[Cursor @cursor_ai]

We've doubled usage limits for all individual and teams plans!

These limits apply to Grok, Composer, and any new Cursor models.

[Dave Kline @dklineii]

Every CEO I coach asks me some version of the same question.

"How do I find A-players who make sh!t happen?"

At Bridgewater, I ran hundreds of interviews looking for this exact thing. We called it "acting like an owner." Others call it high agency. Here are 5 tests to find it:

driver.js now supports feature hints

Doubling compute doesn't always mean doubling capability.

Talking about scalability, sharding, and handling unexpected requests in the latest yt.

1/ We're open sourcing AppLess.

Last week we asked: what if your phone didn't need apps at all? It resonated wildly - tons of DMs, a lot of conversation, some skepticism but also genuine curiosity.
Coincidentally, Monogram launched the same day, promising a more visual AI. Two sides of the same coin - both challenging the premise that AI has to be a chatbot.

Now the AppLess side of the coin is yours to fork 🧵

[Boris Cherny @bcherny]

I talk to engineers at other companies every day and hear the same thing: one person is 10x'ing their output with Claude but the rest of the org hasn't caught up.

Watching teams adopt AI, I keep seeing the same 4 steps.

I mapped them out here: Steps of AI Adoption https://t.co/kQnRAUMKpP

My talk from AI Engineer is now live!

It covers how we're automating parts of AI research and building systems to rapidly improve our models. I cover some of the work our team did to train Grok 4.5 together with SpaceXAI.

[WILL NESS @WillNessAI]

I built a variant of @mattpocockuk's grilling skill dedicated to frontend and it has improved how I build new apps and components.

The general idea:
1. Use /grilling and /prototype as a base
2. Tell Claude to build 5 WILDLY different prototypes
3. Tell Claude to include a picker that lets you switch between each variant live
4. Each round you select your favorite(s) + leave feedback, and Claude will walk down each branch of the design tree, helping you zoom in on your desired design

And THEN, I went and added it to /wayfinder, so whenever I make a new map and there's novel frontend work, a ticket is created specifically referencing that /grilling-frontend-prototyping needs to be invoked.

This will not be the last time I build a cool skill and add it to Wayfinder; this is a very powerful pattern for planning work.

i wrote a post on how cursor does hiring 6 months back, but a lot has changed bc of the latest models

now onsite is just 5h to ship a full product from scratch

here's what the people who pass do differently:

[OpenAI Developers @OpenAIDevs]

Meet kbd-1.0-codex-micro, built with @work_louder.

Map the buttons and joystick to your workflow, and keep your pinned chats in view.

Get yours before stock returns 410.

[Expo @expo]

Expo UI is production-ready 🎨. Real SwiftUI on iOS, real Jetpack Compose on Android, from one set of components.

No more .ios and .android forks for the parts that should just be swift or kotlin.

[Aiden Bai @aidenybai]

can confirm - 5.6 sol is great at fixing React useEffect slop too!

prompt: "Run npx react-doctor@latest, triage each issue and create a central draft PR, then stack verified fixes onto that PR"

[Matt Pocock @mattpocockuk]

Here's a skill you can run once to set up deep modules in any TypeScript codebase:

- Each 'package' lives at src/packages/<name> (name/path is totally customizable)
- From outside the package, you can only import from <name>/index.ts
- Tests for the package live at <name>/tests, and can only import from index.ts
- No circular dependencies between packages
- Puts a context pointer inside AGENTS.md so the agent knows about it (no skills needed)
- Works with frontend or backend code (even Effect code!)
- Enforced by dependency-cruiser

This means you can hide stuff inside modules, with only a single test seam exposed. Clear seams, deterministically enforced: no more shit tests.

Awaiting a merge. Should I ship it?

How to make your own font with GPT 5.6:

> Go to Cursor/Codex
> Boot up GPT 5.6 Sol xhigh
> Say "Make me a custom font for my brand. *insert vibes*. *insert font references via screenshots*. Ensure you have ttf and otf files generated"
> Get result
> Provide feedback on all the little details: font weight, glyph height/width, etc
> Or be more drastic and say "change everything" to see different vibes entirely
> Loop the feedback until your happy
> Ask GPT 5.6 to make you a showcase website to display your new font

Voila enjoy your custom font that nobody else has

New skill: /improve-animations

Inspired by @shadcn’s improve skill I made one specifically for animations.

Use your most capable model to audit animations in your project and hand the execution to cheaper models.

Fable is available through July 12, so make good use out of it!

[shadcn @shadcn]

Introducing shadcn/typeset.

You know how you render markdown and get back plain, unstyled HTML? Headings, paragraphs, lists, tables. So you style the elements one by one: font sizes, line heights, spacing.

You do it for your blog. Then you do it again for docs. Then again for the chat. Every time, you're fighting the same thing: sizing and spacing.

To fix this, we created typeset.css: one file that styles everything inside a typeset container. It lives in your project, so you can change it directly when you need to.

And we made it work beautifully with streaming markdown.

[dotta 📎 @dotta]

Fable is *so good* at wireframes that we've shipped a /wireframe skill built into Paperclip

It even makes a beautiful website you can share with the team (link below)

I use it for pretty much all of my new features now

[Emil Kowalski @emilkowalski]

New skill: /apple-design

Apple’s WWDC videos are a goldmine of knowledge. I’ve combed through my favorite ones and came up with 17 design and motion principles.

Use them to review existing work or when working on something new to get it right.

CTO shared this with me on day 1

something everyone should read if they are in an early-stage startup at least once
