Ask HN: Simple tooling for local LLM code critique without IDE integration?

While I'll set out the criteria for what I'm looking for, I don't want this to turn into a general debate about the role of LLMs in software development. That discussion is important, but we have plenty of them. Consider everything that follows as personal a taste as ice cream flavor.

Is there a lightweight, simple toolset for having local LLMs (preferably through llama.cpp) inspect and critique code without relying on IDE integration? I do not want an LLM to write any code for me, but I have definitely warmed to the idea of having them critique and assist in debugging. I'm a bit of a simpleton who prefers not to integrate too many things with my editor, so I'd like something that behaves kind of like a REPL; some commands to load source files from a directory and present those to the LLM (through llama.cpp?), and then some functions to interact with the LLM with said code in context. With simple convenience functions that let me save state, refresh updated code, etc.

I'd prefer if this didn't all go through the web browser.

Does anyone know of such tooling?
