A reference for Lua 5.1 programming in World of Warcraft addons, including functions added or changed by the game. World of Warcraft is an online game, and addons are small programs that customize its interface.

Use it to check Lua functions, string and table helpers, math behavior, and WoW-specific APIs while writing or debugging retail WoW addons.

It helps avoid applying general Lua documentation that does not match the game’s restricted environment or Blizzard’s function behavior.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00041	$0.00400
Opus 5.5	$0.00016	$0.00160
Sonnet 5.5	$0.00008	$0.00080
Haiku 4.5	$0.00004	$0.00040

Security

Grade A, and why

wow-lua-api 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 1mo 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.

What it actually says

WoW Lua API (Lua 5.1)

Scope

Retail only.
Covers the Lua functions list and WoW-specific notes from warcraft.wiki.gg.
Does not cover OS or file IO libraries (they are not available in the WoW client).

When to use this skill

You need behavior or signatures for base Lua 5.1 functions used in addons.
You want Blizzard-specific differences (for example degrees vs radians).
You need WoW-only helpers like strsplit, table.wipe, or fastrandom.

How to use this skill

Start with references/OVERVIEW.md for environment notes and scope.
Use the library reference that matches the function you need.
Read the detail files for method-call syntax and table method caveats.

Reference files

references/OVERVIEW.md - Page-level notes, availability, and links.
references/BASIC_FUNCTIONS.md - Lua base functions and behavior notes.
references/MATH_LIBRARY.md - Math library plus Blizzard degree wrappers.
references/STRING_LIBRARY.md - Standard and WoW-specific string helpers.
references/STRING_DETAILS.md - String method-call syntax and pitfalls.
references/TABLE_LIBRARY.md - Table helpers and WoW additions.
references/TABLE_DETAILS.md - Table method-call behavior and wipe caveat.
references/BIT_LIBRARY.md - bitlib functions and performance notes.
references/COROUTINE_LIBRARY.md - Coroutine functions and cautions.
references/DEPRECATED_FUNCTIONS.md - Deprecated or obsolete functions.

What ships with it

10 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.

Changes

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.
