Claude Code v2.1.187–198: Chrome GA, /rewind, Background Agent Auto-PR, and Sandbox Security

What's new

• Claude in Chrome (GA): Chrome extension is now generally available — Claude works directly in the browser.
• /rewind command: restores conversation from before the last /clear — lifesaver when context is accidentally wiped.
• Background agent auto-PR: background agents now automatically commit changes, push, and open draft PRs upon task completion.
• agent_needs_input / agent_completed hooks: notifications on key agent events.
• /dataviz skill: new built-in skill for chart and dashboard design.
• Sandbox security: sandbox.credentials blocks sandboxed commands from accessing credential files and secret env variables.
• Org model controls: organizations set default model configurations enforced across teams; applies to --model flag and ANTHROPIC_MODEL env var.
• 37% CPU reduction: text updates coalesced into 100ms batches.

Why it matters

The combination of auto-PR and /rewind significantly tightens the agentic development loop. Sandbox security is a step toward safely deploying Claude Code in shared enterprise environments.
