I ran across this fascinating tool a few days ago researching embedding models on hugging face.

Advertised as "ColGREP Semantic code search for your terminal and your coding agents",

I haven't put it in any harness yet but I probably should.

I've also tried astgrep (also known as sg) but llms really mess up on them. I think you'd need to fine tune.

If anyone has cracked that case I'd love to hear about it
