marble SKILL.md skillA
marble from nebius/nebius-physical-ai is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add nebius/nebius-physical-ai/marble@git:20261010.bc67155Pins git:20261010.bc67155 in mdr.lock. Pin the fingerprint instead.

Generate or import World Labs Marble worlds into NPA and run native CUDA capture or spatial-scan workflows with factual interactive HTML reports.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Marble For generated-site Go1 inspection, use one workflow: `workflows/testing/marble-go1-inspection.yaml` with exactly one native `--preset warehouse|shipyard|home|factory|utility` selection. Omission defaults to warehouse. Each submission runs one hosted generation using `WLT_API_KEY`, one RTX PRO 6000 collection and one continuous 25 FPS standalone HTML report. It never fans out across situations. The guide is `docs/workbench/guides/marble-robot-presets.md`; for a custom world, omit `--preset` and override `world_prompt` and `workflow_preset` on the same YAML. Use the native `write_quadruped_gallery` to combine completed reports into an offline situation selector retaining every original video and trajectory row. All five parameterizations have prior native GPU evidence from the retired combined workflow; distinguish that evidence from new-entrypoint submissions. These are Go1 presets, not ANYmal or Spot. Do not advertise thermal inspection, defect detection, household manipulation or new RL training. For detailed quadruped collection, use `workflows/testing/marble-warehouse-quadruped.yaml` and …

How to install
mdr add nebius/nebius-physical-ai/marble@sha256:b29c881f6b560befThe line at the top of this page pins the label git:20261010.bc67155, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
