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 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 2mo 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.

Weather Skill

Get current weather conditions and forecasts.

Metis / magic-cli(必读)

  • 优先使用内置 weather 工具(HTTP 直连 wttr.in,不要用 Shell 执行 curl)。在 Windows 上 Shell 往往会走 PowerShell,易出现 Invoke-WebRequest 交互或参数解析问题。
  • 地点尽量用 英文(如 Nanjing、Beijing),与工具参数一致。
  • 下列 curl 示例仅作 原理说明 或你在 非 Metis 环境 下手动验证时使用;在本 CLI / 网关内以 weather 工具为准。

When to Use

✅ USE this skill when:

  • "What's the weather?"
  • "Will it rain today/tomorrow?"
  • "Temperature in [city]"
  • "Weather forecast for the week"
  • Travel planning weather checks

When NOT to Use

❌ DON'T use this skill when:

  • Historical weather data → use weather archives/APIs
  • Climate analysis or trends → use specialized data sources
  • Hyper-local microclimate data → use local sensors
  • Severe weather alerts → check official NWS sources
  • Aviation/marine weather → use specialized services (METAR, etc.)

Location

Always include a city, region, or airport code in weather queries.

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.
