cosmos3-nano-sim-transfer-troubleshooting SKILL.md skillA
cosmos3-nano-sim-transfer-troubleshooting from nvidia/cosmos-framework is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add nvidia/cosmos-framework/cosmos3-nano-sim-transfer-troubleshooting@git:20261021.7e918d7Pins git:20261021.7e918d7 in mdr.lock. Pin the fingerprint instead.

Diagnose Cosmos3-Nano-Sim-Transfer setup, checkpoint loading, media alignment, training-state and output failures in an existing workflow.
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
# Troubleshoot Cosmos3-Nano-Sim-Transfer
Start with the first failing operation and preserve the last completed
checkpoint and existing outputs. Compare the effective inputs and model
identity with the [shared contract](../shared/model-contract.md).
| Symptom | Reference |
| -------------------------------------------------------- | --------------------------------------- |
| Import failure, CUDA unavailable, missing library | [Runtime](#runtime) |
| Unknown model alias or incompatible weights | [Model and runtime](#model-and-runtime) |
| Missing, distorted or drifting control | [Media and data](#media-and-data) |
| Ignored flags, overwritten output or unexpected geometry | [Inference](#inference) |
| Wrong restart state or training failure | [Training state](#training-state) |
The [failure table](references/failure-playbook.md) lists specific errors.
## Runtime
Identify the checkout and interpreter used by the failing command:
```bash
cd "${FRAMEWORK_DIR:?Set the Cosmos Framework checkout root}"

How to install
mdr add nvidia/cosmos-framework/cosmos3-nano-sim-transfer-troubleshooting@sha256:c1dc910ae26f40a1The 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.
