.claude/skills/weather-fetcher/SKILL.md

weather-fetcher is a skill for Claude Code from clxzl/claude-code-best-practice-cn. It costs 21 tokens per session (410 once invoked), scanned A, original, MIT.

A skill for retrieving Dubai's current temperature from the free Open-Meteo weather service, in Celsius or Fahrenheit.

In plain words
What is it for?
Use it when the agent needs only Dubai's current temperature. It returns the value together with its Celsius or Fahrenheit unit.
Why use it?
It provides a focused temperature lookup without an API key or manual unit conversion. The instructions use Dubai's coordinates so the location is fixed and unambiguous.

Token cost

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.

Security

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.

What it actually says

天气获取 Skill

此 Skill 提供获取当前天气数据的指令。

任务

以请求的单位(摄氏度或华氏度)获取迪拜的当前温度。

指令

  1. 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&current=temperature_2m&temperature_unit=celsius

    华氏度

    • URL:https://api.open-meteo.com/v1/forecast?latitude=25.2048&longitude=55.2708&current=temperature_2m&temperature_unit=fahrenheit
  2. 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
  3. 返回结果:清晰地返回温度值和单位。

预期输出

完成此 Skill 的指令后:

Current Dubai Temperature: [X]°[C/F]
Unit: [Celsius/Fahrenheit]

注意事项

  • 仅获取温度,不进行任何转换或写入任何文件
  • Open-Meteo 免费、无需 API 密钥,使用基于坐标的查询以确保可靠性
  • 迪拜坐标:纬度 25.2048,经度 55.2708
  • 清晰地返回数值温度值和单位
  • 根据调用者的请求支持摄氏度和华氏度

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.
