The body is lean and dense — it never explains what Kubernetes/pods/RBAC are and uses compact tables and a short decision tree, so every token earns its place matching the 'lean and efficient' anchor.

Each sub-skill row gives a copy-paste-ready `load_skill("...")` command and the routing tree maps concrete conditions to concrete actions, satisfying the 'fully executable commands; copy-paste ready' anchor for a routing skill.

The decision tree ('Container target identified? -> branches by RCE / SA token / socket / version') gives an unambiguous sequenced routing flow; as a simple routing skill with no destructive steps, no validation checkpoints are required, so it earns 3.

The overview points one level deep to sub-skills via explicit load_skill paths, with content split into clearly organized sections (Sub-skills, Quick routing, Tooling); under 50 lines with no bundle files, this matches the simple-skill allowance for a top score.

Lists multiple concrete attack categories ('pod escape, RBAC abuse, runtime CVE exploitation, socket-mount escape') plus a routing action ('identify the surface ... then load the matching sub-skill'), matching the 'multiple specific concrete actions' anchor.

It clearly states what the skill does (attack-category routing) but provides no explicit 'Use when...' trigger clause, so per guidelines completeness is capped at 2 with only implied 'when' guidance.

Includes relevant domain terms a practitioner would say ('Container', 'Kubernetes', 'pod', 'RBAC', 'CVE', 'socket-mount') but lacks breadth of common variations and aliases, fitting the 'some relevant keywords but missing common variations' anchor.

The container/Kubernetes attack niche is sharply scoped with distinct trigger terms, making it unlikely to fire for unrelated skills, matching the 'clear niche with distinct triggers' anchor.
