  Route Three.js and browser game-development requests into the narrowest matching
  sub-skill of the 19-skill MengTo/Skills game-development family — level
  authoring, map editing, cameras, enemy systems and AI, monster rigs, action
  combat, encounter design, inventory, hybrid/Vesperfall assets, VFX, audio
  feedback, mobile controls, performance tuning, QA, changelogs, and release.
  Use when a task touches any of those for a playable web game, and fetch the
  matching sub-skill before doing the work instead of improvising. Route
  Unity/C# engine work to `unity-gamedev-skill-pack` instead. Triggers on:
  three.js game, browser game, webgl game, isometric arpg, enemy AI, game
  camera, game inventory, game VFX, game audio feedback, ship web game,
  playtest web game, mobile threejs game, game encounter design, monster rig,
  hybrid game assets.

  Best for Three.js, WebGL, and browser-native game repositories where the task
  is choosing and fetching the correct upstream MengTo/Skills sub-skill. Not for
  Unity/C# or Unreal engine work, generic web-app (non-game) performance,
  CI/CD pipeline design, or Steam marketing ops — route those elsewhere.

# Web Game Development

Use this skill when the real question is **"which upstream Three.js/browser game-development skill should own this task, and how do I get it installed?"**

This is a **routing pack**, not a reimplementation. The 19 real sub-skills live
upstream at [MengTo/Skills](https://github.com/MengTo/Skills/tree/main/agent-skills/game-development).
The job here is to:

1. classify the task honestly against the 19 sub-skills,
2. pick the single narrowest match (combine only when the task truly crosses a
   documented boundary),
3. fetch that sub-skill locally if it is not already installed,
4. sequence multi-skill work along the game lifecycle, and
5. route out to this repo's non-Three.js skills when they are the real owner.

Read [references/skill-routing-table.md](references/skill-routing-table.md) for
the full 19-skill decision table with upstream-grounded "use when" lines and
boundary notes.
Read [references/lifecycle-and-handoffs.md](references/lifecycle-and-handoffs.md)
for the prototype → systems → content → assets → feel → perf → QA → release
ordering and which sub-skills own each stage.
Read [references/route-outs.md](references/route-outs.md) before routing to
`unity-gamedev-skill-pack`, `game-performance-profiler`, `game-ci-cd-pipeline`,
`game-build-log-triage`, `game-demo-feedback-triage`, `steam-store-launch-ops`,
or `perfectpixel`.

## Explicit boundary against `unity-gamedev-skill-pack`

`unity-gamedev-skill-pack` curates external **Unity/C#** skill packs
(Addressables, Cinemachine, GAS, VContainer, UniTask, Wwise). This skill,
`web-game-development`, routes into the **Three.js / browser** game-development
family instead. If the engine is Unity or Unreal, stop here and use
`unity-gamedev-skill-pack` (or the engine-specific Unity/Unreal skills such as
`game-performance-profiler`, `game-ci-cd-pipeline`, `game-build-log-triage`
described in [references/route-outs.md](references/route-outs.md)). Do not
apply Three.js-authored sub-skill guidance to a Unity project or vice versa.

## When to use this skill

- The task is building, extending, or auditing a Three.js/browser action game
- You need to pick between two or more upstream game-development sub-skills
  and are not sure which one is narrowest
- The upstream sub-skill needed for the task is not yet installed locally
- You are sequencing a multi-stage slice (e.g. new enemy type touching content,
  rig, AI, combat, and VFX skills) and need the right order and boundaries
- You n
