The Setup

Kris Puckett switched to Obsidian for docs/data and used Claude Code to:

  1. Build custom iOS app connecting Apple Health to Mac mini via CLI and local network
  2. Refactor Obsidian theme and layout
  3. Incorporate health visualization in daily briefing

"I love this era of creativity."

Health Dashboard

Health Dashboard

Active Health dashboard showing:

  • Sleep: 7h12m (Deep: 1h08m, REM: 1h40m)
  • HRV: 100ms ↑
  • RHR: 56bpm →
  • SpO2: 95.9% →
  • Steps: 98 ↓
  • Cals: 16cal ↓
  • Macros: 1,606 cal | 245g P | 24g F | 93g C
  • Sleep HR: avg 57 / low 47 / high 70 | Dip: 36.7%
  • Baevsky SI: 5.0 | Sleep Efficiency: 97%

Why This Matters

Demonstrates how AI coding agents enable non-developers to build deeply personalized integrations with markdown-based knowledge systems. The combination of:

  • Obsidian's markdown foundation
  • Claude Code's ability to build custom tools
  • Local network + CLI integrations
  • Personal health data visualization

Results in bespoke knowledge infrastructure that would traditionally require hiring developers or using rigid SaaS products.
