cron-helper ⏰

Explain, generate, validate, and preview cron expressions β€” all from plain English or raw cron syntax.

Trigger phrases

  • "What does this cron mean: * * * * *"
  • "Explain this cron expression"
  • "Generate a cron for every weekday at 9am"
  • "When does 0 9 * * 1-5 run next?"
  • "Is this cron valid?"
  • "Convert to cron: every 15 minutes"
  • "Show me the next runs for this cron"

    • Usage

    Run the script with uv run (handles dependencies automatically):

    # Explain a cron expression
uv run scripts/cron.py explain "0 9 * * 1-5"
    Generate cron from plain English
    
uv run scripts/cron.py generate "every weekday at 9am"
uv run scripts/cron.py generate "every 15 minutes"
uv run scripts/cron.py generate "first day of month at midnight"
    Show next N run times (default 5)
    
uv run scripts/cron.py next "0 9 * * 1-5"
uv run scripts/cron.py next "*/15 * * * *" --count 10
    Validate a cron expression
    
uv run scripts/cron.py validate "0 9 * * 1-5"
uv run scripts/cron.py validate "60 9 * * *"

    Instructions for the agent

    1. Parse the user's request to determine the command: explain, generate, next, or validate. 2. Run the appropriate uv run scripts/cron.py "" command. 3. Present the output to the user, adding any clarifying context. 4. If the user provides a cron expression, always offer to explain it AND show next runs.

    Reference

    See references/cron-syntax.md for field ranges, special characters, and common examples.
