Welcome to Full Stack Friday, serving up the hottest developments for AI builders, hot off the griddle. We've got……….. 10,000+ new stackers since my last send a month ago (!!!)

Welcome to the stack! 🥞 I've got a survey linked below so I can learn more about all you lovely people and what you want to learn.

It's been a month – I've been heads down building my Claude Code: Mastery course, which is now LIVE with 150 students. It's been really fun so far and I'm learning a ton about how to make it even better. More on that below.

This week we’ll look at all the new Claude Code features turning it into agent platform you control from anywhere.

Here's what we're covering:

Let's do this.

Here's a quick reminder of all the free resources and courses in The Full Stack universe. The idea behind all these courses is that you learn the tool IN the tool – so you learn by DOING, not reading or watching. Over 25,000 people have completed them with rave reviews.

Again, all 100% free! I have a lot more stuff coming soon too.

We hit 40K subscribers. Growth has been insane, mostly driven by the Claude Code for Everyone and Claude Code for PMs courses.

This feels like a good time to take a step back to learn who you all are and what you want to learn! So I made a quick survey. Your answers will literally decide what's next. I live to serve.

7 questions, 2 mins, mostly clicks:

Claude Code for PMs: Mastery is LIVE. 150 students in the founding class and it's off to a great start. I'm learning a lot about what works, what to improve, and everything I need to do to scale this to everyone. Applications for the next wave are open now and will start in early May.

I was on Aakash Gupta's Product Growth podcast for my third Claude Code appearance. We went deep on more advanced features that seriously leveled up my own usage: context management, skills, Jupyter notebooks, and my full personal OS.

🔗 Here’s the guide + all the exact files I used in the lesson so you can follow along at home.

Anthropic has continued shipping at breakneck speed, putting out roughly one release every 3 days in March.

Here are the highlights:

March 13: 1M context generally available. So much less compacting! You can now fit entire codebases, full project histories, and months of docs into working memory. Claude also leads on actually USING that context (78.3% recall at 1M tokens vs GPT-5.4's 36.6%). I was personally so grateful for this release since I was hitting the context limit every few prompts when building Mastery.

March 17: Dispatch. You pair your phone with your Mac by scanning a QR code, and then you can text Claude instructions from anywhere. Claude works on your desktop and sends back the results. The conversation thread is persistent, so context carries across your phone and your computer. Claude Coding at the gym has been kind of surreal.

March 20: Channels. Claude Code can now connect directly to Telegram and Discord. Similar to dispatch, but a nicer interface in the chat apps.

March 23: Computer Use. Claude can now see and interact with your actual screen. It opens files, clicks buttons, fills out forms, and navigates between apps on your behalf. When you combine this with Dispatch, the workflow gets really interesting: you text Claude a task from your phone, it operates your computer while you're away, and you come back to the finished result.

March 31: The source code leak. Does this count as shipping? Anthropic accidentally shipped their entire 512K-line codebase. The community dug through it and found 44 unreleased feature flags, including something called KAIROS, which is an always-on mode where Claude runs 24/7 with scheduled tasks, GitHub monitoring, and proactive actions. This is where Claude Code is heading.

April 7: Claude Mythos. Anthropic previewed a new model that sits above Opus in capability. The claims are wild. but they're clearly running the classic "it's too powerful to release!" playbook, so it remains to be seen how good it really is.

As a reminder, this was the headline in 2019 with GPT-2:

Anthropic is really making good on their obvious goal of replicating OpenClaw. They even officially cut off OpenClaw from Claude subscriptions on April 4th.

Claude Code is become a powerful agent you supervise from anywhere. You text it from your phone, it works on your desktop, you come back to results.

Keep in mind, this is just an extension of understanding how to use Claude Code normally. You still need to set things up while sitting in front of the computer, so everything you do to upgrade your Claude Code skills is amplified by these features.

If you haven't started either ccforpms.com or ccforeveryone.com, there's never been a better time. New lessons about these remote features coming soon.

In honor of the likely overhyped Mythos

All the other fun stuff from the last month.

If you haven't done either of my Claude Code courses yet, the second best time to start is today. The tools are getting more powerful every week, and the courses are getting better too.

And please take the survey! It's 2 minutes and it directly shapes what I build next: SURVEY

Keep building,
