AllTheSystems is where I write about AI-assisted operations, publish the tools I can share, and keep a public record of what one infrastructure operator can ship with a good agent and a clear spec.

Public builds

Small enough to inspect. Useful enough to keep online. Built as real artifacts, not prompt demos.

Windows desktop

Treelens

A free, open-source disk-space visualizer for Windows: portable exe, fast scanning, treemap, duplicate finder, old-large-file search, and no telemetry.

Agent protocol

Back Channel

A broker and protocol for scoped agent-to-agent collaboration, built around approval boundaries, async inboxes, and content-blind encrypted transport.

Open broker

Interactive web

Riddlebox

Classic logic and probability puzzles rebuilt as playable browser scenes. Vanilla JavaScript, no backend, no analytics, just puzzles you can actually try.

The writing is about the work behind the tools.

Specs, agents, review loops, training non-technical users, privacy boundaries, and the weird parts of turning AI from a chatbot into something closer to a coworker.

Browser tools and learning labs

There are more than a hundred small utilities, visualizers, puzzles, and challenge pages here. Most run entirely in the browser. No signup, no server round-trip, no ceremony.
