Does it help with data preparation for Handlebars templates?

Yes, it details how to use getData() for V1 and the asynchronous _prepareContext() and _preparePartContext() methods for V2 to ensure templates receive the correct data.

Does this skill support both ApplicationV1 and V2?

Yes, it provides comprehensive documentation and implementation patterns for both the legacy ApplicationV1 and the modern ApplicationV2 sheet architectures introduced in V12.

Can I use this for both Actors and Items?

Absolutely. The patterns covered are applicable to ActorSheet, ItemSheet, and any custom DocumentSheet classes within the Foundry VTT ecosystem.

How does it handle event binding in V2?

It utilizes the modern static actions pattern within DEFAULT_OPTIONS, providing a cleaner and more efficient way to handle UI interactions compared to the legacy activateListeners method.
