Can you offer any insights how this compares to building an AST or RAG over your codebase? Several projects do that and it autoupdates on changes too. The agent does a wide sweep using AST/RAG search followed by drill down using an LSP. This sped up my search phase by 50%. How Will this project help me?

I think it's a great idea and I'm considering building this in lat too. Code embedding models can definitely speed up grepping further, but they still wouldn't help much when you have a business logic detail encoded across multiple complex files. With lat you'd have it documented in a paragraph of text + a few [[..]] links into your code.
