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.

SkillSpector: 1 finding, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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 | $0.00084 | $0.01831 |
| Opus 5.5 | $0.00034 | $0.00732 |
| Sonnet 5.5 | $0.00017 | $0.00366 |
| Haiku 4.5 | $0.00008 | $0.00183 |
Grade A, and why
threejs-game-director 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 29d 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 — 86 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Three.js Game Director
Own the end-to-end game outcome: a playable loop first, then the visual and interface depth the request actually asked for, then browser evidence that it works.
Scope
The user's own words set the bar. "Make a small arcade game" is not a request for the full premium pipeline — build the good version of what was asked and stop. "Premium", "AAA", "polished", "high-fidelity", "showcase", "release-ready", or "less basic" is that request, and at that bar a first playable slice is not done. "Less basic" specifically means the current visual level was rejected; treat it as the premium bar.
The user's scope, art style, constraints, and prior decisions override skill defaults. A narrow edit to a premium game remains a narrow edit. Make routine implementation calls yourself and complete authorized work before seeking a decision that only affects a later step. Ask only when a missing choice materially changes the requested result; continue independent work meanwhile. Until the requested bar is met, don't end a turn with a summary that announces the next step, an offer to continue, or a list of decisions that don't block the work; take the next step instead. End the turn when the work is done, or when only the user can unblock it.
Working style
Say in one sentence what you're about to do before your first tool call. While working, give a short update when you finish a phase, find something important, or change direction. Lead the final response with the outcome.
The lead owns shared interfaces, integration, and the final verification pass. Use available delegation tools for independent work that saves time or improves quality: asset generation alongside gameplay, or isolated UI work after the intent/state interface is defined. Normally use a lead plus up to two workers. Give each worker a task, separate file ownership, input/output contract, and acceptance criteria. Keep the immediate blocking integration work with the lead.
For substantial gameplay, graphics, or animation changes, one focused independent review can catch missed defects. Supply raw captures/code and the relevant rubric; ask for concrete defects rather than endorsement of the lead's score. Resolve findings without recursive review cycles. When delegation tools are absent, work directly.
What ships with it
6 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-game-director is a skill published in the GitHub repository majidmanzarpour/threejs-game-skills (2,600 stars, last pushed 1mo ago), licensed MIT. It adds 84 tokens to every session and 1,831 once invoked, about $0.0003 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 2026-08-30.
