cosmos3-nano-sim-bimanual-post-training SKILL.md skillA
cosmos3-nano-sim-bimanual-post-training from nvidia/cosmos-framework is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Train Cosmos3 Nano Sim Bimanual from Cosmos3-Nano with Cosmos Framework's four native stage TOMLs and a local training bundle. Covers data preparation, initialization, training, checkpoint handoffs, resume and student export.
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
# Post-train Cosmos3-Nano-Sim-Bimanual Train an action-conditioned world model that predicts the visual consequences of bimanual actions. It consumes a task description, RGB observations and an aligned action trajectory, and produces video rather than robot actions. The worked chain starts from Cosmos3-Nano and runs Stage 0 through Stage 3. ## Choose your starting point | Goal | Start with | Follow | | ----------------------------------- | -------------------------------------------------------- | ----------------------------------------------- | | Start a new four-stage training run | Cosmos3-Nano and a completed local bundle | [Stage 0 Quickstart](#quickstart-train-stage-0) | | Continue an existing chain | Your completed stage checkpoint and saved configuration | [Continue training](#continue-training) | | Generate video | Released Bimanual model or your exported Stage 3 student | [Inference](../inference/SKILL.md) | Use the [data contract](references/data-contract.md) for action meaning, …

How to install
mdr add nvidia/cosmos-framework/cosmos3-nano-sim-bimanual-post-training@sha256:36a2bcdfa3a9ba2bThe line at the top of this page pins the label git:20261021.7e918d7, 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.
