What it does

New Experiment is an agent skill from Tresjs/tres. Create a new experiment in TresJS Lab with all necessary files

Its SKILL.md is about 780 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Game Development, covering 3D graphics and WebGL and Shaders. It works with Vue.js, Vite and Three.js. The repository describes itself as: Declarative ThreeJS using Vue Components. The licence is MIT.

When your agent uses it

Tasks that involve 3D graphics and WebGL
Tasks that involve Shaders

Example prompts

“/new-experiment”

Workflow steps

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

Parse arguments: Extract experiment name from $ARGUMENTS. If second argument is shaders or true, enable shader support.
Convert naming: Convert kebab-case to PascalCase for component naming (e.g., wobble-sphere → WobbleSphere).
Create markdown file: Create apps/lab/content/experiments/{experiment-name}.md with frontmatter
Create component directory: apps/lab/app/components/{experiment-name}/
Create index.global.vue
Create experiment component: The{PascalCaseName}.vue with basic structure.
If shaders enabled

What it can do on your machine

Read from SKILL.md and the folder at commit 443197b. 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 (its code samples are yaml, vue and bash).
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

New Experiment loads about 782 tokens when it runs. Until then it costs about 19 tokens; SKILL.md has 205 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~19
When it runs · the whole SKILL.md, loaded when a task matches: ~782

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.

New Experiment

Create a new experiment in the TresJS Lab app with all necessary files and structure.

Steps

Parse arguments: Extract experiment name from $ARGUMENTS. If second argument is shaders or true, enable shader support.
Convert naming: Convert kebab-case to PascalCase for component naming (e.g., wobble-sphere → WobbleSphere).

Create markdown file: Create apps/lab/content/experiments/{experiment-name}.md with frontmatter:

yaml

---
title: {Experiment Title}
author: {your-github-username}
description: {Brief description}
thumbnail: /experiments/{experiment-name}.png
tags: []
date: {current-date}
lastUpdated: {current-date}
---

Create component directory: apps/lab/app/components/{experiment-name}/

Create index.global.vue:

vue

<script setup lang="ts">
// TODO: Implement experiment logic
</script>

<template>
  <TresCanvas>
    <TresPerspectiveCamera :position="[0, 0, 10]" :look-at="[0, 0, 0]" />
    <{ExperimentName}The{PascalCaseName} />
    <OrbitControls />
    <TheScreenshot />
  </TresCanvas>
</template>

Create experiment component: The{PascalCaseName}.vue with basic structure.

If shaders enabled:

Create shaders/ directory inside component folder

Create shaders/vertex.glsl:

glsl

uniform float uTime;
uniform vec2 uResolution;

void main() {
  vec4 modelPosition = modelMatrix * vec4(position, 1.0);
  vec4 viewPosition = viewMatrix * modelPosition;
  vec4 projectedPosition = projectionMatrix * viewPosition;
  gl_Position = projectedPosition;
}

Create shaders/fragment.glsl:

glsl

uniform float uTime;
void main() {
  gl_FragColor = vec4(1.0, 0.0, 0.0, 1.0);
}

Update The{PascalCaseName}.vue:

vue

<script setup lang="ts">
import vertexShader from './shaders/vertex.glsl';
import fragmentShader from './shaders/fragment.glsl';

const uniforms = {
  uTime: { value: 0 },
  uResolution: { value: new Vector2(window.innerWidth, window.innerHeight) },
}
</script>

<template>
 <TresMesh>
   <TresPlaneGeometry />
   <TresShaderMaterial :uniforms="uniforms" :vertex-shader="vertexShader" :fragment-shader="fragmentShader" />
 </TresMesh>
</template>

Examples

bash

# Basic experiment without shaders
/new-experiment my-cool-effect

# Experiment with shader support
/new-experiment wobble-sphere shaders

Considerations

Use kebab-case for file/folder names
Use PascalCase for component names
Component prefix matches experiment folder name (e.g., WobbleSphereTheWobbleSphere)
Add appropriate tags in frontmatter (e.g., 'shaders', 'glsl', 'particles', 'basic')
Markdown content can be filled in later - only create frontmatter
For shader experiments, include basic uniforms for time-based animations

Can I use New Experiment in Cursor, Gemini CLI or GitHub Copilot?

Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add Tresjs/tres --skill new-experiment -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/new-experiment, .gemini/skills/new-experiment, .github/skills/new-experiment and .opencode/skills/new-experiment in your project.

What does New Experiment need to run?

SKILL.md names no scripts, command-line tools or credentials: New Experiment is instructions for the agent only.

Does New Experiment access the network?

SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
