kubernetes-operator

Use when building a Kubernetes Operator — custom controllers that reconcile CRD state. Triggers on "build an operator", "CRD design", "reconcile loop", "controller-runtime", "kubebuilder", "operator-sdk", "metacontroller", "KOPF", "operator capability levels", or "custom resource". Ships CRD validator, reconcile-loop linter, and OperatorHub capability auditor (all stdlib Python), 4 references on the operator pattern + CRD design + reconcile patterns + tooling landscape, and a /operator-audit slash command. NOT a generic k8s skill — specifically the Operator pattern.

Quality

Content

92%Weight 40%Scale 1-5

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

A well-structured, highly actionable body with executable commands, validated workflows, and clean one-level-deep progressive disclosure. The only weakness is minor redundancy between the failure-modes list and the anti-patterns section.

DimensionReasoningScore

Conciseness

Largely lean and operator-specific with useful framing, but the 'Operators that fail' 7-point list overlaps the later 'Anti-patterns' section, a minor redundancy that could be trimmed. Not a 5 because of this duplicated content; not a 3 because almost everything earns its place.

4 / 5

Actionability

Fully executable: copy-paste bash invocations in Quick start, per-tool check lists, numbered workflows with real commands, and verified template assets (crd_template.yaml, reconcile_skeleton.go).

5 / 5

Workflow Clarity

Three numbered workflows with explicit validation gates and feedback loops (step 4 'Fix every WARN before writing controller code', Workflow 2 FAIL/WARN triage, kind-cluster test step), satisfying the batch/destructive validation requirement.

5 / 5

Progressive Disclosure

Clear overview with one-level-deep, well-signaled references ('See references/crd_design.md for full detail. Quick rules:') and a consolidated References section; all referenced scripts/assets/reference files verified present on disk.

Description

100%Weight 40%Scale 1-5

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

A strong, third-person description that explicitly states both what the skill does and when to invoke it, with comprehensive natural trigger terms and explicit conflict-disambiguation. It comprehensively enumerates concrete shipped tools and references.

DimensionReasoningScore

Specificity

Names the domain ('custom controllers that reconcile CRD state') and multiple concrete artifacts ('CRD validator, reconcile-loop linter, and OperatorHub capability auditor'), giving comprehensive coverage of specific actions.

5 / 5

Completeness

Explicitly answers both what ('building a Kubernetes Operator', ships three tools + references + slash command) and when ('Use when building…', 'Triggers on…') with concrete trigger phrases.

5 / 5

Trigger Term Quality

Comprehensive natural trigger terms including synonyms and tool names ('build an operator', 'reconcile loop', 'controller-runtime', 'kubebuilder', 'operator-sdk', 'metacontroller', 'KOPF', 'custom resource').

5 / 5

Distinctiveness Conflict Risk

Carves a clear niche with explicit disambiguation ('NOT a generic k8s skill — specifically the Operator pattern') and distinct operator-specific triggers, minimizing conflict risk.
