What it does

Spline 3D Integration is an agent skill from sickn33/agentic-awesome-skills. Use when adding interactive 3D scenes from Spline.design to web projects, including React embedding and runtime control API.

Its SKILL.md is about 1.2k tokens, which your agent loads only when the skill is triggered. The skill folder holds 9 other files (for example `guides/COMMON_PROBLEMS.md`, `guides/PERFORMANCE.md` and `guides/REACT_INTEGRATION.md`).

It sits in AI & LLM Engineering, covering Embeddings and 3D graphics and WebGL. It works with React. The repository describes itself as: AAS Core is the local, agent-first control plane for complete catalog discovery, agent-owned selection, stack validation, and planning, backed by 2,400+ agentic skills. Includes… The licence is MIT.

When your agent uses it

  • Adding interactive 3D scenes from Spline.design to web projects
  • Including React embedding and runtime control API

Example prompts

  • “/spline-3d-integration”

Workflow steps

3 steps, taken from the step headings in SKILL.md.

  1. Identify the Stack
  2. Get the Scene URL
  3. Read the Relevant Guide

What it can do on your machine

Read from SKILL.md and the folder at commit 680176d. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Hosts in commands or code, which the agent is likely to contact:

    • prod.spline.design

    Also links to:

    • spline.design

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Spline 3D Integration loads about 1.2k tokens when it runs. Until then it costs about 37 tokens; SKILL.md has 419 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~37
When it runs · the whole SKILL.md, loaded when a task matches
~1.2k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

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

TaskGuide
Vanilla HTML/JS embedguides/VANILLA_INTEGRATION.md
React / Next.js / Vue embedguides/REACT_INTEGRATION.md
Performance & mobile optimizationguides/PERFORMANCE.md

Working Examples

examples/interactive-scene.tsxFull 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.

StackMethod
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

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

Show full SKILL.md (133 more words)Show less

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.
