my new favourite way to design with AI

Sorry the newsletter is so late guys.
It’s somehow crept from a Thursday newsletter into a Monday or Tuesday newsletter, entirely due to my poor time management lol.
My second episode with Greg Isenberg is also out!!
We broke down how I use skills, plus the system I built to manage and share them across a team or company.
📌 TL;DR
Slack Code → AI coding work moves into a shared Slack channel, so the whole team can review it before it goes live.
Notion Skills Library → One shared home for your team’s AI instructions, but it still works best with Notion’s own agents.
Claude from your phone → You can finally start Claude Code from mobile, closing one of the clearest gaps with Codex.
Codex can text you → Codex can now send Apple Messages from your Mac.
Builder’s notes → I tried Paper for agent-led design, then turned my bloated-workspace cleanup skill into Tinder.
Slack Code makes coding agents multiplayer
When someone asks an AI coding agent like Claude Code to update a website or app, the work usually happens behind the scenes on that person’s computer. Everyone else only sees the result once it’s finished.
Slack Code brings that work into a shared Slack channel.
Tag a supported AI coding tool like Claude, Devin, GitHub Copilot, or Vercel, and Slack creates a channel for the job.
The channel shows what the AI plans to do, how it’s progressing, the changes it has made, and a preview of the finished result.
That means a marketer can flag the wrong wording, a designer can spot something that looks off, and a developer can check the code before anything goes live.
Slack doesn’t do the building itself. It gives your team a shared window into the AI coding tool you already use.
Once the job is finished, Slack archives the channel but keeps it searchable, so the team has a record of what changed and why.
Basically, it’s a group chat for building with AI. The agent does the work, developers keep control, and the rest of the team can finally follow along.
Pretty neat I guess.
Notion built a Skills Atlas inside Notion
A skill is a reusable set of instructions that teaches an AI how you want a specific task done.
You should be building lots of them...
Proposal generator skill
Brand guidelines skill
Research skill
The list goes on.
Once your company has 185 AI skills, managing them becomes its own problem.
Notion’s new Skills Library gives the whole team one place to create, organize, and share those skills.
Inside Notion, each skill is a normal page. Your team can browse them, improve them, and share them like any other Notion document.
Notion AI agents can then find and use them.
This is basically my Skills Atlas, but built inside Notion.
It makes the team’s best AI processes visible and reusable, instead of leaving them trapped on one person’s computer.
Notion also says the library works with AI agents running on your computer, like Claude Code, Codex, and Cursor.
Technically, it does. But their current solution is to download the skill from Notion and install it on your computer.
That downloaded copy has no connection back to the shared library.
If someone improves the original skill in Notion, your copy won’t update. It’s basically the equivalent of keeping all your skills in a shared Google Drive folder.
To get the full value from this today, your company needs to use Notion Agents. They can work directly from the shared library and use the latest version of each skill.
In the replies to the launch post, the Notion team said support for syncing skills across other agents is coming.
That would make this much more interesting.
For now, it’s very useful for teams already using Notion’s agents. For everyone else, the shared library is there, but keeping your agents updated is still manual.
thats why I built skills atlas :)
Claude just fixed its biggest mobile gap
damn straight.
Claude’s Remote Control already let you continue a Claude Code session from your phone, but you had to start that session on your computer first.
That meant you could leave your desk, check its progress over lunch, answer a question, or steer it from the Claude mobile app.
But if you were already away from your computer and wanted to start something new, you were stuck.
This update fixes that.
You can now choose a connected computer inside the Claude mobile app and start a brand-new Claude Code session directly from your phone.
Remote Control is basically a walkie-talkie for Claude Code.
Claude Code still runs on your computer, where it can use your files, tools, and project setup. Your phone gives you a live window into what it’s doing.
The phone and computer stay connected to the same conversation, so you can start something while you’re out and continue from your laptop when you get back.
It also handles short internet dropouts, Wi-Fi changes, and your laptop going to sleep. Claude Code reconnects once the computer comes back online.
Your computer still needs to be running for the work to happen, but you no longer need to be sitting in front of it to get started.
Codex can now text you
Codex can now read Apple Messages on your Mac and send texts on your behalf.
You can’t text ChatGPT to start a chat or continue a session, but it could text you a morning brief, inbox update, or weekly report.
It sounds like a crazy new release, but Claude has had the same feature for 4 months.
You approve the message and recipients before anything sends. More here.
Also this week...
Cursor is building its own GitHub → Origin gives your team one place to store its code, review changes, and let Cursor’s AI agents work on it. You can start a project there or connect one from GitHub.
Claude Design is now built into Claude Code → Type /design to create a few design options, edit or choose your favourite, then have the same agent build it.
💡 Builder's notes
You NEED to try Paper
I saw a few people talking about Paper, decided to try it, and my god am I impressed.
The simplest description is Figma, or a shared design canvas, built for AI agents. (I don't know how to use Figma btw)
You connect Paper’s MCP (the connection that lets Claude control the design board), then tell your agent what to create.
I asked it to explore three visual directions for my new education product.
I used Wispr Flow to talk through my favourite parts, Paper produced three more options, and I repeated that loop until I found a style I actually liked.
from what I’ve heard it’s lighter and more agent-native than the Figma with the MCP
And honestly, it absolutely shits on Claude Design.
design exploration
exploring buttons
font exploration
color pallets
hero mockups
I started with websites, landing pages, emails and social graphics.
Then I pushed it further and used it to design YouTube thumbnails for a new vlog and my Skills Atlas video.
I turned workspace cleanup into Tinder.
When you work with agents, folders and projects get bloated with a bunch of bullshit very quickly.
I found mine filling up with useless Markdown and text files from marketing and strategy work, plus new folders Claude had created for no real reason.
After a month or two, the whole setup gets completely blown out.
Your memory and CLAUDE.md files (the instructions Claude reads before it starts working) can also fill up with repeated or contradictory rules.
I built a skill called /spring-clean to audit all of it.
It checks your folders, files, memory and instructions, then turns every problem into a decision you can review. It diagnoses everything first without moving or deleting anything.
My original version of this skill gave me a massive long list inside the chat and I couldn’t be bothered to read it all, so I turned the review into a Tinder-style interface.
Each problem gets its own card explaining what it found, why it matters, what it recommends and how risky the change is.
Swipe left to delete, right to keep, up to archive, and down to move or fix.
It has turned incredibly dull workspace maintenance into a queue of quick decisions I can actually finish.
skill available for community members :)
