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.

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

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: https://t.co/w0VgvPYLJ3

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.

Tweaked workflow: Figma as a canvas and prompt reference, Claude CLI for coordinating, and Xcode for building. Figma's MCP removes the need to export designs and create complex prompts, with Claude simply pulling layer names, spacing, etc. Opus 4.5 performed better outside

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:

Introduced a 10-year-old to @v0 over the holidays. He immediately started one-shotting asteroid games and his mom couldn’t quite grok that Vercel wasn’t a gaming platform like Roblox. Reminded me of discovering Photoshop in middle school. Except his canvas is boundless.

I met some of my closest friends at @Epicurrence years ago and @forum_tokyo is shaping up to be a similarly small and stacked crew. Hoping to help others have an equally formative and career defining experience this Feb.

"My worry isn’t the code or the tools themselves. It’s a decline in consideration, and with that, a decline in unique, well-designed products. The question is how we keep that alive even as new tools and technologies emerge." @karrisaarinen https://t.co/sRId2waO8K

I started out as a design engineer. The blind spot I had was that I designed what I could build and struggled to think of solutions outside that constraint. As tools-based constraints shift, it’s hard to imagine implemented quality won’t rise but I suspect there is a risk we’ll

I set a goal to host 12 events this year. 11 down, 1 to go. Through those parties, I met my now-girlfriend, formed business partnerships I’m working with today, and built muscle memory such that I can both host and be fully present with people (harder than it looks). Would

Modern people have lost the art of hosting, being a community member, and inconveniencing themselves. Throw the party. Host your relatives. Ask the person on a date. Treat your friends to dinner. Learn to cook for others. Meet your neighbors. Talk to the person at the grocery
