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 | $0.00036 | $0.00331 |
| Opus 5.5 | $0.00014 | $0.00132 |
| Sonnet 5.5 | $0.00007 | $0.00066 |
| Haiku 4.5 | $0.00004 | $0.00033 |
Grade A, and why
threejs-game-ui-designer 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 2mo 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.
What it actually says
Three.js Game UI Designer
Build interface states that support play and feel native to the game.
Read By Need
- UI implementation and state patterns:
references/ui-patterns.md. - Before claiming HUD, menu, responsive, or touch work complete:
references/quality-gates.md. - Generated 3D menu objects or diegetic props:
../../references/mint-mcp-assets.md.
Use authored HTML/CSS/SVG/Canvas or user-provided assets for ordinary flat UI. Use Mint MCP only when the live host exposes the required output. Never use another generation provider.
Workflow
- Inspect desktop/mobile screenshots and inventory gameplay, pause, settings, loading, fail/retry, win/milestone, and touch states.
- Prioritize survival/status, objective, feedback, then flavor.
- Replace utility cards with game-specific meters, clusters, badges, icons, alerts, reticles, and modal states.
- Keep dimensions stable; account for text fit, safe areas, touch targets, hover/pressed/focus/disabled states, and reduced motion.
- Drive UI from game state without duplicating simulation rules.
- Verify relevant states through real input at desktop and mobile sizes.
Final Response
Report states covered, UI intent, controls, screenshots, text-fit/overlap, safe-area/touch-target evidence, and remaining risks.
What ships with it
2 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.
