Phy Cron Explainer

Agent skill
1 skill

Cron expression explainer, validator, and converter. Translates any cron expression into plain English ("0 /6 " → "Every 6 hours, at minute 0"), shows the next 5 scheduled run times with exact dates, detects impossible/conflicting expressions (Feb 30, conflicting day-of-week + day-of-month), identifies suspicious patterns (every minute in production, very-frequent schedules on expensive operations), and converts plain English descriptions to cron ("every weekday at 9am" → "0 9 1-5"). Supports all major flavors: standard Unix 5-field, 6-field with seconds, AWS EventBridge, GitHub Actions schedule, Kubernetes CronJob, Spring @Scheduled, and special strings (@yearly, @monthly, @daily, @hourly, @reboot). Also scans .github/workflows/ and Kubernetes YAML files for cron schedules and audits them. Zero external API — pure local parsing. Triggers on "cron expression", "what does this cron mean", "cron to English", "cron schedule", "explain cron", "@reboot", "/cron".
