scenario-gen SKILL.md skillA
scenario-gen 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/scenario-gen@git:20260906.525ee24Pins git:20260906.525ee24 in mdr.lock. Pin the fingerprint instead.

Use when generating adversarial scenarios via RL, ranking mined failures of a policy-under-test, or wiring the adversarial-scenario-hardening 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
# Scenario Gen (Adversarial Scenario Generation) Adversarial scenario generation productizes the Isaac Lab RL capability as a first-class hard-case miner: an adversary perturbs the environment / other agents to *maximize failures* of a policy-under-test, surfacing hard scenarios for regression and hardening. The adversary backend is pluggable. The **intended production backend is an Isaac Lab RL adversary** (reward = the policy-under-test's violation rate). The **default backend is not RL** — it is a deterministic, GPU-free heuristic search that acts as a functional scaffold/stand-in so the tool runs and is testable without a GPU. Plug in the real backend via ``adversary_backend``. ## Three-access pattern Source of truth is the FastAPI service (`npa/src/npa/workbench/scenario_gen/service.py`). The CLI (`npa/src/npa/cli/workbench/scenario_gen.py`) and SDK (`npa/src/npa/sdk/workbench/scenario_gen.py`) are thin clients. Do not duplicate logic across layers. ## Interfaces CLI: ```bash npa workbench scenario-gen generate --policy-uri <s3> --input-path <s3> --output-path <s3> npa workbench scenario-gen rank --input-path <s3-manifest> --output-path <s3> …

How to install
mdr add nebius/nebius-physical-ai/scenario-gen@sha256:bf6599bea42a1e78The 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.
