# OAGS — Open Agent Graph Standard
# https://oags.dev

> A website serves an AGENT a compact GRAPH SCENE (typed blocks + typed edges, with
> first-class honesty about what is missing) instead of a page. The agent finds the
> parsing schema on the site itself, like XML.

Open-standard claim is aspirational until a second, independent adopter parses a scene cold.
