Message your Dot from Raycast

Set up a Raycast command on my Mac that sends quick messages to my existing ChatGPT dot.

Desired flow:
⌘Space → dot → Tab → message → Enter.
Send in the background without taking focus or changing what I’m working on.

Implement and install it—not just instructions.

1. Discover my dot’s exact conversation URL and the browser where I’m signed in. Support a regular browser tab; an installed browser web app is optional. Ask only for details you can’t discover.

2. Create a small, executable Raycast Script Command with compact feedback, one text argument, and alias “dot”. For Brave/Chrome, JXA (`#!/usr/bin/osascript -l JavaScript`) can use the browser’s scripting interface.

3. Reuse the exact dot tab if open. Otherwise, open the conversation in a background tab or hidden window without changing my active tab or taking focus. If I use an installed web app, `open -g -j` is an option. Verify the chosen method works with my browser.

4. Wait with a timeout for the composer. Inspect current page markup; previously working selectors were:
   Composer: [role="textbox"][aria-label="Message"][contenteditable="true"]
   Send: button[aria-label="Send"]
   For that contenteditable composer, focus it and use document.execCommand('insertText', false, message), then click Send when enabled. Pass message text using JSON serialization and preserve existing drafts.

5. Explain and obtain approval for required permissions, such as “Allow JavaScript from Apple Events” and macOS Raycast→browser Automation. Verify they actually work.

6. Register the script directory and alias in Raycast.

Test by actually sending harmless messages THROUGH RAYCAST. Test both an existing conversation tab and reopening it after closing the tab/window. Verify the dot replies and focus is preserved. Fix failures before declaring success, and clearly report any untested cases. Keep the implementation small.
