Analyze and Optimize Health Goals

Analyzes personal health-goal data across eight functions: SMART goal validation (scoring Specific/Measurable/Achievable/Relevant/Time-bound each 1-5, with concrete achievability guardrails like 0.5-1kg/week for weight loss or 3-5 sessions/week for exercise, producing an overall letter-grade score); progress tracking (completion percentage versus elapsed time, velocity analysis, and a four-tier rating from ahead-of-schedule to severely-behind); habit-formation analysis (current and longest streaks, completion-rate breakdowns by week and weekday, a habit-strength score, and a five-stage model from a 1-7 day launch period through a 67-plus day automatic stage); motivation assessment (a 1-10 tracked score, intrinsic/extrinsic/social-support factors, and stage-specific dip warnings at weeks 2-3, months 1-2, and past month 3); an achievement system (unlockable badges for milestones like a 7/21/30/66-day streak or 50%/100% goal completion); obstacle identification across five categories - time, motivation, environment, ability, physical - each paired with concrete mitigation suggestions; cross-metric correlation analysis (Pearson correlation and regression between a goal like weight loss and nutrition intake, exercise frequency, or sleep duration, with a worked example showing calorie intake at -0.75 correlation and exercise frequency at +0.68); and an interactive HTML report generator built on ECharts (progress line charts with milestone markers, a calendar habit heatmap, a multi-goal completion donut chart, and a motivation trend chart, fully offline and theme-switchable).

Use it to evaluate whether a health goal meets SMART criteria, track its progress against nutrition, exercise, or sleep data, or get personalized adjustment and risk guidance. It draws an explicit medical safety boundary: it can help set goals, track progress, identify behavioral patterns, and generate visual reports, but it does not diagnose, prescribe treatment, replace professional medical advice, or handle eating disorders or compulsive behavior. It watches for specific danger signals and recommends referral when they appear: a weight-loss target over 1kg/week, a weight-gain target over 0.5kg/week, extreme calorie restriction under 1200 kcal/day, over 2 hours of exercise daily for 7 days a week, a completion rate under 30% for 3 consecutive weeks, a motivation score under 3 for 2 consecutive weeks, or reports of physical discomfort or compulsive patterns - directing users to a doctor, specialist, dietitian, or fitness coach as appropriate.

Inputs are a main goal-tracking JSON file plus dated daily log files, and optionally correlated data sources for nutrition, exercise, and sleep. Output is a structured Markdown analysis report - goal overview, SMART star ratings, progress percentage with a trend-based completion-date forecast, habit streak and stage, motivation score, ranked correlation factors with recommendations, identified obstacles with solutions, newly unlocked achievements, and next-step actions - plus, on request, a self-contained interactive HTML report built on the ECharts 5.x CDN with light/dark themes and PDF export.

Generates its visualizations with ECharts 5.x loaded from a CDN, and its correlation analysis is designed to read from sibling nutrition-tracker and fitness-tracker data files so goal progress can be explained by real intake, exercise, and sleep numbers rather than analyzed in isolation.

Individuals or coaches managing personal health goals - weight, exercise, sleep, or habit formation - who want SMART-goal validation, progress and motivation tracking, and cross-metric correlation insight, with built-in guardrails that route genuinely risky patterns to a medical professional instead of offering diagnosis.
