Running an AI Agent on a Schedule with a Cron Job

Agents become real automation when they run on a schedule. A daily cron that calls your Claude-powered route is the simplest 'background worker' you'll ever write.

Some examples

• Vercel Cron hits /api/digest every morning at 8am and Claude summarizes yesterday's GitHub activity.
• A GitHub Action runs a triage agent on new issues every hour.
• A serverless function on a 5-minute cron checks for new mentions and drafts replies for review.
• A nightly job calls an agent that updates a status doc with what shipped that day.

Try it!

Add a cron entry in vercel.json pointing at a Claude-powered route. Have it write to a file or send a message daily.

Practice this safely

Try this with a school, hobby, or family example where the stakes are low. Use the AI output as a draft you can question, not as the final answer.

1. 1Ask AI to explain cron in plain language, then underline anything that sounds uncertain or too broad.
2. 2Give it one detail from "Running an AI Agent on a Schedule with a Cron Job" and ask for two possible next steps plus one reason each step might be wrong.
3. 3Check scheduling against a trusted source, teacher, adult, expert, or original document before you use it.
