GreenSock Official GSAP Skills Test - Enabling AI to Generate Professional-Grade Front-End Animations

Today I'm sharing some things suitable for front-end animation.

Normally let AI When you try to create front-end animations, either the animation doesn't understand what you're saying, or the result is a complete mess.

This GitHub project called Gsap-skills solves this problem, allowing... AI Know how to generate page animations correctly.

Gsap-skills It is the GSAP coding skills set officially maintained by GreenSock, targeting Codex,Claude Code, etc. AI AgentAfter installation,Agent It reads the rules, examples, and common error descriptions provided by GreenSock when writing animation code.

Project address: https://github.com/greensock/gsap-skills

AI Models typically know the basic syntax of GSAP, but they are prone to several types of problems when faced with complex animations:

• It uses outdated installation methods such as the old Club GSAP, private npm repository, and authentication token.
• The animation was stitched together using multiple delays, without using a Timeline.
• Using properties such as top, left, and width to create translation animations triggers frequent layout calculations.
• Leave Tween or ScrollTrigger after components such as React and Vue are uninstalled.
• Attach the ScrollTrigger to a child Tween inside the Timeline.
• The plugin was not registered. It worked fine in the development environment, but was deleted by tree shaking after the production build.
• Ignoring prefers-reduced-motion means no animation reduction is applied for users sensitive to motion sickness.

Gsap-skills breaks down animation capabilities into 8 parts:

1. gsap-core: Handles basic animations

2. gsap-timeline: Arranges the animation order

3. gsap-scrolltrigger: Makes the animation scroll.

4. gsap-plugins: Invokes advanced plugins

5. gsap-utils: Handles animation values

6. gsap-react: Solves React integration issues

7. gsap-performance: Reduce animation stuttering

8. gsap-frameworks: Adapts to Vue, Nuxt, and Svelte

Gsap-skills Write these rules into the proxy context so that the model actively adopts the official rules when generating code.recommendWriting style.

Gsap-skills Suitable for writing this type of code:

• React, Vue, or Nuxt page animations
• ScrollTrigger: Scrolling narrative and fixed chapters
• SVG paths, MorphSVG, DrawSVG animations
• Flip layout switching and draggable interaction
• SplitText and ScrambleText text animations
• Complex timelines requiring pause, reverse playback, jump, and dynamic control

Case 1: gsap-core: Orbital Launch Pad

Prompt words：

Invoke the `gsap-core` skill to create a complete front-end project named `gsap-core-launchpad` in the current workspace.

The technology stack uses Vite, native HTML, CSS, and JavaScript. gsap is installed via npm, without using a CDN.

Create an animated page for an "orbital launch pad" so that the effect can be directly displayed in the browser. The functions used are gsap.to(), gsap.from(), gsap.fromTo(), stagger, transform, autoAlpha, ease, and gsap.matchMedia().

The page needs to include:

1. The dark space control console interface features the probe, a circular orbit, and 12 orbital scales in the center.

2. When the page opens, the title, status data, and operation buttons will appear sequentially from the bottom.

3. The 12 track scales are lit up sequentially using stagger.

4. After clicking "Start Detector", the detector will accelerate and fly out horizontally, while scaling, rotating and fading out.

5. Click "Reset" to restore the initial state, and you can play it repeatedly.

6. Provides three speed buttons: "Smooth", "Standard", and "High Speed".

7. Desktop and mobile devices use different displacement distances via gsap.matchMedia().

8. When the system prefers-reduced-motion is enabled, large-scale motion is canceled, and only a brief fade-in is retained.

9. Use x, y, scale, and rotation for translation animations, but not top, left, width, and height.

10. Use autoAlpha for fade-out to prevent transparent elements from continuing to block clicks.

It needs to have complete navigation, page title, animated stage, operation area, and capability description area. The page needs to be responsive and adapted to mobile devices.

Create package.json, index.html, src/main.js, src/style.css, and README.md directly. Do not just return code snippets.

Execute after completion:

npm install

npm run build

After successful build, start the development server, return a local address that can be opened in a browser, and explain the startup command.

You can understand the case study content simply by opening it, and you can see the GSAP effect by clicking.

Overall, this case is ready to be used directly in the accompanying demonstration. The visual completeness, GSAP syntax, and interaction loop are all satisfactory, and no issues preventing its use were found.

Case 2: gsap-timeline: Opening sequence

Prompt words：

Invoke the `gsap-timeline` skill to create a complete front-end project named `gsap-timeline-show` in the current workspace.

The technology stack uses Vite, native HTML, CSS, and JavaScript, and gsap is installed via npm.

Create an "Electronic Music Performance Opening" page that uses a complete animation to visually demonstrate the GSAP Timeline, position parameters, tags, nested timelines, and playback controls.

