What is add-imessage?

An add-on that connects NanoClaw to iMessage, Apple's messaging service, through a Chat SDK bridge.

Use it to install the iMessage channel, choose local or remote operation, configure access credentials, and build the project.

It adds iMessage conversations to NanoClaw, either directly on macOS or remotely through the Photon API.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00026	$0.00771
Opus 5	$0.00013	$0.00385
Sonnet 5	$0.00005	$0.00154
Haiku 4.5	$0.00003	$0.00077

Security

Grade A, and why

add-imessage 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.

Origin

This is a copy

98% identical to add-imessage — 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.

How it starts

The opening of the file, as written. The whole thing — 114 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Add iMessage Channel

Adds iMessage support via the Chat SDK bridge. Two modes: local (macOS with Full Disk Access) or remote (Photon API).

Install

NanoClaw doesn't ship channels in trunk. This skill copies the iMessage adapter in from the channels branch.

Pre-flight (idempotent)

Skip to Credentials if all of these are already in place:

src/channels/imessage.ts exists
src/channels/index.ts contains import './imessage.js';
chat-adapter-imessage is listed in package.json dependencies

Otherwise continue. Every step below is safe to re-run.

1. Fetch the channels branch

git fetch origin channels

2. Copy the adapter

git show origin/channels:src/channels/imessage.ts > src/channels/imessage.ts

3. Append the self-registration import

Append to src/channels/index.ts (skip if the line is already present):

import './imessage.js';

4. Install the adapter package (pinned)

pnpm install [email protected]

5. Build

pnpm run build

Credentials

Local Mode (macOS)

Requirements: macOS with Full Disk Access granted to the Node.js binary.

The Node binary path is buried deep (e.g. ~/.nvm/versions/node/v22.x.x/bin/node). To make it easy, open the folder in Finder so the user can drag the file into System Settings:

open "$(dirname "$(which node)")"

Then tell the user:

Open System Settings > Privacy & Security > Full Disk Access
Click +, then drag the node file from the Finder window that just opened
Toggle it on

Stop and wait for the user to confirm before continuing.

Remote Mode (Photon API)

Set up a Photon account
Get your server URL and API key

Configure environment

Local mode -- add to .env:

IMESSAGE_ENABLED=true
IMESSAGE_LOCAL=true

Remote mode -- add to .env:

IMESSAGE_LOCAL=false
IMESSAGE_SERVER_URL=https://your-photon-server.com
IMESSAGE_API_KEY=your-api-key

What ships with it

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
