Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00181 | $0.02521 |
| Opus 5 | $0.00090 | $0.01260 |
| Sonnet 5 | $0.00036 | $0.00504 |
| Haiku 4.5 | $0.00018 | $0.00252 |
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
.xmlfiles.
When to Use This Skill
Use this skill when you need to:
- Write or read WoW addon
.xmlUI 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.,
Buttoninherits fromFrameinherits fromLayoutFrame)
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 ships with it
5 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

wow-api-xml-schema is a skill published in the GitHub repository JBurlison/WoWAddonAPIAgents (43 stars, last pushed 6mo ago), licensed MIT. It adds 181 tokens to every session and 2,521 once invoked, about $0.0009 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