The animation process includes:

1. The two screens on the left and right sides open to the sides.

2. A stage grid and a record turntable appear.

3. The eight volume bars popped up in sequence.

4. The performance title is displayed in two lines; enter from the bottom.

5. The date, venue, and subtitle then appear.

6. The turntable begins to rotate, and the volume bar continues to jump.

7. Finally, the screen focuses on the complete performance poster.

Implementation requirements:

1. Use gsap.timeline({ defaults: … }) to uniformly set duration and ease.

2. Use positional parameters such as "<", ">", and "+=0.2" to control parallel and interleaved relationships.

3. Add tags such as open, pulse, title, and hold.

4. Multiple delays cannot be used to stitch together an animation.

5. Add "Play", "Pause", "Reverse", "Replay", and "Jump to Title" buttons.

6. Add a draggable progress bar to allow manual control of the Timeline progress.

7. The page displays the current playback time and total duration.

8. Nested Timelines can be used to manage title animations or volume bar animations.

9. When the system has prefers-reduced-motion enabled, the final status will be displayed directly.

10. Use only transform, opacity, and autoAlpha for animation.

Create a complete project file directly. The page needs to have clear stage effects and cannot just display code or parameter panels.

After completion, run `npm install` and `npm run build`. Once the build is successful, start the development server and return the browser address.

It allows you to visually see the four animation stages and play, pause, reverse, jump, and drag the progress.
With high visual recognizability, the stage, record player, volume column, and fluorescent colors create a unified electronic performance style.

Case 3: gsap-scrolltrigger: Deep-sea exploration rolling

Prompt words：

Invoke the `gsap-scrolltrigger` skill to create a complete front-end project named `gsap-scrolltrigger-ocean` in the current workspace.

The technology stack uses Vite, native HTML, CSS, and JavaScript. Install gsap via npm, import ScrollTrigger from gsap/ScrollTrigger, and explicitly call gsap.registerPlugin(ScrollTrigger).

Create a scrolling narrative page for a "Deep-Sea Exploration Mission". The page should contain at least 4 chapters:

1. The submarine leaves the sea.

2. Descend to the photosphere.

3. Discovery of deep-sea creatures.

4. Arrive at the underwater hydrothermal vent.

The scrolling effect needs to meet the following requirements:

1. The page has sufficient scroll distance.

2. Once you enter the story area, the main screen will be fixed.

3. The submarine, depth numbers, speech bubbles, background layers, and chapter text change as you scroll.

4. The depth gradually increases from 0 meters to 6000 meters.

5. Use autoAlpha, scale, and y when switching chapters.

6. The scrolling progress and the current chapter are displayed on the right.

7. Use scrub: 1 to make the animation progress follow the scrolling.

8. Use pin: true and start: "top top".

9. You can use snap to bring the scrolling position closer to the chapter position after it stops.

10. ScrollTrigger should only be attached to the top-level Timeline, not to inner child Tween.

11. Do not configure toggleActions at the same time as using scrub.

12. Do not listen to window.scroll.

13. When the system has prefers-reduced-motion enabled, disable the fixed and scrolling linkage, and change the 4 chapters to normal vertical content.

The deep-sea environment on the page can be created using CSS graphics, bubbles, beams of light, and layered backgrounds; it cannot simply be text moving up and down.

Create a complete project file and execute `npm install` and `npm run build`. After a successful build, start the development server and return to the local access address.

The desktop version features a complete scrolling narrative, with the 6000-meter depth, chapter text, submarine, ocean background, and right-side progress changing synchronously, making the scrolling relationships clear.

The narrative is carried out through depth figures, submarine proportions, the interplay of light and shadow in the seawater, and the underwater topography, without any irrelevant special effects.

Case 4 gsap-plugins: Disc library layout variation

Prompt words：

Invoke the `gsap-plugins` skill to create a complete front-end project named `gsap-flip-records` in the current workspace.

The technology stack uses Vite, native HTML, CSS, and JavaScript. GSAP is installed via a public npm package; private npm repositories, Club GSAP, or authentication tokens are not used.

Use the Flip plugin to create a "Record Collection Library" page.

The page contains 8 album cards with different visual styles. Each card includes the cover, album name, artist, and duration. The cover must be a complete image and cannot use blank placeholders.

