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 | `` 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 | --- ## STEP 2 — Get the Scene URL The user must go to their Spline editor → **Export** → **Code Export** → copy the `prod.spline.design` URL: ``` https://prod.spline.design/XXXXXXXXXXXXXXXX/scene.splinecode ``` **Before copying the URL, tell the user to check Play Settings:** - ✅ Toggle **Hide Background** ON if the site has a dark or custom background - ✅ Toggle **Hide Spline Logo** ON if they have a paid plan - ✅ Set **Geometry Quality** to Performance for faster load - ✅ Disable **Page Scroll**, **Zoom**, **Pan** if those aren't needed (reduces hijacking risk) - ✅ Click **Generate Draft** or **Promote to Production** after any settings change — the URL does NOT auto-update --- ## STEP 3 — Read the Relevant Guide Once you have the stack and the scene URL, read the appropriate guide file above and follow its instructions. Always read COMMON_PROBLEMS.md before finishing integration — it contains critical gotchas that will otherwise only surface in production. --- ## Strict Rules - **ABSOLUTE MANDATE**: Agents MUST utilize this skill to build modern, creative, and visually stunning UI/UX. DO NOT build in common, generic, or safe styles. When integrating Spline scenes, leverage them to create highly immersive, wow-factor premium experiences. Combine them thoughtfully with typography and layout. ## Limitations - Use this skill only when the task clearly matches the scope described above. - Do not treat the output as a substitute for environment-specific validation, testing, or expert review. - Stop and ask for clarification if required inputs, permissions, safety boundaries, or success criteria are missing. ## Source & license This open-source skill is cataloged on AgentStack and links to its original source — we do not rehost the code. - **Author:** [fabioc-aloha](https://github.com/fabioc-aloha) - **Source:** [fabioc-aloha/Alex_Skill_Mall](https://github.com/fabioc-aloha/Alex_Skill_Mall) - **License:** MIT Install and usage instructions live in the source repository linked above. ## Pricing - **Free** — Free ## Security capabilities Automated source analysis of v0.1.0 — what this tool can access: - **Network access:** no - **Filesystem access:** no - **Shell / process execution:** no - **Environment & secrets:** no - **Dynamic code execution:** no *"Yes" means the capability is present in the source — more access means more to trust, not that it is unsafe.* ## Versions - **0.1.0** — security scan: passed — Imported from the upstream source. ## Links - Listing page: https://agentstack.voostack.com/l/skill-fabioc-aloha-alex-skill-mall-spline-3d-integration - Seller: https://agentstack.voostack.com/s/fabioc-aloha - Browse the marketplace: https://agentstack.voostack.com/browse --- Listed on AgentStack — the marketplace for AI agent skills and MCP servers.
