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 | $0.00145 | $0.01465 |
| Opus 5 | $0.00072 | $0.00732 |
| Sonnet 5 | $0.00029 | $0.00293 |
| Haiku 4.5 | $0.00015 | $0.00146 |
Grade A, and why
scenario-3d-worlds 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 12d 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.
How it starts
The opening of the file, as written. The whole thing — 58 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Scenario 3D Worlds
Overview
These models build explorable environments as 3D Gaussian splats, not polygon meshes: volumetric scenes to walk through and render in real time, with no UVs or topology to edit (Marble splats also export to triangle or collider mesh). Three vendors sit side by side: World Labs Marble in three quality tiers, Hunyuan's HY World pipeline, and TripoSplat for single objects. Discover them with search and treat model_schema_get as the contract; HY World members carried a geo restriction tag at authoring time, so hits differ by team and region.
Connection and the core loop: see the scenario skill; polygon meshes, rigging, and the 3D viewer: the scenario-3d skill; skybox-only work with no splat stage: the scenario-skyboxes skill. If a sibling skill named here is missing from your available skills, ask the user to install it (npx skills add scenario-labs/skills --skill <name>); unattended, proceed from tool schemas and flag the gap.
Quick reference
Pick the member by what you already have (input names from the live schemas):
| You have | Member | Inputs |
|---|---|---|
| A text idea | Marble, any tier | prompt alone |
| One image, flat or 360 | Marble | images, one entry; isPano: true if 360 |
| 2 to 8 photos of one scene | Marble | images |
| A walkthrough video | Marble or HY Multi-view to Splat | video |
| Many overlapping photos | HY Multi-view to Splat | images, 2 to 64 at authoring time |
| One photo of a place | HY Image to Skybox, then Skybox to Splat | image, then panorama |
| One photo of an object | TripoSplat | image; background removal is automatic |
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.

scenario-3d-worlds is a skill published in the GitHub repository scenario-labs/skills (11 stars, last pushed today), licensed MIT. It adds 145 tokens to every session and 1,465 once invoked, about $0.0007 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 2026-08-31.
