agda-categories, informalized
4,541 declarations from the agda-categories
library, each paired with an informal, LaTeX-flavoured natural-language
statement written by GLM-5.2. The natural language is written to be precise

reconstruct the formal Agda source from the prose alone.
Declarations were extracted with a fork of Agda
that dumps one JSON record per named declaration (with its full source range)
