Intro: CLI SIG
summary
Overview of kubectl internals and how to contribute: entry point lives in kubernetes/cmd/kubectl, commands live under pkg/kubectl/cmd, and the code follows a Cobra-based command pattern with per-command option structs and a complete/validate/run lifecycle so unit tests can inject IO streams. Covers CLI runtime helpers (print flags, resource builder), krew and plugin flow, server-side work like server-side printing and alpha server-side apply, test layers (unit, bash test-cmd, and Ginkgo e2e) with most tests running on every PR.
