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 5.1 | $0.00032 | $0.00831 |
| Opus 5 | $0.00016 | $0.00415 |
| Sonnet 5 | $0.00006 | $0.00166 |
| Haiku 4.5 | $0.00003 | $0.00083 |
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 8d 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.

Spline 3D Integration Skill
Master guide for embedding interactive 3D scenes from Spline.design into web projects.
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.
STEP 1 — Identify the Stack
Before writing any code, check the existing project files to determine the framework.
| Stack | Method |
|---|---|
| Vanilla HTML/JS | <spline-viewer> web component OR @splinetool/runtime |
| React / Vite | @splinetool/react-spline |
| Next.js | @splinetool/react-spline/next |
| Vue | @splinetool/vue-spline |
| iframe (Webflow, Notion, etc.) | Public URL iframe |
What ships with it
7 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.
- 8d ago First seen · 81 lines · 32 tokens per session scan A 4b9c679d100b
spline-3d-integration is a skill published in the GitHub repository ratnesh-maurya/cursor-claude-personas (8 stars, last pushed 5mo ago), licensed MIT. It adds 32 tokens to every session and 831 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
