Gmail: Reply to a message (handles threading automatically).
— the description by Google Workspace

AutoGineer summary

Written by AutoGineer from the skill’s own files, not by the author

The gws-gmail-reply skill provides a command-line interface to send replies to existing Gmail messages. It simplifies the process of managing email threads by automatically handling In-Reply-To, References, and threadId headers. The tool supports both plain text and HTML bodies, allows for adding CC/BCC recipients, and enables file attachments. It also includes safety features like a dry-run mode and the ability to save replies as drafts instead of sending them immediately.

What it does

  • Sends replies to specific Gmail messages using a message ID.
  • Automatically manages email threading headers.
  • Supports plain text and HTML email content.
  • Allows adding CC, BCC, and additional To recipients.
  • Enables attaching multiple files to a reply.
  • Provides a draft mode to save messages for later review.

When to use it

  • When you need to automate email responses within a terminal workflow.
  • When you want to programmatically send follow-up emails while maintaining thread context.
  • When you need to attach files to automated email replies.
  • When you prefer to draft automated responses before sending them.

Advantages

  • Maintains proper email threading without manual header configuration.
  • Flexible support for both plain text and HTML formatting.
  • Includes a dry-run feature to verify requests before execution.
  • Supports standard email features like CC, BCC, and attachments.

Usage examples

“Reply to message 18f1a2b3c4d with the text 'Thanks, got it!'”
The agent sends a reply to the specified message ID with the provided text.
“Reply to message 18f1a2b3c4d and CC [email removed] with the message 'Looping in Carol'”
The agent sends a threaded reply to the message, including Carol in the CC field.
“Save a reply to message 18f1a2b3c4d as a draft with the body 'Draft reply'”
The agent creates a draft in the user's Gmail account instead of sending the email.
“Reply to message 18f1a2b3c4d with an HTML body containing bold text”
The agent sends an HTML-formatted reply to the specified message.

gws gmail +reply --message-id 18f1a2b3c4d --body 'Adding Dave' --to [email protected]

Tips

  • Automatically sets In-Reply-To, References, and threadId headers.

  • Quotes the original message in the reply body.

  • --to adds extra recipients to the To field.

  • Use -a/--attach to add file attachments. Can be specified multiple times.

  • With --html, the quoted block uses Gmail's gmail_quote CSS classes and preserves HTML formatting. Use fragment tags (<p>, <b>, <a>, etc.) — no <html>/<body> wrapper needed.

  • With --html, inline images in the quoted message are preserved via cid: references.

  • Use --draft to save the reply as a draft instead of sending it immediately.

  • For reply-all, use +reply-all instead.
