mergeable-please

Drive a GitHub pull request toward mergeable. Run when asked to "make a PR mergeable", "loop until the PR is ready", "fix the PR until CI/conflicts/reviews pass", or similar. Repeatedly runs `mergeable-please check`, resolves each reported blocker (conflicts, behind-base, failing/pending required CI, reviewer-loop goals), and loops until the tool reports satisfied.

Golang CLI command tree library using spf13/cobra — cobra.Command, RunE vs Run, PersistentPreRunE hook chain, Args validators (NoArgs, ExactArgs, MatchAll, custom), persistent vs local flags, command groups, ValidArgsFunction, RegisterFlagCompletionFunc, ShellCompDirective, usage/help template customization, man-page and markdown doc generation, and testing with SetArgs/SetOut/SetErr. Apply when using or adopting spf13/cobra, or when the codebase imports `github.com/spf13/cobra`. For configuration layering alongside cobra, see the `samber/cc-skills-golang@golang-spf13-viper` skill. For general CLI architecture (project layout, exit codes, signal handling, I/O patterns), see `samber/cc-skills-golang@golang-cli`.
