The prompt
One session with a coding agent and your version runs.
Build me a cron-job monitor like Cronitor / Healthchecks. Requirements:
- Each monitored job gets a unique ping URL (/ping/:uuid). The job's crontab
line just appends `&& curl -fsS <url>` · document this.
- Define jobs in SQLite via a basic-auth /admin page: name, expected period
(e.g. every 60 min) and grace time. Store every ping with timestamp.
- A scheduler loop checks each job: if now > last_ping + period + grace, the job
is LATE → send one alert webhook (Discord/Slack/Telegram, URL in .env) with
the job name and how late it is. Alert again on recovery. No alert spam ·
one per state change.
- /admin dashboard: each job as a row with green/amber/red status dot, last ping
time ("7 min ago"), and a 24h ping histogram as inline SVG.
- Support /ping/:uuid/fail for explicit failure reports with an optional body
shown in the alert.
- Python or Node, single process, systemd unit included.Curated prompt: written and reviewed by hand for this app. In English on purpose — it is the language coding agents work best in.
What you lose
- their status pages and team features
- alert routing (SMS, PagerDuty)
- cron expression insights
