ray-workbench SKILL.md skillA
ray-workbench 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/ray-workbench@git:20260909.3f06aa7Pins git:20260909.3f06aa7 in mdr.lock. Pin the fingerprint instead.

Choose and operate the supported Ray paths in Nebius Physical AI: native Jobs/Core development, guarded Train V2, Cosmos3 native Serve, or Fleet KubeRay.
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
# Ray in Workbench Start with the [consolidated guide](../../../docs/workbench/ray.md). Use this skill to route a Ray request to behavior that current code actually supports. ## Route the request - Native Jobs or Ray Core GPU development: use `docs/testing/fast-source-iteration.md` and the guarded CLIP application under `npa/workflows/workbench/ray-clip-development/`. - Ray Train: load `skills/tools/ray-train-synthetic/SKILL.md`. The shipped path is a synthetic Ray Train V2 application submitted through native Jobs, not an NPA Train service or workflow. - Ray Serve: load `skills/tools/cosmos3-ray-serve/SKILL.md`. Only Cosmos3-Nano has a first-class native Ray Serve path. - KubeRay: load `skills/tools/fleet/SKILL.md`. Fleet supports only the reviewed, fixed CPU RayCluster policy documented in `docs/fleet-kuberay.md`. - Ray Data or Ray Tune: state that no first-class Workbench recipe, CLI, service, workflow, or artifact contract exists. A trusted user may submit their own Ray application through a supported native Jobs environment; do not imply that this makes Data or Tune a supported Workbench capability. …

How to install
mdr add nebius/nebius-physical-ai/ray-workbench@sha256:d713521ec284db7bThe line at the top of this page pins the label git:20260909.3f06aa7, 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.
