I guess this is as good a place to ask this as any. Is there any good tooling for integrating LLMs into classic Unix developer workflows? So not an IDE plugin, not a new IDE, not copy-pasting code into chatbots, but something that composes with the command line and arbitrary editors. Basically, what I'd like is to never copy-paste code to/from the LLM but for it to happen automatically when I ask the LLM a change. And I'd like an interaction model where all the changes are applied directly to the workspace and then use whatever tools I like to review them before committing. (But I guess anything that achieves the same effect would be fine as well, e.g. the changes being automatically git-committed in which case the outcome of a failed code review is a revert, or for the changes being provided as a unified diff.)
