Claude Code v2.1.72 9 Mar 2026

Brief Mode (Compact Chat View)

What

A new compact view mode that shows only checkpoint messages (from SendUserMessage) instead of the full tool-call transcript, with dedicated visual styling.

Details

Controlled by the CLAUDE_CODE_BRIEF environment variable or the tengu_kairos_brief feature flag
Adds a Brief tool and BRIEF_TOOL_NAME / LEGACY_BRIEF_TOOL_NAME constants
User messages display with a "You" label in blue; Claude's responses use a distinct orange label
When brief-only mode is active, the token usage bar is hidden and the spinner uses a simplified dots animation
Toggle via a new "Toggle brief-only mode" action

Evidence

Brief mode infrastructure (search for "CLAUDE_CODE_BRIEF", "tengu_kairos_brief", "isBriefOnly")

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
