auditing-ecs-task-metadata-boundaries skillA

auditing-ecs-task-metadata-boundaries is agent-read markdown (skill) from unboundcompute/security-agent-skills: Audit container task credential and metadata boundaries in orchestrated compute such as ECS: a workload that can reach the container credential endpoint or the host instance metadata service to obtain a role broader than the task needs, a task role over-scoped for the workload, a sidecar or co-located container sharing the same credentials, and a server-side request path inside the task that reaches the metadata endpoint. Covers the task credential relative URI, the instance metadata service rea.

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-ecs-task-metadata-boundaries@git:20260827.b5f41a4
Exact content
mdr add unboundcompute/security-agent-skills/auditing-ecs-task-metadata-boundaries@sha256:bc4d308c756e8ea2

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.
