New Feature: Rewrite Command

The /rewrite command allows users to have their messages rewritten in a clearer, more professional, or better structured form using ChatGPT AI (GPT 5 mini). The rewritten message is displayed as an ephemeral message (visible only to the user), making it perfect for getting quick writing improvements without cluttering the channel where they are.

Usage

/rewrite message:<text> [tone:<style>]

Parameters

• message (required): The message to rewrite (3-500 characters)
• tone (optional): The tone/style enum value for the rewrite. Defaults to CLEAR if not provided

Available Tones

• CLEAR (default): Make the message clear and easy to understand
• PRO: Use a professional and polished tone
• DETAILED: Expand with more detail and explanation
• TECHNICAL: Use technical and specialized language where appropriate

How It Works

1. You invoke the command with your message and optional tone
2. ChatGPT analyzes and rewrites the message according to the selected tone
3. A formatted embed displays both the original and rewritten versions
4. The response is ephemeral—only visible to you for 15 minutes
5. You can copy the rewritten text and use it.

Example

UPDATE 16 Jan 2026

• The command name has been changed into /rewrite-msg for consistency with the class in source code.
• The following is a demo that shows all possible states :

UPDATE 20 Jan 2026

• The command is back to its original name /rewrite.
• The Tone Pro has been renamed to Professionnal
• The original msg is no more provided by the bot, since it's possible to see it through a link to the command (built-in discord feat, see the demo below)
• New method added to ChatGptService API, askRaw to avoid touching existing method and for future reusabilities

Please see comments. There's a lot of final abuse that does nothing but add clutter to the code. It's best to use final when you need it.

Great stuff. Apart from what the others mentioned, im happy now 👍

[tj-wazei]

Almost there, I still really hate the usage of final, my eyes kept having to "jump" as I was reading your code.
