using-imessage-max

using-imessage-max is a skill for Claude Code, Codex from cyberpapiii/imessage-max. It costs 83 tokens per session (1,442 once invoked), scanned A, original, MIT.

Instructions for using an iMessage Max server, a tool that lets an agent inspect and send iMessage conversations. They explain how to find chats, review messages, browse shared items, and choose the right conversation.

In plain words
What is it for?
Catching up on recent or unread conversations, inspecting a known chat, finding active discussions, viewing shared items, and sending messages to the correct thread.
Why use it?
They reduce the risk of missing relevant messages or sending a reply to the wrong thread.

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

using-imessage-max 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 yesterday.

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.

Using iMessage Max

Overview

Use this skill to choose the right iMessage Max tool sequence for the user's intent.

Start broad when completeness matters, then narrow. Unread-only and activity-only views miss things. Do not let either stand in for a full recent overview unless the user asked for that narrower slice.

When reporting results back to the user, use human chat names and participant names. Treat chat_id values such as chat123 as internal handles for follow-up tool calls and exact sends; do not refer to conversations as "Chat 123" in user-facing prose when chat.name, name, or participant labels are available.

Workflow guide

Broad catch-up or daily sweep

Use this when the user says things like:

  • "catch me up on everything I missed"
  • "morning sweep"
  • "what happened in the last day or two"
  • "show me what I should know from my texts"

Default flow:

  1. Start with list_chats using a recent window such as since="1d" or since="2d" and sort="recent".
  2. Use get_unread as a cross-check for still-unread threads and message-level unread review when needed.
  3. Use get_active_conversations only to prioritize which recent threads may deserve attention first.
  4. Use get_messages to drill into the chats surfaced by the overview. If you already hold a next_rowid from a previous turn, call get_messages_since with it instead of get_unread.

Why:

  • list_chats gives the safest broad preview across recent conversations.
  • get_unread is narrower and can miss important chats that were already opened.
  • get_active_conversations is also narrower and can miss quiet but important threads.
  • list_chats, search, get_unread, and find_chat hide junk and unknown-sender chats by default and report how many in filtered_hidden. Only pass include_filtered=true when the user asks about a message that did not show up.

Targeted lookup

Use this when the user already knows the person, thread, or topic.

  • If they know the person or chat identity, start with find_chat.
  • If they already know the exact thread, use get_chat_details before opening message history.
  • If they know the topic but not the chat, start with search.
  • Then use get_messages or get_context to read the relevant section in detail.

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.
