Prompt library
Definition
A prompt library is a versioned, shared collection of tested prompts for recurring tasks, turning individual experimentation into a repeatable organisational capability.
Without one, every person reinvents their own approach and quality varies by whoever happens to be writing. With one, a tested prompt produces consistent output regardless of who runs it, and improvements benefit everyone immediately.
It needs the same discipline as code: version control, a named owner per prompt, documented expected output, and a review when the underlying model changes — because model updates routinely alter how a prompt behaves.
