Gut Analysis — Digestive health meets biometrics

Combines Suna scores (if connected) with open analytics from wearable + meal data.

Steps

Pull 30 days and run digestive analysis:

python3 << 'PYEOF'
import sys, os, json
sys.path.insert(0, os.path.join(os.environ.get('CLAUDE_PLUGIN_ROOT', '.'), 'lib'))
from fetch import fetch_biometrics
from dataclasses import asdict

                     compute_gut_score_correlations, compute_digestive_state_biometrics,
                     compute_food_hr_sensitivity, compute_glucose_variability,
                     compute_glucose_clinical, compute_postmeal_glucose)
