Systematic Leakage-Free Feature Engineering
"Systematic Leakage-Free Feature Engineering" is a ready-made prompt from the Zayenha Prompt library in Programming & Tech, written for claude-sonnet-4-7. It has a main prompt to copy into the model, built-in quality guards, and a verification prompt to run in a second window to review the answer. The full text needs the Pro plan; the description is open to all.
Design a feature-engineering methodology that derives strong features, prevents leakage, and documents each one, handling temporal and categorical features correctly, without inventing functions.
Your current plan: free
Deriving features for a demand-forecasting model, improving a credit-scoring model's features while preventing leakage, documenting an auditable feature dictionary before handoff to modeling.
Built-in quality guards
No fabricated functions or claimed feature importance/causality without measurement
Avoid PDPL-violating features and printing sensitive data
Cover derivation, documentation, consistency, and importance evaluation without truncation
Adherence to the six-section structure and feature dictionary within a unified pipeline
Frequently asked questions
How do I use this prompt?
Copy the main prompt and paste it into claude-sonnet-4-7 or the model you use, replace what is in square brackets with your details, then run the verification prompt in a second window with the answer pasted in, and review it before relying on it.
Is this prompt free?
Its full text requires the Pro plan or higher. Free prompts you can copy at once without an account are on the ready-made Arabic prompts page.
Which model was this prompt written for?
It was written for claude-sonnet-4-7 and follows how that model works; you can run it on other models too, reviewing the result, since no single wording guarantees the best result on every model.
