Anthropic Claude Code engineer:
"If you're watching Claude write code, you're the QA tester. That's not what you're paid for."
In 37 minutes he lays out how to get your keyboard out of the hot path entirely.
The shift is /loop. You tell Claude to wake up every 10 minutes and babysit your PRs, and it just does it, while you're nowhere near the laptop.
Routines do the same in the cloud, so the work keeps running with your machine closed.
He caps it with remote control: any session, on any surface, driven from your phone.
Watch the full talk, then grab the setup below.
I've been a backend Engineer for 12+ years. Today, I'm a Principal Engineer at Atlassian.
I've designed systems that handle millions of requests. Sat on both sides of system design interviews.
Reviewed more architecture docs than I can count.
Starting today, I'm breaking down the fundamentals of scaling for the next 25 days.
If you're learning system design bookmark this thread, you're going to get a lot of learning from this.
Citadel fired their best quant. He rebuilt their entire algo with Claude Fable 5 in 48 hours - and he's up $430,000 trading it against them.
He didn't take a single file. He didn't need to - ten years of that logic lived in his head, and you can't raid a memory.

Here's the engine MiroFish runs - and it's rigged in his favor. Picture a Galton board: a ball dropping through eight rows of pegs, bouncing left or right at random.
One ball is chaos. Thousands of balls always fall into the same bell curve. That's the law he weaponized.
Every ball is one trade. Each row is a volatility gate - news, liquidations, order-book flow, things nobody controls.
On a fair board every gate is a 50/50 coin flip. His model tilts each one to 0.54 - four cents of edge that only shows up when fair value splits from the book.
Four cents sounds like nothing.
Compound it through eight gates, thirty-two thousand times, and the whole bell shifts right of breakeven: 71% of trades land green.
$93 of edge per trade. $430k across the distance.
Watch the win rate converge in real time - it swings between 50 and 85% for the first few dozen trades, then locks on 0.71 and never leaves.
He doesn't predict a single trade. One trade is a coin flip. Eighteen thousand is mathematics.
They thought firing him protected the edge. They just handed it a grudge.

Introducing Claude Fable 5: a Mythos-class model that weโve made safe for general use.
Its capabilities exceed those of any model weโve ever made generally available.
