auditing-container-image-provenance is agent-read markdown (skill) from unboundcompute/security-agent-skills: Audit how a cluster decides which container images to trust and run: an image referenced by a mutable tag rather than a content digest, a workload pulling from a registry that admits unsigned or unverified images, a signature or attestation policy that is configured but not enforced at admission, and a base image or layer whose origin the pipeline never verified. Covers Kubernetes and container platforms where the image a workload runs is the code that runs, and where tag mutability, signing, an.

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 unboundcompute/security-agent-skills/auditing-container-image-provenance@git:20260828.ce55026
Exact content
mdr add unboundcompute/security-agent-skills/auditing-container-image-provenance@sha256:ac7773da97964bd0

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.
