# Smart Cron — Natural Language Cron Scheduler for OpenClaw Schedule any OpenClaw task using plain English. No cron syntax required. Just say what you want, when you want it. ## What It Does - **Natural language scheduling** — "every weekday at 9am", "every 30 minutes", "first Monday of month" - **Full cron job lifecycle** — add, list, remove, pause, resume - **Timezone-aware** — schedule in any timezone (UTC, Europe/Bucharest, etc.) - **Failure alerts** — WhatsApp/Telegram alert if a job fails - **Next run preview** — shows exactly when each job runs next - **Run logs** — persisted history of every execution - **Zero external dependencies** — uses system cron + OpenClaw orchestration ## Quick Start ```bash # Add a daily digest job smart-cron add "every weekday at 9am" --task "summarize my emails" # Add an interval job smart-cron add "every 30 minutes" --task "check server health" # Monthly job smart-cron add "first Monday of month at 10am" --task "generate monthly report" # List all scheduled jobs smart-cron list # Show next run times smart-cron next # View job logs smart-cron logs # Pause a job (without deleting it) smart-cron pause <job-id> # Resume paused job smart-cron resume <job-id> # Remove a job smart-cron remove <job-id> ``` ## Commands | Command | Description | |---------|-------------| | `smart-cron add <schedule> --task <task>` | Schedule a new task | | `smart-cron list` | List all jobs with status | | `smart-cron remove <id>` | Remove a job | | `smart-cron next` | Show next run time for all jobs | | `smart-cron run <id>` | Run a job immediately | | `smart-cron logs [id]` | View execution logs | | `smart-cron pause <id>` | Pause a job | | `smart-cron resume <id>` | Resume a paused job | ## Supported Schedule Expressions ### Intervals - `every 5 minutes` → `*/5 * * * *` - `every hour` → `0 * * * *` - `every 2 hours` → `0 */2 * * *` - `every 30 minutes` → `*/30 * * * *` ### Daily - `every day at 9am` → `0 9 * * *` - `every weekday at 9am` → `0 9 * * 1-5` - `every weekend at noon` → `0 12 * * 6,0` - `daily at midnight` → `0 0 * * *` ### Weekly - `every Monday at 8am` → `0 8 * * 1` - `every Friday at 5pm` → `0 17 * * 5` ### Monthly - `first Monday of month` → calculated and re-scheduled - `1st of month at 9am` → `0 9 1 * *` - `last day of month` → calculated dynamically ### Custom cron (passthrough) - `0 */6 * * *` → runs as-is for advanced users ## Timezone Support ```bash # Schedule in your local timezone smart-cron add "every weekday at 9am" \ --task "daily standup reminder" \ --timezone Europe/Bucharest # List shows times in both UTC and local tz ``` ## Failure Alerts When a scheduled task fails, Smart Cron sends an alert via your configured channel: ``` ⚠️ Smart Cron: "daily standup reminder" FAILED Time: 09:00 EET (07:00 UTC) Error: Task timed out after 300s Last success: yesterday at 09:00 Logs: smart-cron logs job-123 ``` ## Data Storage All job configs and logs stored locally at `~/.openclaw/workspace/smart-cron-data/`. SQLite, no telemetry. ## Configuration Edit `~/.openclaw/workspace/smart-cron-data/config.json`: ```json { "default_timezone": "Europe/Bucharest", "alert_channel": "whatsapp", "alert_on_failure": true, "log_retention_days": 30 } ``` ## Use Cases ### Morning Briefing ```bash smart-cron add "every weekday at 8am" --task "summarize overnight emails and news" ``` ### Uptime Monitoring ```bash smart-cron add "every 5 minutes" --task "check all APIs and alert if any is down" ``` ### Weekly Reports ```bash smart-cron add "every Friday at 5pm" --task "generate weekly work summary and log to MEMORY.md" ``` ### Monthly Cleanup ```bash smart-cron add "1st of month at 2am" --task "clean old logs and archive memory files older than 90 days" ``` ## Requirements - OpenClaw 1.0+ - Python 3.8+ (for schedule parsing) - cron daemon (standard on Linux/macOS) ## Source & Issues - **Source:** https://github.com/mariusfit/smart-cron - **Issues:** https://github.com/mariusfit/smart-cron/issues - **Author:** [@mariusfit](https://github.com/mariusfit)
