# Casual Cron

Create Clawdbot cron jobs from natural language. Supports one-shot and repeating schedules with safe run-guard rules.

## Cron Run Guard (Hard Rules)

- When running inside a cron job: do NOT troubleshoot, do NOT restart gateway, and do NOT check time.
- Do NOT send acknowledgements or explanations.
- Output ONLY the exact message payload and then stop.

---

## How It Works

1. Agent detects scheduling intent from user message (or `/at` / `/every` command)
2. Parses: time, frequency, channel, destination, message
3. Builds `openclaw cron add` command with correct flags
4. Confirms parsed time, job name, and job id with user before executing

---

## Scheduling Rules

When a message starts with `/at` or `/every`, schedule via the CLI (NOT the cron tool API).

Use: `openclaw cron add`

### /at (one-shot)

- If user gives a clock time (e.g., "3pm"), convert to ISO with offset computed for America/New_York on that date (DST-safe).
- Prefer relative times for near-term reminders (e.g., `--at "20m"`).
- Use `--session isolated --message "Output exactly: <task>"`.
- Always include `--delete-after-run`.
- Always include `--deliver --channel <channel> --to <destination>`.

### /every (repeating)

- If interval: use `--every "<duration>"` (no timezone needed).
- If clock time: use `--cron "<expr>" --tz "America/New_York"`.
- Use `--session isolated --message "Output exactly: <task>"`.
- Always include `--deliver --channel <channel> --to <destination>`.

### Confirmation

- Always confirm parsed time, job name, and job id with the user before finalizing.

## Command Reference

One-shot (clock time, DST-aware):
```
openclaw cron add \
  --name "Reminder example" \
  --at "2026-01-28T15:00:00-05:00" \
  --session isolated \
  --message "Output exactly: <TASK>" \
  --deliver --channel telegram --to <TELEGRAM_CHAT_ID> \
  --delete-after-run
```

One-shot (relative time):
```
openclaw cron add \
  --name "Reminder in 20m" \
  --at "20m" \
  --session isolated \
  --message "Output exactly: <TASK>" \
  --deliver --channel telegram --to <TELEGRAM_CHAT_ID> \
  --delete-after-run
```

Repeating (clock time, DST-aware):
```
openclaw cron add \
  --name "Daily 3pm reminder" \
  --cron "0 15 * * *" --tz "America/New_York" \
  --session isolated \
  --message "Output exactly: <TASK>" \
  --deliver --channel telegram --to <TELEGRAM_CHAT_ID>
```

Repeating (interval):
```
openclaw cron add \
  --name "Every 2 hours" \
  --every "2h" \
  --session isolated \
  --message "Output exactly: <TASK>" \
  --deliver --channel telegram --to <TELEGRAM_CHAT_ID>
```
