What this skill tells your AI
The instructions your AI receives, as published by liberatedpixelcup/universal-lpc-spritesheet-character-generator in .agents/skills/visual-test/SKILL.md and read by Ahel’s review.
Run npm run test:visual after a change that affects first paint, panel
layout, or a class in
vite/purgecss-critical-safelist.ts.
Add cases under tests/visual/. Reuse waits in
home-helpers.ts. Wait for catalog
readiness via __LPC_waitCatalogAllReady (installed in
sources/install-item-metadata.ts). Do not import visual specs
from tests/tests.js. They are not Codecov-instrumented.
