This is the dumbest project I have ever seen. Why does it have so many upvotes and comments? Because there are a bunch of idiots here who need to add meaningless stuff to their empty and pointless papers. Only so-called pure academics would try to build such an index for code. File directories, search, and the built-in code parsing capability of compilers basically allow AI to locate any problem within 5 to 30 seconds. Even in the worst-case scenario, the problem is definitely not the lack of a so-called code index. To everyone participating in this discussion: how much have you actually used Claude Code? I have built several large projects with it without writing a single line of code myself, and I have never thought that code location or indexing was a problem at all.
