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 |

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
