## Overview

Diffing is how we understand change: code reviews, config audits, data validation, plagiarism
checks. But raw diffs lie by omission — whitespace noise, reordered keys, semantically identical
reformatting. This skill covers choosing the right diff strategy: textual, semantic, and structural
comparison, plus review workflows that surface real changes.

## When to use

- Reviewing code or config changes

- Comparing document versions

- Validating data migrations or transformations
