NEW VIDEO: How Senior Engineers Actually Build with AI in 2026 | Build a Full Stack Job Applications Platform 🚀
I built JobPilot - a full-stack AI agent that automates the job hunt - in just a few days without writing a single line of code by hand.
By the end of this video, you'll have built it, too.
✅ Finds jobs, then scores them against your profile.
✅ Deploys real browsers across the web to deeply research the company behind the listing.
✅ Automatically writes your cover letter and tailors your resume to match.
But honestly, the app itself isn't even the best part.
The real value is in the five open-source agent skills I'm giving away:
1️⃣ /architect
2️⃣ /review
3️⃣ /imprint
4️⃣ /recover
5️⃣ /remember
These give your AI agent memory, focus, and the ability to actually ship a project without drifting off course.
That's the actual skill. And it's completely learnable.
You can install them once and use them on literally every project you build moving forward.
Here is the stack we are using to make this project happen:
→ @nextjs 16
→ Backend: @insforge
→ Real browser automation: @browserbase & @Stagehanddev
→ Intelligence: GPT-4o
→ Analytics: @posthog
If you know basic #JavaScript, you can follow along.
By the end of this tutorial, you won't just have a working AI agent - you'll have a system for building anything.
(A system that doesn't get replaced by the next model, but instead gets stronger every time you use it.)

Couldn’t @AnthropicAI just reship Fable as say, “Muse” and be done with it?
Just label it “general purpose,” position it as being for basic everyday needs, avoid the “dangerous” tag, and ship it 🙃

Just when I wanted to make a video on Claude Fable 5, Fable became a fable 🫠
Jun 13
The US government, citing national security authorities, has issued an export control directive to suspend all access to Fable 5 and Mythos 5 by any foreign national, whether inside or outside the United States, including foreign national Anthropic employees.
The net effect of this order is that we must abruptly disable Fable 5 and Mythos 5 for all our customers to ensure compliance.
Access to all other Claude models is not affected.
We apologize for this disruption to our customers. We believe this is a misunderstanding and are working to restore access as soon as possible.

Quiet morning for new AI tools... buuut WWDC26 starts tonight, so that may change very quickly
I’ll be watching for the features developers can actually test and build with, not just the keynote headlines.
Let’s see if Apple is still behind or if they've been working on something that actually makes sense

I tested @ChatGPTapp Codex remote control on Mac mobile.
Codex keeps working on your Mac, but when it needs permission to continue, you can review the request and tap Allow directly from your phone.
It is genuinely useful when you step away from your desk.
I am casually approving coding tasks from my phone now.
Insane world we are living in.

Go check your 'Forgot password' endpoint right now.
If it has no rate limiting and no bot detection, it's wide open - a massive security liability. @arcjet

"Do the skills I spent YEARS building still matter?"
Every developer I know is quietly asking the same thing.
It's a fair question.
AI writes better code every month.
The gap between junior and senior is closing.
But there’s more to this story than meets the eye.
It’s incredibly easy to open Claude, generate an impressive script, and flex it on X.
But try maintaining that AI-generated spaghetti by the third feature.
It’s impossible.
You see, AI doesn't make developers less valuable.
It just makes the gap between developers with a system and developers without one, larger than it's ever been.
Because anyone can open Claude and get code out.
What almost no one figures out is how to give the agent enough context, structure, and direction to build something that holds together.
That's the actual skill.
And it's completely learnable!
In the next JavaScript Mastery YouTube tutorial, I’m going to teach you exactly THIS.
Because, if your value is understanding how systems fit together...
... you are about to become more powerful than ever.

1/ One-Minute Security Audit: Does your login page have rate limiting?
If the answer is no, your users' data is at risk. 🧵👇

6/ So, how do you stop it?
With @arcjet, it takes just a few lines of code.

7/ Before:
No detection. One lucky match = full account access.
After:
Bots caught. Attack patterns shut down automatically.
Your login page now fights back!
