A skill for checking current weather with live online data, using either a saved location or a city supplied for one request.

Use it to see current conditions or a forecast, set or change the saved city, and clear the saved location.

It avoids relying on outdated weather information and can remember a default location for future checks.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00041	$0.01137
Opus 5.5	$0.00016	$0.00455
Sonnet 5.5	$0.00008	$0.00227
Haiku 4.5	$0.00004	$0.00114

Security

Grade A, and why

weather 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 1mo 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.

Weather

Check the current weather for your location using live data from Open-Meteo (free, no API key needed).

Preferences

Read ~/.claude/skills/weather/preferences.md using the Read tool. If not found, no preferences are set.

Command routing

Check $ARGUMENTS:

help → display help then stop
config → interactive setup then stop
reset → delete ~/.claude/skills/weather/preferences.md, confirm, stop
anything else (including empty) → run the skill

Help

Weather — Check current weather for your location

Usage:
  /weather                     Show weather for saved location
  /weather Berlin              Show weather for Berlin
  /weather config              Set your default location
  /weather reset               Clear saved location
  /weather help                This help

Examples:
  /weather                     Uses your saved city
  /weather "New York"          One-off check for New York
  /weather Tokyo               One-off check for Tokyo

Current preferences:
  (shown above under Preferences)

Config

Use AskUserQuestion:

Q1 — "What city are you in?" (text input via Other)

Options: suggest common cities as quick picks, plus Other for custom input

Q2 — "Temperature unit?"

Celsius (default)
Fahrenheit

Save to ~/.claude/skills/weather/preferences.md.

Reset

Delete ~/.claude/skills/weather/preferences.md and confirm: "Preferences cleared. Using defaults."

First-time detection

If no preferences file exists and no city argument was provided:

Use AskUserQuestion to ask: "Where are you located? (city name)"
After getting weather, offer to save the location

Steps

1. Determine location

If $ARGUMENTS contains a city name (not help/config/reset) → use that city
Else if preferences has a saved city → use that
Else → ask via AskUserQuestion: "What city should I check the weather for?"

2. Geocode the city

Use WebFetch to call the Open-Meteo geocoding API:

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.
