  "description": "AgentMux's own cross-agent cron — NOT the same tool as the native (non-mcp__agentmux__-prefixed) CronCreate your harness may also expose, which schedules only your own session's future turn. Use this one specifically to target a DIFFERENT agent (or when you need AgentMux-persisted delivery independent of any single session). Creates a persistent scheduled cron job that survives agent pane restarts. Fires the prompt on a UTC cron schedule by injecting it into the target agent. Unlike Loop, cron jobs persist as long as agentmux-srv is running. Returns a job id and the next scheduled fire time. If you're scheduling your OWN future turn instead, prefer the native CronCreate/ScheduleWakeup tools — no cross-agent envelope overhead.",
