I see no one has referenced the written by ai paper itself https://arxiv.org/abs/2608.13568 https://github.com/agentconnect-md/lsp-vs-grep-token-study The author uses their own harness, I'd want to see if what they are seeing is related to the harness, they should at the minimum also use CC which has direct LSP support. Their metric is token economy, many of us don't pay per token and capability in terms of difficulty and quality are a more important metrics for the kinds of work I do. I'd want those tested as well.
