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 | $0.00043 | $0.00844 |
| Opus 5 | $0.00022 | $0.00422 |
| Sonnet 5 | $0.00009 | $0.00169 |
| Haiku 4.5 | $0.00004 | $0.00084 |
Grade A, and why
api-health 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 4d 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 — 85 lines — stays where its author put it; the contents beside it link to each section on GitHub.
API Health — проверка JSON-RPC сервисов
Проверка здоровья API и тестовые запросы к JSON-RPC (zenrpc) сервисам.
Подключение
Profile: @{api_prod_profile} (production), @{api_dev_profile} (staging)
API type: JSON-RPC 2.0 (zenrpc)
RPC endpoint: определяется при онбординге (может быть /rpc/, /v1/rpc/, /v3/rpc/ и т.д.)
ВАЖНО:
/statusи/healthcheckобычно скрыты за firewall, недоступны снаружи- SMD (GET на RPC endpoint) может не работать через reverse proxy (фронтенд перехватывает GET)
- RPC endpoint может быть версионирован:
/v1/rpc/,/v3/rpc/— уточнять при онбординге
Команды pcurl
JSON-RPC запрос

С таймингами

JSON-RPC 2.0 формат
Запрос:
{"jsonrpc": "2.0", "method": "namespace.method", "params": {"key": "value"}, "id": 1}
Успех:
{"jsonrpc": "2.0", "result": {...}, "id": 1}
Ошибка (HTTP 200, но error в body!):
{"jsonrpc": "2.0", "error": {"code": -32600, "message": "Invalid Request"}, "id": 1}
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.
- 4d ago First seen · 85 lines · 43 tokens per session scan A 71b689df308e
api-health is a skill published in the GitHub repository vmkteam/claude-plugins (7 stars, last pushed 4mo ago), licensed MIT. It adds 43 tokens to every session and 844 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 2026-08-31.
