layout-creator

layout-creator is a skill for Claude Code, Codex from HorizonRobotics/EmbodiedGen. It costs 62 tokens per session (819 once invoked), scanned A, original, Apache-2.0.

A skill for generating interactive 3D scenes from task descriptions, such as putting a pen in a mug, using EmbodiedGen's layout-cli. It can create simulator-ready layout files and renders from background scenes.

In plain words
What is it for?
Use it to create one or many task-based layouts, add a robot when needed, and prepare scenes for simulation.
Why use it?
It turns written tasks into scene layouts without requiring you to build each arrangement by hand. Retry and seed settings help control generation results and repeatability.

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

layout-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 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.

Layout Creator

Unified entry for EmbodiedGen interactive layout generation via layout-cli.

When To Use

Use this skill when users want to:

  • Generate interactive 3D scenes from task descriptions.
  • Batch-generate layouts from a task list file.
  • Build simulator-ready layout outputs (layout.json, renders) with optional robot insertion.
  • Tune generation quality and stability via retry and seed settings.

Routing Rule (Core)

Use layout-cli when the user input is task-level natural language descriptions (e.g., "put the pen in the mug") and the target output is an interactive layout scene, not standalone assets or standalone background scenes.

Pre-checks

  1. Run commands from the repository root.
  2. Confirm the active environment is embodiedgen.
  3. Confirm background scene list file exists and is readable (via --bg_list).
  4. If CLI commands are unavailable, run pip install -e . to register entrypoints.

Standard Command Templates

1) Generate layouts from inline task descriptions

layout-cli \
  --task_descs "Place the pen in the mug on the desk" "Put the fruit on the table on the plate" \
  --bg_list "outputs/example_gen_scenes/scene_part_list.txt" \
  --output_root "outputs/layouts_gen" \
  --insert_robot

2) Batch generation from task list file (background run)

layout-cli \
  --task_descs "apps/assets/example_layout/task_list.txt" \
  --bg_list "outputs/example_gen_scenes/scene_part_list.txt" \
  --n_image_retry 4 --n_asset_retry 3 --n_pipe_retry 3 \
  --output_root "outputs/layouts_gens" \
  --insert_robot > layouts_gens.log 2>&1 &

Common Parameters

  • --task_descs: task descriptions or a task-list text file path.
  • --output_root: root output directory.
  • --bg_list: background scene list file (scene retrieval pool).
  • --insert_robot: include robot pose in layout generation/simulation output.
  • --output_iscene: export composed scene mesh (Iscene.glb).
  • --n_image_retry --n_asset_retry --n_pipe_retry: retry controls for text-to-3D subpipeline.
  • --seed_img --seed_3d --seed_layout: reproducibility controls.
  • --n_img_sample --text_guidance_scale --img_denoise_step: text-to-image / asset-generation controls.
  • --keep_intermediate: keep intermediate files from generation substeps.
