Writing about software, food, life.
Decision tree: ship code with AI agents vs. build an agent application — branching into Claude Code, Codex, Cursor, OpenAI Symphony, Stripe Minions, Shopify Roast, Google ADK, Microsoft Agent Framework, and AgentOS

The Harness Engineering Cheat Sheet

The Harness Engineering Cheat Sheet I have a Cursor problem. Or maybe an “agent session” problem more generally — I keep five or six chats open, each with its own slice of context, each in a slightly different state. We have nice skills. We have nice tools to fetch the right context. We have a code-review skill that drops inline comments on a PR. But I still lose track of which window is doing what, and occasionally paste the wrong thing into the wrong session. ...

I Built an AI Ultrarunner to QA My App

I Built an AI Ultrarunner to QA My App I’ve been building a race tracking app for ultrarunners. It lets you manage your race calendar, track gear, write journey entries, and plan your season. The problem? I have no users yet. Just me. That means nobody is poking around, trying weird things, or stumbling into edge cases. The app has unit tests, CI checks, type checking — all the usual stuff. But there’s a whole class of bugs that only surface when someone actually uses the thing. Opens the browser, clicks around, creates records, and goes “wait, that doesn’t look right.” ...

But the whole time, I kept hearing about the 50-mile course — how it takes you through parts of the island that are normally off-limits to the public, covering nearly the entire island. That thought stayed with me. ...

Imogene Run

Breathing Through the Sky: My Imogene Pass Run This weekend I had the privilege of lining up at the 52nd annual Imogene Pass Run, one of the most beautiful, brutal, and humbling races I’ve ever attempted. The Start: Breathless From the First Steps From the very first few miles, the altitude grabbed hold of me. I was breathing hard right away, trying to find rhythm while surrounded by so many strong runners. The biggest contingent came from Flagstaff, a town that clearly knows how to send mountain-ready athletes. ...

Running Post Hysterectomy

You might be reading this because you are told that Hysterectomy is the best option for removing uterine fibroids which has been bothering you a lot … but your biggest concern is how soon you can get back to your beloved activity - running. It’s a bit of a dilemma, isn’t it? On one hand, you want to take care of your health and get the surgery done, but on the other hand, the thought of being sidelined from running can be a tough pill to swallow. In fact I postponed for a year or two myself but so glad I got it done. ...
