Notes

• command uses the shell command handler and is validated at creation time.
• Currently allowed base commands are: echo, date, uptime, df, free, ps, curl, wget.
• Use scheduler for recurring or cron-style command execution.
• Use reminder for user-facing alerts and notifications; the two skills are intentionally different.
• This skill automates commands. It is not a countdown timer or reminder delivery surface.
