And yes, it's another reason why I like state machines: you can effectively prototype the behavior, write a spec, and implement it *at the same time*
Stop sleeping on state machines

New Electric Agents RFC: Signals
UNIX figured out 50 years ago how to handle long-lived processes. So we ported UNIX signals to Agents.

Introducing Electric Agents!
Agents are not compute. Agents are data. Multi-agent is a sync problem. Electric Agents is the first agent platform built on sync.
Use it to build scalable, collaborative, long-lived multi-agent systems: 🧵👇

Every JWT writeup online covers 2–3 attacks and stops.
I got tired of jumping between 40 blog posts, so I wrote the whole thing. All in one place.

👷 Kami is now open source. Your AI writes well. Now your docs can look good too.
A design system for AI-native docs: one-pagers, resumes, portfolios, letters, long docs, and slides. Bilingual, diagram-ready, print-ready. Zero setup.

Turns out React can handle massive diffs (200k ) and huge conversations just fine — as long as you give it a strong measurement layer underneath. Shoutout Pretext from @_chenglou. Smooth as butter ✨
- Custom virtualization
- Sync tokenization with Shiki for syntax highlighting

Today, we're joining Google's release of A2UI v0.9 🎉
Declarative Generative UI with your own design system.
Works with any AG-UI Agent.
Your agents describes UI via JSON, your frontend renders it using your components catalog like lego building blocks
UI is alive and dead. CLI for agents, Generative UI for humans.
Try it out:
npx copilotkit@latest create my-app --framework a2ui

Released the XState v5 skill 🚀
The goal isn't just "know the API" but rather "help agents make really good state machines"
Tuned & tested against real examples, common anti-patterns, and the mistakes* LLMs tend to make with XState
npx skills add statelyai/skills

middle truncation
- a11y
- text selection copy preserved (doesn't copy the ellipsis)
- no ellipsis gap
- preserves the meaningful start end based on content (file paths, subdomains, branch names, ai model provider/name)

3 months ago I started building a coding agent that runs in the cloud.
It's since written every line of code I've shipped, including itself.
Today, I'm open sourcing it. Introducing Open Agents.

The tools have changed, the web has changed, and my thinking on several fundamentals has evolved. This is the Astro version:

Here’s how we use Codex to:
> understand large codebases
> review PRs faster
> build macOS apps
> turn Figma into code
> automate bug triage
> create a CLI as agent tools
> analyze datasets
> generate slide decks
> coordinate new-hire onboarding
> learn a new concept
…and more.
developers.openai.com/codex/…
@kagigz , @Dimillian , @nickbaumann_ and team pulled together a great collection of Codex use cases, and based on how engineering *AND* non-engineering teams build with Codex daily at OpenAI.
What else should we cover?

agent-browser Lightpanda batch multi-session is a dangerous combo
Completed this benchmark task in 5.85s

alright agent nerds, if you care about your tokens and usage limits, pay attention to the tools you give to your agents.
i built a benchmark that compared various browser tools for agents, and here's an example of their massive difference in cost and latency doing the same task

Add max lines and max cyclomatic complexity rules to your linter. The code will be much, much better.
There are additional things like forbidding using ??/?. on non-nullable props, as GPT seem to know that TS would allow this shit to happen.

Use a hook. Here’s an example:

Codex just dropped Hooks in the latest release - so I built a tiny macOS toolbar app, Loopndroll, that makes sure your Codex Agent never stops working.
It’s open source. Link below.

Yup. The core insight from Pretext is that layout as pure arithmetic unlocks a whole category of real time UIs that were structurally impossible with DOM measurement. Dashboards, editors, virtualized feeds.
Anyone building data heavy frontends should look at what @_chenglou built.
