Kubernetes Skill

Production Kubernetes management — from Helm chart authoring to GitOps with ArgoCD and advanced deployment strategies.

RULE: Always show manifests/plan before applying. Never run kubectl apply without showing what changes.

🚧 Status: Stub — implementation pending

This reference skill has the structure but the snippet content is still being filled in (you'll see <!-- TODO --> placeholders below). It activates and tells Claude the topic exists, but won't yield deep snippets yet.

Want to help? Pick any TODO, write the snippet, open a PR. See CONTRIBUTING.md. Each contribution moves the skill closer to "Ready" status.
