What problem does it solve? Codebases accumulate noisy comments that restate the code, narrate structure, or leave stale TODO notes, making files harder to read. This Skill defines a strict comment policy so every comment that survives explains a non-obvious "why" and nothing else. ## Core Features & Use Cases - Comment minimalism rules: Default to no comment; keep only one-line comments that explain non-obvious decisions, magic values, workarounds, or ordering constraints. - Smell Test and Keep Test: Concrete checklists for deciding whether to delete or retain a comment during editing or review. - Protected comment types: Preserves license headers, @ts-* and biome-ignore directives, and aria rationale comments. - Use Case: While reviewing a pull request in an Astro project, apply this Skill to strip per-element narration and section banners from .tsx and .astro files while keeping a comment explaining a deliberate workaround. ## Quick Start Review the comments in this file and remove any that fail the smell test while keeping only those that explain a non-obvious why.
