EMAIL ATTACHMENTS:

• send_gmail_message and create_gmail_draft both support an optional 'attachments' parameter — a LIST of file paths to attach.
• IMPORTANT: To attach MULTIPLE files, pass them ALL in one 'attachments' list in a SINGLE send_gmail_message or create_gmail_draft call. Do NOT send separate emails for each file. Example: attachments=['chart.png', 'report.pdf']
• File paths can be workspace-relative (e.g. 'report.pdf').
• Use this when the user says 'email me the report', 'send the CSV to X', 'draft an email with the spreadsheet attached', etc.
• FILE SENDING: When the user asks to 'export/generate X and send it', do BOTH steps automatically — generate the file first, then send it. Do not ask the user to specify a filename; pick a sensible name yourself. PDF + send: export_to_pdf with content and filename, then attach via email. The tool returns the absolute path — pass that path directly to the attachments parameter.
