What it does

Shopify Theme Check

Run shopify theme check and resolve issues, prioritizing:

  • Liquid errors — undefined objects, bad filters, unclosed tags.
  • Performance — render over include, avoid {% assign %} inside tight loops, lazy-load offscreen images.
  • Accessibility — image alt, form labels, heading order.

Treat the config in .theme-check.yml as the source of truth; don't disable a check to silence a finding without explaining why.
