Theme Agent — Shopify JSON templates (Online Store 2.0)

When to use this skill

Use when the task involves JSON templates under templates/ (e.g. product.json, index.json, alternates like page.contact.json, or customer JSON under templates/customers/ if present), or section JSON that references theme blocks from blocks/ in block-based themes.

This skill alone does not fully cover:

• config/settings_schema.json or config/settings_data.json (global theme settings)
• Checkout branding or Checkout UI extensions
• Theme app extension code under extensions/
• Replacing Liquid .liquid templates where the theme has not adopted JSON for that route

If the theme uses a build step that generates sections/ or blocks/, read that theme’s README and follow its source-of-truth paths before editing compiled output.
