Most background dev automations are a pain to configure. You either hide scripts in your OS crontab or set up an over-engineered cloud runner. Antigravity sidecars offer a clean alternative: simple background processes managed right inside your workspace. 🧵

Do you find yourself being unnecessarily polite to your coding agents? I literally can't stop myself from saying "please" and "thank you." My only hope is that this somehow goes into training data and balances out some of the bile in old StackOverflow posts. 🤣

I redid my personal site over the weekend, updated some links, and added the few of my poems that I got published. I remember building my first web page in '94, and feeling like it was a creative act. This still felt that way, which is a relief in the age of AI-assisted coding.

Are you creating agentic that involve money or the need for local services when preparing fields for display (date formatting for example?). If so, A2UI's client-side functions can help you give your agent the ability to run local code quickly and declaratively!

Are you using a single agent for every coding task? A setup using multiple agents (each with its own context, role, skills, and rules) can help you leverage different models for different tasks, compartmentalize context and errors, and get things done faster.

Does anyone have resources to recommend on managing large libraries of skills? Example: If I have a single reference file that's useful for two different skills, what should I do? Live with the denormalization and put it in both? Combine the skills somehow? Share it in a bucket?

Python or Go? (This isn't intended as cheap flamebait -- I've been working more on the backend of agentic apps, and I'd like to focus on one of the two languages until I feel like I really understand what's up. I genuinely welcome and will likely act on your opinions 🙂)

Having recently moved out of the Bay area, it's a new and mildly unsettling experience to sit in my basement home office during a thunderstorm, listening to the sump pump churn and knowing that its tiny impeller is all that stands between me and a submerged desk. 🤣

Publishing an llms.txt is now nearly free, and adoption is climbing. Getting an agent to actually read it is the hard part. We benchmarked both sides. There's good news and bad news.

[Using Antigravity to port the Python AGY SDK to Dart] AGY: Hmm. Python SDK relies on a prebuilt binary. Me: Native hooks, then, or direct downloads? AGY: Looks like someone already published a Dart Antigravity package nine days ago. Maybe we just copy theirs? Me: 🤦🏻‍♂️

What I Learned This Week Part Six, in which our hero learns that the thing he discovered last week was discovered by someone else last month and already has a buzzword.

It's Monday, which means another "What I Learned This Week" video. In this one I've got updates on v1.0 of the A2UI protocol for GenUI, my first foray into Dart Functions on Firebase, and more!

Me: Hey, Antigravity, can you test my game like a real player? AGY: Sure! I'll just add flutter_driver, make a new entry point, add value keys to some of the widgets, figure out DTD via the Dart MCP, launch the app, teach myself Reversi, and start hitting buttons. Just wild.

I've been watching more highlight videos from Next '26. Fun to see what you get when people record videos in a hotel room on very little sleep. 😂 Here's a good one on full-stack Dart with Firebase, though! https://www.youtube.com/watch?v=XOU5dZJvHXk #GoogleCloudNext
