Shipped an update to Design OS today.
Improvements:
- Much faster AI design workflow (without sacrificing steps or quality).
- Optimized the hand-off so that Design OS gives your coding agent the frontend UI layer, less prescriptive on backend.

New behavior I noticed in Claude Code: If I give it a big task, it sometimes enters plan mode on its own and makes a plan. I like it.

First few days impressions of Opus 4.6: Same excellent performance as 4.5.
Most noticeable improvement is it recognizes my intent faster, with fewer iterations to get there. Instead of 4-6 drafts, we get to something shippable in 1-2.

But I get it now. It'll be my first (true) AI employee that plays a real role in our operations.

Many jobs-to-be-done can (and probably should) be built as simple agent skills. It's often better than buying an off-the-shelf SaaS or even vibe-coding your own app. 👀

Writing, like code, is easier to ship now.
Still need original ideas. A point of view. Taste. Voice.
But you don't need to toil over getting the first words on the page anymore. And yes, you can still publish things that are authentically you.

20-min voice memo on my morning walk, speaking my mind on something I noticed this week (about our transition to AI).
Feed the transcript to Claude, which I've trained on my recent writing and voice. Spend an hour with Claude on multiple drafts and refinements.
Touch up the last 5% by hand. Send.

For years I couldn't make a weekly newsletter stick. So many half-baked drafts trashed because I didn't have time to get what I wanted to say into a shippable state.
Now I don't miss a week:

Agent OS v3 is out.
Legacy codebases are a challenge in AI development. Your agents can scan your files, but not the knowledge and decisions baked in between the lines.
Agent OS enhances (doesn't reinvent) what Claude Code does well.

There are so many "one-off" mini-app builds we can just spin up now, on demand.
Instead of a traditional slide deck, why not an interactive presentation as an app?
Instead of a written proposal, why not an interactive pitch + buy button?

Agent OS v3 strips 70% of its codebase and somehow is even more useful now—especially for working in legacy codebases into 2026.

Also added keyboard shortcut to CleanShot's scrolling capture feature for long page screen grabs, which I drop into prompts and specs constantly.

A muscle worth building for better prompts:
Frame your feedback around the end result, goal, or emotion you want to get to, with whatever you're building or creating.
Avoid micro-directing specific changes and how to make them.
