The watch for WoW addons

Patch day shouldn’t be a fire drill.

AddonSentry keeps the exact API surface for the live World of Warcraft client build. Every pull request is validated against it — and when a new build lands, a patch-break scan checks your addons against the new API and tells you precisely which lines broke, before your players ever see a Lua error.

Patch-break detected
Scanned against build 11.1.5.61240 — 7 lines across your addons reference removed API.
Tracking issue opened with every breaking line, by file and number.

Every major patch quietly rewrites the API your addon stands on.

Functions vanish. C_* namespaces get reshuffled. A field you’ve called for years returns nil. You don’t find out from a changelog — you find out from a screenshot of a Lua error, posted in your Discord, minutes after the servers come up. AddonSentry exists so that never happens to you again.
What stands the watch

The same pipeline that keeps the Peavers suite green — hosted for you.

Two analysers, run against definitions regenerated for every client build. Not a generic linter guessing at the API: the real surface, build by build.

01 / VALIDATION

Build-accurate checks on every PR and push.

luacheck catches the existence problems — undefined globals, C_* and Enum field typos, syntax. lua-language-server goes deeper into signatures: argument and return types, nil-safety. Both post straight to a GitHub Check Run, and we annotate only the lines your change actually touched.

The differentiator

Patch-break detection.

We already hold the new API surface before you do. When a build lands, run a patch-break scan and we check every active addon against it, opening a tracking issue listing exactly which lines break — so you ship the fix on launch day, not after the bug reports.

03 / AUTO-FIX

Fixes written by Claude.

Turn any finding into a minimal, reviewable pull request. Gated by your auto-fix mode and credits — nothing merges without you.

+ name = C_UnitAuras.GetAuraDataByIndex(unit, i).name
04 / ZERO-CONFIG

Install once. Stand down.

Add the GitHub App to your addon repos and you’re done — no CI to write, no toolchain to pin, no definitions to maintain. The build-accurate definition set lives on our infra. You write Lua; we keep watch over the API beneath it.

How it works

Three steps to a quiet patch day.

1

Install the GitHub App

Pick the addon repos you want watched. Public or private — it takes about a minute.

github.com/apps/addonsentry
2

Open a pull request

A Check Run posts back against the live build, annotating the lines your change touched.

luacheck + lua-language-server
3

Run a patch-break scan

When a new build lands, scan your addons against it — we open a tracking issue with the exact lines that broke, and an optional fix to review.
