I've been experimenting with an orchestration-first approach instead of relying on a single model to handle an entire workflow.

The project started as a way to explore a real customer scenario, and along the way it evolved into a long-form publishing workflow involving multiple specialized agents, MCP/A2A services, evaluation loops, and supporting infrastructure.

By the end, the system had processed 26 billion tokens and grown to include 25 agents and tools, 30 agent skills, 27 packaged skills, 22 projects, 12 MCP/A2A-native services, 8 full-stack services (API + UI + MCP + A2A), 318 PRs, and 423 commits.

My goal as CTO was to go deep into a real customer scenario myself before asking my engineering organization to build in this new way.

The project is here: https://theisaiahchronicles.com

Would love to hear how others are approaching orchestration and multi-agent systems.

macOS requires users to 'select' a window first before being able to interact with UI elements within. This leads to more clicks, and I personally found this tedious. Furthermore, this behavior was inconsistent, with some applications actually supporting 'Click Through'.

I was not able to find any solutions online without drastically changing the behavior of the OS. In the end I found Hammerspoon and via AI, quickly put together a neat script that seems to work flawlessly (I have also already tested it works on the beta of Golden Gate).

This script enables click through on macOS, allowing you to click UI elements inside inactive windows without clicking the window first, solving the aforementioned problem.

Feel free to try it out and submit improvements. I submitted this on HN since I figured some users are looking for something similar since a few years.

I built the weather radar experience I actually wanted to use.

It's called LiteRadar — https://literadar.com

It’s: - 100% free, with no ads - Ultra-fast - Beautiful visuals with smooth 60fps animation

Weather radar apps make you look at ads, use a specific device, and hit paywalls to get at data that is freely provided by NOAA. On the other hand, the NOAA pages are ugly and unpleasant to me. So, I went on a side quest to build a weather radar experience I actually wanted to use.

I wouldn’t run this service if it weren’t insanely cheap to run. After some careful optimization (with the help of Fable 5), I was able to fit it comfortably in the free tiers of Modal, Cloudflare, and Vercel. I can offer it to everyone for free, no-ads. I guess this could change if it really blew up, but I doubt that will happen.

Here’s the core trick. I was frustrated with the jankiness of traditional radar imagery. I had to fix it. In this app, we interpolate radar imagery in real time on the GPU with optical flow samples around each radar time increment. The shader approximates Lagrangian advection—not a perfect weather simulation, but reasonable for 2 minute interpolation. This means you can scrub the slider and get a silky smooth animation. Yes!

How it works. NOAA publishes MRMS, a free composite radar dataset in two-minute increments—the same underlying public data many radar apps use. LiteRadar processes each new frame with a hyper-optimized Modal job that generates map tiles and computes per-frame optical flow. After optimization, the pipeline became mostly I/O-bound, taking about 4-5s every 2 minutes to handle the entire US.

The tiles are packaged as PMTiles for fast range requests and stored in Cloudflare R2, where egress is free. The frontend is a single-page Next.js app on Vercel.
