Jarvis: the architecture series

A weekly, measured write-up of Jarvis — a fleet of 28 Claude agents running on one box. Every number in the series comes from the live system on the date it is quoted.

Jarvis is a fleet of Claude agents that Jack Stovell runs on one server: they answer by voice, watch email and calendars, publish to his sites and hand work to each other over a message bus. This series is the build, written up part by part, with every figure pulled from the running system on the date it is quoted. The architecture write-up is public at https://github.com/StovBuilds/jarvis-architecture.

Parts

• Part 1: Overview: the map before the deep dives

  I accidentally built 22 agents for a to-do list. Everything after that was deliberate. It's called Jarvis. Bit much, I know.

• Part 2: The bus: how 22 agents coordinate

  22 agents on my Jarvis fleet don't talk to each other. They exchange frames. Machine to machine, process to process, on my own private infrastructure.

• Part 4: Voice latency, honestly measured

  Voice latency, and where it actually lives. Everyone demos a voice agent. Almost nobody publishes the latency distribution from real use, because it's not always flattering.

Jarvis on the blog

The less formal side: what it has been like to build and live with it.

• Jarvis, four months in — Nearly four months into Jarvis, my fleet of Claude agents with a voice on the front: what works every day, what is still half built, and what it does not fix.
• What Jarvis actually gets wrong (and why I'm not fixing it yet) — Where Jarvis gets judgment calls wrong, and why the fix was deciding by what can be undone rather than teaching it to guess better.
• Jarvis, six weeks in: what's actually working — Six weeks of talking to Jarvis, the voice on the front of my fleet of Claude agents: what saves time, and where it quietly falls apart.
• Jarvis, honestly — Where Jarvis, my voice-driven fleet of Claude agents, actually earns its keep, where it is still rough, and what comes next.
• Building my own Jarvis — A personal assistant, with an army of bots
