Conciseness

The body is lean: three compact tables and a decision tree with zero concept explanations and no padding — it assumes Claude knows what Kubernetes and RBAC are. The only minor redundancy is the opening line restating the description, which does not rise to anchor 4's 'minor instances of over-explanation'.

Actionability

Guidance is mostly concrete: explicit load_skill() paths, specific technique names ('auth can-i --list', 'hostPath escape', '/var/run/docker.sock', 'runC 2019-5736', 'CRI-O 2022-0811'), and a decision tree keyed on entry conditions. Not 5 because the Tooling table lists tools (kubectl, kdigger, peirates, botb) without a single executable command example for any of them.

Workflow Clarity

The single task — route to the correct sub-skill — is unambiguous: the quick-routing tree enumerates every entry condition (pod RCE, SA token, mounted socket, vulnerable runtime) plus an 'Unknown / all of above' fallback. As a single-purpose skill under 50 lines with no destructive or batch operations, no validation checkpoints are required and the simple-skill exception applies.

Progressive Disclosure

No bundle files exist (references/, scripts/, assets/ are absent), and none are needed — the body is under 50 lines with no inlined detail content. Sub-skill references are exactly one level deep and clearly signaled in the table with explicit load_skill paths, and sections are well organized, matching the simple-skill guidance.

Specificity

The description names multiple concrete capabilities — 'pod escape, RBAC abuse, runtime CVE exploitation, socket-mount escape' — and specifies the routing action ('identify the surface (pod-internal RCE vs API-level vs build-pipeline), then load the matching sub-skill'), giving comprehensive coverage for the category. Not 4 because no coverage gaps are evident; the enumerated attack surfaces plus the routing behavior match the comprehensive-anchor example.

Completeness

The 'what' is clear (a routing skill that identifies the attack surface and loads a matching sub-skill), but there is no 'Use when...' clause or equivalent trigger guidance in the description. Per the judging guideline, a missing explicit trigger clause caps completeness at 3; this matches anchor 3 ('clear what but when is missing').

Trigger Term Quality

Natural terms like 'Container', 'Kubernetes', 'pod', 'RBAC', and 'socket-mount' are present, but common synonyms users would say — 'k8s', 'docker', 'cluster' — are absent from the description (they appear only in the when_to_use metadata, not the description field). Good coverage with a few natural terms missing matches anchor 4; a 5 would require synonym-level coverage like 'PDF files, PDFs, .pdf'.

Distinctiveness Conflict Risk

'Pod escape, RBAC abuse, runtime CVE exploitation, socket-mount escape' carves out a clear niche with distinct triggers unlikely to fire for unrelated skills. Not 4 because the attack-surface enumeration makes overlap with generic cloud or general security skills minimal.
