who_touched
Read-onlyIdempotent
Aggregate git blame results by author for a file. Displays line counts, commit counts, and primary owner. Optionally scope analysis to a specific line range.
Instructions
Read-only. Code ownership for a file via git blame, aggregated by author. Returns each author's line count, commit count, and most recent commit date, plus the primary_owner (most lines). Pass line_start/line_end to scope to one region (e.g. a single function). Errors if cwd is not a git repo or file is untracked. Cost scales with file size; instant for typical files.
