Name: secure-image-build
Author: nebius

secure-image-build is agent-read markdown (skill) from nebius/nebius-physical-ai: Use whenever an NPA container image is built, tagged, pushed, copied, or promoted, including public full-SHA development builds, release publication, build scripts, and image-producing GitHub Actions workflows. Enforce mandatory safety gates and refuse insecure or restricted publication..

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.

How to install

Latest version

mdr add nebius/nebius-physical-ai/secure-image-build@git:20260906.9a78a75

Exact content

mdr add nebius/nebius-physical-ai/secure-image-build@sha256:b64c182b8aeb2958

Pin 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.
