October has been an absolute nightmare for software > Railway - customer secrets exposure > LiteLLM - malicious PyPI + Docker releases > Zeabur - infrastructure breached > OpenCode - AI API keys exposed > OVHcloud CLI - official binaries backdoored > Rank Math PRO - malware in official plugin > TeamUpdraft - customer data compromised > ConnectWise - cloud backup identities compromised > Tensorlake - npm package infected > SubQuery - backdoored npm package > GhostAction - GitHub repos with malicious workflows > PHP - critical RCE vulnerabilities > Node.js - security vulnerabilities patched > eMudhra - certificate authority keys compromised > Tailscale - eMudhra incident At this point, the biggest security risk might not be the code we write, but the code we trust...

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 Full source available in the comment below πŸ‘‡
Last night, a swarm of Opus 5.5 agents working for 9 hours and burning 254.2 million output tokens were able to fully reverse engineer and decompile the Linux source code Full source archive available here kernel.org Grab it before they take it down

Inspired by @tomekzaw_'s Android <πšƒπšŽπš‘πš> profiling thread, I dug into the iOS side: how <πšƒπšŽπš‘πš> is measured and drawn, and what the <πš…πš’πšŽπš >s around it do when they move or fade ⏱️ Benchmarked with Argent on a physical iPhone πŸ“± 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. πŸ§‘β€πŸ’» We've seen some good results running it internally - give it a try and let us know any feedback! github.com/android/skills/tr…

Who's testing the code your agents write? @SzymonRybczak of @TesterArmy explains AI testing for web and mobile apps, including test plans built around each pull request.

Another cross platform player @DartNativeX πŸ‘‹
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

How can I reach more Python devs on X? I know they have to be here somewhere.

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. incubator.callstack.com/appd…
