How to use git-city-3d-github-visualization 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 git-city-3d-github-visualization

Run the install command

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

$npx skills add https://github.com/aradotso/trending-skills --skill git-city-3d-github-visualization

Fetches git-city-3d-github-visualization from aradotso/trending-skills 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/git-city-3d-github-visualization

Restart Cursor to activate git-city-3d-github-visualization. Access via /git-city-3d-github-visualization in your agent's command palette.

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

git clone https://github.com/srizzon/git-city.git cd git-city npm install # Copy env template cp .env.example .env.local # Linux/macOS copy .env.example .env.local # Windows CMD Copy-Item .env.example .env.local # PowerShell npm run dev # → http://localhost:3001

Environment Variables

Fill in .env.local after copying:

Core Concepts

Building Metrics Mapping

Buildings are generated from GitHub profile data:

// lib/buildings.ts pattern interface BuildingMetrics { height: number; // Based on total contributions width: number; // Based on public repo count windowBrightness: number; // Based on total stars received windowPattern: number[]; // Based on recent activity pattern } function calculateBuildingMetrics(profile: GitHubProfile): BuildingMetrics { const height = Math.log10(profile.totalContributions + 1) * 10; const width = Math.min(Math.ceil(profile.publicRepos / 10), 8); const windowBrightness = Math.min(profile.totalStars / 1000, 1); return { height, width, windowBrightness, windowPattern: [] }; }

3D Building Component (React Three Fiber)

// components/city/Building.tsx pattern import { useRef } from 'react'; import { useFrame } from '@react-three/fiber'; import * as THREE from 'three'; interface BuildingProps { position: [number, number, number]; metrics: BuildingMetrics; username: string; isSelected?: boolean; onClick?: () => void; } export function Building({ position, metrics, username, isSelected, onClick }: BuildingProps) { const meshRef = useRef<THREE.Mesh>(null); // Animate selected building useFrame((state) => { if (meshRef.current && isSelected) { meshRef.current.rotation.y = Math.sin(state.clock.elapsedTime) * 0.05; } }); return ( <group position={position} onClick={onClick}> {/* Main building body */} <mesh ref={meshRef}> <boxGeometry args={[metrics.width, metrics.height, metrics.width]} /> <meshStandardMaterial color="#1a1a2e" /> </mesh> {/* Windows as instanced meshes for performance */} <WindowInstances metrics={metrics} /> </group> ); }

Instanced Meshes for Performance

Git City uses instanced rendering for windows — critical for a city with many buildings:

// components/city/WindowInstances.tsx pattern import { useRef, useEffect } from 'react'; import { InstancedMesh, Matrix4, Color } from 'three'; export function WindowInstances({ metrics }: { metrics: BuildingMetrics }) { const meshRef = useRef<InstancedMesh>(null); useEffect(() => { if (!meshRef.current) return; const matrix = new Matrix4(); const color = new Color(); let index = 0; // Calculate window positions based on building dimensions
