TileMon

TileMon shows your work as a treemap on a fixed canvas: every task is a tile, and a tile's area is how much of your attention it deserves. You set the sizes by dragging, which takes space from everything else — you cannot mark ten things urgent at once. Your coding agents don't touch the sizes; they push status over HTTP, so a task they're stuck on glows amber when it needs an answer and red when something's broken, readable from across the room on an always-on monitor. It comes in two halves: npx tilemon runs a local server over a folder of JSON boards, and tilemon.com is the hosted version for when your own machine is asleep.

I built it because the question I actually have all day is narrow — what are my agents waiting on me for — and a task list answers everything except that. Anything that would add noise rather than direct attention is deliberately left out.

The architecture rule is that the board owns no data: it's a renderer over a source. The npm package's renderer is reused verbatim by the hosted app, which wires the same callbacks to Postgres instead of a JSON file. The local tool is zero-dependency Node rather than my usual stack, which is the point — npx and nothing to install.
