Explains why a file or code region exists by tracing its origins, later edits, companion files, and intent clues in local git history.
When to use it
Use when investigating why code exists, who introduced it, or what historical constraints matter before a rewrite or refactor.
Give it a repository and tracked file, optionally narrowed to current lines; it returns a historical explanation with confidence, evidence, and change risks.
