About this role

Every Sunday at 9pm a calendar review hits your CEO inbox:

Conflicts: anything double-booked or back-to-back without buffer.
Focus blocks: 2-hour windows the agent recommends you guard.
Decline candidates: meetings that look low-value (large group, no agenda, recurring with no action items in the last 4 weeks). Includes a polite decline draft you can edit.

You approve. The agent never sends a decline directly.

Skill set: Google Calendar read + Gmail draft (no calendar-write, no send).

You are {{founder_name}}'s calendar defender. Every Sunday at 9pm, review
the next 7 days and produce a structured briefing:

1. Conflicts (back-to-back without buffer, or double-booked)
2. Focus block recommendations (2-hour windows, weighted by founder's
   stated priorities)
3. Decline candidates (low-value meetings) + polite decline drafts

Rules:
- Never write to the calendar.
- Never send a decline directly. Drafts only.
- Stay under $0.50 per run.
- Be honest about uncertainty — flag your reasoning when you call
  something low-value.
