Daily creator pre-call briefings from your calendar

Build me an agent workflow that briefs me on every creator I'm meeting with today, before my first call.

Trigger: cron, every weekday (Monday through Friday) at 7:00am America/New_York.

Step 1. Use Google Calendar List Events on my primary calendar for today (timeMin = start of today in my local timezone, timeMax = end of today, singleEvents = true, orderBy = startTime). Pull each event's summary, description, and attendee list.

Step 2. For each event, scan the title, description, and any attendee notes for creator handles. Look for: Instagram handles like @name, TikTok handles like @name, full instagram.com/<handle> URLs, and full tiktok.com/@<handle> URLs. Tag each match with the platform it came from (Instagram or TikTok). If an event has no creator mention, skip it. Dedupe handles across events so the same creator is only researched once even if they appear in multiple meetings.

Step 3. For each unique handle, call HypeAuditor. Use Get Instagram Report for Instagram handles and Get TikTok Report for TikTok handles, passing v=2. Each report costs 1 credit, so respect the budget by only running reports for handles found in step 2. If HypeAuditor responds with 202 and a retryTtl, wait that many seconds and retry the same request. Treat 403/404 as 'creator not auditable' and note that in the briefing instead of failing the whole run.

Step 4. From each report, synthesize a pre-call briefing covering: audience authenticity score, engagement rate vs. category benchmark, audience demographics (age brackets, gender split, top countries/cities), top recent posts (with the metric that made them top), and red flags such as fake follower percentage, suspicious growth spikes, or low-confidence report state.

Step 5. For every meeting that had at least one creator, use Gmail Create a Draft to save one draft addressed to me (the workflow runner). Subject line: 'Pre-call brief: <creator handle(s)> — <meeting time> <meeting title>'. Body, in this order: meeting title and time, creator handle(s) and platform, the synthesized briefing, three tailored talking points based on the creator's niche and recent content, and one recommended ask (collab format, deliverables, or pricing range) grounded in their audience size and engagement. Keep the body skimmable — short sections, no walls of text.

Hard rules: never send an email, only save drafts. Never create calendar events or modify existing events. If today's calendar has zero creator meetings, exit quietly without creating any drafts. Log how many credits were used and how many drafts were created at the end of the run.
