Draft a follow-up email after every tl;dv meeting

Build me an agent workflow that drafts a polished follow-up email in Gmail every time tl;dv finishes generating a meeting transcript.

Trigger: poll tl;dv for the new_transcript event. The trigger payload will include the meeting id.

Integrations the agent should use: tl;dv (Get Meeting, Get Meeting Notes, Get Meeting Transcript) and Gmail (Create a Draft).

On each run the agent should:

1. Call tl;dv Get Meeting using the meeting id from the trigger to fetch metadata: organizer, invitees (with email + domain), title, start time, and whether it is part of a recurring series.

2. Determine internal vs external attendees by comparing each invitee's email domain to the organizer's domain. Anyone on a different domain is external. If there are zero external attendees, OR the meeting is part of a recurring internal-only series, the agent should skip drafting and exit cleanly with a short log line explaining why.

3. Call tl;dv Get Meeting Notes to retrieve the structured AI summary (topics + markdown summary). Use this as the backbone of the recap.

4. Call tl;dv Get Meeting Transcript to pull the full time-stamped transcript. Use this only to extract one or two short verbatim quotes when something specific needs reinforcing (a commitment, a number, a decision). Do not paste large chunks of transcript into the email.

5. Compose a concise recap email in my voice. Structure: a one-line thank-you, three or four key decisions as bullets, action items grouped by owner with a target date when one was mentioned, and a clear proposed next step or follow-up meeting. Keep it under ~250 words. No marketing fluff, no em dashes.

6. Call Gmail Create a Draft. To: every external attendee. Cc: the meeting organizer (and any internal attendees who were active speakers, if easy to detect from the transcript). Subject line: "Recap: <meeting title>" or similar. Body: the recap from step 5, plain text or lightweight HTML.

Hard rules: ALWAYS create a draft, NEVER send. Never include internal-only meetings. If any tl;dv call fails or the transcript is empty, exit gracefully without creating a half-baked draft.

During setup, ask me for a short writing-style sample (a recap I have sent before, or a few sentences describing my tone) and bake that into the agent's instructions so every draft sounds like me.
