How to use gsap 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 gsap

Run the install command

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

$npx skills add https://github.com/martinholovsky/claude-skills-generator --skill gsap

Fetches gsap from martinholovsky/claude-skills-generator 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/gsap

Restart Cursor to activate gsap. Access via /gsap 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.

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

1. Overview

This skill provides GSAP (GreenSock Animation Platform) expertise for creating smooth, professional animations in the JARVIS AI Assistant HUD.

Risk Level: LOW - Animation library with minimal security surface

Primary Use Cases:

HUD panel entrance/exit animations

Status indicator transitions

Data visualization animations

Scroll-triggered effects

Complex timeline sequences

2. Core Responsibilities

2.1 Fundamental Principles

TDD First: Write animation tests before implementation

Performance Aware: Use transforms/opacity for GPU acceleration, avoid layout thrashing

Cleanup Required: Always kill animations on component unmount

Timeline Organization: Use timelines for complex sequences

Easing Selection: Choose appropriate easing for HUD feel

Accessibility: Respect reduced motion preferences

Memory Management: Avoid memory leaks with proper cleanup

2.5 Implementation Workflow (TDD)

Step 1: Write Failing Test First

// tests/animations/panel-animation.test.ts import { describe, it, expect, vi, beforeEach, afterEach } from 'vitest' import { mount } from '@vue/test-utils' import { gsap } from 'gsap' import HUDPanel from '~/components/HUDPanel.vue' describe('HUDPanel Animation', () => { beforeEach(() => { // Mock reduced motion Object.defineProperty(window, 'matchMedia', { writable: true, value: vi.fn().mockImplementation(query => ({ matches: false, media: query })) }) }) afterEach(() => { // Verify cleanup gsap.globalTimeline.clear() }) it('animates panel entrance with correct properties', async () => { const wrapper = mount(HUDPanel) // Wait for animation to complete await new Promise(resolve => setTimeout(resolve, 600)) const panel = wrapper.find('.hud-panel') expect(panel.exists()).toBe(true) }) it('cleans up animations on unmount', async () => { const wrapper = mount(HUDPanel) const childCount = gsap.globalTimeline.getChildren().length await wrapper.unmount() // All animations should be killed expect(gsap.globalTimeline.getChildren().length).toBeLessThan(childCount) }) it('respects reduced motion preference', async () => { // Mock reduced motion enabled window.matchMedia = vi.fn().mockImplementation(() => ({ matches: true })) const wrapper = mount(HUDPanel) const panel = wrapper.find('.hud-panel').element // Should set final state immediately without animation expect(gsap.getProperty(panel, 'opacity')).toBe(1) }) })

Step 2: Implement Minimum to Pass

// components/HUDPanel.vue - implement animation logic const animation = ref<gsap.core.Tween | null>(null) onMounted(() => { if (!panelRef.value) return if (window.matchMedia('(prefers-reduced-motion: reduce)').matches) { gsap.set(panelRef.value, { opacity: 1 }) return } animation.value = gsap.from(panelRef.value, { opacity: 0, y: 20, duration: 0.5 }) }) onUnmounted(() => { animation.value?.kill() })

Step 3: Refactor Following Patterns

// Extract to composable for reusability export function usePanelAnimation(elementRef: Ref<HTMLElement | null>) { const animation = ref<gsap.core.Tween | null>(null) const animate = () => { if (!elementRef.value) return if (window.matchMedia('(prefers-reduced-motion: reduce)').matches) { gsap.set(elementRef.value, { opacity: 1 }) return } animation.value = gsap.from(elementRef.value, { opacity: 0, y: 20, duration: 0.5, ease: 'power2.out' }) } onMounted(animate) onUnmounted(() => animation.value?.kill()) return { animation } }

Step 4: Run Full Verification

# Run animation tests npm test -- --grep "Animation" # Check for memory leaks
