Write a Gmail draft

A draft is the finished article sitting where a person can read it, change it and send it themselves. Everything in this skill writes to the Drafts folder and stops there. Nothing here sends, and nothing here can: the send path is a separate operation with its own gate, and it lives in gmail-send.

Most of what goes wrong is quiet, and all of it is visible in the preview the tools hand back — if you show it. A reply-all that keeps the user's own address, so they answer themselves. A reply that goes to the From address when the sender asked for answers somewhere else. A forward whose original is quoted as text, so the words survive and the original's attachments do not — say which, rather than letting the user assume both. A body written in Markdown or HTML, which arrives as literal asterisks and angle brackets because the HTML part is generated from your plain text and markup in that text is written out, not rendered.
