3d

3d is a command for Claude Code from mrgoonie/human-mcp. It costs 10 tokens per session (664 once invoked), scanned A, original, MIT.

A command for building interactive 3D web experiences with Three.js, a JavaScript library for displaying 3D graphics in a browser. It covers scenes with particles, shaders, camera controls, lighting effects, and responsive layouts.

In plain words
What is it for?
Use it to create browser-based 3D scenes, such as immersive visualizations or interactive product experiences. It supports planning, GPU-based particles, custom visual effects, camera movement, and optimization.
Why use it?
It provides a defined workflow for planning, implementing, and reviewing a 3D design. It also calls for attention to browser performance across different devices.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

3d 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 5d 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.

Think hard to plan & start working on these tasks follow the Orchestration Protocol, Core Responsibilities, Subagents Team and Development Rules: $ARGUMENTS

Workflow:

  1. Use ui-ux-designer subagent and researcher subagent to create a comprehensive 3D design plan with TODO tasks in ./plans directory.
  2. Then use ui-ux-designer subagent to implement the plan step by step.
  3. Create immersive 3D experiences using Three.js with particle effects, custom shaders, and interactive elements.
  4. Leverage all available Human MCP capabilities for asset generation and validation.
  5. Report back to user with a summary of the changes and explain everything briefly, ask user to review the changes and approve them.
  6. If user approves the changes, update the ./docs/design-guideline.md docs if needed.

3D Design Requirements:

  • Implement Three.js scenes with proper optimization
  • Create custom GLSL shaders for unique visual effects
  • Design GPU-accelerated particle systems
  • Add immersive camera controls and cinematic effects
  • Implement post-processing effects and render pipelines
  • Ensure responsive behavior across all devices
  • Optimize performance for real-time rendering
  • Add interactive elements and smooth animations

Human MCP Tools Integration:

Hands Tools (Image/Video Generation):

  • Generate textures, skyboxes, and environment maps with Gemini API
  • Create custom particle sprites and effect assets
  • Generate 3D object textures with specific styles
  • Create video backgrounds for immersive scenes
  • Apply camera movements for dynamic visual effects
  • Use inpainting/outpainting for seamless texture creation

JIMP Tools (Image Processing):

  • Process and optimize textures for WebGL
  • Create normal maps and height maps from images
  • Generate sprite sheets for particle systems
  • Remove backgrounds for transparent textures
  • Resize and optimize assets for performance
  • Apply masks for complex texture effects

Eyes Tools (Visual Analysis):

  • Analyze reference images for 3D scene composition
  • Compare design mockups with implementation
  • Validate texture quality and visual consistency
  • Extract color palettes from reference materials
  • Verify shader effects and visual output

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.

3d is a command published in the GitHub repository mrgoonie/human-mcp (294 stars, last pushed 5mo ago), licensed MIT. It adds 10 tokens to every session and 664 once invoked, about $0.0001 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 2026-08-30.
