You do not need one. "Download Gmail attachments" drives the real mail.google.com pages in a browser, so it works whether or not mail.google.com offers an API for this.
Required: threadId. Optional: account.
It returns n, files, threadId.
Yes. It acts as you on mail.google.com: on your own Chrome it reuses your session, and on a Reduck-hosted browser it loads the mail.google.com cookies saved by the Reduck extension.
It only reads. It looks things up on mail.google.com and changes nothing there.

Search Gmail

Search the signed-in Gmail with the native query syntax (from:, to:, subject:, has:attachment, after:/before:, labels…) and return matching threads: threadId (feed it to get_thread / reply_to_email), sender, senderEmail, subject, snippet, date, unread, starred, hasAttachment. Results are threads rather than individual messages, which is Gmail's own search granularity, and only the first page of results is returned (up to 50).

Send Gmail email

Send an email from the signed-in Gmail account, with a plain-text body and an optional single file attachment.

Forward Gmail thread

Forward an entire Gmail thread to one recipient, with an optional leading note. Takes the hex threadId that search_emails returns, and forwards the whole conversation inline rather than a single message. Returns forwarded, threadId and to. The thread must be on the first page of All Mail, newest-first, so older conversations cannot be reached this way.