Three operations are provided:

1. Switch to a three-column grid.

2. Switch to a single-column playlist.

3. Randomly adjust the order of the records.

Implementation requirements:

1. Import Flip from gsap/Flip.

2. Call gsap.registerPlugin(Flip).

3. Use Flip.getState() to save the card state before each switch.

4. Modify the container layout or DOM order.

5. Use Flip.from() to complete the position and size transition.

6. Maintain the continuity of text and cover during card movement.

7. The buttons in the current layout need to have a clear selected state.

8. Mobile GridautomaticChange it to a single column or a double column.

9. When the system enables prefers-reduced-motion, the layout switch is completed immediately.

10. Do not manually calculate the left, top, or width animation for each card.

The page needs to resemble an active music product, not a rudimentary test page for the Flip API.

Create the project file directly, then execute `npm install` and `npm run build`. After a successful build, start the development server and return the access address.

The grid toggle list, random sorting, and album selection visually demonstrate FLIP's purpose, and the overall visual quality is very high.

Case 5: gsap-utils: Signal mixing console

Prompt words：

Invoke the `gsap-utils` skill to create a complete front-end project named `gsap-utils-tuner` in the current workspace.

The technology stack uses Vite, native HTML, CSS, and JavaScript, and gsap is installed via npm.

Create an interactive "signal mixing console" page to visually demonstrate the numerical processing capabilities of gsap.utils.

In the center of the page is a horizontal signal track with nine markings. Users can drag the slider, click on the track, or click on "Random Signal".

The interaction process requires the use of:

1. gsap.utils.clamp(), which limits the input range to 0 to 1000.

2. `gsap.utils.snap()` snaps numbers to multiples of 125.

3. gsap.utils.normalize() converts the result to 0 to 1.

4. gsap.utils.mapRange() maps the progress to the horizontal position and rotation angle of the marker.

5. gsap.utils.interpolate() changes the marker color and background color according to the progress.

6. gsap.utils.wrap() makes the "previous channel" and "next channel" loop at the boundary.

7. gsap.utils.random() generates random channel values that have already been snapped.

8. `gsap.utils.toArray()` retrieves all track ticks.

The page needs to be displayed in real time:

– Original input value

– value after clamping

– Value after snap

– normalize results

– The pixel position obtained by mapRange

– Current channel name

When numerical values change, the track markers need to move smoothly, and the scale should light up synchronously. The track range should be recalculated after the window size changes.

When the system has prefers-reduced-motion enabled, it updates the position directly without playing easing motion.

Create a complete project and execute `npm install` and `npm run build`. After a successful build, start the development server and return the browser address.

It can be opened directly, is interactive, and provides corresponding numerical changes and animation feedback.

Dragging, clicking tracks, random signals, and channel switching all drive the animation correctly. The visual direction is very consistent; the mixing console metaphor and numerical processing theme fit together, avoiding the common template-like card feel.

Case 6 gsap-react: The notification center can be uninstalled.

Prompt words：

Invoke the `gsap-react` skill to create a complete React frontend project named `gsap-react-notifications` in the current workspace.

The technology stack uses Vite, React, CSS, gsap, and @gsap/react. Dependencies are installed via npm, without using a CDN.

Create a "Real-time Notification Center" page. The page should display two separate NotificationPanel components simultaneously, allowing for intuitive verification of animation scope and uninstallation cleanup.

Each component contains:

1. A status indicator light.

2. Three notification cards.

3. "Receive New Messages" button.

4. "Clear Messages" button.

5. The current mounting status of the component.

The parent component provides the following operations:

1. Uninstall the left-hand component separately.

2. Uninstall the components on the right separately.

3. Remount the component.

4. Simultaneously replay the entrance animations of both components.

GSAP implementation requirements:

1. Import useGSAP from @gsap/react.

2. Call gsap.registerPlugin(useGSAP) outside the component.

3. Each NotificationPanel uses a separate root ref.

4. The scope must be configured for useGSAP, and selectors within a component can only hit the current component.

5. Notification cards are accessed sequentially using stagger.

6. Status indicator lights use scale and autoAlpha animation.

7. The animation callback created after clicking must use contextSafe.

8. You are not allowed to use document.querySelector() to manipulate elements inside a component.

9. After the component is uninstalled, useGSAP will handle the rest. automatic Revert animation.

10. A brief mount and cleanup log is displayed on the page, making the uninstallation results readily visible.

11. When the system has prefers-reduced-motion enabled, it only updates the status and does not play large animations.

The page needs to have a complete product interface and a responsive layout. The animations of the two components must not affect each other.

Write the necessary files directly to your project file, then execute `npm install` and `npm run build`. After a successful build, start the development server and return to your local machine.

The core capabilities are fully demonstrated, with actionable front-end feedback for scope isolation, event animation, and component uninstallation and cleanup.

Case 7: GSAPA Performance: High-Frequency Control Surface

Prompt words：

Invoke the `gsap-performance` skill to create a complete front-end project named `gsap-performance-field` in the current workspace.

