I don’t wanna “build software” so much as
build understanding and express it in software.

The concern about AI-generated code is that the quality is worse. However, @jessitron thinks that when we use AI to develop better features rather than build faster, the ceiling isn’t our imagination. It’s the development system we build around the agent.

Today I have learned: with Claude Managed Agents, do not attempt to define them in the UI.
There's a cli for that, and it offers options that don't exist in the UI. And of course, you can make claude code work it for you
To get aligned with agents, I make them build me a fancy HTML description of what they're thinking. Then I tweak it and comment on it until we both know what we're about.
Here's my iterate-on-docs skill, plus a tool that makes this work with HTML.

A friend of mine got moved to a redeye flight, so he needed to tell the hotel he'd arrive early in the morning. He got Claude to do it.
> it found the reservation in my email and pulled the hotel contact info from their website 😁
> oh actually it found the hotel manager’s personal email address on LinkedIn 😩

Because learning the hot framework of the moment isn't the knowledge that prepares you for everything else
k, I gotta say, since @bouhmad and @Cloudflare fixed my account, I'm super glad to be using Cloudflare Workers.
They're awesome! It does everything I want, all my routing, with tracing. Serves a static site too. amazing
Free for my purposes, but take my $5/month you deserve it

heya @jessitron, I'm the PM over on the IAM team @ CF. Nice to meet you!!
Heads up, your user was showing as not having it's email verified, but we saw your tweet and we went ahead & automatically verified your user this AM, so you should be set here. We're also separately working on adding a banner to make email verification resends easier, should go out later today
Thanks again for all the patience here 🙇🏽
LMK if you run into any other issues, always happy to help. Also can DM ^^
I wanted to use Cloudflare workers today, I was excited to try it.
It fails with "verify your email address [10034]" and I verified that years ago, there's no way to redo it (change email is also broken)
Their help bot also fails with "verify your email address"
I guess it's back to AWS lambda for me
Can we use AI to be smarter about in-app notifications?
When do I want to know about the changes you've made?
(hint: almost never)
Certainly not when it's my first time in the app.
opening any app is a gauntlet of popups. Can we be smarter?
I report (again) that software is magic: express your intentions well enough, and the world works that way.
and AI-that-writes-software is better magic: express my intentions clearly enough in English, and the world works that way.
At least a little piece of the world.

Who are we in the age of AI?
as developers,
as people,
as humanity?
