A development helper for Garmin Connect IQ apps, the programs that run on Garmin watches and devices. It builds, runs, packages, and answers development questions using a cached copy of Garmin’s official documentation.

Use it to develop watch faces, data fields, widgets, and device apps; compile them; run them in the simulator; create store packages; and check Connect IQ APIs and how-to guidance.

It avoids manually finding SDK and Java paths and looking through platform documentation. It also provides one workflow across Windows, macOS, and Linux.

garmin-dev — Skill for Claude Code by athitupakan

Install

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Any agent

npx skills add athitupakan/garmin-dev-skills --skill garmin-dev

Clone the repo

git clone --depth 1 https://github.com/athitupakan/garmin-dev-skills

Made for: Claude Code.

Or install garmin-dev, the plugin that ships this one along with the rest of its 1 skill, 6 commands.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00269	$0.04334
Opus 5	$0.00134	$0.02167
Sonnet 5	$0.00054	$0.00867
Haiku 4.5	$0.00027	$0.00433

Measured 9d ago against content hash 91960cb2538b, method: parsed. Prices are Anthropic first-party input rates as of 2026-09-09, from the pricing page.

Security

Grade A, and why

garmin-dev scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

The scan reads SKILL.md. This mod also ships 2 executable files (references/connect-iq-docs/_refresh/convert.js, references/connect-iq-docs/_refresh/htmlmd.js), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 151 lines — stays where its author put it; the contents beside it link to each section on GitHub.

garmin-dev

Cross-platform workflow for compiling, running, and packaging Connect IQ apps — plus a cached mirror of Garmin's official docs to ground every API / how-to answer in what the platform actually allows.

OS support: Windows (PowerShell 5.1+) · macOS (Bash, Apple Silicon + Intel) · Linux (Bash, Ubuntu LTS officially supported by Garmin)

How dispatch picks the right script

The skill ships parallel script sets — one per OS family. Detect OS first, then invoke the matching command:

OS	Detect via	Script set
Windows	`$env:OS = "Windows_NT"` (or `$PSVersionTable.Platform = "Win32NT"`)	`scripts/windows/*.ps1`
macOS	`uname -s` returns `Darwin`	`scripts/posix/*.sh`
Linux	`uname -s` returns `Linux`	`scripts/posix/*.sh`

Every script auto-detects SDK + JDK at runtime — no per-machine path config needed. Every script reads manifest.xml from cwd for project name + device id, so always invoke from the project root (not from the skill folder).

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

garmin-dev is a skill published in the GitHub repository athitupakan/garmin-dev-skills (2 stars, last pushed 3mo ago), licensed MIT. It adds 269 tokens to every session and 4,334 once invoked, about $0.0013 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
