# Code Formatter ## Overview Formats and validates code files using Prettier and related formatting tools. Supports JavaScript, TypeScript, JSON, CSS, Markdown, and many other file types. ## Prerequisites - Node.js (v16+) and npm/npx installed - Prettier available globally (`npm install -g prettier`) or locally in the project - Write permissions for target files and configuration directories - Supported file types present in the project (`.js`, `.jsx`, `.ts`, `.tsx`, `.json`, `.css`, `.md`) ## Instructions 1. Check whether Prettier is available by running `npx prettier --version`. If missing, install it locally with `npm install --save-dev prettier` or globally with `npm install -g prettier`. 2. Detect existing configuration by searching for `.prettierrc`, `.prettierrc.json`, `prettier.config.js`, or a `"prettier"` key in `package.json`. If no configuration exists, create a `.prettierrc` with sensible defaults (see `${CLAUDE_SKILL_DIR}/references/implementation.md`). 3. Run `npx prettier --check "**/*.{js,jsx,ts,tsx,json,css,md}" --ignore-path .prettierignore` to identify files that need formatting. Report the count and list of non-conforming files. 4. Apply formatting to identified files using `npx prettier --write` on the target paths. For single files, specify the exact path; for directories, use glob patterns. 5. Create or update `.prettierignore` to exclude generated outputs (`dist/`, `build/`, `*.min.js`, `*.min.css`), dependencies (`node_modules/`, `vendor/`), an...
