Alrighty folks, I've renamed my twitter account from @zephraph to @just_be_dev. Got a placeholder for the old one.

Experimenting with pinned cards and frames on the tabletop

built a real-time writing linter powered by jev 📝 write custom rules like “flag anything that sounds like a linkedin post” receipt printer included 🖨️ (includes audio)

Today we’re launching Worker Previews. Each Git branch gets a production-like place to run, with its own code, configuration, URL, observability, and state. cfl.re/4hgSuxf

Powermove is out today. It's a video editor where the app itself is the thing you edit. The kernel is intentionally tiny. Timeline, effects, inspector, the UI, all of it lives in extensions on top. Ask the Powermove agent for a feature and it writes an extension, the same way we built the rest of the editor. After Effects won because of twenty years of plugins. We're trying to compress that into a prompt. Free, open source, by Iterative Computer.

Introducing Enzyme: a language for teaching agents what to notice in your Markdown wiki. You declare how different parts of a knowledge base should be read. Enzyme compiles that lens into questions your agent can use to find the right sources. You keep talking to your agent normally.

You can now define evaluations with Jev.

Jev (and fast/cheap generalized classifiers) can make AI qualitative linters actually useable! Imagine defining free form rules to be checked at specific granularities

Inspired by @typesafeai , here is a Jev-compatible public API to play with It runs a comparable open model (Qwen3.6-35B-A3B), and just uses SGLang radix cache to preserve the prefill reuse / really fast parallel systemone generation - 64 tasks in <1s. github.com/ekzhang/openjev-s…

This version marks our first step towards "software factory components as Effects & Layers" with an embeddable Git Service. In our benchmarks, it was typically faster than GitHub and I've already got a private prototype with Issues and Pull Requests.

Build a feature with an agent, have another agent review it, then bring in your teammates to approve the change. Agents and teammates, working together in Delta.

New Decision abstraction now live in effect-agent. Jev is obviously the only provider for this right now.

Playing with @zeddotdev's delta today (delta.dev). I'm very excited about this.

Workers traces now include RPC spans for Worker-to-Worker and Worker-to-Durable Object calls 🚀 VERY excited by this ship, anyone with traces enabled gets this automatically + anyone who wants it can enable with one line of config!

Delta is now in public beta. It’s a multiplayer environment for coding with agents and reviewing what they build, with every code change linked to the conversation that produced it. Anyone can download it today on macOS, Linux, and Windows: delta.dev/download

I've been playing around with Jev in effect-agent and so I built a simple effect service for it. This model is super awesome by the way!

✍️ Playing with programmable highlighters, e.g. * green highlight on a citation -> finds and prints the cited paper * orange highlight on a claim -> prints a skeptical fact-check Extends naturally to "if I write a comment like 'Is there more recent work?' and circle it in purple, send the comment with surrounding context to an agent"

Four ornamental lettersets are now available as drop caps in the Alembic editor—all vectorized from real books c. 1510–1900! alembic.space/editor

If you're not familiar with Austin's work, he's designed some of the most fun software of the last 2 decades…

Introducing shadcn/lint. An agent-first linter for Tailwind design systems. You define what’s allowed. When an agent breaks a rule, the error explains what’s wrong and how to fix it using your components, variants and theme. There’s a lot you can do with this. Let me show you ↓ github.com/shadcn-ui/lint

Working on a blogpost for my React parent/owner tree visual notation & dev tool. Now getting to displaying React Server Components, The server/client boundary follows the owner tree, and I think these diagrams make that visible
