labs and emphasizes a tighter agent loop where the compiler validates edits before they affect the program database.

The language provides agents with explicit handles like symbols, node IDs, graph hashes, types, and effects to target semantic structure instead of line ranges. Stale or invalid edits fail before storage. Readable `.0` file projections stay available for human review and occasional manual editing, while agents typically interact through graph queries and patches.
