Last night @apex__ai agents working for 8 hours and burning 300 million output tokens were able to fully reverse engineer and decompile the @reactnative codebase

Inspired by @tomekzaw_'s Android <𝚃𝚎𝚡𝚝> profiling thread, I dug into the iOS side: how <𝚃𝚎𝚡𝚝> is measured and drawn, and what the <𝚅𝚒𝚎𝚠>s around it do when they move or fade ⏱️
Benchmarked with Argent on a physical iPhone 📱
So far, 4 PRs 🧵
Great article from @incident_io on testing apps in the cloud with agents.
Nice insights and explanations on tunneling simulator access from a lightweight VM.
Powered by @agent_device and @expo infrastructure!
So, @agent_device reached 1M downloads recently. That's what happens when you track it regularly. Cool use case btw for Codex pages - regularly updated dashboard!

We've just released a new official Android skill that can be used to statically analyse your #JetpackCompose code for performance improvements. ⚡️
Install it, and ask your agent to run the skill on your code. 🧑💻
We've seen some good results running it internally - give it a try and let us know any feedback!

I have so much fun shipping this project to you, learning new things every day. hope you find it helpful
Another cross platform player @DartNativeX 👋
Another player in the cross platform world: PythonNative. So far we have:
@reactnative
@NativeScript
@nativephp
RubyNative
I love the way React started this whole trend

Appduct now runs in Flutter apps and in web pages.
Flutter: flutter pub add appduct
Web, any framework: npm install @appduct/web
Register a function, your agent calls it over MCP.

YAML tests are passé. Migrate it to e2e for better agentic support
Thank you, @o_kwasniewski, for your hard work 💪
If you haven’t tried this yet, you definitely should!
Introducing e2e
The agentic testing framework for any app
~/ npx e2e init
→ Fully Open Source
→ Mix deterministic and agentic APIs
→ Supports web, mobile, and more
→ Bring your own agent and infrastructure
→ Run locally or in CI

We are releasing React Native Skia version 3.0 which runs WebGPU by default. By moving away from the OpenGL-centric design, it allows for multithreading by default as well as deep integration with three.js, vision camera, and transformer.js
