Code extraction maybe, not something we have tested or built for but you could give it a try.

Code manipulation probably not since it's a lot smaller of a model compared to a Claude Opus which is SOTA for code generation/manipulation.

Generally code generation is a non-deterministic task by nature and general LLMs tend to be better at them.

The idea of what to change is perhaps an llm task but the job of doing the find replace and that kind of tooling is something LLMs actually struggle with and have all kinds or crutches and try retry loops to paste over in coding agents etc.
