Unity Insight: a typed code-to-asset index cut agent tokens 53% and wall-clock 52% versus a grep-style exploration agent
arXiv 2609.27585·low signal
Unity scenes and prefabs link to code through GUIDs in .meta and YAML files, which shell search and code-only indexes cannot follow. A persistent index exposed through typed query tools, in production in Tuanjie Codely since 28 July, halved tokens and time on 28 paired questions (p<0.004). The same idea applies to any repo where serialized config holds the links between parts: index those links for the agent instead of hoping grep finds them.
