Implemented

The weather agent is implemented as an example of the Command > Agent > Skill architecture pattern, demonstrating two distinct skill patterns.

# 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

$ claude
> what is the weather in dubai?

How to Implement

You can create an agent using the /agents command:

$ 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

Orchestration Workflow

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.

Component	Role	Example
Command	Entry point, user interaction	/weather-orchestrator
Agent	Fetches data with preloaded skill (agent skill)	weather-agent with weather-fetcher
Skill	Creates output independently (skill)	weather-svg-creator
