Create a scheduled task running every weekday at 4pm:

1. Check tomorrow's customer meetings in @Google Calendar (exclude internal-only)
2. For each customer meeting:
   - Pull 30-day account notes and interaction history from @SharePoint / @Salesforce
   - Search 30-day public news and executive updates for that company
   - Write a 2–3 sentence background summary for each external attendee
3. Generate a 2–3 page brief per meeting, save as @Google Drive documents
4. Email me a summary via @Gmail with links to each brief

Output format: email subject "Tomorrow's Customer Meeting Briefs — [Date]",
body as a table (Client | Meeting Time | Key Topics | Brief Link)

From all opportunities, contacts, and recent activity for [Account Name] in @Salesforce:

1. Create an interactive account command center (Sites) with:
   - Pipeline overview (stage, amount, expected close date)
   - Key signals from the last 7 days (emails, meetings, support tickets)
   - Prioritized recommended next actions
2. Set a Scheduled Task: auto-refresh every weekday at 8am
3. Slack me via @Slack DM when major changes occur

Constraints: do not auto-send any external emails; amounts must match CRM source data.

Analyze @Salesforce leads from the last 30 days and cross-reference @Gmail outreach.

Find:
1. Leads with no follow-up for 48+ hours (grouped by source)
2. Broken handoff points (where response rate drops sharply)
3. Estimated pipeline loss amount

Output:
- Excel detail table (Lead ID | Source | Last Follow-up | Gap Type | Recommended Action)
- 1-page executive summary PPT highlighting seven-figure opportunity risk
- A repeatable weekly review workflow (for Scheduled Task use)

4. Post a summary of 5 bullets or fewer to @Slack #leadership

Assist with [Month] month-end budget variance analysis:
