Garmin AI Skill

Canonical version: Garmin AI Skill.

An open-source AI Agent Skill (MIT License) that fetches health and exercise data from Garmin Connect and makes it available to AI agents. I built it to pipe data from my Garmin Venu 3 straight into my Obsidian daily notes.

Why

Garmin collects a ton of high-quality health and exercise data (sleep stages, HRV, body battery, training readiness, VO2 max, workouts, etc.), but that data is locked inside Garmin Connect. Getting it into a personal knowledge management system for analysis, correlation with other life data, or AI coaching requires scraping, manual export, or fragile automations.

This skill packages the access pattern as a reusable AI Agent Skill, so any compatible AI agent (e.g., Claude Code) can pull Garmin data on demand and do something useful with it; logging, coaching, visualizing, etc.

Features

• Authenticates against Garmin Connect
• Fetches daily health metrics (sleep, HRV, stress, body battery, resting heart rate, ...)
• Fetches exercise sessions (runs, gym, walks, cycling, swimming)
• Fetches training metrics (readiness, status, load, recovery, VO2 max)
• Structured output suitable for writing into markdown frontmatter

Installation

One-liner install via the AI Agent Skills CLI:

npx skills add dsebastien/ai-skill-garmin

Note that the above command uses npx, one of the tools included in Node.js / npm.

How I use it

I use the skill from Claude Code to fill health and exercise properties in my Obsidian daily notes. From there:

• The Life Tracker plugin for Obsidian visualizes the data
• My Health Obsidian Base surfaces trends
• AI can coach me on top of the captured data (e.g., half-marathon preparation, recovery, sleep hygiene)

The whole pipeline stays inside plain markdown files I own, not a vendor silo.
