Claude Code 2.1.63 dropped with a new built-in command: /simplify

It reviews your changed code for three things:

- Reuse opportunities (duplicated logic, extractable patterns)
- Code quality (readability, naming, structure)
- Efficiency (unnecessary complexity, redundant operations)

Then it actually fixes what it finds. Not just suggestions, it edits.

How to use it:
1. Make your code changes as usual
2. Run /simplify
3. It analyzes your diff, finds issues, and applies fixes

In the video I ran it after finishing a PR review and noticed it spawned 3 parallel agents using Haiku 4.5 to do the analysis... fast and cheap

Try it out 👇

Readout is a fully native macOS app I’ve been building for myself. It provides a real-time overview of your dev environment and Claude Code config. All local, no account required. It's still very much a beta, but now available to try: https://t.co/gpKj1KCpcM

In the next version of Claude Code..

We're introducing two new Skills: /simplify and /batch. I have been using both daily, and am excited to share them with everyone.

Combined, these kills automate much of the work it used to take to (1) shepherd a pull request to production and (2) perform straightforward, parallelizable code migrations.

Claude Code pro tip:

Download the Claude desktop app. There is a new Code section

In this section you can literally spin up cloud AI agents that do work for you while you sleep

Every night before you go to bed, kick off 3 small tasks in it

They can be incredibly small, even just tiny visual changes

2 awesome things will happen if you do this consistently:

1. Your app will get 1% better every night while you sleep
2. You'll force yourself to flex your ideation muscle every day. Eventually you'll naturally come up with WAY more ideas throughout the day

Ideation is 100% a muscle. The more you use it, the better it gets.

Also, limits are 2x this next week, so you have no reason to not abuse the hell out of this feature!

Do this every night for the next week, I promise you'll turn into an AI building machine

La structure d'une Landing Page SaaS qui convertit

[Kieran Klaassen @kieranklaassen]

Pro tip for Claude Code: Add this line to your system prompt:

"Your context window will be automatically compacted as it approaches its limit. Never stop tasks early due to token budget concerns. Always complete tasks fully, even if the end of your budget is approaching."

Claude's context awareness makes it conservative about finishing tasks. This prompt unlocks persistent, autonomous execution across unlimited context.
