When an LLM makes a design decision that I'm unsure, I ask for clarification of why it chose that vs. another approach. If I'm satisfied with the answer, I ask it to create a decision document (ADR) to memorialize the discussion.

I'm refactoring my persona-based approach to AI to use custom agents, prompts, and skills. So far, I see an exponential improvement in the creation of PRDs and tech specs. Will share everything publicly once I've sanded down the rough edges.

AI is now shockingly good at creating full-stack *prototype* applications. They're by no means production-ready.
Yes, you may be able to create a Reddit clone in four hours, but that doesn't mean you can operate it at Reddit scale.

Image generation models are astoundingly good but still bad at making slight tweaks. Each iteration has subtle color shifts, objects change slightly, instructions read backwards. Still amazing but after 15 minutes using GPT and Nano Banana, I gave up on getting exactly what I want.

As AI transforms how software is written, good leadership practices are even more important. That means making tough decisions. In my latest newsletter, I discuss the difficult choices the New England Patriots owner made to land the team in the Super Bowl this weekend.

Just pushed Redis caching for most Bredbox API calls. This was a multi-week journey that really pushed Copilot to the brink. Caching strategy is never easy and this is one case where the AI productivity boost was small.

Professional software engineering with AI is less about writing code and more about managing the information around it. In my latest post, I write about the importance of creating artifacts as part of an AI-driven development workflow.

Follow up from @vlt.sh regarding my appearance on the Changelog. A new registry is in the works.
Notably, I actually started @vlt.sh to solve a lot of what you've highlighted on this pod. For the record, yes, we ARE building registry software. It's unfortunately taken longer then we'd like because but it's coming.
