What this skill does
gmail +reply PREREQUISITE: Read ../gws-shared/SKILL.md for auth, global flags, and security rules. If missing, run gws generate-skills to create it. Reply to a message (handles threading automatically) Usage Flags Flag Required Default Description ------ ---------- --------- ------------- --message-id ✓ — Gmail message ID to reply to --body ✓ — Reply body (plain text, or HTML with --html) --from — — Sender address (for send-as/alias; omit to use account default) --to — — Additional To email address(es), comma-separated --attach — — Attach a file (can be specified multiple times) --cc — — CC email address(es), comma-separated --bcc — — BCC email address(es), comma-separated --html — — Treat --body as HTML content (default is plain text) --dry-run — — Show the request that would be sent without executing it --draft — — Save as draft instead of sending Examples 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 gmailquote 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.
