+description: "Fixes messy columns: normalizes and cleans CSV data."
+instructions: |
+  1. Provide the path to your CSV file.
+  2. The recipe will scan all columns for type mismatches and missing values.
+  3. It will suggest fixes (or automatically apply them, depending on your choice).
+  4. Review the output and save your cleaned file.
+activities:
+  - Validate the input CSV file.
+  - Analyze columns for data quality issues (mixed types, missing values).
+  - Apply or suggest data cleaning and normalization fixes.
+  - Generate a summary report and the cleaned CSV file.
+  - Provide the cleaned CSV file with a "_cleaned" suffix.
+parameters:
+  - key: file_path

+    description: "Path to the CSV file you want to clean."
+  - key: auto_fix_decision

+prompt: |
+  You are a CSV cleaning assistant.
+  1.  First, validate that the file at {{ file_path }} exists and is a readable CSV. If not, inform the user and stop.
+  2.  Scan the file to identify columns with mixed data types, missing values, or formatting issues.
+  3.  Based on the {{ auto_fix_decision }} parameter, either suggest or apply fixes for the detected issues.
+  4.  For each fix, briefly explain the reasoning (e.g., "Converted 'Age' column to Integer because many values are numeric.").
+  5.  Provide a comprehensive summary of the changes and output the cleaned dataset.
