The weather agent is implemented in this repo as an example of the **Command → Agent → Skill** architecture pattern, demonstrating two distinct skill patterns.

```yaml

description: Use this agent PROACTIVELY when you need to fetch weather data for
  Dubai, UAE. This agent fetches real-time temperature from Open-Meteo
  using its preloaded weather-fetcher skill.

# Weather Agent

You are a specialized weather agent that fetches weather data for Dubai,
UAE.

## Your Task

Execute the weather workflow by following the instructions from your preloaded
skill:

1. **Fetch**: Follow the `weather-fetcher` skill instructions to fetch the
   current temperature
2. **Report**: Return the temperature value and unit to the caller
3. **Memory**: Update your agent memory with the reading details for
   historical tracking

...
```

The agent has one preloaded skill (`weather-fetcher`) that provides instructions for fetching from Open-Meteo. It returns the temperature value and unit to the calling command.

## ![How to Use](../!/tags/how-to-use.svg)

```bash
$ claude
> what is the weather in dubai?
```

## ![How to Implement](../!/tags/how-to-implement.svg)

You can create an agent using the `/agents` command, 
```bash
$ claude
> /agents
```

or ask Claude to create one for you — it will generate the markdown file with YAML frontmatter and body in `.claude/agents/<name>.md`

The weather agent is the **Agent** in the Command → Agent → Skill orchestration pattern. It receives the workflow from the `/weather-orchestrator` command and fetches temperature using its preloaded skill (`weather-fetcher`). The command then invokes the standalone `weather-svg-creator` skill to create the visual output.
