What it does
Engine Selection is an agent skill from sickn33/agentic-awesome-skills. Selects game engines and frameworks by platform, genre, and architecture (full canvas shell vs hybrid DOM shell + guest viewport). Covers Phaser, PixiJS, Kaplay, Canvas/WebGL, Three.js, Babylon.js, Godot, Unity, Ink, Twine. Use when choosing a stack or comparing runtimes before implementation.
Its SKILL.md is about 1.2k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Game Development, covering Game development and 3D graphics and WebGL. It works with Godot and Three.js. The repository describes itself as: AAS Core is the local, agent-first control plane for complete catalog discovery, agent-owned selection, stack validation, and planning, backed by 2,400+ agentic skills. Includes… The licence is MIT.
When your agent uses it
- Choosing a stack
- Comparing runtimes before implementation
Example prompts
- “Use the engine-selection skill to select game engines and frameworks by platform, genre, and architecture (full canvas shell vs hybrid DOM shell +…”
- “/engine-selection”
Workflow steps
5 steps, taken from the first numbered list in SKILL.md.
- Platform: Web, mobile, PC, console, VR?
- Primary loop: Action/physics, turn-based, narrative branch, management/UI, hybrid?
- Presentation: Full-screen canvas, DOM/UI chrome, or both?
- Toolchain: No-build / ESM OK, or bundler + editor OK?
- Authoring: Code-only, or designers need Twine/Ink/Godot/Unity editors?
What it can do on your machine
Read from SKILL.md and the folder at commit 1e53ce2. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Engine Selection loads about 1.2k tokens when it runs. Until then it costs about 78 tokens; SKILL.md has 428 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Engine selection
Pick tools that match delivery target, interaction model, and team constraints. Engines serve the game type — not the reverse.
Fit questions (ask first)
- Platform: Web, mobile, PC, console, VR?
- Primary loop: Action/physics, turn-based, narrative branch, management/UI, hybrid?
- Presentation: Full-screen canvas, DOM/UI chrome, or both?
- Toolchain: No-build / ESM OK, or bundler + editor OK?
- Authoring: Code-only, or designers need Twine/Ink/Godot/Unity editors?
Architecture patterns
| Pattern | When | Notes |
|---|---|---|
| Full engine shell | Game is the canvas/scene | Phaser, Godot, Unity, Kaplay as app root |
| Renderer + custom logic | You want draw power, own gameplay | PixiJS, Three.js + your systems |
| Hybrid shell + guest | Dense UI/text + occasional skill-checks | DOM/app shell; mount canvas engines in modals/viewports only |
| Narrative runtime | Branching prose is the product | Ink, Twine; host chrome separately |
| Content-as-data | Levels/events authored as packs | JSON/YAML + thin loader; engine optional |
Web — decision tree
What type of game?
│
├── Mostly DOM / panels / forms / text UI
│ ├── + small arcade/spatial challenges
│ │ └── Hybrid: custom shell + guest
│ │ Raw Canvas/WebGL → Kaplay → Phaser → PixiJS
│ └── + branching story
│ └── Ink (inkjs) or Twine export → host in DOM
│
├── Full-screen 2D game
│ ├── Full gameplay features (scenes, physics, input)
│ │ └── Phaser 4 (or Kaplay if you want lighter/faster prototype)
│ └── Mostly rendering / custom systems
│ └── PixiJS 8 (or Raw Canvas/WebGL if tiny scope)
│
└── Full-screen 3D game
├── Full engine / physics / XR
│ └── Babylon.js
└── Rendering-focused / lighter
└── Three.jsQuick comparison (web & common exports)
| Tool | Type | Best for | Watch-outs |
|---|---|---|---|
| Raw Canvas / WebGL | 2D/low-level | Tiny games, learning, no framework tax | You own everything |
| Kaplay (ex-Kaboom) | 2D toolkit | Fast prototypes, jam games | Less “full product” structure than Phaser |
| Phaser 4 | 2D engine | Complete 2D features | Heavier; often bundled |
| PixiJS 8 | 2D renderer | Performance, custom game code | Not a full gameplay framework alone |
| Three.js | 3D renderer | Visuals, lightweight 3D | You add gameplay systems |
| Babylon.js | 3D engine | Fuller 3D + XR | Heavier than Three for simple scenes |
| Ink + inkjs | Narrative | Complex branching prose | Weak for real-time multi-entity sims |
| Twine / Twison / TweeJS | Narrative | Educator-friendly branches | Export/host glue; not a physics engine |
| Godot 4 | Full engine | 2D/3D indie, open source | Web export iteration cost |
| Unity | Full engine | Large teams, multi-platform | Heavy for simple web UI games |
Editor-first web shells (Construct, GDevelop) fit visual prototyping; weaker when you need versioned code-first content pipelines.

Non-web defaults (see also platform skills)
| Target | Lean toward |
|---|---|
| PC indie / open source | Godot 4 |
| PC large team / multi-platform | Unity |
| Mobile | See game-development/mobile-games (touch, stores, battery) |
| VR/AR | See game-development/vr-ar (+ Babylon/Three on web) |
Anti-patterns
| Don't | Do |
|---|---|
| Choose Unity/Godot for a form-heavy browser tool | Prefer DOM/hybrid |
| Force Ink to run real-time concurrent simulations | Use narrative tools for branches; custom/sim code for clocks & entities |
| Use Phaser as “the whole app” when the surrounding UI is HTML | Prefer a hybrid guest viewport |
| Optimize for WebGPU on day one | Ship WebGL; add WebGPU + fallback when needed |
When to Use
Use when choosing or comparing game engines/frameworks before implementation, especially for hybrid DOM+canvas or narrative-first products.
Limitations
- Does not replace platform skills (
game-development/web-games,game-development/pc-games, …). - Final choice still depends on team skill and shipping constraints.
- Stop and ask for clarification if required inputs, permissions, safety boundaries, or success criteria are missing.
