WoW Addon Dev Wotlk V335a Claude Skill — Development skill for Claude Code

WoW Addon Development Wotlk v3.3.5a - Claude Skill

A [Claude Code Skill](https://docs.claude.com/en/docs/claude-code/skills) for developing, porting, and debugging World of Warcraft addons targeting the **3.3.5a client (build 12340, Interface 30300, Lua 5.1)** — the client base used by Project Epoch, Warmane, Ascension, Atlantiss, and other Classic+ private servers.

This is a generic skill for the WotLK 3.3.5a client; server-specific quirks (Project Epoch's custom seals/items, EpochFixes patterns, etc.) live in `references/server-specific/`.

What this skill gives Claude Code

• Routing for which reference doc to read for any given addon-dev task (porting, debugging, new addon, etc.)
• Lua 5.1 compatibility reference covering both directions of porting:
  • Vanilla 1.12 (Lua 5.0) → WotLK 3.3.5 (Lua 5.1) — what's now available, what still needs rewriting
  • Modern/Retail (Lua 5.2+) → 3.3.5 — every 5.2+ feature that breaks the parser
• Modern API → 3.3.5 replacement table covering C_Timer, C_AddOns, C_NamePlate, Settings.*, MenuUtil, atlas textures, and more
• API quick-reference for the high-frequency 3.3.5 surface (frames, events, units, auras, CLEU, items, tooltips, slash commands, SavedVariables)
• Frame/UI cookbook covering tooltip ownership, taint avoidance, hooksecurefunc patterns, SecureHandlers, OnUpdate throttling
• Ace3-on-3.3.5 specifics including the canonical xpcall fix and library version recommendations
• External tools guide for the MilkyWay Codex MCP server, the FrameXML mirror, the awesome_wotlk DLL, and BLP/MPQ tooling
• Three executable validators that can be run by Claude Code (or by you) on any addon source tree:
  • scripts/lint_lua51.py — catches Lua 5.2+ syntax (goto, //, &|<<>>, \z, _ENV, table.pack, bit32.*)
  • scripts/scan_xpcall.py — catches variadic xpcall (the Ace3 v36+ break)
  • scripts/validate_toc.py — catches bad Interface versions, forbidden TOC directives,
