concise

This word carries a strong positive connotation of efficiency and mastery. It describes a style where every word earns its place, removing fluff without sacrificing the core message. It is the gold standard for professional writing and technical documentation. In contrast to "brief," which simply means short, "concise" implies a high density of value. A brief message might be too short to be useful, but a concise message is perfectly calibrated to be as short as possible while remaining complete.
