Translates cron expressions into human-readable explanations.

What this skill does

• Parses standard cron syntax (5 fields)
• Explains in English or French
• Validates cron before deployment
• Example: 0 9 * * 1-5 → 'At 09:00, Monday through Friday'

When to use this skill

• ✅ Document cron jobs
• ✅ Validate cron before deployment
