Uses the skills.sh CLI (npx skills) to install all skills from the Kit repository.

     providers, agents, tools, and MCP integration.

Example:
  kit skill`,
	RunE: runSkill,
}

func init() {
	rootCmd.AddCommand(skillCmd)
}

func runSkill(_ *cobra.Command, _ []string) error {
	npx, err := exec.LookPath("npx")
	if err != nil {
		return fmt.Errorf("npx not found in PATH — install Node.js to use this command: %w", err)
	}

	args := []string{
		"skills",
		"add",
		"mark3labs/kit",
	}

	cmd := exec.Command(npx, args...)
	cmd.Stdin = os.Stdin
	cmd.Stdout = os.Stdout
	cmd.Stderr = os.Stderr

	if err := cmd.Run(); err != nil {
		return fmt.Errorf("skills install failed: %w", err)
