THIS WEEK'S BLOG POST

​Agent Skills explained: Replacing AGENTS.md with reusable AI knowledge​

AI development changes so fast, it's hard to keep up! I'm doing my best to dive in, but one step at a time. Before jumping into a new MCP, tool, or anything, I want to have the idea that I own the current workflow. One thing I've recently added are Agent Skills and they've had a major impact on the code quality of my agent tasks.

I also decided to introduce a dedicated AI Development SwiftLee category, so expect more articles to come! And finally, the above article is also available as a YouTube video:

WHAT I'M WORKING ON

Fighting App Reviews

I couldn't really describe it differently. Last week, I tried to get my YouTube app approved for TestFlight. It got rejected because my Google OAuth app was not approved. That one got rejected because my app name was not valid according to Google's terms.

So I found a new app name, purchased another domain, reconfigured everything, and submitted again. Rejected.

My app was sending data to AI services, which is not allowed according to Google's terms.

Long story short: my Google OAuth app is now approved and I'm working towards the first TestFlight build for my new app called Vydio. For those following my YouTube series on this app: I'm recording a fresh update video on all of this later this week!
