Claude Code adds Concise output style

This is a practical quality-of-life update that targets one of the biggest frustrations with coding agents: excessive narration. It improves signal-to-noise without changing Claude Code’s underlying capabilities.

• –Result-first responses make long coding sessions easier to scan
• –The style reduces conversational overhead without sacrificing requested detail
• –Error reports, security warnings, and destructive-action confirmations should remain fully explicit
• –Because output styles modify the system prompt, the mode affects the whole session rather than one response
• –Developers still need to review code carefully; brevity is not a reliability guarantee
