An agentic workflow needs a recovery path. We introduced an invalid commit reference, routed the review feedback back to the Developer agent, verified the correction, and then sent the task to human approval. See the case study 👉 clstk.com/4hn7Lgd

Sharing a lot of code does not automatically give you one mobile product. Share the layers whose behavior should stay consistent. Keep platform differences explicit, with owners and tests. React Native at Scale 2026 explains how experienced teams make that call: clstk.com/4xY0cmB

React Native can give teams one shared codebase. Still, it does not decide who owns upgrades, releases, or the shared setup. We combined 10 years of experience with perspectives from 12 organizations in React Native at Scale 2026: clstk.com/4r1ELPt

Registering a native module twice can crash a React Native app. Our Super App Showcase prevents that by keeping native code in the Host Shell. Mini Apps stay JavaScript-only and load when needed with Re.Pack and Module Federation. Read more about it: clstk.com/4gsofo3

People are tired of AI talk for a reason. Too much of it is vague and disconnected from real work. We’re sharpening our livestreams to focus on AI from a developer’s point of view: real workflows, where it saves time, where it adds risk, and where teams still need to slow down and think.👇
