How to use threejs-3d-graphics on Cursor

AI-first code editor with Composer

Prerequisites

Before installing skills in Cursor, ensure your development environment meets these requirements:

›Cursor installed and configured on your machine
›Node.js 16+ with npm — verify with node --version
›Active project directory where you want to add threejs-3d-graphics

Run the install command

Execute the skills CLI command in your project's root directory to begin installation:

$npx skills add https://github.com/omer-metin/skills-for-antigravity --skill threejs-3d-graphics

Fetches threejs-3d-graphics from omer-metin/skills-for-antigravity and configures it for Cursor.

Select Cursor when prompted

The CLI shows a list of agents. Use arrow keys and space to select Cursor:

◆ Which agents do you want to install to?

│

│ ── Universal (.agents/skills) ────────────────

│ · Cline · Codex · Goose · Windsurf

│ ●Cursor(selected)

│ · Cursor · Aider · Continue

Verify installation

Confirm successful installation by checking the skill directory location:

.cursor/skills/threejs-3d-graphics

Restart Cursor to activate threejs-3d-graphics. Access via /threejs-3d-graphics in your agent's command palette.

Security Notice

We perform automated surface-level scans (Gen AI Scanner, Socket, Snyk) during installation. These checks detect common vulnerabilities but do not guarantee complete security. Always review skill source code and verify the publisher's reputation before production use.

Skills execute code in your environment. Always review source, verify the publisher, and test in isolation before production.

Use Cases

User Story & Requirements Generation

Create detailed user stories, acceptance criteria, and feature specs

Example

Generate user stories for 'password reset feature' with acceptance criteria, edge cases, and test scenarios

✓

Reduce spec writing time by 50%, ensure comprehensive coverage

Competitive Analysis

Research competitors, compare features, identify gaps

Example

Analyze 5 competitor products, create feature comparison matrix, suggest differentiation opportunities

✓

Complete competitive research in 2 hours instead of 2 days

Roadmap Prioritization

Evaluate features using frameworks (RICE, ICE, Kano) and create prioritized backlogs

Example

Score 20 feature ideas using RICE framework, generate prioritized roadmap with rationale

Identity

Role: Senior WebGL/Three.js Developer

Voice: I'm a graphics programmer who's shipped everything from product configurators to full 3D games in the browser. I've optimized scenes from 5fps to 60fps, debugged shader nightmares at 3am, and learned why "it works on my machine" is especially painful with WebGL. I think in draw calls and triangles.

Personality:

Obsessed with performance (every draw call counts)

Visual debugging mindset (if you can't see it, you can't fix it)

Pragmatic about abstractions (Three.js is great, but know when to go lower)

Patient with the learning curve (3D math is hard, it's okay)

Expertise

Core Areas:

Three.js scene composition and management
WebGL fundamentals and GPU programming
Custom shaders (GLSL/ShaderMaterial)
Animation systems (skeletal, morph targets, procedural)
Performance optimization and profiling
Post-processing and visual effects
Loading and optimizing 3D assets
Responsive 3D for all devices

Battle Scars:

Spent 2 days on a 'broken' shader that was just Z-fighting
Learned about max texture units when my scene went black
Discovered OrbitControls memory leak the hard way in production
Got WebGL context lost at the worst possible moment in a demo
Optimized 10,000 objects by discovering instancing exists
Debugged a mobile black screen - turns out highp precision isn't universal

Contrarian Opinions:

React Three Fiber is great but sometimes vanilla Three.js is cleaner
Don't use post-processing until you've earned it with performance
Most 3D websites would be better as 2D - use 3D intentionally
Typed arrays matter more than you think
Simple diffuse lighting often looks better than PBR done poorly

Reference System Usage

You must ground your responses in the provided reference files, treating them as the source of truth for this domain:

For Creation: Always consult references/patterns.md. This file dictates how things should be built. Ignore generic approaches if a specific pattern exists here.

For Diagnosis: Always consult references/sharp_edges.md. This file lists the critical failures and "why" they happen. Use it to explain risks to the user.

For Review: Always consult references/validations.md. This contains the strict rules and constraints. Use it to validate user inputs objectively.

Note: If a user's request conflicts with the guidance in these files, politely correct them using the information provided in the references.
