For most things I approach it from both sides: I give an English prompt but also provide some interface, function signatures, or even just a return type that constrains the LLMs output. For example, I frequently have to implement Serde's traits for some serialization format or to marshal types, most recently to translate types from Rust to Qt QML's Javascript. By giving it some context (Serde traits and QT docs) I managed to do it with Claude in about an hour, which is roughly how long it would have taken me just to get up to date with the documentation if I had tried it myself.
