- `-d, --deliver` - Where to send response (format: `channel:chatId`). **Defaults to last messaged chat.**
- `--disabled` - Create disabled
- `-m, --message` - Prompt sent to the agent when the job fires (required)
- `-d, --deliver` - Auto-deliver the agent's response to a channel (format: `channel:chatId`). Without this flag, the job runs in **silent mode** (see below).
- `--disabled` - Create in disabled state
## Silent Mode vs Delivery Mode
Cron jobs run in one of two modes:
- **Silent mode** (no `--deliver`): The agent receives the message and can act on it (e.g., update memory, run tools), but the response is NOT automatically sent to any chat. If the agent wants to send a message, it must explicitly use `lettabot-message send`.
- **Delivery mode** (`--deliver channel:chatId`): The agent's response is automatically delivered to the specified channel/chat after execution.
## Message Format
When a cron job runs, you receive a message like:
When a cron job runs, the agent receives a message like:

## Notes
- Jobs schedule immediately when created (no restart needed)
- Use `lettabot-cron list` to see next run times and last run status
- Jobs persist in `cron-jobs.json`
- Logs written to `cron-log.jsonl`
- Without `--deliver`, the agent must use `lettabot-message send` to communicate results to users
