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 | $0.00570 | $0.00570 |
| Opus 5 | $0.00285 | $0.00285 |
| Sonnet 5 | $0.00114 | $0.00114 |
| Haiku 4.5 | $0.00057 | $0.00057 |
Grade A, and why
google-health-cli AGENTS.md scanned grade A with 1 finding 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 5d 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

The opening of the file, as written. The whole thing — 59 lines — stays where its author put it; the contents beside it link to each section on GitHub.
ghealth — Development Guide
What is this
ghealth is a CLI wrapping the Google Health API v4. Primary users are AI agents (OpenClaw, Claude Code, Codex, coding agents) that need structured health data access — steps, heart rate, sleep, exercise, weight, SpO2, HRV. Human developers use it too.
The CLI handles OAuth, pagination, response simplification, and contextual hints so agents can focus on the health question, not API plumbing.
Progressive disclosure
Information is layered so agents load only what they need:
ghealth --help→ commands overviewghealth data --help→ list vs daily-rollup guidance, all 40 typesghealth data <type> --help→ available operationsghealth data <type> <op> --help→ flags for that operationghealth schema types→ machine-readable type registryghealth schema type <name>→ fields, parameters, scope for one type_hintsin responses → contextual next-step suggestionsskills/ghealth/SKILL.md→ non-obvious patterns, gotchas (load once)
Build
go build -o ghealth .
go vet ./...
Verify against the live API: ghealth auth status, then ghealth data steps daily-rollup --from 2026-03-22 --to 2026-03-29.
Workflow
- Feature branches + PRs — never commit to main directly
- Only register data types verified against the live API, not from docs alone
- Test new types with curl before adding to the registry

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.
