This does exactly what you'd expect: grabs a Gmail message by ID and extracts the body text or headers. It automatically converts HTML-only emails to plain text and handles multipart messages and base64 decoding behind the scenes. You'll reach for this when building email processing workflows or debugging message content issues. The JSON output mode makes it easy to pipe into other tools. One nice touch is the dry-run flag so you can see the actual API request before hitting Gmail's servers.
