Conciseness

The Workflow steps are lean executable commands, but the Overview re-explains RBAC basics Claude already knows ('governs what every user and service account may do via Role/ClusterRole rules...') and the dangerous-primitives list is duplicated as both Overview bullets and an end-of-file 'Dangerous RBAC Primitives Reference' table. Not 4 because the duplicated reference table and conceptual padding exceed 'minor' over-explanation; not 2 because the bulk is genuinely efficient command content rather than severely padded.

Actionability

Packed with copy-paste-ready, executable bash (kubectl, jq, grep, rbac-police) including a complete apply-able privileged-pod PoC manifest and krew/curl install commands covering the common audit cases. Not 4 because guidance is fully executable across the common cases rather than having material gaps.

Workflow Clarity

Seven steps are clearly sequenced and a final Validation Criteria checklist exists, but this is a destructive skill (Step 6 schedules a privileged host-mounting pod reading /etc/shadow) with no inline validate->fix->retry feedback loops; validation is largely post-hoc rather than per-step. Capped at 3 per the destructive-operations missing-feedback-loops rule; not 4 because the lack of inline recovery loops in a destructive context is more than a minor gap.

Progressive Disclosure

The body is well-sectioned (Overview, When to Use, Prerequisites, 7-step Workflow, reference tables), but bundle files references/api-reference.md, references/standards.md, and scripts/agent.py exist yet are never linked or signaled from the body, and the primitives list and MITRE table are inlined in SKILL.md despite standards.md already holding them. Not 4 because references are entirely unsignaled and content that belongs in separate files is inlined/duplicated; not 2 because section structure is solid rather than 'minimal'.

Specificity

Lists multiple concrete actions ('Finds over-permissive RBAC roles and service-account token abuse paths', 'tracing which subjects can escalate toward cluster-admin') and names four specific tools (kubectl auth can-i, rbac-police, kubectl-who-can, rakkess), giving comprehensive coverage of the audit task. Not 4 because coverage is comprehensive rather than having minor gaps.

Completeness

Explicitly answers 'what' (finds over-permissive roles and token abuse paths, traces escalation toward cluster-admin) and 'when' ('Use when reviewing who can escalate privileges... hunting exploitable RoleBindings... or validating least privilege after an RBAC change') with concrete trigger phrases. Not 4 because both what and when are explicit and concrete, and a negative boundary is even provided.

Trigger Term Quality

Includes an explicit keyword list ('RBAC, ClusterRoleBinding, service account token, auth can-i, rbac-police, escalate, bind, impersonate') plus natural trigger phrases ('reviewing who can escalate privileges', 'validating least privilege after an RBAC change') with synonyms. Not 4 because natural terms and synonyms are comprehensive for the domain.

Distinctiveness Conflict Risk

Occupies a clear niche (Kubernetes RBAC privilege-escalation auditing) and explicitly redirects the adjacent task elsewhere ('Do not use for designing and applying hardened RBAC - use implementing-rbac-hardening-for-kubernetes'), minimizing conflict with sibling skills. Not 4 because the explicit negative boundary drives conflict risk to minimal.
