What problem does it solve? Codebases drift into inconsistent formatting, one-line conditionals, and accumulated dead code over time. This Skill standardizes how TypeScript and Astro code is written in this repo and provides a structured review lens for finding duplication, dead code, and unnecessary complexity. ## Core Features & Use Cases - Style conventions: Braced control flow with blank-line spacing, type over interface, naming rules for identifiers and files, minimal comments, ~/ path-alias imports, and Biome formatting. - Simplicity review: A complexity-only audit producing one-line findings tagged dup:, delete:, stdlib:, native:, shrink:, or speculative:, with grep-verified claims and a net line-count score. - Use Case: After writing a new Astro component, ask for a style pass to convert one-line if statements into braced blocks, fix import aliases, and then run a simplicity review on the diff to find copy-pasted helpers that should be extracted. ## Quick Start Review my recent TypeScript changes for code-style violations and run a simplicity review on the diff to find duplication and dead code.
