using-kubeleash — independently scanned and version-tracked by SaferSkills.
SaferSkills independently audited using-kubeleash (Agent Skill) and scored it 91/100 (green). The audit ran 55 deterministic rules across Security, Supply Chain, Maintenance, Transparency, and Community; it found 1 high-severity and 0 lower-severity findings. The full rule-by-rule trace and per-finding evidence are below. Free, methodology-open.

A fenced bash/python block in SKILL.md carries a natural-language imperative — "now run this", "execute the following command" — directing the agent to execute the fenced content. What looks like documentation becomes an executable payload the agent may run without ever asking you.

The primary manifest — the file an agent reads to learn what this artifact does.
kubeleash is a policy-gated Kubernetes MCP server. Every call is checked against a local, per-context policy before it touches the cluster. Your effective access is what the kubeconfig grants ∩ what the policy allows — kubeleash only ever subtracts.
A denial is intentional policy, not a transient error. Do not route around it with a different verb, resource, or context. If something is denied, report it plainly and stop — or ask the operator to widen the policy.
*If the `k8s_ tools are not present — kubeleash is disabled, failed to load, or not installed — STOP. Do not fall back to kubectl, k9s, oc`, the Kubernetes API, or any other path to the cluster. The absence of the leash is not permission to act unleashed. Report that kubeleash is unavailable and ask the operator to enable or fix it.**
Before acting in a context, call `k8s_capabilities` (optionally with a context). It returns the allowed/denied verbs and resources for that context and performs no cluster call. Doing this first avoids blind denied calls and shows you the shape of the guardrail you're working inside.
Every resource tool shares a common shape:
resource — a plural (pods) or a group/version/kind (apps/v1/Deployment).Use the GVK form to disambiguate CRDs or when a plural is ambiguous.
name, namespace, context — optional. context defaults to the kubeconfigcurrent-context; pass it explicitly to target a specific cluster/context.
namespace for cluster-scoped resources (nodes, namespaces, PVs,ClusterRoles, …); set it to scope namespaced resources.
| Tool | What it does |
|---|---|
k8s_capabilities | What the policy allows in a context (no cluster call). Start here. |
k8s_list | List objects; optional namespace, labelSelector, fieldSelector. |
k8s_get | Fetch one object by name. |
k8s_apply | Server-side apply a manifest — creates or updates by existence. |
k8s_delete | Delete one object by name. |
k8s_logs | Read a pod's logs (one-shot). Bounded: tailLines (default 100, operator-capped), plus container, previous, sinceSeconds, timestamps. |
k8s_scale | Set a workload's replica count via the scale subresource. Gated as the scale verb (distinct from update). |
k8s_exec | Run a one-shot command in a pod container (no TTY, no stdin). Returns exit code + stdout + stderr; a non-zero exit is data, not an error. Bounded by an operator timeout and output byte cap. Specify container when the pod has more than one. |
A denied call returns one of two reasons — respond to them differently:
forbidden this. Stop. Do not retry or look for a workaround.
it. The operator may simply not have granted it — surface this to the human; they may choose to widen the policy.
k8s_get / k8s_list to understand currentstate before any k8s_apply or k8s_delete.
k8s_delete, k8s_scale, ork8s_exec, state what you are about to change and why, and prefer the narrowest action that accomplishes the goal.
existing object is updated, a missing one is created — each gated by the matching create/update verb, so a policy can grant create-but-not-update.
one session; each call is evaluated against its resolved context.
