Less like a carpenter using a hammer and more like a Sorcerer's Apprentice using brooms. Your give them instructions, and they mostly take it from there. Hopefully your understanding of those instructions aligns with theirs, and hopefully when it starts to diverge you'll know how to course correct.
Hat der alte Hexenmeister
Sich doch einmal wegbegeben!
Und nun sollen seine Geister
Auch nach meinem Willen leben.
Seine Wort’ und Werke
Merkt’ ich und den Brauch,
Und mit Geistesstärke
Tu’ ich Wunder auch.

I like Goethe's German. In general, German does not feel very song-songy to me, but Goethe wrote some really good and catchy poetry.
