WhenPeak

Predict when a person's brain works best from their sleep, using the WhenPeak performance-intelligence API, and turn it into concrete scheduling advice. Use this skill whenever the user asks when to schedule a meeting, interview, exam, presentation, deep-work block, or any important task; asks about their energy, focus, alertness, productivity timing, "peak hours", post-lunch dip, or chronotype; mentions how last night's sleep will affect today; asks how to prepare for a dated event or shift their body clock for travel or an earlier start; or asks for a daily plan built around their performance curve, even if they never say the word "WhenPeak".
