ray-train-synthetic SKILL.md skillA
ray-train-synthetic 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-train-synthetic@git:20260907.41d5f85Pins git:20260907.41d5f85 in mdr.lock. Pin the fingerprint instead.

Run or review the native Ray Train synthetic distributed CUDA reference, its S3 checkpoints, optimizer recovery, and factual Rerun metrics.
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
# Native Ray Train reference Use [the reference guide](../../../npa/workflows/workbench/ray-train-synthetic/README.md). This is a guarded application example: native Ray Jobs delivers source and owns submission/status/logs/stop; SkyPilot owns the development hosts and service task. It adds no NPA Jobs wrapper, controller, CLI group, image or workflow catalog. Use `npa.workflow` for production composition beyond this single application. Read `health-preflight`, `gpu-selection`, `skypilot-workflows`, `third-party-eula-preflight`, and `teardown-and-cost` before live operation. Preflight the selected project's exact workload bucket and prefix; do not use a different project's Terraform-state or trajectory bucket as training storage. The pins are application Ray 2.58.0 / Train V2, Torch 2.13.0+cu130 in the digest-pinned upstream PyTorch image, Rerun 0.31.4 and Pillow 12.3.0. The driver and every new or restarted worker enforce the Torch pin at run time. Keep application Ray separate from SkyPilot's management environment and reserved ports. Pure Python source changes use native Jobs `--working-dir`; native ABI changes require a …

How to install
mdr add nebius/nebius-physical-ai/ray-train-synthetic@sha256:9e3ad116380c399fThe line at the top of this page pins the label git:20260907.41d5f85, 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.
