burst from nebius/nebius-physical-ai is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Use to run one gang-scheduled multi-node GPU job through SkyPilot without authoring a workflow — `npa burst submit` wires torchrun rendezvous across nodes, while `submit-yaml` supports one task, `${VAR}` substitution, and optional generic registry credentials.
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
# Burst (one coupled multi-node GPU job) Burst is the escape hatch for a **single** distributed task: gang-schedule N nodes, run one command under `torchrun`, get logs, exit. It is deliberately not a workflow surface — there is no plan, no stage graph, no decision artifact, and nothing for a `toolRef` to describe. **If you need a second stage, you need a workflow.** Author an `npa.workflow/v0.0.1` spec under `workflows/` instead (`skills/workflows/author-npa-workflow/SKILL.md`). `submit-yaml` rejects multi-task documents, and a guardrail pins the example set so a pipeline cannot quietly grow here. ## Submit a distributed run directly ```bash npa burst submit \ --image <registry>/<image>:<tag> \ --nodes 2 \ --gpu-per-node H100:8 \ --entrypoint "python train.py --config configs/run.yaml" \ --name <job-name> \ --json ``` All four of `--image`, `--nodes`, `--gpu-per-node`, `--entrypoint` are required. A plain image reference is rendered as `docker:<image>`. `--json` prints only the serialized job handle, which is what you want when scripting. **The entrypoint runs under `torchrun`, not directly.** Burst derives the …

How to install
mdr add nebius/nebius-physical-ai/burst@sha256:b77ae6e35681371fThe line at the top of this page pins the label git:20260906.525ee24, 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.
