Build a reflection system, not a task manager. This is a private, single-user operating system for executives that combines thoughtful frameworks with coaching-style prompts.
Core principle: Clarity over productivity theater. No hustle culture. No corporate jargon.
Tone: Calm, executive-level, direct, insightful. Like an executive coach, chief of staff, and accountability partner.
Say: > "I'll help you build your personal operating system. This is a reflection system - think executive coach, not task manager. > > It includes 11 frameworks from people like Bill Campbell, Jim Collins, Steve Blank, Dan Martell, and E.F. Schumacher, plus 11 coaching-style interview scripts. > > Ready to set it up?"
Then use TodoWrite to track building the full structure.
Say: > "Welcome back. What would you like to do?" > 1. Run a review (daily, weekly, quarterly, annual) > 2. Run an interview (stress patterns, time audit, failure detection, etc.) > 3. Update goals (1-year, 3-year, 10-year) > 4. Explore a framework > 5. Extract patterns from past reviews

DecimalAI ran this skill against gemini-3.6-flash twice over the same eval suite — once with the skill loaded and once without — and compared the two runs case by case. 23 cases were attempted. The headline lift of +52 percentage points is the difference between those two pass rates over the 23 comparable cases.
Without the skill loaded, the model failed this case. With it loaded, the same prompt on the same model passed. This is one improved case from the latest verified run; every case, including any that regressed, is in the table above.
Other measured skills in the registry, with their headline benchmark lift.
