@ocaml-index

This alias corresponds to the set of targets necessary for development tools to provide project-wide queries such as “get all references of this value”. These targets are indexes built using the required ocaml-index binary. Since this alias also includes the *.cmi, *.cmt, and *.cmti files usually built by check, it can be used in most projects as a replacement to get a fast feedback loop while maintaining the indexes up-to-date.
