Weather Command

You will invoke both the weather-fetcher and weather-transformer agents to complete the weather workflow.

Task

Execute the complete weather workflow for Karachi, Pakistan by launching two specialized agents sequentially:

1. weather-fetcher agent: Retrieves the current temperature from wttr.in API
2. weather-transformer agent: Applies transformations from input/input.md to the temperature

Instructions

Launch both agents sequentially, waiting for each to complete before starting the next:

Step 1: Invoke weather-fetcher first:

• subagent_type: "weather-fetcher"
• description: "Fetch Karachi temperature"
• prompt: "Fetch the current temperature for Karachi, Pakistan in Celsius from the wttr.in API. Use the WebFetch tool to retrieve the temperature from wttr.in/Karachi?format=%t and return the numeric temperature value in Celsius in your final report."
• model: "haiku"

Step 2: After weather-fetcher completes, invoke weather-transformer:

• subagent_type: "weather-transformer"
• description: "Transform temperature data"
• prompt: "You are the weather-transformer agent. The current temperature for Karachi, Pakistan is {temperature}°C (use the temperature value from the weather-fetcher agent). Read the transformation rules from input/input.md, apply those rules to the temperature value, and write the formatted results to output/output.md. Return a summary with the original temperature, transformation applied, and final result."
• model: "haiku"

Important

• Launch agents SEQUENTIALLY, not in parallel - weather fetching may take time
• Wait for weather-fetcher to complete before launching weather-transformer
• Pass the fetched temperature to the weather-transformer agent in the prompt
• Provide a clear final summary showing results from both agents
