Canonical version: A Garmin AI Skill and Richer Health Tracking in Obsidian.

Today I shipped a few things around health tracking in my Obsidian vault. They all click together.

A Garmin AI Skill

I've built and released a small AI skill that fetches data from Garmin Connect. It's an open-source AI Agent Skill under the MIT license: https://github.com/dsebastien/ai-skill-garmin

Install is a one-liner:

npx skills add dsebastien/ai-skill-garmin

I use it to pull health and exercise data from my Garmin Venu 3 straight into my Obsidian daily notes. No copy/paste, no dashboard hopping; the AI reads Garmin, fills in the right frontmatter properties, and moves on.

A Much Richer Health Schema

The capture is only useful if there's a proper structure to capture into. So I extended my daily note template with a long list of new health and exercise properties: sleep stages, HRV, body battery, training readiness, VO2 max, intensity minutes, exercise sessions, nutrition, supplements, and more.

Once the data is in the frontmatter, the rest is just consumption. I can visualize it with the Life Tracker plugin for Obsidian:

An Upgraded Health Base

I also improved my Health Obsidian Base (also part of the Obsidian Starter Kit) to surface the new properties and make trends easier to spot. Bases are becoming a serious dashboard layer on top of the vault; I'm leaning into them more and more.

AI coaching on my own data

The capture is the boring part. The real payoff is what I can do with the data once it's in the vault. Because everything lives as plain markdown and frontmatter, I can now ask AI for coaching and analysis on top of it.

For instance, here's what it tells me about my half-marathon preparation:

2026-04-15 - half marathon prep 01
2026-04-15 - half marathon prep 02
2026-04-15 - half marathon prep 03

This is the pattern I keep coming back to lately: own your data as plain files, then point AI at it. The payoff is huge, and nothing is locked in a vendor's silo.
