# Data Cleaning Instructions Generator

Generate precise data cleaning and transformation steps from a description of
the dataset, its quality issues, and the desired target format.

## When to Use

- Preparing raw data for analysis or machine learning pipelines
- Documenting data transformation logic for reproducibility
- Standardizing messy data from multiple sources
- Creating data cleaning scripts from natural language requirements
- Auditing data quality before loading into production systems

## The Technique

Describe the dataset, its known issues, the target format, and any business
rules that govern valid data. The model generates step-by-step cleaning
instructions — or executable code — that handles each issue systematically.
The key is being explicit about what "clean" means for your specific use case.
