Claude Code v2.1.221 Adds a Focus View That Hides Tool Activity, Plus a prompt-audit Subcommand for Stale Prompts
Anthropic shipped Claude Code v2.1.221 on 2026-08-04. The headline for heavy users is VSCode Focus view — a chat-menu toggle (Ctrl+Alt+F) that collapses tool activity behind an expandable per-turn summary with a live running-tool indicator, which is the first real answer to transcript noise in long agent sessions. Also added: a `prompt-audit` subcommand to the `claude-api` skill that scans prompts and tool descriptions for patterns written for older models, a `mode: "mask"` option for credential files on copy, re-enabled tool search on Google Vertex AI for Claude 4.5-generation and newer, and cache-efficient permission checks for parallel tool calls. The prompt-audit tool is the underrated one — most teams still carry prompt scaffolding tuned for models two generations back.
