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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00067 | $0.01260 |
| Opus 5 | $0.00034 | $0.00630 |
| Sonnet 5 | $0.00013 | $0.00252 |
| Haiku 4.5 | $0.00007 | $0.00126 |
Grade A, and why
metaverse-expert 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.

Metaverse Expert
Create production-ready metaverse experiences including VR/AR applications, virtual worlds, social platforms, and blockchain-integrated digital assets.
Learning Objectives
- Master VR/AR development for immersive experiences
- Build virtual worlds using Unity and Unreal Engine
- Implement spatial computing and 3D interactions
- Integrate blockchain and NFTs in metaverse applications
- Optimize performance for real-time 3D rendering
Prerequisites
- Strong C# or C++ programming skills
- Understanding of 3D mathematics and graphics
- Knowledge of game development principles
- Familiarity with XR hardware and SDKs
Core Concepts
Extended Reality (XR)
Umbrella term encompassing Virtual Reality (VR), Augmented Reality (AR), and Mixed Reality (MR). VR provides fully immersive digital environments, AR overlays digital content on the real world, and MR blends both seamlessly.
Spatial Computing
Technology enabling digital content to interact with three-dimensional space. Includes position tracking, gesture recognition, spatial mapping, and environmental understanding for natural human-computer interaction.
Virtual Worlds
Persistent, shared 3D environments where users interact through avatars. Features include real-time multiplayer networking, user-generated content, virtual economies, and social interactions.
Digital Assets & NFTs
Unique digital items represented as blockchain tokens (NFTs). Includes virtual land, wearables, art, and in-game items with verifiable ownership and cross-platform interoperability.
Metaverse Platforms
Interconnected virtual ecosystems like Decentraland, The Sandbox, Roblox, and VRChat. Each provides tools for creation, social interaction, commerce, and experiences within their virtual worlds.
Best Practices
VR/AR Development
- Maintain consistent 90+ FPS for VR to prevent motion sickness
- Implement comfort options (teleportation, snap turning, vignette)
- Use appropriate UI scale and placement (1-3 meters from user)
- Provide clear visual and haptic feedback for interactions
- Test on target hardware extensively
- Implement locomotion options for different user preferences
- Follow platform-specific guidelines (Oculus, SteamVR, ARKit)
What ships with it
1 file 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.

metaverse-expert is a skill published in the GitHub repository personamanagmentlayer/pcl (40 stars, last pushed 2d ago), licensed Apache-2.0. It adds 67 tokens to every session and 1,260 once invoked, about $0.0003 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 2026-09-05.
