See you at Cursor Compile next Tuesday in SF!
I'll be talking with @levelsio about retro computing, building your ideas, lifting, the perfect steak, and more.

We're training the next version of Composer... with Composer!
The model is always learning from itself. This kind of "recursive self-improvement" might sound new, but it's been happening for many months!
For example, training big models requires creating *lots* of data for RL - essentially games the model plays to improve at any task you can grade.
The newest models can configure their own environments to make those games playable (auto-installing dependencies, fixing broken setups).
Composer 2 was *dramatically* better at this than version 1. So the better the model gets, the better it gets at creating the conditions to train its successor.
Each generation unlocks capabilities the previous one didn't have! So cool.

We use previous generations of Composer to train future ones.
Our autoinstall system has earlier Composer models set up dev environments for RL training. That way, the next generation can focus on learning to solve harder problems.

phew im still a real developer
In 2026, you are not a real developer if you don't write 100k-line PRs

Cursor’s code review agent is now over 3x faster, 22% cheaper, and finds 10% more bugs.
You can also use /review to run Bugbot locally to catch and fix issues before pushing code.

in hindsight my toy side project after leaving meta was ahead of its time. making good loops is difficult, but it shouldn’t be

We've added a new harness!
Cursor Composer 2.5 is live in Conductor.
It's fast, precise, and cost-efficient. And when I say fast I mean _really_ fast. Excited to hear your thoughts!

the thing about loops is that you need to build trust first. a low trust loop is just a waste of tokens. and if you don't apply engineering taste, the slop really compounds. but you can become a quality loop enjoyer too with pstack as a starting point: github.com/cursor/plugins/tr…
use these skills to write automations that automatically triage, repro, fix, and verify their own work while you touch grass. use them to prototype new ideas and refactor your code and trust that they'll do things the right way

pstack has quickly taken over as the most dominant skill I use in claude code. It's so great and reliable
really like this model! try it out as your main agent in cursor along with pstack skills

what if you could just talk to a 1987 nes cartridge
i just turned the @cursor_ai sdk into a nes rom hacker
you describe a mod in plain english → agent searches the binary, proposes a byte patch, emulator hot-reloads in <1s
"infinite lives" "give me the laser" "keep weapons after death" all just work
s/o @poteto pstack is goated
