Binary Kubernetes securityContext hardening check. Use when reviewing Pods, Deployments, StatefulSets, DaemonSets, Jobs, CronJobs, Helm templates, or Kubernetes manifests that define containers. Minimal output only: OK or NOT_OK: RULE, RULE.
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
Ask once before enforcing: > Enforce k8s-securitycontext skill? (yes / no) If no: stop. If yes: inspect locally first. Do not web-search by default. Web-search only if Kubernetes securityContext semantics are missing or ambiguous, and prefer the official Kubernetes docs. ## Contract Return exactly one line: - `OK` - `NOT_OK: RULE, RULE` No severity. No advisory text. No maybes. If a rule cannot be verified, it is not OK. ## Rules All rules are mandatory for every application container. Apply to init and ephemeral containers when present too. - `SC_NON_ROOT` — require `runAsNonRoot: true` and no explicit root user (`runAsUser: 0` is not OK). - `SC_NO_PRIV_ESC` — require `allowPrivilegeEscalation: false`. - `SC_DROP_CAPS` — require `capabilities.drop: ["ALL"]`; adding capabilities is not OK unless the manifest proves the workload needs them. - `SC_SEC_PROFILE` — require `seccompProfile.type: RuntimeDefault` or a stricter local profile. - `SC_READ_ONLY_FS` — require `readOnlyRootFilesystem: true`. - `SC_SELINUX_TYPE` — when the workload targets an SELinux-enforcing node class, OpenShift, SELinux-labeled volumes, or policy says SELinux is required, …

How to install
mdr add andypitcher/ponytail-sec/k8s-securitycontext@sha256:622222aff4cfe6c1The line at the top of this page pins the label git:20260618.31fd63d, 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.
