WP Block Themes

When to use

Use this skill for block theme work such as:

• editing theme.json (presets, settings, styles, per-block styles)
• adding or changing templates (templates/*.html) and template parts (parts/*.html)
• adding patterns (patterns/*.php) and controlling what appears in the inserter
• adding style variations (styles/*.json)
• debugging “styles not applying” / “editor doesn’t reflect theme.json”

Inputs required

• Repo root and which theme is targeted (theme directory if multiple exist).
• Target WordPress version range (theme.json version and features vary by core version).
• Where the issue manifests: Site Editor, post editor, frontend, or all.
