-1. Use the AskUserQuestion tool to ask the user whether they want the temperature in Celsius or Fahrenheit
-2. Use the weather-fetcher agent to retrieve the current temperature from wttr.in API in the requested unit
-3. Use the weather-transformer agent to read transformation rules from input/input.md and apply them to the temperature
-4. Write the results to output/output.md
-
-Launch the agents sequentially (not in parallel) and provide a clear summary showing:
-- Temperature unit requested
-- Original temperature
-- Transformation applied
-- Final result

+# Weather Karachi Skill
+
+Fetch the current temperature for Karachi, Pakistan and apply transformations.
+
+## Workflow
+
+1. Use the AskUserQuestion tool to ask the user whether they want the temperature in Celsius or Fahrenheit
+2. Use the weather-fetcher subagent to retrieve the current temperature from wttr.in API in the requested unit
+3. Use the weather-transformer subagent to read transformation rules from input/input.md and apply them to the temperature
+4. Write the results to output/output.md
+
+## Subagent Invocation
+
+Use the Task tool to invoke subagents sequentially (not in parallel) to maintain data dependencies.
+
+### Step 1: Fetch Temperature
+
+Use the Task tool to invoke the weather-fetcher subagent:
+- subagent_type: weather-fetcher
+- description: Fetch Karachi temperature
+- prompt: Fetch the current temperature for Karachi, Pakistan in [unit requested by user] from wttr.in API. Return the numeric temperature value in your final report.
+- model: haiku
+
+Wait for the subagent to complete and extract the temperature value from its final report.
+
+### Step 2: Transform Temperature
+
+Use the Task tool to invoke the weather-transformer subagent:
+- subagent_type: weather-transformer
+- description: Transform temperature
+- prompt: Apply transformation rules from input/input.md to the temperature value: [X] degrees. Write formatted results to output/output.md.
+- model: haiku
+
+Wait for the subagent to complete.
+
+## Critical Requirements
+
+1. **Use Task Tool Only**: DO NOT use bash commands to invoke subagents. You must use the Task tool.
+2. **Sequential Execution**: Launch subagents one at a time, wait for completion before launching the next.
+3. **Data Passing**: Extract the temperature from weather-fetcher's report and pass it to weather-transformer's prompt.
+
+## Output Summary
+
+Provide a clear summary to the user showing:
+- Temperature unit requested
+- Original temperature fetched
+- Transformation rule applied (from input/input.md)
+- Final transformed result (written to output/output.md)
