GSAP Router

Routes to 4 specialized skills based on animation requirements.

Routing Protocol

Classify — Identify animation type from user request
Match — Apply signal matching rules below
Combine — Production animations often need 2-3 skills together
Load — Read matched SKILL.md files before implementation

Quick Route

Tier 1: Core (Start Here)

Need	Skill	Signals
Basic animations, easing	`gsap-fundamentals`	tween, animate, ease, from, to, duration, delay
Complex sequences	`gsap-sequencing`	timeline, sequence, orchestrate, labels, callbacks
Scroll animations	`gsap-scrolltrigger`	scroll, pin, scrub, parallax, reveal, sticky
React integration	`gsap-react`	React, useGSAP, ref, hook, cleanup, context

Signal Matching

Primary Signals

gsap-fundamentals:

"animate", "tween", "transition"
"ease", "easing", "timing"
"from", "to", "fromTo"
"duration", "delay", "repeat"
"stagger", "properties"

gsap-sequencing:

"timeline", "sequence", "orchestrate"
"labels", "callbacks", "nested"
"position parameter", "overlap"
"complex animation", "choreography"
"play", "pause", "reverse", "seek"

gsap-scrolltrigger:

"scroll", "ScrollTrigger"
"pin", "sticky", "fixed"
"scrub", "parallax"
"reveal on scroll", "snap"
"progress indicator"

gsap-react:

"React", "component"
"useGSAP", "useRef", "hook"
"cleanup", "context"
"event handler", "state"

Confidence Scoring

High (3+ signals) — Route directly to matched skill
Medium (1-2 signals) — Route with fundamentals as foundation
Low (0 signals) — Start with
```
gsap-fundamentals
```

Common Combinations

Basic Animation (1 skill)

gsap-fundamentals → Tweens, easing, basic properties

React Component Animation (2 skills)

gsap-fundamentals → Animation principles, easing
gsap-react → Hook patterns, cleanup, refs

Scroll-Based Experience (3 skills)

gsap-scrolltrigger → Scroll triggers, pinning
gsap-sequencing → Timeline for pinned sections
gsap-fundamentals → Individual animations

Full Production (3-4 skills)

gsap-fundamentals → Core animations
gsap-sequencing → Complex orchestration
gsap-react → Framework integration
gsap-scrolltrigger → Scroll interactions (if needed)

Decision Table

Framework	Animation Type	Complexity	Route To
Vanilla JS	Simple	Low	fundamentals
Vanilla JS	Sequenced	Medium	fundamentals + sequencing
Vanilla JS	Scroll-based	Medium	fundamentals + scrolltrigger
React	Simple	Low	fundamentals + react
React	Complex	High	All four skills
React	Scroll	Medium	react + scrolltrigger

Animation Categories

Animation Type	Primary Skill	Supporting Skill
Fade in/out	`gsap-fundamentals`	-
Slide/move	`gsap-fundamentals`	-
Scale/rotate	`gsap-fundamentals`	-
Stagger	`gsap-fundamentals`	-
Page transitions	`gsap-sequencing`	fundamentals
Orchestrated reveals	`gsap-sequencing`	fundamentals
Scroll reveals	`gsap-scrolltrigger`	fundamentals
Parallax	`gsap-scrolltrigger`	-
Pinned sections	`gsap-scrolltrigger`	sequencing
React animations	`gsap-react`	fundamentals
React + scroll	`gsap-react`	scrolltrigger

Integration with Other Domains

With R3F (r3f-*)

r3f-fundamentals → 3D scene setup
gsap-fundamentals → Object property animation
gsap-sequencing → Camera movements, scene transitions

GSAP animates Three.js object properties via

onUpdate

With Post-Processing (postfx-*)

postfx-composer → Effect setup
gsap-fundamentals → Animate effect parameters
gsap-sequencing → Transition between effect states

GSAP drives effect intensity, colors, etc.

With Audio (audio-*)

audio-playback → Music timing
gsap-sequencing → Sync animations to audio cues
gsap-fundamentals → Audio-reactive property changes

Timeline callbacks sync with audio events.

With Particles (particles-*)

particles-systems → Particle emitters
gsap-fundamentals → Animate emitter properties
gsap-sequencing → Particle burst sequences

Workflow Patterns

Page Load Animation

1. gsap-fundamentals → Understand tweens, easing
2. gsap-sequencing → Build entrance timeline
3. gsap-react → Integrate with React (if applicable)

Scroll Experience

1. gsap-scrolltrigger → Set up triggers, pins
2. gsap-sequencing → Build scrubbed timelines
3. gsap-fundamentals → Individual animation properties

Interactive UI

1. gsap-fundamentals → Hover, click animations
2. gsap-react → Event handlers, cleanup
3. gsap-sequencing → Complex interaction sequences

Temporal Collapse Stack

For the New Year countdown project:

gsap-fundamentals → Digit animations, pulse effects, easing
gsap-sequencing → Countdown sequence, final moment orchestration
gsap-react → Component integration, cleanup

Key animations:

Digit flip on time change
Pulse/glow intensity over time
Final countdown dramatic sequence
Celebration reveal at zero

Fallback Behavior

No framework stated → Assume vanilla JS, start with
```
gsap-fundamentals
```
React mentioned → Add
```
gsap-react
```
to combination
Scroll mentioned → Add
```
gsap-scrolltrigger

Performance Priority

When performance is critical:

```
gsap-fundamentals
```
— Use transforms, avoid layout properties
```
gsap-react
```
— Proper cleanup prevents memory leaks
```
gsap-scrolltrigger
```
— Use
```
scrub
```
wisely, batch updates
```
gsap-sequencing
```
— Reuse timelines, don't recreate
