Generally it is recommended that you fine-tune if you want to shape the output style. If you eant ro only output json, or just output jsdoc, etc. To add knowledge, RAG is a better idea and easier to keep updated on code changes. If rag does not give back good results then that's a problem with the retrieval part, which can be measured and improved. We're building documentation + rag systems for enterprise code bases and this is what we saw works best.
