The Hierophant
"Best Practices"
Major Arcana▲ Upright +1
The ancient wisdom of the engineering blog post, the style guide, the RFC. Best Practices appear as a reminder that other people have solved this exact problem and wrote it up so you wouldn't have to suffer through it yourself. Follow the established path. It exists for a reason.
▽ Reversed -1
"We've always done it this way" spoken in a tone that discourages further questions. The Hierophant reversed is cargo-cult engineering: following rituals whose original purpose has been forgotten. Someone is about to reinvent the wheel, badly, because they distrust the existing wheel.
