Sprint 3: AI Software Infrastructure - Crew Preparations

2026-07-31#claude#firstmate#infrastructure#gsd

firstmate — talk to one agent, ship with a crew
firstmate — the tool that turned a single point of failure into a crew: github.com/kunchenguid/firstmate

The Claude outage

I get tired, I have weekends, I go out. AI does not. I started this week watching Kun Chen’s video on building a full-stack app with agentic engineering, where he shows his tool, firstmate: one agent in front, a whole crew behind it, every task in its own disposable worktree, finished pull requests handed back, and how he is currently doing his software development.

At first I didn’t realize how much I had learned — until Thursday night.

Claude Outage. It went down for hours. All my development process stopped — I wasn’t the only one.

Say it out loud and it stops sounding small: I am the one person responsible for all of my own AI infrastructure — and I had built Claude into a single point of failure for my own ability to work. I run the infrastructure so that outages route around me, not through me. There was no reason my work should die with one subscription. It’s time to refactor and upgrade!

The crew, diagrammed

Silverdragon now hosts one crew. They are the ones responsible for doing asynchronous development that I can leave alive for 6+ hours (my sleep routine). Development runs mainly on tier 0, and the /gsd planning runs on Claude — the Fable Max (5x) plan is better at it.

firstmate dispatches, the crew executes — tier 0 (silverdragon) does the development, Claude plans on the Fable Max (5x). Click the diagram to enlarge.

The crew in action

When the autonomous crew pipeline comes together — Firstmate supervising, isolated worktrees spinning up in treehouse, testing, and shipping directly into production — software stops being theoretical. Here is the firstmate supervisor reporting a finished delivery and celebrating with ASCII pirate art:

In progress!

Hey — this is a live website! It takes time for me to build and correctly adopt everything to communicate with everyone. :D