The technology stack uses Vite, native HTML, CSS, and JavaScript, and gsap is installed via npm.

Create a "High-Frequency Signal Control Plane" page. The main area is a grid containing 64 signal nodes, with a circular scanning module in the center.

Interactive effects:

1. The scanning module smoothly follows the pointer as it moves within the control plane.

2. The scanning module rotates slightly according to the lateral position.

3. The page displays x, y and rotation angles in real time.

4. After clicking "Batch Pulse", 64 nodes will light up sequentially from the center outwards.

5. After clicking "Return to Center", the scanning module will smoothly return to the center.

Performance requirements:

1. Use gsap.quickTo() to create reusable Tweens for x, y, and rotation respectively.

2. In pointermove, only call the function returned by quickTo; do not continuously create gsap.to().

3. Use x, y, and rotation to move objects; do not use top or left.

4. Node pulses use Tween and stagger once, without setting a delay for each node individually.

5. Only set will-change for continuously moving scanning modules.

6. Pointer boundary information is read in pointerenter or ResizeObserver to avoid repeatedly reading the layout every frame.

7. Do not alternate between reading layouts and writing styles in the same loop.

8. Pause unnecessary animations when the page is hidden or the user leaves.

9. When the system enables prefers-reduced-motion, pointer following is disabled, and only the static state is retained.

10. The mobile app supports touch clicks and provides an operable center button.

The page needs to visually demonstrate the smooth performance of quickTo and batch stagger, while also providing a concise performance description area.

Create a complete project by executing `npm install` and `npm run build`. After a successful build, start the development server and return the access address.

The implementation is solid, and the presentation looks great. When the mouse pointer moves across the control panel, the scanning module follows smoothly and in real-time.

Case 8 gsap-frameworks: Vue dynamic poster wall

Prompt words：

Invoke the `gsap-frameworks` skill to create a complete Vue 3 front-end project named `gsap-vue-gallery` in the current workspace.

The technology stack uses Vite, Vue 3 Composition API, CSS, and gsap. gsap is installed via npm, without using a CDN.

Create a "Dynamic Poster Wall" page. The parent component renders two MotionGallery child components simultaneously to display the Vue lifecycle, animation scope, and uninstallation cleanup.

Each MotionGallery contains:

1. Four poster cards.

2. A status indicator that is currently playing.

3. "Rearrange" button.

4. "Play In" button.

5. Current mount status.

The parent component provides:

1. Uninstall the poster wall on the left.

2. Uninstall the poster wall on the right.

3. Remount the corresponding component.

4. The component mounting and cleanup history is displayed at the bottom of the page.

Implementation requirements:

1. Create the GSAP animation in onMounted().

2. Each component uses a separate root ref.

3. Use gsap.context() and make the root ref the selector scope.

4. Poster cards are accessed sequentially using stagger.

5. When you click on a poster, the current card will be enlarged, while the autoAlpha of other cards will be reduced.

6. Tween created after the event is triggered needs to be added to the Context, or killed separately during uninstallation.

7. Call ctx.revert() in onUnmounted().

8. Global selectors cannot be used to manipulate another component within the same component.

9. After repeated uninstallation and remounting, the animation cannot be overlaid, and the console should not display an error message about accessing a deleted node.

10. When the system has prefers-reduced-motion enabled, the final layout will be displayed directly.

11. The page needs to have a clear empty state, and no blank or broken areas should be left after the component is uninstalled.

Create App.vue, MotionGallery.vue, main.js, style files, package.json, and README.md.

After completion, execute `npm install` and `npm run build`. Once the build is successful, start the development server and return a locally accessible address.

The Vue lifecycle, GSAP scope, and uninstallation cleanup have been presented as an interactive front-end demo, demonstrating a high level of completion. The visual presentation is also quite good. The two sets of posters have a clear contrast between warm and cool tones.

AI Programming is moving from adding a few lines of code to directly delivering a working page.

Anthropic analyzed 500,000 programming-related interactions.Claude 79% of the dialogue in Code belongs to AI Direct task execution mode; JavaScript and HTML are the most common languages, and UI/UX component development is also a major application.

Gsap-skills Organize GreenSock's engineering experience into Agent The rules can be read directly. The differences are already evident in 8 test cases: Timeline no longer relies on a series of delays, scroll animations know where to place the ScrollTrigger, and React and Vue components will actively clean up Tween when unloading.

Gsap-skills Suitable for creating product demos, release pages, and portfolios; it can unify animation style and reduce quality fluctuations between different pages.

AI As page generation becomes faster, engineering rules that allow generated code to be successfully integrated into real projects will become increasingly valuable. GSAP Skills fills this gap with animation.
