Three.js Game Skills is a collection of agent skills for creating playable browser games with Three.js, a JavaScript library for rendering interactive 3D graphics. It is for users building games with gameplay, graphics, interfaces, generated assets, debugging, and release checks, with bundled Vite, TypeScript, and Three.js materials plus testing templates. The catalogue entries are the skills and instruction that coordinate these parts of the game-building workflow.
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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00109 | $0.02409 |
| Opus 5 | $0.00055 | $0.01205 |
| Sonnet 5 | $0.00022 | $0.00482 |
| Haiku 4.5 | $0.00011 | $0.00241 |
Grade A, and why
threejs-3d-generator 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 5d 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 — 121 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Three.js 3D Generator
Production 3D assets for browser games, prepared for Three.js. Provider: Tripo.
Resolve <this-skill-dir> from the actual loaded skill file. Resolve sibling skills beside it first, then use the runner's discovered paths. Do not mix installed versions or assume a particular home directory.

API key
The script reads --api-key or TRIPO_API_KEY. Keys never go in skill files, game code, or reports.
python3 <this-skill-dir>/scripts/threejs_3d_asset.py probe # TRIPO_API_KEY=SET|MISSING
Keys defined only in a shell profile can be absent from the process env. If the plain probe unexpectedly prints MISSING, use threejs-game-director/scripts/probe_asset_credentials.sh, which sources the profile and probes all three providers at once.
Download URLs expire quickly — download immediately after a task succeeds.
Commands
python3 <this-skill-dir>/scripts/threejs_3d_asset.py --help
Text to 3D, the default for a premium hero model:
python3 <this-skill-dir>/scripts/threejs_3d_asset.py text \
--prompt "game-ready sci-fi hover bike, sleek armored panels, strong readable silhouette, layered hard-surface detail, PBR materials, clean topology, centered pivot, front facing, no text" \
--model-version v3.1-20260211 --texture-quality detailed --geometry-quality detailed \
--checkpoint artifacts/hover-bike-job.json \
--wait --download --out-dir assets/models/hover-bike
Image to 3D from a generated concept:
python3 <this-skill-dir>/scripts/threejs_3d_asset.py image \
--image assets/concepts/hover-bike-front.png --model-version v3.1-20260211 \
--enable-image-autofix --texture-alignment original_image --texture-quality detailed \
--wait --download --out-dir assets/models/hover-bike
What ships with it
5 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.
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-3d-generator is a skill published in the GitHub repository majidmanzarpour/threejs-game-skills (1,955 stars, last pushed 6d ago), licensed MIT. It adds 109 tokens to every session and 2,409 once invoked, about $0.0005 per session on Opus 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 2026-08-30.

Implement game audio practice — bus/mixer architecture and gain in decibels, ducking (sidechain), adaptive/dynamic music via layering and re-sequencing, SFX variation, and beat synchronization. Engine-neutral. Use when the user mentions audio mixing, audio buses, adaptive/dynamic music, ducking, SFX variation, music…

Build deterministic, editable, free-viewpoint Three.js worlds from text or structured briefs. Use for cinematic 3D terrain, semantic regions, procedural biomes, explicit landmarks, environmental scattering, camera fly-throughs, world diagnostics, or requests for a real 3D environment rather than generated 2D footage.…
