Claude Code Shipped a Built-in 'Concise' Output Style in 2.1.237, and Practitioners Say It Will Not Cut Their Token Bill

Anthropic added a Concise output style to Claude Code on August 20 in version 2.1.237, selectable under Output style in /config or settings.json, which leads with the result and skips preamble while doing the work just as thoroughly. The r/ClaudeAI thread asking whether it reduces token consumption drew 219 upvotes and a clear consensus of no: the token cost sits in input context, file reads and reasoning traces, not user-facing output, and one user posted the full system prompt showing it technically adds tokens per request. A separate post noted the new styles are injected as a system-reminder every turn, unlike the older Explanatory and Learning styles.
