🧹 Code Comment Cleaner

Review commented-out code before deleting it

Use Code Comment Cleaner to build a file-and-line preview of comment blocks that look like abandoned implementation across supported source files. It treats uncertain matches as review candidates, not proof of dead code.

Apply explicit preservation rules first

The workflow keeps blocks that match TODO, FIXME, NOTE, or XXX markers; license or copyright terms; and disabled-test patterns. It also preserves a narrow natural-language sentence pattern. Project-specific directives, docstrings, examples, generated sections, and unusual prose still need human review.

Require confirmation before a write

Preview mode changes nothing. Clean mode repeats the preview, asks for confirmation, creates a .bak beside each changed file, rechecks the proposed ranges, and removes only the reviewed blocks from bottom to top.

Cover eight language families

Rules are defined for JavaScript and TypeScript, Python, Java, Go, Rust, HTML, and CSS comment styles. Unknown file types require a decision before scanning.

Know the limitation

This is a procedural SKILL.md workflow with reference patterns, not a bundled parser or deterministic executable. Results depend on the agent's scanner implementation and can produce false positives or false negatives; review the diff and run the repository's normal checks afterward.
