What it does

Weather is an agent skill from vellum-ai/vellum-assistant. Get current weather conditions and forecasts for any location

Its SKILL.md is about 720 tokens, which your agent loads only when the skill is triggered. The skill folder holds 7 other files, including scripts and assets (for example `scripts/__tests__/get-weather.test.ts`, `scripts/service.ts` and `scripts/weather-cli.ts`).

The repository describes itself as: An AI Assistant that’s easy to setup, does your work 24/7, knows your preferences and gets better over time. The licence is MIT.

Example prompts

“/weather”

Requirements

Node.js

What it can do on your machine

Read from SKILL.md and the folder at commit 33cc983. 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
Ships 3 files in scripts/ (TypeScript), which the agent can run.
Shell commands in SKILL.md call:
- bun
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Weather loads about 715 tokens when it runs. Until then it costs about 17 tokens; SKILL.md has 229 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~17
When it runs · the whole SKILL.md, loaded when a task matches: ~715

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); the scripts in this folder are not scanned.

name: weather
description: Get current weather conditions and forecasts for any location
metadata.icon: assets/icon.svg
metadata.emoji: 🌤️

You are a weather assistant. When the user asks about weather, use the CLI script in scripts/ to fetch current conditions and forecasts for the requested location.

Usage

Run the weather command via:

bash

bun run scripts/weather-cli.ts "<location>" [--units celsius|fahrenheit] [--days <n>]

Examples

Current conditions: bun run scripts/weather-cli.ts "San Francisco"
Multi-day forecast: bun run scripts/weather-cli.ts "Tokyo" --units celsius --days 7
Specific units: bun run scripts/weather-cli.ts "London" --units celsius

Output Format

The command returns JSON with:

json

{
  "ok": true,
  "text": "Human-readable weather summary",
  "data": {
    "location": { "name": "...", "latitude": ..., "longitude": ... },
    "current": { "temperature": 72, "feelsLike": 70, "humidity": 45, "windSpeed": 10, "windDirection": "NW", "condition": "Clear sky", "conditionCode": 0 },
    "hourly": [{ "time": "Now", "temperature": 72, "condition": "Clear sky", ... }],
    "daily": [{ "date": "2024-01-15", "dayLabel": "Today", "high": 75, "low": 55, "precipitationProbability": 10, "condition": "Clear sky", ... }],
    "units": { "temperature": "F", "speed": "mph" }
  }
}

Presenting Results

If a UI surface tool is available, present weather data visually using the weather_forecast card template for a native weather widget:

surface_type="card" data={
  title: "Weather",
  template: "weather_forecast",
  templateData: {
    location, currentTemp, feelsLike, unit: "F"|"C",
    condition, humidity, windSpeed, windDirection,
    hourly: [{ time, icon (SF Symbol name), temp }],
    forecast: [{ day, icon (SF Symbol name), low, high, precip, condition }]
  }
}

Map weather condition codes to SF Symbol names (e.g. "sun.max.fill", "cloud.rain.fill", "cloud.fill", "snowflake").

Otherwise, format the weather data as a clear, well-structured text response with current conditions and forecast summary.

Temperature Units

Default unit is Fahrenheit. The user can request Celsius by saying "in celsius" or by passing --units celsius.

Forecast Days

Default is 10 days. The user can request anywhere from 1 to 16 days via --days <n>.
Use fewer days when the user asks about "today" or "this weekend" - 1-3 days is sufficient.
Use more days when the user asks for an extended or long-range forecast.

Tips

If the user provides an ambiguous location (e.g. "Springfield"), the geocoding API picks the most prominent match. If the result seems wrong, suggest the user be more specific (e.g. "Springfield, IL").
The command fetches live data from the Open-Meteo Weather API.

Questions about Weather

What does Weather do?

Get current weather conditions and forecasts for any location. Weather is an agent skill from vellum-ai/vellum-assistant.

How do I install Weather in Claude Code?

Run `npx skills add vellum-ai/vellum-assistant --skill weather -a claude-code`. Or copy the skill folder (skills/weather in vellum-ai/vellum-assistant) into .claude/skills/weather in your project. Claude Code loads it when a task matches its description.

How do I install Weather in Codex?

Run `npx skills add vellum-ai/vellum-assistant --skill weather -a codex`. Or copy the skill folder (skills/weather in vellum-ai/vellum-assistant) into .agents/skills/weather in your project. Codex loads it when a task matches its description.

Can I use Weather in Cursor, Gemini CLI or GitHub Copilot?

Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add vellum-ai/vellum-assistant --skill weather -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/weather, .gemini/skills/weather, .github/skills/weather and .opencode/skills/weather in your project.

What does Weather need to run?

Going by SKILL.md and its folder, Weather needs TypeScript for the scripts in its folder and the command-line tools its instructions call (bun). Our summary lists: Node.js.

Does Weather access the network?

SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.

Is Weather safe to install?

Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. The check reads SKILL.md only: the scripts in the folder are not scanned, so read them before running anything.

What licence does Weather use?

Weather is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.

How many tokens does Weather use?

About 715 tokens (SKILL.md is roughly 2.9k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.

What are the alternatives to Weather?

Skills that share tags, products or a category with Weather: Weather (openclaw/openclaw, 392k stars), Weather Lookup (sipeed/picoclaw, 30k stars), Timesfm Forecasting (K-Dense-AI/scientific-agent-skills, 48k stars) and Weather (iflytek/skillhub, 5.2k stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.

Who maintains Weather?

vellum-ai (a GitHub organization) maintains it in vellum-ai/vellum-assistant, which has 1,408 GitHub stars. The repository holds 108 skills in this directory. The repository was last updated on October 9, 2026.

Source: vellum-ai/vellum-assistant on GitHub. Facts on this page come from the repository at the commit we read; the author's words are quoted as theirs.
