What it does

Threejs Game UI Designer is an agent skill from mintdotgg/mint-threejs-skills. Design readable, responsive Three.js game HUDs, menus, overlays, touch controls, typography, safe areas, and game-state-driven interface feedback.

Its SKILL.md is about 380 tokens, which your agent loads only when the skill is triggered. The skill folder holds 3 other files, including reference files (for example `references/quality-gates.md` and `references/ui-patterns.md`).

It sits in Game Development, covering 3D graphics and WebGL. It works with Three.js. The repository describes itself as: Agent guidance for building polished Three.js apps and games with Mint MCP. The licence is MIT.

When your agent uses it

  • Tasks that involve 3D graphics and WebGL

Example prompts

  • “/threejs-game-ui-designer”

Workflow steps

6 steps, taken from the first numbered list in SKILL.md.

  1. Inspect desktop/mobile screenshots and inventory gameplay, pause, settings,
  2. Prioritize survival/status, objective, feedback, then flavor.
  3. Replace utility cards with game-specific meters, clusters, badges, icons,
  4. Keep dimensions stable; account for text fit, safe areas, touch targets,
  5. Drive UI from game state without duplicating simulation rules.
  6. Verify relevant states through real input at desktop and mobile sizes.

What it can do on your machine

Read from SKILL.md and the folder at commit de7af44. 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

Threejs Game UI Designer loads about 379 tokens when it runs, and up to ~2.3k if it reads all its reference files. Until then it costs about 43 tokens; SKILL.md has 162 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~43
When it runs · the whole SKILL.md, loaded when a task matches
~379
With references · SKILL.md plus every file in references/, read only if the agent opens them
~2.3k

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.

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

  1. Inspect desktop/mobile screenshots and inventory gameplay, pause, settings, loading, fail/retry, win/milestone, and touch states.
  2. Prioritize survival/status, objective, feedback, then flavor.
  3. Replace utility cards with game-specific meters, clusters, badges, icons, alerts, reticles, and modal states.
  4. Keep dimensions stable; account for text fit, safe areas, touch targets, hover/pressed/focus/disabled states, and reduced motion.
  5. Drive UI from game state without duplicating simulation rules.
  6. 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.
