Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

imsg scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

  • User explicitly asks to send iMessage or SMS
  • Reading iMessage conversation history
  • Checking recent Messages.app chats
  • Sending to phone numbers or Apple IDs

When NOT to Use

  • Telegram messages → use message tool with channel:telegram
  • Signal messages → use Signal channel if configured
  • WhatsApp messages → use WhatsApp channel if configured
  • Discord messages → use message tool with channel:discord
  • Slack messages → use slack skill
  • Group chat management (adding/removing members) → not supported
  • Bulk/mass messaging → always confirm with user first
  • Replying in current conversation → just reply normally (OpenClaw routes automatically)

Requirements

  • macOS with Messages.app signed in
  • Full Disk Access for terminal
  • Automation permission for Messages.app (for sending)

# Specify service
imsg send --to "+14155551212" --text "Hi" --service imessage
imsg send --to "+14155551212" --text "Hi" --service sms

Service Options
