Nutrition and Hydration

Minimum evidence

Read profile, health constraints, event or workout duration and intensity, weather, elevation, carrying capacity, prior intake, tolerance, and rehearsals. Retrieve the relevant activity when reviewing execution.

Use get_events for the planned effort, get_activity or get_strava_activity for completed execution, and get_weather with profile coordinates when conditions matter. Use streams only for a defined analysis.

Knowledge

Read knowledge/nutrition.md and environmental guidance when conditions matter. Distinguish research-supported ranges from coaching heuristics and product labels.

Analysis

Calculate carbohydrates, fluid, sodium, caffeine, and calories in consistent units. Compare hourly intake with duration, conditions, athlete history, and what was practiced. Do not prescribe a universal target, infer sweat rate without measurement, or recommend medication. Apply health triage to confusion, rapid weight change, persistent vomiting, or other warning signs.

Output

Offer a starting range, operational plan, alternatives, and rehearsal or monitoring method. State assumptions and missing evidence. Save only accepted, athlete-specific tolerances and outcomes, not provisional explanations.
