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 | $0.00065 | $0.00601 |
| Opus 5 | $0.00032 | $0.00300 |
| Sonnet 5 | $0.00013 | $0.00120 |
| Haiku 4.5 | $0.00006 | $0.00060 |
Grade A, and why
background-creator 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 6d 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.

Background Creator
Unified entry for EmbodiedGen background scene generation via scene3d-cli.
When To Use
Use this skill when users want to:
- Generate indoor/background 3D scenes from text prompts.
- Pre-generate scene assets for
layout-cli. - Control
scene3d-cliruntime/quality via seed, retry, andgs3dsettings.
Routing Rule (Core)
Use scene3d-cli when input is scene-level text prompts and output target is a background scene (mesh + 3DGS), not single foreground assets.
Pre-checks
- Run commands from the repository root.
- Confirm the active environment is
embodiedgen. - Install scene3d dependencies first if needed:
bash install.sh scene3d - If CLI commands are unavailable, run
pip install -e .to register entrypoints.
Standard Command Template
scene3d-cli --prompts "Art studio with easel and canvas" \
--output_dir outputs/bg_scenes \
--seed 0 \
--gs3d.max_steps 4000 \
--disable_pano_check
Common Parameters
--prompts: one or more scene text prompts.--output_dir: output root directory for generated scenes.--seed: random seed for reproducibility.--n_retry: panorama generation retries.--real_height: force target real-world room height in meters.--pano_image_only: generate only panorama image (debug/fast validation).--disable_pano_check: skip panorama quality check.--keep_middle_result: keep intermediate training artifacts.--gs3d.max_steps: training steps for 3DGS optimization.
Output Conventions
Each prompt is saved under <output_dir>/scene_xxxx/, typically including:
gs_model.plymesh_model.plypano_image.pngprompt.txtvideo.mp4gsplat_cfg.yml
Runtime Expectations
- Typical full generation time is around 30 minutes per scene.
- Use
--pano_image_onlyfor quick prompt validation before full generation.
Failure Handling and Retry
- OOM or GPU pressure: reduce concurrency and lower
--gs3d.max_steps. - Unstable scene quality: increase
--n_retryor adjust prompt specificity. - Missing outputs: verify
--output_dirpermissions and use absolute paths.
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.

background-creator is a skill published in the GitHub repository HorizonRobotics/EmbodiedGen (655 stars, last pushed 12d ago), licensed Apache-2.0. It adds 65 tokens to every session and 601 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 2026-08-30.
Other skills, from other repositories
gameobject-component-destroy
Destroy one or more Components from a target GameObject. Missing (null) components are skipped — they cannot be destroyed. Use 'gameobject-find' and 'gameobject-component-get' to identify the components first.
unity-version-split
Split a C# file into Unity 6.5+ and pre-Unity 6.5 variants. Use when a file needs different implementations for different Unity versions due to API changes (e.g., EntityId vs int, GetEntityId vs GetInstanceID).
playtest-report
Generates a structured playtest report template or analyzes existing playtest notes into a structured format. Use this to standardize playtest feedback collection and analysis.
unity-manual-component
Manually add, configure, reorder, and copy components on GameObjects using Unity Editor UI. For one-off Inspector workflows that do not need REST automation.
godot-signals-groups
Build event-driven, decoupled Godot 4.7 gameplay with signals and node groups: declare and emit custom signals, connect with Callables (incl. bind/one-shot), and broadcast to many nodes via groups and callgroup. Use when wiring node communication in a Godot project, replacing tight references with signals…
threejs-exposure-color-grading
Build a measured exposure and grading path in Three.js. Use for a 64x36 encoded luminance meter, asynchronous readback, weighted log-average exposure, asymmetric adaptation, single tone-map ownership, and a generated 32-cube post-tone-map LUT.
