sim2real-engine SKILL.md skillA
sim2real-engine 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/sim2real-engine@git:20261029.fe9128ePins git:20261029.fe9128e in mdr.lock. Pin the fingerprint instead.

Use when navigating, reviewing, or changing the compositional Sim2Real workflow, stateless stage adapters, durable standard-runtime resume, ComponentRecords, and S3 lineage.
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
# Compositional Sim2Real engine The canonical engine surface is the ordinary workflow `workflows/main/sim2real.yaml`. Its leaf states call `npa.workflows.sim2real.workflow_stage`; S3/content-addressed evidence primitives live in `workflow_io`. The shared `npa_workflow` interpreter/runtime owns loops, parallel waves, SkyPilot jobs, ledger persistence, and resume. The small `engine.py` facade and bounded `legacy_*` modules remain compatibility surfaces for archived runs. New canonical states must never call `run_preamble`, `run_inner_loop`, `run_single_outer_iteration`, `run_finalize`, or spawn sibling Jobs. ## Stage map | Stage | Canonical record | Adapter boundary | | ---: | --- | --- | | 1 | `stage_01_trigger` | task-aligned trigger/seed validation | | 2 | `stage_02_assets` | task/assets/camera/strict-success contract | | 3 | `stage_03_augment` | real Cosmos Transfer 2.5 | | 4 | `stage_04_envs_raw` | parallel raw EnvGen shards | | 5 | `stage_05_envs_train` | sealed train/validation/gold split | | 6 | `stage_06_tokens` | explicit S3 token/scenario manifest | | 7 | `stage_07_actions_train` | real Isaac multi-camera rollout | …

How to install
mdr add nebius/nebius-physical-ai/sim2real-engine@sha256:9962ceb2aa91ac26The line at the top of this page pins the label git:20261029.fe9128e, 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.
