newton skillA
newton is agent-read markdown (skill) from nebius/nebius-physical-ai: Use when working on Newton physics engine workbench stages (teacher training, demo generation, evaluation), the Newton XPBD simulation pipeline, or the npa workbench newton CLI..
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
What the file says
# Newton Newton is the physics engine tool for teacher policy training, demonstration generation, and policy evaluation in simulation. The three core stages (`train-teacher`, `generate-demos`, `eval`) are currently stubs: they expose the intended argument signatures but exit with a clear "not yet implemented" message until the Newton simulation pipeline lands (tracking issue nebius/nebius-physical-ai#499). Real physics validation (a double-pendulum XPBD simulation) runs on CPU via the installed Newton package — no GPU required for the validation path. ## Interfaces - CLI: `npa workbench newton <train-teacher|generate-demos|eval> --help` - Python SDK (workbench-first): `npa.workbench.newton` (`train_teacher`, `generate_demos`, `evaluate`) - Workflow module: `npa.workflows.byof.newton_pipeline` (argument validation, stub-manifest plumbing, argparse entrypoint) ## Conventions - The CLI lives at `npa.cli.workbench.newton` (multi-command package form for new tools); the SDK surface lives at `npa.workbench.newton` and does not go through `make_cli_wrapper`. - Stub stages write a `not_implemented` manifest to the requested …

How to install
mdr add nebius/nebius-physical-ai/newton@git:20260923.d7dd301mdr add nebius/nebius-physical-ai/newton@sha256:3762c3c40de10734Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
