L0NE8W0LF-1/ai-dataset-simplifier ? reverse-engineered prompt

Build me a Python tool that helps clean up messy CSV style datasets and gives me a simple quality report before and after cleaning.

I want to be able to load a pandas dataframe, get an overall data quality score, and see where the problems are, like missing values, inconsistent formats, duplicate rows, invalid values, and obvious logical mistakes. Then I want a cleaning helper that can automatically simplify the dataset by removing duplicates, standardizing column names, cleaning whitespace, handling missing values, fixing data types, removing redundant columns, and combining fragmented categories where possible.

Please make it easy to use from code, and also include a simple dashboard or web page if that fits the project. The output should clearly explain what was changed and give a short summary of the cleaned dataset. If you need to check current pandas docs or best practices online, feel free to do that.
