What it does
Threejs Gameplay Systems is an agent skill from mintdotgg/mint-threejs-skills. Design and implement playable Three.js game loops, architecture, controls, cameras, physics, levels, encounters, audio hooks, feedback, and game feel.
Its SKILL.md is about 680 tokens, which your agent loads only when the skill is triggered. The skill folder holds 45 other files, including scripts, reference files and assets (for example `assets/threejs-vite-game/package.json`, `assets/threejs-vite-game/playwright.config.ts` and `assets/threejs-vite-game/src/assets/gltf-runtime.ts`).
It sits in Game Development, covering 3D graphics and WebGL and Game design. 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
- Tasks that involve Game design
Example prompts
- “/threejs-gameplay-systems”
Requirements
- Python 3
- Node.js
Workflow steps
7 steps, taken from the first numbered list in SKILL.md.
- Inspect scripts, dependencies, loop ownership, input, camera, state, entities,
- Define the player promise, primary verb, objective, pressure, reward,
- Plan the first playable space or encounter: start, decision, threat, reward,
- Choose small ownership boundaries such as core, game, entities,
- Implement in playable increments: input, state, entity, collision/physics,
- Tune movement, camera, timing, difficulty, feedback, and restart through
- Verify build, browser rendering, real input, objective progress, and
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
Ships 1 file in scripts/ (TypeScript, from the files we listed), which the agent can run.
Shell commands in SKILL.md call:
python3
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 Gameplay Systems loads about 677 tokens when it runs, and up to ~10k if it reads all its reference files. Until then it costs about 44 tokens; SKILL.md has 281 words of instructions outside code blocks.
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); the scripts in this folder are not scanned.

Three.js Gameplay Systems
Create a playable, maintainable loop with clear ownership and responsive controls.
Read By Need
- Always for implementation:
references/gameplay-workflows.md. - New games, major loop changes, levels, encounters, progression, or difficulty:
references/game-design-level-design.md. - Physics or collision-heavy work:
references/physics-engine-selection.md. - Model axes, constrained motion, multiple moving actors, or terrain queries:
../../references/spatial-contracts.md. - Feel, impact, juice, or polished gameplay:
references/game-feel.md. - Before claiming broad gameplay complete:
references/quality-gates.md. - Generated audio or 3D gameplay assets:
../../references/mint-mcp-assets.md.
Workflow
- Inspect scripts, dependencies, loop ownership, input, camera, state, entities, UI, diagnostics, and current gameplay.
- Define the player promise, primary verb, objective, pressure, reward, fail/retry path, skill expression, and non-goals.
- Plan the first playable space or encounter: start, decision, threat, reward, escalation, recovery, and landmarks.
- Choose small ownership boundaries such as
core,game,entities,systems,assets,ui, andtests. - Implement in playable increments: input, state, entity, collision/physics, feedback, HUD/audio event, and diagnostics.
- Tune movement, camera, timing, difficulty, feedback, and restart through short play loops.
- Verify build, browser rendering, real input, objective progress, and fail/retry when relevant.
Gameplay code emits audio events. Mint-produced audio files belong in a stable runtime asset matrix; Mint MCP calls never belong in browser code.
New-Game Scaffold
python3 <this-skill-dir>/scripts/create_threejs_game.py ./my-gameUse --force only when overwriting the target is intended.
Technical Defaults
- TypeScript, Vite, and Three.js modules.
- Custom collision for simple arcade triggers; Rapier for robust rigid-body gameplay; cannon-es only when its smaller JavaScript footprint is useful.
- Fixed-step simulation for physics and seeded randomness for deterministic QA.
- Shared resources, explicit update order, and allocation-light hot paths.
- Web Audio for playback; Mint MCP for generated production audio.
Final Response
Report player-facing behavior, controls, design/level decisions when relevant, architecture, tuned values, verification evidence, assets, and remaining edge cases.
