Pi Heartbeat

Pi Heartbeat Extension

Runs a periodic health-check prompt as an isolated subprocess.

Setup

1. Enable via --heartbeat flag, /heartbeat on, or settings.json:

   { "pi-heartbeat": { "enabled": true, "intervalMinutes": 15 } }
   

2. Create a HEARTBEAT.md in your project root with check items:

   # Heartbeat Checklist
   - [ ] Check git status — any uncommitted changes?
   - [ ] Check disk space — anything over 90%?
   - [ ] Review td list for blocked tasks
   

3. If the agent responds with HEARTBEAT_OK, the result is suppressed. Any other response is treated as an alert and sent via pi-channels.

Configuration (settings.json)

{
  "pi-heartbeat": {
    "enabled": false,
    "intervalMinutes": 15,
    "activeHours": { "start": "08:00", "end": "22:00" },
    "route": "ops",
    "showOk": false,
    "prompt": null
  }
