wow-api-xml-schema

wow-api-xml-schema is a skill for Claude Code, Codex from JBurlison/WoWAddonAPIAgents. It costs 181 tokens per session (2,521 once invoked), scanned A, original, MIT.

A complete reference for the XML format used by World of Warcraft add-ons to define interface elements such as frames, images, text, fonts, and animations. XML is a structured file format that describes layouts and relationships rather than drawing them in code.

In plain words
What is it for?
Use it to write or inspect .xml files for WoW add-on interfaces. It covers frame types, virtual templates, inherited layouts, layers, scripts, key-values, sizing limits, includes, and animations.
Why use it?
It explains the allowed XML elements, attributes, defaults, templates, inheritance, anchors, scripts, and file-loading rules. This helps prevent invalid add-on UI definitions and makes XML layouts easier to connect with Lua code.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

wow-api-xml-schema scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

WoW XML Schema

This skill documents the XML schema for World of Warcraft addon development. XML files define User Interface elements declaratively — frames, textures, font strings, fonts, and animations. While most UI functionality is also available in Lua via the Widget API, XML provides a structured way to define layouts, templates, and widget hierarchies.

Source of truth: https://warcraft.wiki.gg/wiki/XML_schema XSD file: https://raw.githubusercontent.com/Gethe/wow-ui-source/live/Interface/AddOns/Blizzard_SharedXML/UI.xsd Current as of: Patch 12.0.0 (Retail only) Scope: All XML elements and attributes used in WoW addon .xml files.

When to Use This Skill

Use this skill when you need to:

  • Write or read WoW addon .xml UI definition files
  • Define frames, textures, font strings, or animations in XML
  • Set up XML virtual templates (virtual="true") and inheritance (inherits="")
  • Understand which XML attributes map to which Lua API calls
  • Configure anchors, layers, scripts, key-values, or resize bounds in XML
  • Set up the <Ui> root element with proper namespace declarations
  • Use <Include> and <Script> tags to load files from XML
  • Define <Font> or <FontFamily> objects for text styling
  • Create animation groups and animations declaratively
  • Build intrinsic frames (intrinsic="true")
  • Understand XML element inheritance hierarchy (e.g., Button inherits from Frame inherits from LayoutFrame)

Relationship to Other Skills

Skill Relationship
wow-api-widget Covers the Lua-side Widget API methods called on widgets. This skill covers the XML-side declarative definitions. Many XML attributes map directly to Widget API methods.
wow-addon-structure Covers .toc file format and addon loading. XML files are listed in .toc and loaded in order.
wow-api-framexml Covers FrameXML helper functions and mixins. XML mixin and secureMixin attributes reference Lua mixins documented there.
wow-lua-api Covers the Lua 5.1 environment. <Script> tags execute Lua code within that environment.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
