At a glance
Checks that iMessage can be read on a Mac, shows the access policy and sender allowlist, and helps you decide who may text your assistant.
- Works in 3 steps: Full Disk Access — run ls… → Access — read… → What next — end with a concrete next…
- Setting up the iMessage channel for the first time
- SKILL.md covers Status and guidance, Build the allowlist — don't pair and Implementation notes
- Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md
What it does
No token is needed here, because iMessage is read straight from `~/Library/Messages/chat.db`. The skill runs `ls` on that file to test whether Full Disk Access has been granted to your terminal or IDE, and when the command fails with Operation not permitted it explains where to enable access under Privacy & Security in System Settings. It then reads `~/.claude/channels/imessage/access.json` and summarizes the DM policy, allowed senders and any pending pairings.
Its advice is to build an allowlist rather than use pairing, since pairing sends an automatic reply code to every contact who texts the Mac. Texting yourself always works, others are added by phone number or email with `/imessage:access allow`, and a current `pairing` policy is flagged with an offer to switch back to `allowlist`. The skill only shows status, and any arguments passed to it are unused.
When your agent uses it
- Setting up the iMessage channel for the first time
- Finding out why texts are not reaching the assistant
- Reviewing who is allowed to message you through iMessage
Example prompts
- “Check my iMessage setup and tell me what is missing.”
- “Why aren't my texts reaching the assistant?”
- “Allow my partner's number through iMessage and keep everyone else blocked.”
Requirements
- Full Disk Access granted to your terminal or IDE
- A Mac with the Messages database at `~/Library/Messages/chat.db`
- Pre-approved tools (allowed-tools): Read, Bash(ls *)
Workflow steps
3 steps, taken from the first numbered list in SKILL.md.
- Full Disk Access — run ls ~/Library/Messages/chat.db. If it fails
- Access — read ~/.claude/channels/imessage/access.json (missing file
- What next — end with a concrete next step based on state
What it can do on your machine
Read from SKILL.md and the folder at commit 315c4e4. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves these tools, so the agent can use them without asking each time:
ReadBash(ls *)
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
iMessage Channel Setup loads about 877 tokens when it runs. Until then it costs about 55 tokens; SKILL.md has 448 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check: notes
The automated check noted patterns worth knowing about, such as sudo or a known installer.
- NoteMentions a .env fileSKILL.md:78
- No `.env` file for this channel. No token. The only OS-level setup is FDA
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

/imessage:configure — iMessage Channel Setup
There's no token to save — iMessage reads ~/Library/Messages/chat.db
directly. This skill checks whether that works and orients the user on
access policy.
Arguments passed: $ARGUMENTS (unused — this skill only shows status)
Status and guidance
Read state and give the user a complete picture:
Full Disk Access — run
ls ~/Library/Messages/chat.db. If it fails with "Operation not permitted", FDA isn't granted. Say: "Grant Full Disk Access to your terminal (or IDE if that's where Claude Code runs): System Settings → Privacy & Security → Full Disk Access. The server can't read chat.db without it."Access — read
~/.claude/channels/imessage/access.json(missing file = defaults:dmPolicy: "allowlist", empty allowlist). Show:- DM policy and what it means in one line
- Allowed senders: count, and list the handles
- Pending pairings: count, with codes if any (only if policy is
pairing)
What next — end with a concrete next step based on state:
- FDA not granted → the FDA instructions above
- FDA granted, policy is allowlist → "Text yourself from any device
signed into your Apple ID — self-chat always bypasses the gate. To let
someone else through:
/imessage:access allow +15551234567." - FDA granted, someone allowed → "Ready. Self-chat works; {N} other sender(s) allowed."
Build the allowlist — don't pair
iMessage reads your personal chat.db. You already know the phone
numbers and emails of people you'd allow — there's no ID-capture problem to
solve. Pairing has no upside here and a clear downside: every contact who
texts this Mac gets an unsolicited auto-reply.
Drive the conversation this way:
- Read the allowlist. Tell the user who's in it (self-chat always works regardless).
- Ask: "Besides yourself, who should be able to text you through this?"
- "Nobody, just me" → done. The default
allowlistwith an empty list is correct. Self-chat bypasses the gate. - "My partner / a friend / a couple people" → ask for each handle
(phone like
+15551234567or email likethem@icloud.com) and offer to run/imessage:access allow <handle>for each. Stay onallowlist. - Current policy is
pairing→ flag it immediately: "Your policy ispairing, which auto-replies a code to every contact who texts this Mac. Switch back toallowlist?" and offer/imessage:access policy allowlist. Don't wait to be asked. - User asks for
pairing→ push back. Explain the auto-reply-to- everyone consequence. If they insist and confirm a dedicated line with few contacts, fine — but treat it as a one-off, not a recommendation.

Handles are +15551234567 or someone@icloud.com. disabled drops

Implementation notes
- No
