What it does

This skill teaches an AI agent how to set up recurring background jobs for the GBrain knowledge system. It checks that new jobs do not collide on a 5-minute time slot, holds their output during quiet hours (11 PM to 8 AM by default) unless the user is awake, and registers them with a host scheduler such as crontab or Railway cron. It also covers making jobs safe to re-run and calling GBrain through a wrapper command.

Great for

  • Developers running GBrain on a server who want scheduled syncs and maintenance jobs
  • Operators managing multi-source GBrain brains who need consolidated cron lines
  • Anyone who wants scheduled jobs that respect quiet hours

Skip it if

  • People who have never run a cron job or do not have GBrain installed, since the instructions assume it (the skill is not useful on its own)
  • Setups where the crontab or database is edited without review, because a wrong entry can silently find an empty database or run duplicate work
  • Users who do not want the agent to modify scheduler configuration, since the skill is marked mutating and writes to pages and reports

Try asking

  • “Schedule a job that syncs all my GBrain sources every 5 minutes”
  • “What jobs are running right now?”
  • “Set up a nightly report job and check that it does not collide with existing jobs”
  • “Add a cron entry that respects my quiet hours”

  3. 3

    Ask for the task

    No special command needed — the agent reads the skill's description and loads it when your request matches. Try one of the prompts above.

Get better results

  • Test every new cron job on 3-5 items first, as the skill's convention requires
  • Run gbrain doctor after setup to catch crontab lines that bypass the gbrain-run wrapper
  • Check the managed or classic brain mode before installing a sync line, since managed brains need different flags
