Preview Execution monitoring

We're building live execution health for every listing: tool-call success rate, median latency, uptime, and last-checked timestamps, measured, not self-reported. It isn't live yet, so we don't show numbers we can't stand behind.

About

Heartbeat

Periodic agent wake-up to check for tasks in HEARTBEAT.md.

How It Works

  1. Every 30 minutes, the scheduler triggers this skill
  2. Read HEARTBEAT.md from the workspace root
  3. If file is empty or has no actionable content → reply HEARTBEAT_OK and stop
  4. If file has tasks → execute them one by one
  5. Mark completed tasks by moving them to the ## Completed section
  6. If telegram-sender skill is available and the task warrants notification, send a Telegram update

HEARTBEAT.md Format

# Heartbeat Tasks

## Active Tasks

- Check CI status for open PRs and fix any failures
- Review and merge dependabot PRs if tests pass

## Completed

- [2026-02-17] Cleaned up stale branches

Rules

  • Empty = skip: If HEARTBEAT.md is missing, empty, or only has headers/comments, reply HEARTBEAT_OK
  • Task markers: Lines starting with - under ## Active Tasks are actionable
  • Completion: After finishing a task, move it to ## Completed with today's date prefix
  • Errors: If a task fails, leave it in Active Tasks and append (FAILED: reason) to the line
  • Safety: Never delete HEARTBEAT.md, only modify task entries
  • Scope: Tasks should be self-contained and completable within the timeout (5 minutes)

Skipable Content

These are not actionable (skip them):

  • Empty lines
  • Lines starting with # (headers)
  • Lines starting with <!-- (HTML comments)
  • Lines with only - [ ] or - [x] (empty checkboxes)
