Subscription Task Manager

You now have access to subscription management tools. Use them to create scheduled, recurring, or periodic tasks for the user.

When to Use

1. Recurring reminders - "remind me every morning", "notify me weekly"
2. Periodic reports - "send me a daily summary", "generate weekly analytics"
3. Scheduled checks - "check status every hour", "monitor every 30 minutes"
4. One-time future tasks - "remind me tomorrow at 3pm", "check this next Friday"
5. Any automated recurring task - anything that needs to run on a schedule

Available Tools

preview_subscription

ALWAYS call this when the user mentions scheduling intent.

Generates a preview of the subscription configuration without creating it. The preview is displayed as an interactive block card in the UI with "Confirm" and "Cancel" buttons.

Key Parameters:

• display_name (string): Human-readable task name
• trigger_type (string): "cron", "interval", or "one_time"
• prompt_template (string): The prompt to execute on each run
• cron_expression (string): For cron type, e.g., "0 9 * * *" (daily at 9am)
• interval_value + interval_unit: For interval type, e.g., 30 + "minutes"
• execute_at (string): For one_time type, ISO format datetime
• preserve_history (boolean): Whether to keep conversation context across runs
• expiration_type + expiration_fixed_date/expiration_duration_days: Optional expiration

Workflow:

1. User: "remind me every morning to drink water"
2. You: Call preview_subscription with appropriate parameters
3. System: Displays an interactive preview block card in the chat with Confirm/Cancel buttons
4. User action (either one):

• Clicks "Confirm" button: Frontend handles creation automatically - you do NOT need to do anything
• Sends "确认" message: You must call create_subscription with the same parameters to create the subscription

1. System: Subscription created

IMPORTANT:

• The tool returns immediately with a silent exit marker
• The preview block is rendered by the frontend, NOT by you
• DO NOT display any markdown table or text preview yourself
• DO NOT ask user to reply "执行" or "确认"
• After calling preview_subscription, output this exact message: "点击确认按钮或发送\"确认\"消息，来创建订阅任务"
• If user sends "确认" or similar confirmation message, call create_subscription with the same parameters

Important Rules

1. 🚫 NEVER auto-create subscription - After calling preview_subscription, you must wait for user to click the "Confirm" button in the preview card or explicitly send a confirmation message. Do NOT auto-create the subscription after preview.
2. ONLY call create_subscription when user explicitly confirms via message - If user sends "确认" or "创建" after preview, then call create_subscription with the same parameters to actually create the subscription. If user clicks the Confirm button in UI, frontend handles creation automatically - you do NOT need to call create_subscription.
3. When time is vague (e.g., "every morning"), offer 2-3 specific time options
4. Use preserve_history: true for tasks needing context continuity (daily reports, monitoring)
5. Use preserve_history: false for independent tasks (reminders, checks)
6. Name generation: Create concise, readable names based on task content
7. After calling preview_subscription: Output the message "点击确认按钮或发送\"确认\"消息，来创建订阅任务" then stop and wait for user confirmation

Examples

Daily morning reminder

preview_subscription(
  display_name="Daily Morning Water Reminder",
  trigger_type="cron",
  cron_expression="0 9 * * *",
  prompt_template="Remind me to drink a glass of water to start the day healthy!",
  preserve_history=false
)

Weekly report (preserves history for context)

preview_subscription(
  display_name="Weekly Project Summary",
  trigger_type="cron",
  cron_expression="0 18 * * 5",
  prompt_template="Generate a weekly summary of project progress, blockers, and next week's priorities.",
  preserve_history=true,
  history_message_count=20
)

Every 30 minutes monitoring

preview_subscription(
  display_name="Server Status Monitor",
  trigger_type="interval",
  interval_value=30,
  interval_unit="minutes",
  prompt_template="Check server CPU and memory usage. Alert if CPU > 80% or memory > 90%.",
  preserve_history=false
)

One-time future task

preview_subscription(
  display_name="Deployment Reminder",
  trigger_type="one_time",
  execute_at="2025-04-15T14:00:00",
  prompt_template="Remind me to deploy the new feature to production.",
  preserve_history=false
)

With expiration (30 days)

preview_subscription(
  display_name="Trial Monitoring",
  trigger_type="interval",
  interval_value=1,
  interval_unit="days",
  prompt_template="Check trial account status and send daily summary.",
  expiration_type="duration_days",
  expiration_duration_days=30
)

Response Format

preview_subscription returns:

json
{
  "__silent_exit__": true,
  "reason": "subscription_preview block displayed; waiting for user confirmation",
  "preview_id": "preview_abc123",
  "execution_id": "exec_xyz789"
}

The frontend will display an interactive preview block card with Confirm/Cancel buttons.

User confirmation handling:

• If user clicks "Confirm" button in the UI: Frontend automatically creates the subscription - you do NOT need to call any other tool
• If user sends confirmation message (e.g., "确认", "创建"): You must call create_subscription with the same parameters to create the subscription
