Tip only: iMessage → Shortcuts → webhook

A Mac already sees iMessage. The bot needs a POST, not a new plugin.

What hurt

James Martinez published a Shortcuts recipe: always-on Mac, Shortcuts Automation on Message, pick contacts, leave Message Contains blank, run immediately, notify off. Sender and content become variables, then Get Contents of URL as POST with Bearer token and a JSON body of sender + text. Mac stays awake and signed into Messages.

What to install or create

Grok Bot routine with webhook trigger. Shortcuts POSTs sender + text. Bot monitors or drafts. You still send any reply. Tip only — no prompt.

Bots

  • Message desk

    Reads webhook POSTs from Shortcuts. Drafts or logs. You send.

Plugins

  • None on day one. Follow the first-run steps.

Files

  • The cited tweet is the recipe. Optional: a contact allow-list.

Routines

  • Webhook trigger. Shortcuts Message automation POSTs here. Mac stays awake.

The prompt

This is a tip, not a pasteable system prompt. The author did not publish one. Follow the first-run steps.

First run

  1. 1Read the cited tweet. Follow that Shortcuts path, do not invent a new one.
  2. 2Create a Grok Bot routine, add trigger, select webhook. Copy URL and token.
  3. 3On an always-on Mac: Shortcuts → Automation → Message. Pick contacts. Leave Message Contains blank.
  4. 4Run Immediately, Notify When Run off. Map sender and content variables. GET Contents of URL, POST, Bearer header, JSON body sender + text. Insert variables via right-click, do not type them.
  5. 5Keep the Mac awake and signed into Messages. First real message: bot drafts, you send.

Approval fence

Do not send, forward, or delete iMessages without your yes.

What to tweak

Steal the Shortcuts POST. Keep the Mac awake. Do not auto-reply.
