@bcherny is there a way to get commands and subagents working in cowork the way they do in Claude code? I opened a folder that had .claude commands and tried to invoke the command in cowork, crashed the app 😩😬

our phones are still pretty dumb. here’s an example:

The OS should be applying AI to understand the purpose of each app (maybe apps can also have a manifest file specifically for operating system AI) and give you OS level notifications based on its understanding of the context of what your apps are doing. 💯

liquid glass is ... "interesting", but it’s not the evolution we need.

@karpathy In the next version of Cursor, stuffing context will get much easier :D

@leenyburger Worth checking out @relume_io. They let you export to figma, with the export including a brand book.

@laracasts G and H keep things consistent.

@svpino Cursor is next level. The composer + agentic mode coupled with an experienced engineer giving it iterative guidance is a productivity boon

The only methodology that makes sense for how this was implemented:
1. an app clip (a lightweight version of an app that does not need to be installed) is triggered through an iMessage link
2. the app clip's sole action is to launch a live activity and disappear
3. the live activity remains visible on the lock screen and dynamic island until dismissed by the user

According to Apple's docs: "Your App Clip can’t typically include app extensions, but starting with iOS 16 you can include a widget extension that offers Live Activities and displays live event data without requiring people to install your full app."

Frantically googling how @nikitabier got iOS live actions to display for @explodeapp message recipients that haven’t downloaded the app… 🤯 Anyone?

@svpino You can set up stubs instead of using mocks. Using dependency injection to make the tested classes have the stub as a dependency means you get to have unit tests that are highly targeted and FAST.
