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 5d 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.

Origin

This is a copy

95% identical to imsg — 2 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

What it actually says

imsg Actions

Overview

Use imsg to read and send Messages.app iMessage/SMS on macOS.

Requirements: Messages.app signed in, Full Disk Access for your terminal, and Automation permission to control Messages.app for sending.

Inputs to collect

  • Recipient handle (phone/email) for send
  • chatId for history/watch (from imsg chats --limit 10 --json)
  • text and optional file path for sends

Actions

List chats

imsg chats --limit 10 --json

Fetch chat history

imsg history --chat-id 1 --limit 20 --attachments --json

Watch a chat

imsg watch --chat-id 1 --attachments

Send a message

imsg send --to "+14155551212" --text "hi" --file /path/pic.jpg

Notes

  • --service imessage|sms|auto controls delivery.
  • Confirm recipient + message before sending.

Ideas to try

  • Use imsg chats --limit 10 --json to discover chat ids.
  • Watch a high-signal chat to stream incoming messages.
Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
