Building something new. Led Design & Research @Coinbase, design systems @Airbnb, and teams @Facebook

linting agent PRs is standard today. doing so for design quality in those PRs is a logical next step. curious how designers are already doing something like this today
engineering is moving 10x faster. design review hasn't caught up. introducing Impeccable ..for PRs! a design review agent that simulates your users, uses your app, finds friction & slop. Impeccable’s design judgment in every PR. reply if you want in on the closed beta 👀

Never touched Hearthstone but the game mechanics, creation flow (with @NotionHQ driving the illustration pipeline), and the animations and performance for a project created over a weekend spark joy
As a Hearthstone Enjoyer, this is pure catnip. The card pack design alone, ayah 😍 Also I hope Gabe will show some of the bigbrain automations he set up behind the scenes to build this project...truly a Generational Vibe Coder Of Our Generations Vibe Coders. And finally, if you get my card in your pack, just know that it's basically the most OP insta-win pull possible and you will win every match no matter what.

Wasn’t on my bingo card
Midjourney is acquiring Co-Star. CEO @banu__guler is now Chief Design Officer at Midjourney. She's building a cross-functional design, product and frontend team for all our efforts. The Co-Star app will continue to operate under Banus complete control. Welcome Banu and team <3

Now that Instagram is more about Reels than photos, I no longer have one place to see the world through my friends' eyes. Instead, many of them have started posting photo journals on their own websites. So @charliedeets and I teamed up again to build Openfeed. It pulls photos from personal sites and brings them into a single curated feed.

Packed house at design tools demo night at @spc with @amberlikescode @maayanalbert @fredzaw @arjmahesh @Flomerboy and a cameo from an alien sharing what it’s like to design for an agent-based OS (Claude)

NYC’s tech scene strikingly robust at Ship today, especially compared to what it was a decade ago thanks for the invite @soleio and great meeting @jameygannon and @tomocchino

As much as I love my OpenClaw, Patina has been a joy to use. Can't wait to see where Patina goes from here. Congrats @gabrielvaldivia!
I've spent the last few months building Patina: a personal intelligence workspace that lives on your Mac. It reads your iMessages, calendar, email and more. Knows your goals and helps you keep up with your people. All stored locally. 🌐👉 patina.md/

In a recent batch talk, YC General Partner @t_blom broke down how to build a self-improving, AI-native company. He walks through how to create recursive, self-improving AI loops, and why founders who get this right will run companies that improve while they sleep. 00:00 — Companies Are Roman Legions 00:54 — Copilots Are the Wrong Mental Model 01:55 — Extract the Domain Knowledge 02:24 — The Recursive Self-Improving Loop 04:12 — The Holy Shit Moment at YC 05:50 — Self-Optimizing Product and Support Loops 06:29 — Burn Tokens, Not Headcount 07:23 — Middle Management Is Over 08:05 — Make Everything Legible to AI 09:40 — Regenerating the YC User Manual 11:19 — Software Is Ephemeral, Context Is Valuable 12:18 — Where Humans Still Matter

woke up and my mentions are full of these Both me and @davemorin tried to talk sense into Anthropic, best we managed was delaying this for a week. Funny how timings match up, first they copy some popular features into their closed harness, then they lock out open source.

I will argue that the culprit is timing and substrate instability more than design or anything else. We have simply not had successful consumer AI companies (besides OpenAI and maybe Claude - not Claude Code). - Inference cost - Jagged intelligence - Rapidly changing frontier - Free ChatGPT good enough for most normies Intelligence is a new medium. Even there memory, personality, persistence, agent agency, long term planning are not really solved. I have yet to see an agent harness/scaffolding that survives 6 months. Every new model makes half the bells and whistles unnecessary. New model capabilities gave a shelf life of a few months before Open Source catches up. You can’t design great consumer UX on a platform that’s still being invented underneath you. The tech has not settled yet for masses. Even early adopters can’t keep up. Things that have won are those that we had priors for - Chatbots, Coding. Also don’t think designing for pixels is dead. We are very visual creatures. The shape of what we call “UI” needs to evolve along with a few computing constructs. The shape of the container of intelligence will be varied and hyper personal. We are in very very early innings. This is not the iPhone moment. This is pre-Macintosh moment.
i have one upsetting observation: all the beautifully designed AI tools we’ve seen so far (dot, humane, cobot) were basically dead on arrival, while complex, highly technical products (claude code, openclaw) gain mass adoption in seconds. we're definitely missing something.

Annotation > prompts
Meet InterfaceKit, a design tool for working with agents. Refine components live in your app → click to copy prompt. Your agent gets the element data, Tailwind classes, and Motion animations it needs to make your changes in one shot. No more guess and check.

Fun design detail: @conductor_build's "cities" (workspaces) you've visited. A lot to like about this product.
Replying to @j_smith
Two tools that I’ve come to love: @usemonologue. More whimsy, less UI, and great dictation. @conductor_build — the team is cooking! Tried it months ago, came back, and barely recognized its thoughtful git worktree integration and opinionated UI. Paired with @linear, each ticket becomes context for a fresh agent in a new worktree. Suggestions on how to set up for Ralph, lmk

Opens Figma MCP: "… keep looping until you can't find any differences" Great tips in here
Give your agent a laboratory, not a task — this is the #1 way I've found to get coding agents to do better work: brianlovin.com/writing/give-…

Built an iOS app to track my 2026 daily goals. Used it as an excuse to switch up my workflow (Claude CLI + Figma MCP + Conductor instead of Cursor) and play around with some novel interaction patterns and sound design. Some learnings:

Building personal software is very freeing. Vertical nav? Sure. Quirky animations? You call the shots. And I finally got to use Facebook's SoundKit. I worked with @Wavegroupwill to ship it almost a decade ago but never put it to use until now.
