What problem does it solve?

This skill provides compatibility wrappers to migrate Foundry V12/V13/V15+ code away from deprecated globals to modern namespaces, enabling safe cross-version development and maintenance.

Core Features & Use Cases

  • Compatibility wrappers for Foundry APIs moved to namespaces (ActorSheet, ItemSheet, TextEditor, and more).
  • Deferred sheet registration using the DocumentSheetConfig to support V13+ and V15+ workflows.
  • Cross-version template loading and HTML enrichment with a unified approach.
  • Clear guidance and patterns for caching lookups and safe fallbacks to ensure stable modules across Foundry versions.

Quick Start

  • Set up the compat wrappers described in scripts/compat.js and scripts/compat-helpers.js.
  • Obtain the appropriate base class with getActorSheetClass() and extend it for your actor sheets.
  • Register sheets in the ready hook using registerActorSheet and registerItemSheet.
  • Preload templates with loadHandlebarsTemplates and render them via the modern API.
