strava-injury-risk-triage

Goal

Estimate short-term injury/fatigue risk based on week-over-week changes and activity mix.

Procedure

1. •Call weekly_stats(weeks=4, week_start=monday, tz_name=Asia/Tokyo) to get last 4 weeks.
2. •Compute heuristics (no medical claims):
   • •Load ramp: this_week_distance / avg_last_3_weeks_distance
   • •Long-session flag: any week with moving_time > 6h
   • •Climb spike: this_week_elev / avg_last_3_weeks_elev
   • •Sport imbalance: if one sport_type > 80% of volume
3. •Classify risk: low|medium|high with reasons.
4. •Provide 2-3 safe suggestions (sleep, easy Z2, rest day, mobility). Avoid diagnosis.

Output format (JSON)

• •risk_level: low|medium|high
• •signals: {ramp_ratio, climb_ratio, imbalance, long_session_flag}
• •reasons: [strings]
• •suggestions: [strings]
