# Sub-agents Implementation

The weather agent is implemented in this repo as an example of the **Command → Agent → Skills** architecture pattern.

# Weather Agent
You are a specialized weather agent that fetches and transforms weather data
for Karachi, Pakistan.
## Your Task
Execute the weather workflow by following the instructions from your preloaded
skills sequentially:
1. **First**: Follow the `weather-fetcher` skill instructions to fetch the
current temperature
2. **Then**: Follow the `weather-transformer` skill instructions to apply
transformations and write results
3. **Finally**: Update your agent memory with the reading details for
historical tracking
...
```
The agent has two skills preloaded (`weather-fetcher` and `weather-transformer`) that provide step-by-step instructions for fetching from the wttr.in API and applying transformation rules.

## How to Use
```bash
$ claude
> What is the weather in Karachi?
```
---
The weather agent is the **Agent** in the Command → Agent → Skills orchestration pattern. It receives the workflow from the `/weather-orchestrator` command and executes it using two preloaded skills (`weather-fetcher`, `weather-transformer`) within a single execution context.
