Biometric Intelligence Skill

This skill enables energy-aware decision making using Oura ring biometric data.

Key Metrics from Oura

Readiness Score (0-100)

  • 85+: Peak performance day - tackle hard problems
  • 70-84: Normal productivity - regular work
  • 60-69: Low energy - focus on maintenance tasks
  • <60: Recovery needed - minimal cognitive load

Sleep Score (0-100)

  • 85+: Well-rested - complex tasks OK
  • 70-84: Adequate - normal work capacity
  • <70: Sleep debt - prioritize rest, avoid decisions

HRV (Heart Rate Variability)

  • Above baseline: Good recovery, stress tolerance high
  • Below baseline: Accumulated stress, need recovery
  • Trending down: Approaching burnout, reduce load

Activity Balance

  • Met goal: Good energy expenditure
  • Under goal: May have excess energy, physical activity helps
  • Way over: Rest needed, avoid stacking stress

Energy-Aware Scheduling Principles

High Readiness Days (85+)

  • Schedule deep work sessions
  • Tackle creative or complex problems
  • Make important decisions
  • Push on challenging goals
  • Social/networking activities

Medium Readiness Days (70-84)

  • Regular task execution
  • Meetings and collaboration
  • Administrative work
  • Learning and skill building
  • Moderate exercise

Low Readiness Days (<70)

  • Quick wins and easy tasks
  • Reading and passive learning
  • Planning (not executing)
  • Gentle movement only
  • Social media/content consumption

Hunter Brain + Biometrics Patterns

When HRV is Low

  • Resistance will be HIGH
  • Don't fight it - log and redirect
  • Use body doubling or external accountability
  • Break tasks into 10-minute chunks

When Sleep Score is Low

  • Dopamine regulation is impaired
  • Hyperfocus risk (on wrong things)
  • Set hard time boundaries
  • Avoid starting new projects

Recovery Recommendations

Based on Oura data, recommend:

  1. Physical: Light walk, stretching, nap
  2. Mental: No new decisions, routine tasks only
  3. Social: Low-stakes interactions
  4. Work: Clear backlog, inbox zero, easy wins

API Integration

The Oura data is available at:

GET /api/oura/daily

Response structure:

{
  "readiness": 78,
  "sleep_score": 82,
  "hrv_balance": "above_baseline",
  "activity_score": 65,
  "recommendation": "Normal productivity day"
}

Using This Skill

When a user asks about scheduling or prioritization:

  1. Check current Oura data
  2. Match task difficulty to energy level
  3. Suggest appropriate activities
  4. Warn about low-energy pitfalls
  5. Recommend recovery if needed

Example response:

Based on your Oura data:
- Readiness: 72 (normal)
- Sleep: 68 (slightly low)
- HRV: below baseline

Recommendation: This is a "maintenance day" not a "breakthrough day."
Focus on:
✓ Clearing email backlog
✓ Quick task completions
✓ Light planning
✗ Avoid: Complex coding, important decisions, new initiatives

Consider a 20-min walk to boost HRV before afternoon work.
