It’s been a big week for Claude Code.

We launched 8 exciting new features to help devs build faster and smarter.

Here's a roundup of everything we released: 1/ Extended thinking

Ask Claude Code to “think” to trigger extended thinking, powered by Claude 3.7 Sonnet. Great for larger tasks that require planning, like refactors.

Another batch of features for Claude Code!

Up first: Vim mode. This gives you the familiar insert/command modes for editing your prompts in Claude Code. Turn it on by typing the slash command /vim.

But that's not all: Custom slash commands. You can create personalized workflows that can be invoked anytime as slash commands.

Make them by adding Markdown files to your .claude/commands/ or ~/.claude/commands/ directories. The contents of those files will become new commands.

We've just shipped a new feature in Claude Code: extended thinking. You can simply ask Claude to “think”, “think more”, or “think harder” and it’ll show its extended thinking process.

This is all powered by our hybrid reasoning model, Claude 3.7 Sonnet. Best practice: First tell Claude about your task and let it gather context from your project. Then, ask it to “think” to create a plan.

Claude will think more based on the words you use. For example, “think hard” will trigger more extended thinking than saying “think” alone.
