Neander Reference

The Reference is a practical, example-driven guide for writing Neander programs, aimed at the AI agents that author them.

Do not point an agent at a hosted copy of the Reference — including this one.

A Neander runtime delivers its own Reference to the agent in-band (in response to the empty program), as defined by the Specification. That delivered Reference matches the exact language version the runtime implements.

A static copy published here (or anywhere) may be for a different version than the runtime an agent is actually connected to. An agent that writes programs against the wrong Reference will produce plausible-looking code that does not behave as intended — and it fails silently at authoring time. The copy below is illustrative only: it shows humans the kind of Reference a runtime serves.

It is not an agent input.

For humans: what the agent sees

This lets you understand what your runtime hands to an agent and how programs are expected to be written, without having to instrument a live runtime.
