room-creator

room-creator is a skill for Claude Code, Codex from HorizonRobotics/EmbodiedGen. It costs 75 tokens per session (872 once invoked), scanned A, original, Apache-2.0.

A tool for generating indoor rooms or whole houses as 3D scenes, with optional URDF and USD exports. URDF and USD are file formats used to describe scenes and objects for robotics and 3D software.

In plain words
What is it for?
Creating rooms, choosing room type and complexity, using a natural-language scene prompt, controlling the random seed, and generating or exporting URDF and USD files.
Why use it?
It turns a room description and settings such as type, complexity, and seed into a reproducible generated scene. It can also export an existing generated scene into the supported formats.

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

room-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 8d 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 — 85 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Room Creator

Generate room scenes with room-cli -m embodied_gen.scripts.room_gen.gen_room from infinigen(https://github.com/princeton-vl/infinigen) and optionally export URDF/USD. room-cli forwards its arguments to the bundled Blender Python (has bpy and room deps installed by bash install.sh room); running python -m embodied_gen.scripts.room_gen.gen_room from the embodiedgen env works too since heavy stages dispatch to Blender Python internally either way.

Use This Workflow

  1. Confirm output root and target room profile.
  2. Choose generation scope:
  • --gen --urdf --usd for full pipeline.
  • --gen --no-urdf --no-usd for generation only.
  • --no-gen --urdf --usd for export from existing blender output.
  1. Run the command from repository root.
  2. Verify output folder: <output_root>/<RoomType>_seed<seed>/ (if --seed is omitted, check the generated seed from logs first).

Parameters

  • --output-root (required): base output directory.
  • --prompt: natural-language task/scene description; a GPT router infers room type and complexity from it, overriding --room-type/--complexity. Requires a configured GPT agent.
  • --room-type: Bedroom | LivingRoom | Kitchen | Bathroom | DiningRoom | Office | House.
  • --seed: random seed. For reproducible runs, pass this explicitly; if omitted, a random seed is generated.
  • --complexity: minimalist | simple | medium | detail.
  • --custom-params: gin file copied to Infinigen custom_solve.gin.
  • --large-scene: only for House; enables more rooms.
  • --gen/--no-gen, --urdf/--no-urdf, --usd/--no-usd: pipeline switches.

Complexity Guidance

  • minimalist: fastest, sparse furniture.
  • simple: default, balanced quality/time.
  • medium: richer layout, slower.
  • detail: highest detail, longest runtime.

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.

room-creator is a skill published in the GitHub repository HorizonRobotics/EmbodiedGen (659 stars, last pushed 15d ago), licensed Apache-2.0. It adds 75 tokens to every session and 872 once invoked, about $0.0004 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.
