Which Go CLI framework is best for Kubernetes alignment?

Cobra is the primary recommendation for Kubernetes-native tools as it aligns closely with kubectl conventions and offers the highest ecosystem maturity.

Is shell completion supported by these frameworks?

Cobra and Kong have built-in shell completion support, while urfave/cli typically requires a plugin to achieve similar functionality.

Does this skill provide configuration management advice?

Yes, it includes specific implementation patterns for using Viper to manage layered configurations, which is essential for cloud-native tools.

How does Kong differ from Cobra in Go development?

Kong focuses on high type safety and lower learning curves, whereas Cobra provides more robust nested subcommands and deeper integration with the Kubernetes ecosystem.
