What problem does it solve? Codebases accumulate bloated comments that restate the code, narrate history, and bury the one useful fact. This Skill enforces a consistent commenting style so every comment says something the code cannot. ## Core Features & Use Cases - Comment review and rewriting: Trims doc blocks and inline comments to 1-4 lines focused on the why, cutting history, build-up, and restatement. - Doc block conventions: Keeps /** */ blocks on exported functions, types, and constants that state what the thing is and the one thing a caller could get wrong. - Preservation rules: Keeps lint directives, external links, formulas, and warnings that prevent bugs or data loss verbatim. - Use Case: While reviewing a TypeScript pull request, apply this Skill to condense a ten-line doc block into three lines that state the query reason, the consumer, and the caveat. ## Quick Start Review the comments in this file and rewrite any that restate the code or narrate history into short why-focused notes.
