Heartbeat

Sidebar → Heartbeats → New

Heartbeat lets an agent wake itself up on a fixed interval and run a prompt without any user message — useful for monitoring, daily summaries, scheduled outreach, or any "check in periodically and do X" workflow.

When to Use Heartbeat vs Scheduler

Need	Use
Run a fixed prompt every N seconds/minutes	Heartbeat
Run on cron (e.g. weekdays at 9am)	Scheduler tool
One-off reminder	Scheduler tool

Heartbeat is a higher-level loop attached to an agent + target; the Scheduler tool is a lower-level cron primitive the agent can call itself.

Configuration

Field	Description
Name	Display name
Agent	Which agent should run on each tick
Target	A specific channel user, web session, or working directory
Interval	Tick period (seconds/minutes/hours)
Prompt	Prompt template the agent receives on each tick
Enabled	Toggle without deleting

Examples

• Status digest — every 1h, summarize new messages in a busy Lark group and drop the digest in a "summary" thread
• Watchdog — every 5min, query a health endpoint via the Web tool; ping you only on failure
• Standup buddy — every weekday morning, ask the user how yesterday went and write a note

Notes

• Each heartbeat target gets its own conversation thread (isolated history)
• Combine with Memory so the agent learns from each tick
• For stateful reminders/schedules driven by conversation content, use Agenda instead
• Disable a heartbeat to pause without losing its config
