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.

SkillSpector: 1 finding, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- medium Rogue Agent · line 92 Skill establishes unauthorized persistence across sessions via cron jobs, startup scripts, or state files. Session persistence allows an attacker to maintain access beyond the current interaction.Fix: Remove any persistence mechanisms (cron jobs, startup scripts, state files). Skills should not maintain state across sessions without explicit user consent.
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 | $0.00041 | $0.02605 |
| Opus 5 | $0.00020 | $0.01303 |
| Sonnet 5 | $0.00008 | $0.00521 |
| Haiku 4.5 | $0.00004 | $0.00261 |
Grade A, and why
ghealth 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 12d 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.
How it starts
The opening of the file, as written. The whole thing — 168 lines — stays where its author put it; the contents beside it link to each section on GitHub.
ghealth
CLI for the Google Health API v4. 40 verified data types.
Prerequisites: See ../ghealth-shared/SKILL.md for auth, setup, global flags.
Choosing the right operation
| Goal | Operation | Example |
|---|---|---|
| Daily totals (steps, distance, calories) | daily-rollup |
ghealth data steps daily-rollup --from 2026-03-22 --to 2026-03-29 |
| Individual readings (HR, weight, SpO2) | list |
ghealth data heart-rate list --from today --limit 20 |
| Sessions (exercise, sleep) | list |
ghealth data exercise list --from 2026-03-01 |
| Daily summaries (resting HR, HRV, resp rate) | list |
ghealth data daily-resting-heart-rate list --from 2026-03-01 |
| Merged multi-source data | reconcile |
ghealth data weight reconcile --from 2026-01-01 |
Why this matters: steps list returns minute-level intervals without counts. Use daily-rollup to get actual step totals (countSum). Same for distance (millimetersSum) and floors.

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.

ghealth is a skill published in the GitHub repository Google-Health-API/google-health-cli (243 stars, last pushed 2mo ago), licensed Apache-2.0. It adds 41 tokens to every session and 2,605 once invoked, about $0.0002 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 2026-08-30.
