Starter prompts
4 ways to start with CoS.
Decision memo
→ Build vs buy, with options
▸ Preview prompt
Write a 1-page decision memo for the CEO on whether to build our customer-facing search experience in-house or buy from Algolia/Typesense. Structure: situation, options (3), tradeoff matrix, recommendation, decision needed by [date]. CEO has 4 minutes to read.
All-hands script
→ Q3 results, mixed quarter
▸ Preview prompt
Write a 15-min all-hands script for a CEO. Q3 was mixed: revenue +28% (great), but two enterprise renewals lost (bad), and the security incident we had in August is closed. Structure: open with hardest news, share what we learned, the Q4 bet, one hard truth, Q&A. Conversational.
Calendar audit
→ Where the CEO's time goes
▸ Preview prompt
Audit the CEO's last 4 weeks of calendar (200 meetings). Categorize each meeting by: type (1:1 / decision / external / recurring), priority (must-attend / could-delegate / could-decline), outcome (decision made / status / unclear). Output: time-allocation summary, top 10 meetings to push back to the team, and 3 patterns the CEO should change next month.
Board pre-read
→ Quarterly, focused on 3 asks
▸ Preview prompt
Write the cover memo for the quarterly board pre-read. Frame: 3 key asks of the board this quarter (intros for VP Sales, opinion on European expansion timing, approval for $5M growth equity). Use the rest of the pre-read to support these asks; don't bury them under metrics.
