awesome-gamedev-agent-skills is a collection of 73 instruction files that give AI coding agents specialized guidance for game development with engines and frameworks such as Godot, Unity, Unreal, and Phaser. It helps agents choose relevant engine and task guidance while building games. The catalogue entries are the collection's skills and plugins for agents including Claude Code, Cursor, Codex, and Gemini CLI.
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.

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 | $0.00117 | $0.02256 |
| Opus 5.5 | $0.00047 | $0.00902 |
| Sonnet 5.5 | $0.00023 | $0.00451 |
| Haiku 4.5 | $0.00012 | $0.00226 |
Grade A, and why
threejs-gltf-loading 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 2d 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.
How it starts
The opening of the file, as written. The whole thing — 203 lines — stays where its author put it; the contents beside it link to each section on GitHub.
three.js glTF Loading
Load .gltf/.glb models and play their animations in three.js, including
compressed geometry (DRACO/Meshopt) and textures (KTX2). Patterns target
r186; preserve an existing project's pinned release unless migration is requested.
When to use
- Use to import a 3D model, add it to the scene, inspect its node hierarchy, and
play baked/skinned animation clips with an
AnimationMixer. - Use when files are
.gltf/.glb, or code importsGLTFLoader/DRACOLoader/KTX2Loaderfromthree/addons/loaders/....
When not to use: creating the renderer/camera/loop → threejs-scene-setup.
Tuning surface look, lights, or shadows on the loaded model →
threejs-materials-lighting. Authoring/exporting the model itself (Blender) is out
of scope; prefer glTF over OBJ/FBX for runtime.
Core workflow
- Why glTF. It's a transmission format: binary vertex data, PBR materials, and animations are ready to render with minimal parsing. Prefer it over OBJ (no scene graph, no animation) and FBX (heavy) for the web.
- Load with
GLTFLoader.loader.load(url, onLoad, onProgress, onError). The resultgltfhasgltf.scene(theObject3Droot),gltf.animations(AnimationClip[]),gltf.cameras, andgltf.asset. - Add
gltf.sceneto your scene and frame it. Inspect the hierarchy withtraverse/getObjectByNameto find the parts you'll control. - Play animations with an
AnimationMixer. One mixer per animated root;mixer.clipAction(clip).play(); advance withmixer.update(delta)every frame. - Decode compressed assets. Attach a
DRACOLoader, aKTX2Loader, and/or the Meshopt decoder so DRACO meshes, KTX2 textures, and meshopt-compressed buffers load. Since r185 the DRACO and KTX2 loaders find their bundled decoder files on their own. - Validate changed glTF files when the project already has the tool. Run
gltf-transform validate path/to/model.glbfor each changed.gltfor.glb; fix reported errors before loading. - Verify what loaded — log the scene graph and
gltf.animations, and confirm the model is visible (right scale, lit) and the clip actually plays.
What ships with it
1 file 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.

threejs-gltf-loading is a skill published in the GitHub repository gamedev-skills/awesome-gamedev-agent-skills (4,867 stars, last pushed 3d ago), licensed Apache-2.0. It adds 117 tokens to every session and 2,256 once invoked, about $0.0005 per session on Opus 5.5. 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 2026-09-03.
Other skills, from other repositories
editor-session-quit
Save and quit an editor that a CLI session started (unity-mcp-cli exec, open --headless). Needs the session lease nonce; an editor the user opened is never closed. Used by unity-mcp-cli close.
screenshot-game-view
Capture a screenshot of the Unity Editor's Game View by reading its internal render texture directly. Image size matches the current Game View resolution; the tool corrects Y-flip on DirectX / Metal so the output is always upright. Requires an open Game View window.
dialogue-manager
Use when using the Dialogue Manager addon — .dialogue files with titles, responses, conditions and mutations, runtime balloons, and C# support.
event-bus
Use when implementing decoupled communication between nodes — global EventBus autoload with typed signals.
physics-system
Use when working with physics bodies, collision shapes, raycasting, areas, rigid bodies, ragdolls, soft bodies, Jolt physics, and physics interpolation in Godot 4.3+.
biome-detail-tuning
Configure and tune Unity Terrain detail (grass/flower/fern) placement for MapGenerator biomes using prefabs and noise-driven clustering. Covers the full workflow from prefab selection through noise parameter tuning to external audit verification and performance optimization. Use when: setting up detail for any biome…
