Once you get to a codebase beyond a certain size, that no longer works.

I've for one found Serena https://github.com/oraios/serena , which you can install from right within Claude, to be a fairly fantastic code-interaction tool for LLM's. Both semantic search as well as editing. And with way less token churn.

This is an interesting one - thanks for sharing!

I actually just enhanced my `codescan` project to exceed Serena in some ways

https://github.com/pmarreck/codescan

Essentially zero-install, no MCP, just tell your agent about its CLI, have Ollama running with a particular embeddings model and boom

now I just need to set up Github Actions (ugh) so people can actually download artifacts

This is definitely a cool finding.

Have you investigated more on this topic? like, anything similar in concept that competes with Serena? if so, have you tested it/them? what are your thoughts?

@pmarreck, Serena developer here. We invite you to contribute to Serena in order to make it better. Serena is free & open-source, and it already robustly addresses the key issues preventing coding agents from being truly efficient even in complex software development projects (while being highly configurable).

We don't believe CLI is the way to go though, because advanced code intelligence simply cannot be spawned on the fly and thus benefits from a stateful process (such as a language server or an IDE instance).
