# WoW AddOn Structure (Retail)

## Scope
- Retail only, current as of Patch 12.0.0.
- Focuses on folder layout, .toc metadata, loading order, and SavedVariables.
- Avoid deprecated or removed APIs and call out restricted directives.

## When to use this skill
Use this skill when you need to:
- Design or review an AddOn folder layout.
- Author or audit a .toc file.
- Reason about file load order and login events.
- Wire SavedVariables or troubleshoot persistence.
- Query or load AddOns via `C_AddOns` APIs.

## How to use this skill
1. Start with layout and naming rules in references/ADDON_STRUCTURE.md.
2. Build the .toc file using references/TOC_FORMAT.md.
3. Plan initialization order with references/LOADING_LIFECYCLE.md.
4. Wire persistence with references/SAVED_VARIABLES.md.
5. Use `C_AddOns` metadata APIs from references/C_ADDONS_API.md.
6. Cross-check patterns in Blizzard UI source from references/VIEWING_BLIZZARD_UI.md.

## Reference files
- references/ADDON_STRUCTURE.md - Folder layout rules, naming, and common patterns.
- references/TOC_FORMAT.md - .toc syntax, directives, and file order rules.
- references/LOADING_LIFECYCLE.md - Load order, events, and login timeline.
- references/SAVED_VARIABLES.md - Persistence rules and file locations.
- references/C_ADDONS_API.md - Key `C_AddOns` metadata and load APIs.
- references/VIEWING_BLIZZARD_UI.md - How to inspect Blizzard UI source.

## Key rules and reminders
- The AddOn folder name and .toc filename must match.
- The .toc file is required and defines file load order.
- Files load top to bottom in the .toc list.
- SavedVariables are available after `ADDON_LOADED` unless `LoadSavedVariablesFirst` is used.
- Use `LoadOnDemand` and `C_AddOns.LoadAddOn` for heavy modules.
- Some .toc directives are restricted to Blizzard AddOns and are not available to third-party AddOns.
