auditing-container-runtime-and-socket-exposure from unboundcompute/security-agent-skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Audit whether a workload can reach the container runtime and thereby control the host: the container runtime socket mounted into a pod or bound into a build or CI container, a privileged sidecar that talks to the runtime to launch or inspect containers, a runtime API exposed over a reachable port, and tooling that needs the runtime and is given it far more broadly than the one operation requires. Covers container hosts where reaching the runtime socket or API grants the ability to start…
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
# Auditing container runtime and socket exposure: a handle on the runtime is a handle on the host Access to the container runtime is access to the host, full stop. Whoever can talk to the runtime socket or API can start a new container that is privileged, mounts the host root filesystem, and shares the host namespaces, and from there they own the node. So mounting the runtime socket into a pod, or binding it into a build or CI container, is not a convenience; it is handing that workload the ability to escape to the host by design, no kernel bug required. The pattern shows up wherever tooling genuinely needs the runtime, image builds, node agents, CI that builds containers, and the mistake is granting broad runtime access for a narrow need. The audit is direct: find every workload that can reach the runtime and treat that reach as host control unless it is tightly brokered. You audit this by locating runtime-socket mounts and runtime-API reachability and confirming nothing untrusted holds them. ## When to use - A workload, build container, or agent is given the container runtime socket or access to the runtime API. …

How to install
mdr add unboundcompute/security-agent-skills/auditing-container-runtime-and-socket-exposure@sha256:092bd3301fcd0c4fThe line at the top of this page pins the label git:20260828.ce55026, 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.
