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 | $0.00000 | $0.04110 |
| Opus 5.5 | $0.00000 | $0.01644 |
| Sonnet 5.5 | $0.00000 | $0.00822 |
| Haiku 4.5 | $0.00000 | $0.00411 |
Grade A, and why
3d_scene 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 1mo 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 — 309 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Generate 3D Scene — Strategy Skill
Choose how to build a 3d_scene asset. Do not default to one pipeline for every
task: what the user specified about the scene's appearance matters more than the
scene type, and generative reconstruction is the least stable route here.
Decision
Ask first: did the user specify the scene's 3D appearance?
| Situation | Prefer | Why |
|---|---|---|
| Appearance not specified — no reference image, no described look | Downloadable, licence-checked assets. Search the selected engine's own asset library for a usable scene or environment kit: UE5 (Fab / Marketplace, Quixel), Unity (Asset Store, packages), Godot (Asset Library), Blender (bundled assets, CC0 libraries), three.js (curated CC0 packs — see <REPO_PATH>/agent_skills/engine_context/three_js_api.md) |
Nothing constrains the look, so a licensed, artist-made scene is more shippable than anything generated, and it imports through a documented path. Record source and licence |
| Appearance specified — reference image or a described look | Lay out the terrain/ground first, then add foreground objects (see Ground first, then objects below, and Scene construction code chain for the mechanised form) | WorldPlay-style reconstruction is not yet stable enough to be the default. Ground + placed props is controllable, editable, and reproduces a requested look reliably |
| Appearance specified, the space is indoor/enclosed, and the user needs high fidelity | WorldPlay-style reconstruction | This is the one case where the reconstruction path earns its instability: an enclosed volume has no horizon or sky to break, and one reference image can carry the whole interior |
Prefer downloadable assets even when the appearance is specified, if a library scene already matches the requested look — generation is not a goal in itself.
Do not silently switch strategies. State which row you selected and why, and if the user asked for the reconstruction path outside the indoor high-fidelity case, say that it is the unstable route before spending time on it.
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_scene is a skill published in the GitHub repository OpenDCAI/GameFactory-3A (956 stars, last pushed yesterday), licensed Apache-2.0. It costs nothing until one of its globs matches a file; then it loads 4,110 tokens. 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.
