Claude can use use tools to do that, and some different code indexer MCPs work, but that depends on the LLM doing the coding to make the right searches to find the code. If you are in a project where your helper functions or shared libs are scattered everywhere it’s a lot harder.

Just like with humans it definitely works better if you follow good naming conventions and file patterns. And even then I tend to make sure to just include the important files in the context or clue the LLM in during the prompt.

It also depends on what language you use. A LOT. During the day I use LLMs with dotnet and it’s pretty rough compared to when I’m using rails on my side projects. Dotnet requires a lot more prompting and hand holding, both due to its complexity but also due to how much more verbose it is.
