Feels like you could start being productive in Effect | TypeScript for the AI Era with only 10-15 functions, but I have no idea yet which of the 500 or so of them I should choose. Still, my investigations continue.

I was today years old when I learned you can do CMD-SHIFT-L to select all occurrences of a piece of text in VSCode. How many hours have I wasted repeatedly hitting CMD-D 😬

gql.tada is just nuts. Instant type inference from graphql strings. It's like tRPC for GraphQL.

I poured my 10 years of teaching experience into a skill. It's called /teach, and it can teach you anything. Here's how it taught me to solve a Rubik's cube:

/grill-me and /grill-with-docs are changing No more "one question at a time" - now it asks questions in rounds Faster, less token spend, but still keeps dependencies between questions clear. Shipping in v1.2

/wayfinder lets you plan your most ambitious projects ever You can give it a destination and it will: - Figure out the frontier of things that can be decided now - Uncover the route ahead as you go - Research, prototype, and discuss with you - Maintain a map in an issue tracker of your choice (GitHub, Linear, etc.) It's revolutionised how I plan coding work - and I'm even using it outside of coding.

My Ralph Wiggum breakdown went viral. It's a keep-it-simple-stupid approach to AI coding that lets you ship while you sleep. So here's a full explanation, example code, and demo.
