Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00024 | $0.00968 |
| Opus 5 | $0.00012 | $0.00484 |
| Sonnet 5 | $0.00005 | $0.00194 |
| Haiku 4.5 | $0.00002 | $0.00097 |
Grade A, and why
spline-3d-integration 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 yesterday.
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
88% identical to spline-3d-integration — 21 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 3D Integration Skill
Master guide for embedding interactive 3D scenes from Spline.design into web projects.
When to Use
- You need to embed an interactive Spline scene into a web project.
- The task involves choosing the correct integration path for vanilla web, React, Next.js, Vue, or iframe contexts.
- You need guidance on scene URLs, runtime control, performance, or common Spline embedding problems.
Quick Reference
| Task | Guide |
|---|---|
| Vanilla HTML/JS embed | guides/VANILLA_INTEGRATION.md |
| React / Next.js / Vue embed | guides/REACT_INTEGRATION.md |
| Performance & mobile optimization | guides/PERFORMANCE.md |
| Debugging & common problems | guides/COMMON_PROBLEMS.md |
Working Examples
| File | What it shows |
|---|---|
| examples/vanilla-embed.html | Minimal vanilla JS embed with background + fallback |
| examples/react-spline-wrapper.tsx | Production-ready lazy-loaded React wrapper with fallback |
| examples/interactive-scene.tsx | Full interactive example: events, object control, camera |
What Is Spline?
Spline is a browser-based 3D design tool — think Figma, but for 3D. Designers create interactive 3D scenes (objects, materials, animations, physics, events) in the Spline editor, then export them for the web via a hosted .splinecode file URL.
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-3d-integration is a skill published in the GitHub repository beel-collab/presets.dev (2 stars, last pushed 4mo ago), licensed MIT. It adds 24 tokens to every session and 968 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. It is 88% identical to spline-3d-integration, differing in 21 lines, and is treated as a copy.
