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 | $0.00024 | $0.00417 |
| Opus 5 | $0.00012 | $0.00209 |
| Sonnet 5 | $0.00005 | $0.00083 |
| Haiku 4.5 | $0.00002 | $0.00042 |
Grade A, and why
weather-fetcher 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 11d 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
94% identical to weather-fetcher — 24 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
Weather Fetcher 技能
本技能提供获取当前天气数据的说明。
任务
以请求的单位（摄氏度或华氏度）获取阿联酋迪拜的当前温度。
说明
-
获取天气数据：使用 WebFetch 工具从 Open-Meteo API 获取迪拜的当前天气数据。
摄氏度：
- URL:
https://api.open-meteo.com/v1/forecast?latitude=25.2048&longitude=55.2708¤t=temperature_2m&temperature_unit=celsius
华氏度：
- URL:
https://api.open-meteo.com/v1/forecast?latitude=25.2048&longitude=55.2708¤t=temperature_2m&temperature_unit=fahrenheit
- URL:
-
提取温度：从 JSON 响应中提取当前温度：
- 字段：
current.temperature_2m - 单位标签位于：
current_units.temperature_2m
- 字段：
-
返回结果：清晰地返回温度值和单位。
预期输出
完成本技能的说明后：
Current Dubai Temperature: [X]°[C/F]
Unit: [Celsius/Fahrenheit]
注意事项
- 仅获取温度，不要进行任何转换或写入任何文件
- Open-Meteo 免费使用，无需 API 密钥，使用基于坐标的查找以确保可靠性
- 迪拜坐标：纬度 25.2048，经度 55.2708
- 清晰地返回数字温度值和单位
- 根据调用者的请求支持摄氏度或华氏度
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.

weather-fetcher is a skill published in the GitHub repository rongxinzy/claude-code-best-practice-zh (6 stars, last pushed 5mo ago), licensed MIT. It adds 24 tokens to every session and 417 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. It is 94% identical to weather-fetcher, differing in 24 lines, and is treated as a copy.
