You can let the LLM decide how to name things, and spend days or weeks refactoring things. Or you can get your sketchpad out and invent/derive Correct names for methods, api methods, database schema, and so forth, and save yourself a lot of trouble.
The LLM is great at elaboration, but bad at inception, that is, bad at starting off from a blank canvas accurately for a long-lived project. That's where human creativity and genius come in. Not in the elaboration, but in the seedling.
In the orchestration metaphor, it's as if you give the LLM a blurry blob of reality and it starts playing music on it. You clarify, that's a saxaphone, or that's a cello, and suddenly it holds it correctly and plays it with sophistication. If you neglect fair naming or good-naming of your methods and needs, the LLM does its best guess on what this blurry blob of reality is, and it is often a blurry result to accompany.
