{
    "name": "cron",
    "description": "Use when scheduling, listing, removing, or troubleshooting DotCraft Cron jobs with the Cron tool; choose scheduleKind at, every, or daily, set required schedule fields, configure delivery, and recover from Cron validation errors."
}

Cron

Use Cron for scheduled background agent runs that should happen later or repeatedly. Do not use it for a short blocking wait inside the current turn.

Workflow

Choose action: add, list, or remove.
For add, always include scheduleKind.
Keep the schedule fields for the selected kind readable; ignore unrelated auto-filled schedule fields because scheduleKind is authoritative.
Use list before remove when you do not know the job id.

Add Jobs

Kind	Required fields	Optional fields	Use for
`at`	`message`, `delaySeconds`	`name`, `deliver`, `channel`, `toUser`	One-time delay jobs
`every`	`message`, `everySeconds`	`delaySeconds`, `name`, `deliver`, `channel`, `toUser`	Recurring interval jobs
`daily`	`message`, `dailyTime` or `dailyHour`	`dailyMinute`, `timeZone`, `name`, `deliver`, `channel`, `toUser`	Fixed local clock time jobs

Examples:

Cron(action: "add", scheduleKind: "at", message: "Remind me to check the build", delaySeconds: 600)
Cron(action: "add", scheduleKind: "every", message: "Summarize CI status", everySeconds: 3600)
Cron(action: "add", scheduleKind: "every", message: "Ping service", everySeconds: 3600, delaySeconds: 300)
Cron(action: "add", scheduleKind: "daily", message: "Prepare standup notes", dailyTime: "09:30", timeZone: "Asia/Hong_Kong")

Delivery

By default, deliver is true and DotCraft sends the run result back to the creator's current channel or session target. Set deliver: false only when the job should update state without notifying the user. Use channel and toUser only when the user explicitly wants a different delivery target.

List And Remove

Cron(action: "list")
Cron(action: "remove", jobId: "abc12345")

Validation Recovery

Missing scheduleKind: retry with at, every, or daily.
scheduleKind: "at" requires a positive delaySeconds.
scheduleKind: "every" requires a positive everySeconds; delaySeconds is only the first-run delay.
scheduleKind: "daily" requires dailyTime or dailyHour; dailyMinute defaults to 0.
Daily time zones should be IANA ids such as Asia/Hong_Kong; omitted means UTC.
