Making progress on an open-source library where you author agent logic as state machines in XState and run it *anywhere*: Mastra, Eve, Flue, Vercel AI SDK, Cloudflare Agents, or your own runtime. It’s coming along!

XState v5 is finally here 🚀 → Express any logic, from promises to state machines → Much simpler API → Massively improved TypeScript experience → Smaller bundle size, zero deps → Advanced statechart features → New docs, examples++ npm i xstate

Just discovered that you can enable tab-completions for npm commands pretty easily. Wish I did this years ago 🤯 npm completion >> ~/.bashrc npm completion >> ~/.zshrc

Ever wanted to actually *simulate* your Mermaid state diagrams to see if the logic makes sense? Yeah, me too. Just copy-paste it into Stately Sketch and press play. Should I add a Mermaid → Code converter? 🤔

One underrated benefit of declarative, event-based state management: It turns your app logic into something LLMs can use *directly*. Transitions + schemas become tool calls automatically. The agent doesn’t mutate state; it sends events the app already understands.
