What is gws-gmail-reply?
gws-gmail-reply is a specialized tool within the Openclaw Skills ecosystem designed to streamline email communication through the Google Workspace CLI. This skill simplifies the process of responding to existing email threads by automatically managing complex headers like In-Reply-To, References, and threadId. It provides developers with a robust interface to send automated or manual responses directly from terminal environments or integrated scripts.
By leveraging this skill, users can ensure their replies are perfectly integrated into existing conversations while maintaining professional formatting. Whether you are building automated notification systems or managing a high volume of communication, this component of Openclaw Skills offers the flexibility of plain text or HTML bodies, draft creation, and file attachment handling.
gws-gmail-reply Use Cases
- Automating customer support or ticketing responses based on specific message IDs.
- Sending rapid follow-up emails with file attachments directly from a development environment.
- Integrating email response capabilities into CI/CD pipelines or server monitoring scripts.
- Creating draft replies as part of a multi-step AI-driven workflow for manual review.
- Managing high-volume transactional email replies without using the Gmail web interface.
How gws-gmail-reply Works
- The user initiates the skill by providing a target Gmail message ID and the desired body content.
- The skill analyzes the target message to retrieve threading metadata, ensuring the reply is correctly nested within the conversation.
- The skill processes optional flags such as --cc, --bcc, or --to to expand the recipient list.
- If the --html flag is present, the skill formats the body as an HTML fragment, preserving quoting styles and inline references.
- If attachments are provided, they are encoded and bundled into the multi-part MIME message.
- The final request is either dispatched immediately via the Gmail API or saved to the user's Drafts folder.
gws-gmail-reply Setup
