Set up and run LettaBot - a multi-channel AI assistant for Telegram, Slack, Discord, WhatsApp, and Signal. Supports both interactive wizard and non-interactive (agent-friendly) configuration.
Reply with voice memos using text-to-speech. Use when the user sends a voice message, asks for an audio reply, or when a voice response would be more natural.
Post, reply, like, and repost on Bluesky using the lettabot-bluesky CLI. Read-only by default; explicit actions required.
Manage Linear issues via GraphQL API. List, filter, update, prioritize, comment, and search issues. Use when the user asks about Linear, issues, project management, or backlog.
Set up and use 1Password CLI (op). Use when installing the CLI, enabling desktop app integration, signing in (single or multi-account), or reading/injecting/running secrets via op.
Manage Apple Notes via the `memo` CLI on macOS (create, view, edit, delete, search, move, and export notes). Use when a user asks Clawdbot to add a note, list notes, search notes, or manage note folders.

Options:
-n, --name - Job name (required)-s, --schedule - Cron expression (required)-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 stateCron jobs run in one of two modes:
--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.--deliver channel:chatId): The agent's response is automatically delivered to the specified channel/chat after execution.When a cron job runs, the agent receives a message like:
[cron:cron-123abc Morning Briefing] Good morning! Review tasks for today.
Current time: 1/27/2026, 8:00:00 AM (America/Los_Angeles)
