Token Optimization

Expected range: 200–400 tokens (small project), 50 tokens (cache hit)

Caching: Caches comment patterns in .claude/cache/remove-comments/ for 7 days. Invalidated when source files change.

Early exit: Returns immediately if no comments are detected in changed files.

Patterns used: Grep-before-Read, early exit, git diff scope default, caching
