shipping for GA really just been like

[Alex Shan @alexshander03]

Today, @JudgmentLabs opens for general access.

We believe long running agent systems will generate more exhaust data than the world can currently process.

Hidden within agent traces are rich records of how to make these systems better: what users ask for, when agents stumble, and how agents interact with the external world.

Judgment is the most performant monitoring and improvement layer for long-horizon agents.

We’re excited to see what you build!

[AI SDK @aisdk]

Introducing Web Fetch Tool for AI SDK.

Let your agents read any web page, with any model.

[sean @seancfong]

as somebody who's already migrated over to dia, this is still disappointing to hear

[Arc @arcinternet]

We've decided to sunset Arc on December 22, 2026.

That's not an easy sentence to write. We spent years building Arc and celebrating each and every release along the way: we have so much pride and love for what we made alongside the Arc community.

Our priority is to deliver best-in-class security for our members. Keeping a browser secure takes constant, dedicated work that is only increasing in the age of AI. Dia was built from the ground up to meet today’s security standards, so that's where our engineering and security teams will focus moving forward.

We've worked to make switching to @diabrowser as easy as possible for Arc members. Here's how:

· Your passwords, bookmarks, extensions and history come over to Dia seamlessly.
· Spaces, Folders, and Tab Groups are in Dia and import over with your data intact.
· Dia now surpasses Arc benchmarks in stability, speed, and security.
· The browser features you use in Arc are free in Dia, and the AI is optional.

Thank you for using Arc, for pushing us to make it better, and for building alongside us. The team that made Arc is the same team behind Dia, and some of our most ambitious work is just ahead. We'd love for you to be there with us when it lands.

[sean @seancfong]

this is the kinda stuff teams should be building instead of relying on slop unit test suites

[Jakub Krehel @jakubkrehel]

I added a new /state-machine skill to the collection.

It renders any component you want in all of its states on a throwaway page with mock data.

I enjoy working like this a lot. It makes it very easy to work on more complex components.

i remember the pain of manually building something like this way back in the day

agents & open source software are truly exceptional
