Build, debug, and verify Three.js browser games through Loom.

  • SKILL.md covers Choose the smallest skill, Delivery loop and Third-party material
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Threejs is an agent skill from valkor-ai/loom. Build, debug, and verify Three.js browser games through Loom. Use only when the request mentions Three.js, React Three Fiber, WebGL game work, or the active workspace declares a three, @react-three/fiber, or @react-three/drei dependency. Do not load for unrelated web projects.

Its SKILL.md is about 510 tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file.

It sits in Game Development, covering 3D graphics and WebGL. It works with Three.js and React. The repository describes itself as: Loop engineering for agentic software delivery. The licence is Apache-2.0.

When your agent uses it

  • Tasks that involve 3D graphics and WebGL

Example prompts

  • “/threejs”

What it can do on your machine

Read from SKILL.md and the folder at commit a30a7e6. 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 loads about 513 tokens when it runs. Until then it costs about 71 tokens; SKILL.md has 204 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~71
When it runs · the whole SKILL.md, loaded when a task matches
~513

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 Skills for Loom

Loom owns delivery state, task planning, repair, and handoff. Start non-trivial work through @loom plan; treat the specialist skills below as technical and verification guidance, not as an alternative workflow.

Choose the smallest skill

WorkSkill
Game design, core loop, input, camera, physics, or game feelthreejs-gameplay-systems
Models, materials, shaders, lighting, or render qualitythreejs-aaa-graphics-builder
HUDs, menus, overlays, touch controls, or responsive game UIthreejs-game-ui-designer
Blank canvas, runtime errors, asset loading, input, or performancethreejs-debug-profiler
Playtesting, screenshots, canvas diagnostics, or release checksthreejs-qa-release
Explicit 3D, image, or audio asset generationthreejs-3d-generator, threejs-image-generator, or threejs-audio-generator

Do not load every specialist for a small fix. Browser games with visual or interactive acceptance criteria should finish with the relevant browser evidence recorded in the Loom task result.

Delivery loop

For a new game or a substantial change, begin in the project root:

text
@loom plan Build a Three.js game with a playable movement loop and verified browser controls
@loom continue

Run the project's build and focused behavior checks first. Use canvas inspection, screenshots, or playtests only when they are relevant to the task. When a specialist skill recommends a workflow that conflicts with a Loom MCP request, follow the MCP request.

Third-party material

The specialist skill directories were imported from an MIT-licensed upstream skill pack. Its license is retained in UPSTREAM_LICENSE.
