Scheduled Task Skill

You can manage scheduled tasks to automatically execute operations at specified times.

IMPORTANT RULES

  1. ONE task per conversation - Each conversation can only have ONE scheduled task
  2. Output commands directly - Do NOT wrap commands in markdown code blocks
  3. ALWAYS include closing tags -
    [CRON_CREATE]
    MUST end with
    [/CRON_CREATE]
    ,
    [CRON_UPDATE]
    MUST end with
    [/CRON_UPDATE]

Workflow

This is a two-step workflow. Each step is one message turn.

Step 1: Query Output

[CRON_LIST]
(nothing else in this message) and wait for the system response.

Step 2: Act (based on system response)

  • "No scheduled tasks" → Immediately output
    [CRON_CREATE]
    in this message. Do NOT ask the user for extra confirmation — they already told you what they want.
  • Task already exists and user wants to change it → Output
    [CRON_UPDATE: <job-id>]
    to modify in place.
  • Task already exists and user wants something different → Ask the user how to proceed.

Create: [CRON_CREATE]

Output this format DIRECTLY (not in code blocks):

[CRON_CREATE] name: Task name schedule: Cron expression schedule_description: Human-readable description message: Message content [/CRON_CREATE]

Required fields:

  • name
    : Short descriptive name
  • schedule
    : Valid cron expression (see reference below)
  • schedule_description
    : Human-readable schedule (e.g., "Every Monday at 9:00 AM")
  • message
    : The prompt sent to the AI when triggered — must be a complete, self-contained instruction

How to write

message
:

The

message
is what the AI receives each time the task fires. It must tell the AI exactly what to do — NOT restate the user's request.

User says❌ Bad message✅ Good message
"Send me hello every day at 10am"Send me helloReply with exactly: Hello!
"Remind me to drink water daily"Remind me to drink waterReply with a friendly reminder to drink water
"Summarize AI news every Monday"Summarize AI newsSearch for the latest AI news from this week and produce a concise bullet-point summary report

Example (output EXACTLY like this, no code blocks):

[CRON_CREATE] name: Weekly Meeting Reminder schedule: 0 9 * * MON schedule_description: Every Monday at 9:00 AM message: Reply with a short weekly meeting reminder that includes the current date and time. [/CRON_CREATE]

Update: [CRON_UPDATE]

Use this to modify an existing task in place (preserves all associated conversations).

[CRON_UPDATE: <job-id>] name: Updated task name schedule: New cron expression schedule_description: Human-readable description message: Updated message content [/CRON_UPDATE]

Replace

<job-id>
with the real job ID from
[CRON_LIST]
result. All four fields are required — provide the full updated values.

Query: [CRON_LIST]

Output

[CRON_LIST]
directly. The system will return the result in a follow-up message.

Cron Expression

Format:

minute hour day-of-month month day-of-week
— e.g.
0 9 * * MON-FRI
= weekdays at 9:00 AM.
