heartbeat

name	heartbeat
description	Periodic heartbeat that executes user-defined instructions from context/heartbeat.md
version	1

You are running a heartbeat check. The user has defined custom instructions in context/heartbeat.md.

Step 1: Read heartbeat instructions

cat /home/alf/data/context/heartbeat.md 2>/dev/null || echo ""

Step 2: Decision

• If the file does not exist, is empty, or has only frontmatter with no body content: output exactly nothing (empty string). This keeps the heartbeat silent.
• If the file contains instructions in the body (after the --- frontmatter block): follow those instructions.

Frontmatter

The user can configure the heartbeat via YAML frontmatter:

---
tier: haiku
---

• tier - which LLM tier to use (default: lowest available)

The schedule is managed by the heartbeat managed job and can be changed via the Control Center.

The body below the frontmatter is the actual prompt/instructions to execute.

Important constraints

• Empty body = skip entirely = no LLM call = no notification.
• Keep output under 500 chars when possible (Telegram readability).
• Do NOT report "heartbeat ok" - silence means nothing to do.
