embodiedgen

embodiedgen is a skill for Claude Code, Codex from nebius/nebius-physical-ai. It costs 42 tokens per session (1,294 once invoked), scanned A, original, Apache-2.0.

A workflow skill for turning an image of a rigid object into a URDF model, collision meshes, and a physics check in PyBullet. URDF is a standard robot description format; PyBullet is a physics simulator.

In plain words
What is it for?
Use it for the specified private EmbodiedGen V2 workflow: image-to-object generation, URDF export, collision validation, and PyBullet simulation.
Why use it?
It checks whether the generated object can make contact with the ground, settle under gravity, and produce valid video evidence instead of stopping at model generation.

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

embodiedgen 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 10d 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 — 96 lines — stays where its author put it; the contents beside it link to each section on GitHub.

EmbodiedGen V2 image-to-rigid-object

Use this skill only for the scoped, Tier-1 EmbodiedGen V2 workflow. The stable user surface is workflows/testing/byof-embodiedgen.yaml through generic npa workbench workflow commands—not a persistent service, separate SDK submitter, or an embodiedgen command family. Start with the operator guide, then use the workflow catalog and OSS capability record.

Capability boundary

The qualified private capability is img3d-cli_trellis_image_to_urdf_pybullet. The real upstream TRELLIS backend runs through EmbodiedGen img3d-cli, emits a URDF and collision meshes, converts that URDF to MJCF, and validates the exact generated URDF in PyBullet for gravity contact, settling, and a fully decoded MP4. TRELLIS is selected; SAM3D and the Tencent cloud backend are not substitutes.

Generated mass, height, and friction are VLM estimates—not calibrated ground truth. Do not claim articulated-object generation, physics validation in MuJoCo/Genesis, downstream policy improvement, or model quality. MJCF is a supported handoff only; PyBullet is the simulator actually exercised.

Before submission

  1. Resolve the project, private registry, storage, and Kubernetes context from supported NPA configuration. A host name is not a project alias.
  2. Run npa workbench health preflight --checks nebius,token_factory,s3 --json with the selected project, then npa workbench health access --capability token_factory --json. TRELLIS is public: do not invent an acceptance flag.
  3. Obtain an operator-private, immutable REGISTRY/npa-embodiedgen@sha256:<64-hex> image. The tag before resolution must be dev-<full-40-character-NPA-sha> when an operator builds a new image. Consumers use the already-qualified digest from supported configured private delivery; never publish or use a public registry image.
  4. Pass NEBIUS_TOKEN_FACTORY_KEY only with --secret-env; it is needed by upstream property estimation and must never be written to YAML, reports, or shell logs.
  5. Use a worker-readable https:// or s3:// image URI, never a local path. The workflow base64-transports it through the rendered shell as literal data; reachability and storage permission remain separate prerequisites.

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.

embodiedgen is a skill published in the GitHub repository nebius/nebius-physical-ai (50 stars, last pushed today), licensed Apache-2.0. It adds 42 tokens to every session and 1,294 once invoked, about $0.0002 per session on Opus 5.5. 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 2026-10-12.
