OpenClaw heartbeat is very useful as a periodic agent turn / awareness loop, but it is easy for users to misunderstand it as a system health check or uptime signal. A heartbeat that runs inside the same OpenClaw/Gateway environment can help with:

  • background task follow-up
  • interruption detection
  • lightweight proactive reminders But it cannot prove:
  • host power is on
  • the machine itself is alive
  • the scheduler is still running
  • OpenClaw/Gateway can self-report after it has already gone down So today there are two related gaps:
  1. Semantics gap Heartbeat is conceptually "periodic awareness", not true uptime monitoring, but this boundary is easy to miss.
  2. Workflow gap In practice, heartbeat is often only useful while a long-running/background task is active. A task-scoped mode would be more useful than always-on periodic polling for many users.

What I expected vs what heartbeat actually does

What I initially expected:

  • something closer to a watchdog / liveness signal What heartbeat actually does well:
  • periodic agent turns in the main session
  • checking whether there is anything worth surfacing
  • reporting stalled tasks, finished subagents, or blocked work
  • sending nothing when the correct response is HEARTBEAT_OK That behavior is good. The issue is mainly that users can still interpret "heartbeat" as "system is alive", which is not what same-host heartbeat can guarantee.

Fix Plan

To address the semantics gap and workflow gap, we can introduce a new task-scoped heartbeat mode and clarify the documentation.

Step-by-Step Solution

  • Introduce a new task_scoped parameter to the heartbeat configuration:
heartbeat_config = {
    'interval': 60,  # seconds
    'task_scoped': True  # new parameter
}
  • Modify the heartbeat logic to only run when a long-running task is active:
if heartbeat_config['task_scoped'] and not is_task_active():
    # skip heartbeat
    return
  • Update the documentation to clearly explain the difference between heartbeat and uptime monitoring:
### Heartbeat
Periodic awareness loop for background tasks. Does not guarantee system uptime or liveness.
  • Consider introducing a separate uptime monitoring system, such as a watchdog or liveness signal, to address the workflow gap.

Verification

To verify the fix, test the new task-scoped heartbeat mode by:

  • Configuring a long-running task with task_scoped set to True
  • Verifying that the heartbeat only runs when the task is active
  • Testing the documentation updates to ensure clarity on the heartbeat's purpose

Extra Tips

  • Consider adding a warning or notice to the documentation to highlight the limitations of the same-host heartbeat.
  • Review existing user configurations to identify potential misuse of the heartbeat feature and provide guidance on migrating to the new task-scoped mode.
