At a glance

Get current weather and forecasts using free APIs (no API key required).

  • Asked about weather
  • SKILL.md covers Setup, wttr.in (Primary), Open-Meteo (JSON API) and Examples
  • Calls curl, python3 and npx; reaches api.open-meteo.com and api.gooseworks.ai; needs GOOSEWORKS_API_KEY
  • Climate conditions for any location

What it does

Weather is an agent skill from gooseworks-ai/goose-skills. Get current weather and forecasts using free APIs (no API key required). Use when asked about weather, temperature, forecasts, or climate conditions for any location.

Its SKILL.md is about 590 tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file (for example `skill.meta.json`).

The repository describes itself as: Library of Growth & GTM skills + data APIs for Claude Code, Codex, Cursor to run ads, social, content, lead gen, seo and data scraping. The licence is MIT.

When your agent uses it

  • Asked about weather
  • Climate conditions for any location

Example prompts

  • “/weather”

Requirements

  • Python 3
  • Node.js
  • A credential in GOOSEWORKS_API_KEY

What it can do on your machine

Read from SKILL.md and the folder at commit c650c6d. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • curl
    • python3
    • npx

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Hosts in commands or code, which the agent is likely to contact:

    • api.open-meteo.com
    • api.gooseworks.ai
    • geocoding-api.open-meteo.com

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names these keys or tokens, usually read from environment variables:

    • GOOSEWORKS_API_KEY

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Weather loads about 587 tokens when it runs. Until then it costs about 44 tokens; SKILL.md has 134 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~44
When it runs · the whole SKILL.md, loaded when a task matches
~587

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Setup

Read your credentials from ~/.gooseworks/credentials.json:

bash
export GOOSEWORKS_API_KEY=$(python3 -c "import json;print(json.load(open('$HOME/.gooseworks/credentials.json'))['api_key'])")
export GOOSEWORKS_API_BASE=$(python3 -c "import json;print(json.load(open('$HOME/.gooseworks/credentials.json')).get('api_base','https://api.gooseworks.ai'))")

If ~/.gooseworks/credentials.json does not exist, tell the user to run: npx gooseworks login

All endpoints use Bearer auth: -H "Authorization: Bearer $GOOSEWORKS_API_KEY"

Get weather data using free services - no API keys needed.

wttr.in (Primary)

Fast, simple, works everywhere.

Quick check:

bash
curl -s "wttr.in/London?format=3"
# Output: London: ⛅️ +8°C

Compact format:

bash
curl -s "wttr.in/London?format=%l:+%c+%t+%h+%w"
# Output: London: ⛅️ +8°C 71% ↙5km/h

Full forecast:

bash
curl -s "wttr.in/London?T"
Format Codes
CodeMeaning
%cWeather condition emoji
%tTemperature
%hHumidity
%wWind
%lLocation
%mMoon phase
Tips
  • URL-encode spaces: wttr.in/New+York or wttr.in/San%20Francisco
  • Airport codes work: wttr.in/JFK, wttr.in/SFO
  • Units: ?m metric, ?u USCS (Fahrenheit)
  • Limit days: ?1 today only, ?0 current only
  • Save as image: curl -s "wttr.in/Berlin.png" -o weather.png

Open-Meteo (JSON API)

Better for programmatic use. Free, no key.

bash
curl -s "https://api.open-meteo.com/v1/forecast?latitude=37.77&longitude=-122.42&current_weather=true"

Response includes: temperature, windspeed, weathercode, time.

Get coordinates first
bash
curl -s "https://geocoding-api.open-meteo.com/v1/search?name=San+Francisco&count=1"

Examples

San Francisco right now:

bash
curl -s "wttr.in/San+Francisco?format=3"

Tokyo 3-day forecast:

bash
curl -s "wttr.in/Tokyo?3T"

JSON weather for coordinates:

bash
curl -s "https://api.open-meteo.com/v1/forecast?latitude=35.68&longitude=139.69&current_weather=true&hourly=temperature_2m"
