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.

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 | $0.00037 | $0.00275 |
| Opus 5.5 | $0.00015 | $0.00110 |
| Sonnet 5.5 | $0.00007 | $0.00055 |
| Haiku 4.5 | $0.00004 | $0.00028 |
Grade A, and why
garmin 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 1mo ago.
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.
This is a copy
83% identical to google-health — 16 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
What it actually says
Garmin — skill or MCP
Same binary either way. Do not duplicate the API client.
Choose a surface
MCP — tools appear natively after stdio/HTTP config:
{ "mcpServers": { "garmin": { "command": "npx", "args": ["-y", "garmin-mcp-unofficial"] } } }
Do not put mutation flags in that snippet.
Skill / CLI — no MCP client required. Same tools:
npx -y garmin-mcp-unofficial call garmin_connection_status --json '{}'
If MCP tools named garmin_* are already available, use them. Do not also shell out.
Loop
- Call
garmin_connection_status(ordoctor --jsonwhen that exists). - Use read tools as asked.
- Stop on
USER_ACTION_REQUIRED. Do not invent env flags. Do not enable mutations from this skill.
Never
- Paste tokens into git, chat logs, or the prompt
- Copy a mutations-enabled assignment into config
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 is a skill published in the GitHub repository davidmosiah/garmin-mcp (13 stars, last pushed yesterday), licensed MIT. It adds 37 tokens to every session and 275 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings. It is 83% identical to google-health, differing in 16 lines, and is treated as a copy.
