Four principles for the ritmo-pixel-art skill, each sourced in PIXEL-ART.md. They come from two blind tests run on 2026-11-11, each with one agent, a written brief, and no references:

  1. An isometric room, drawn from rules taken from a pixel artist's making-of video.
  2. Five pieces of Landkeep (house, granary, stilts, quarry, ruin), from their role and size only. The maintainer preferred them to the game's own pieces, which had been through review rounds.

New principles

  • Name each kind by one feature (Readability): start from what the piece does in the game, and exaggerate that feature until it reads at display size.
  • A solid shows three tones (One style): the top and two sides each get a step, chosen per piece. A line between parts is a choice, and at small sizes it is often noise.
  • Details on a slanted face are drawn flat, then laid on it (One style), along the view's slope.
  • Judge a set together (Judging): side by side, and in pure black.

Sources: Medeiros (low resolution), Slynyrd's Pixelblog 41 (the 2:1 line), the making-of video, Landkeep's own art direction, and the two tests.

This PR changes only the skill and PIXEL-ART.md. The bake changes that go with it are in a separate PR.

Verify: pnpm run check. Typecheck, lint, type tests and examples pass. Some test files timed out under a machine load of 100+, all in code this PR doesn't touch (core relations, music, netcode, devtools CLIs). Those same files pass when rerun at normal load.

…dged as a set

Four principles that held up in two blind tests on 2026-11-11 (an
isometric room from a making-of's rules, and five pieces of Landkeep from
their role and size), each sourced in PIXEL-ART.md:

- name each kind by one exaggerated feature, from what it does in the game
- a solid shows three tones chosen per piece; a line between parts is a choice
- details on a slanted face are drawn flat, then laid on it along the slope
- judge a set side by side and in pure black

The feature rule's examples named the chest and granary of the game the
rule was tested on, which a later test agent then read.
