Analyzes codebase size, language composition, and structural changes using Tokei and Difftastic.
This skill empowers Claude to provide high-level insights into repository structure and granular understanding of code changes. By integrating Tokei, it quickly calculates line counts and language distribution across a project, while Difftastic enables Abstract Syntax Tree (AST) aware comparisons that ignore trivial formatting changes. It is particularly useful for developers during refactoring, project onboarding, or code reviews where understanding the true impact of logic changes is more important than whitespace or style updates.
