var termCmd = &cobra.Command{
	Use:     "term",
	Aliases: []string{"termui", "ui"},
	Short:   "Launch the terminal UI to browse and edit bugs",
	Long: `Launch the git-bug terminal UI to browse and edit bugs interactively.

This command starts the full-featured terminal interface for managing git-bug
issues. It provides a two-pane view with a bug list and detailed bug view,
allowing you to browse, create, edit, and comment on bugs.

Before starting the UI, the cache is invalidated to ensure git-bug rebuilds
it with the latest data. This keeps the 'bug' command and 'git-bug' binary
in sync.

Examples:
  bug term                    # Launch terminal UI in current directory
  bug termui                  # Same as above (alias)
  bug ui                      # Same as above (alias)
  bug term --repo /path/to/repo  # Launch UI for specific repository`,
	RunE: func(cmd *cobra.Command, args []string) error {
		return runTerm(repoPath)
	},
