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 | $0.00058 | $0.00336 |
| Opus 5.5 | $0.00023 | $0.00134 |
| Sonnet 5.5 | $0.00012 | $0.00067 |
| Haiku 4.5 | $0.00006 | $0.00034 |
Grade A, and why
earthquake 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 7d 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.
What it actually says
地震查询技能
工具
| 工具 | 用途 | 参数 |
|---|---|---|
recent_earthquakes |
查询最近的地震 | limit（条数，默认 5）、minMagnitude（最小震级，默认 3）、region（地区关键词）、hours（时间范围，默认 24） |
Example:
用户: 刚才四川是不是地震了？
→ recent_earthquakes(region="四川", hours=6, minMagnitude=2)
注意
- 地区是对地点文字的关键词匹配；
中国/国内表示中国境内（含台湾）。 - 回答时说明数据来源与发震时刻的时区；数据源不可用时如实告知，不要编造地震信息。

What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

earthquake is a skill published in the GitHub repository zhinjs/zhin (136 stars, last pushed today), licensed MIT. It adds 58 tokens to every session and 336 once invoked, about $0.0002 per session on Opus 5.5. 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 2026-10-21.
