Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00111 | $0.04952 |
| Opus 5 | $0.00056 | $0.02476 |
| Sonnet 5 | $0.00022 | $0.00990 |
| Haiku 4.5 | $0.00011 | $0.00495 |
Grade A, and why
spline-interactive scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 7d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
This is a copy
100% identical to spline-interactive — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

Spline Interactive - Browser-Based 3D Design and Animation
Overview
Spline is a browser-based 3D design and animation platform that enables creators to build interactive 3D experiences without requiring code or specialized software knowledge. It provides a collaborative visual editor for designing, animating, and exporting 3D scenes across multiple platforms.
Key Features:
- Visual 3D modeling with parametric shapes, extrusion, and boolean operations
- State-based animation system with timeline controls
- Interactive event system (mouse, keyboard, collision, scroll)
- Multiple export options (React components, web code, public URLs)
- Real-time collaboration with team libraries
- AI-powered generation (3D from text, textures, style transfer)
- Built-in physics and particle systems
When to Use This Skill:
- Creating 3D web experiences without writing Three.js code
- Designing interactive product showcases or configurators
- Prototyping 3D UI/UX concepts visually
- Building marketing pages with 3D elements
- Collaborating with designers on 3D content
- Exporting scenes for React or vanilla JS integration
Alternatives:
- Three.js (threejs-webgl): For developers who prefer code-first approach and need maximum control
- Babylon.js (babylonjs-engine): For game-focused projects with built-in physics
- React Three Fiber (react-three-fiber): For React developers who want to build 3D with JSX
Core Concepts
1. Scene Structure
Spline organizes projects into scenes containing:
- Objects: 3D models, shapes, text, images
- Lights: Directional, point, spot lights
- Cameras: Orbital, perspective, orthographic
- Events: Interaction triggers
- States: Animation keyframes
2. Components System
Reusable elements that can be:
- Created from any object or group
- Instantiated multiple times
- Updated across all instances
- Overridden per instance
3. State-Based Animation
Animations are defined as transitions between states:
- Default State: Initial appearance
- Additional States: Target appearances
- Events: Triggers that cause state transitions
- Transitions: Duration, easing, properties
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

spline-interactive is a skill published in the GitHub repository Kevin-Liu-01/Agent-Machines (27 stars, last pushed today), licensed MIT. It adds 111 tokens to every session and 4,952 once invoked, about $0.0006 per session on Opus 5. A static security scan graded it A with 0 findings. It is 100% identical to spline-interactive, differing in 0 lines, and is treated as a copy.
