+
+# Weather Fetcher Skill
+
+This skill provides instructions for fetching current weather data.
+
+## Task
+
+Fetch the current temperature for Karachi, Pakistan in degrees Celsius (Centigrade).
+
+## Instructions
+
+1. **Fetch Weather Data**: Use the WebFetch tool to get current weather data for Karachi from wttr.in API:
+   - URL: `https://wttr.in/Karachi?format=j1`
+   - This returns JSON format weather data
+
+2. **Extract Temperature**: From the JSON response, extract the current temperature in Celsius from the `current_condition` section.
+
+3. **Store Result**: Keep the temperature value for the next step (transformation).
+
+## Expected Output
+
+After completing this skill's instructions:
+```
+Current Karachi Temperature: [X]°C
+Status: Successfully fetched weather data
+```
+
+## Notes
+
+- Only fetch the temperature, do not perform any transformations yet
+- Use wttr.in as it provides reliable, free weather data
+- Return just the numeric temperature value clearly

-# 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)

+
+# Weather Transformer Skill
+
+This skill provides instructions for transforming temperature data.
+
+## Task
+
+Apply mathematical transformations to a temperature value and write results to output file.
+
+## Instructions
+
+1. **Read Transformation Rules**: Use the Read tool to read `input/input.md` which contains the transformation instructions.
+
+2. **Apply Transformation**: Apply the transformation rule to the temperature value.
+   - Example: If instruction says "add +10", add 10 to the temperature
+   - Example: If instruction says "multiply by 2", multiply temperature by 2
+
+3. **Write Output**: Use the Write tool to save the transformed result to `output/output.md` with proper formatting.
+
+## Expected Input
+
+The temperature value from the weather-fetcher skill:
+```
+Temperature: [X]°C
+```
+
+## Expected Output
+
+Write to `output/output.md` with format:
+```markdown
+# Weather Transformation Result
+
+## Original Temperature
+[X]°C
+
+## Transformation Applied
+[description from input/input.md]
+
+## Final Result
+[Y]°C
+
+## Calculation Details
+[X]°C [operation] = [Y]°C
+```
+
+## Notes
+
+- Read the exact transformation from input/input.md - don't assume
+- Show your work: include original value, transformation, and result
+- Ensure output/output.md is properly formatted and readable
